Best Door on the Market!

“We’re really impressed with this pet door. It’s super sturdy, the double-locking function is excellent, and we love that it doesn’t cause any permanent damage to the door. The large opening is a great size for bigger dogs, feels really solid, and is very well made. Two thumbs up!”

COMMON QUESTIONS

Common Questions About PatioLock™

Click a question below to view the answer.

Do I need to transfer my existing sliding-door locks?

No. The PatioLock™ model is desiged to lock common one and two rotating hook sliding door locks. Refer to the pictures in the checklist at the top of the page for reference. Flick the lever and one or two hooks usually rotate out from the side of the door handle itself (not from inside the aluminum door frame). Your existing glass-door handle and wall-frame striker stay where they are- you DO NOT need to transfer or touch them.

Do I need the Adjustable Screen Door Adapter if I do not have a screen door?

The adjustable adapter provides a channel for your glass door to close in to, like your wall frame. This is needed to seal and secure the glass door and hide gaps and locks. It also helps cover the joins, improve weather and insect sealing and looks better aesthetically as no unsightly weather seals are required. So, we strongly recommend getting the screen door adapter even if you do not have a screen door.

Will the PatioLock model lock to every type of sliding door lock?

No, it is only design to lock to common one or two hook locks that rotate outward from the door-handle assembly when you operate the lever on the handle. If your sliding door latches on to a hook type striker located INSIDE the channel in the wall frame, then the PatioLock will not work. You would need a base model set up- refer to the FAQ question about internal locks.

What if my sliding doors are taller than 2.1m?

If your frame height is more than 200-211cm then your doors are not standard (e.g., 2.35m; 2.65m) and you will need Height Extension Kit/s fitted to make the pet door system taller. Each kit raises the pet door 30cm and comes with an extra short length of screen door adapter and weather seal for the rear of the sliding door. Please NOTE: Handy skills and tools are required to fit extension kits to the pet door. The PatioLock model can still lock in place without screwing into your frames if the glass door frame the handle is screwed on to is a common 20-32mm thick frame.

NOTE: Some commercial sound-proof frames for apartments use much thicker frames (40mm) and these do not fit inside the screen door adapter, so email pics of your locks/frames/floor-tracks if you are unsure and we can highlight options.

Does it matter if my sliding doors open to the left or to the right?

No, it does not matter which way your door opens. The PatioLock model can be configured for doors opening to the left and right. As long as you have the common one or two rotating hook door handle locks set at standard heights (i.e., it is not a sliding door with access to a pool area with much higher locks), then the system will adjust to suit the height and opening direction of your door and locks.

Can I remove the insert and lock my home normally again?

Yes. Because your original glass-door locking points stay in place, the insert can be removed and your glass sliding door can lock normally again within seconds. This is great for renters (no damage to property and can be re-used over and over again) and also if you are going away or entertaining as the pet door has the security benefits of your existing locks but with the convenience of being able to be removed in seconds. So, you can secure your home immediately with the glass door locking as per usual. Store the pet door in the garage whilst away or entertaining.

Can my security-screen lock be transferred to the Adjustable Screen Door Adapter?

A common security-screen striker can be moved from the wall frame in to the screen door adapter if you want your screen door to be locked. Note the glass door locks already, so some customers just use their security screen door like a fly screen and not bother transferring the lock mechanism for the screen. However, if you want the security screen to lock and the security screen is on the outer track, then you can transfer it into the adapter. Unlike the glass-door connection, this optional screen-door work needs a few screws and a drill driver.

How do I transfer the lock for my screen door?

For common security screens on the outside track, remove the striker/s from the wall frame, put some double-sided tape on the back of the striker, push it inside the screen door handle frame/lock, then close the screen door once you have fitted the pet door and screen door adapter. Hold screen closed with pressure for 5-10 seconds, then unlock screen door and open it. The double-sided tape will hold the striker in the correct position, then just use a few tek screws of M4 bolts x 10mm long with some lock nuts so it is tamper proof. Done. When you move, unscrew from adapter and put it back in the original spot on the wall with the original screws (store these somewhere safe).

What if I have more than one sliding glass panel (stacker doors)?

Stacker doors are not all constructed alike. Track layout, frame thickness and where the locking panel sits determine compatibility. Send us photos of the open and closed doors as well as the handle for us to check. However, if your glass door frame is the common 20-32mm thickness, and your glass door is on the inside track, then the PatioLock model will lock the glass door without screwing if it also has a common one or two rotating hook lock on the door handle. Depending on your frame depth (ie., how many panels you have that slide), some customers leave the screen door ajar level with the pet door as there can often only be a small gap of up to a cm or two (e.g., if your frames are only 13cm deep). If your frames are deeper than 13cm, then some customers add a rubber strip to the screen door adapter (this only goes out 10cm), or some others get a custom bit of flashing made to create an extra 'L' shaped extension out past the adapter to capture the screen- this obviously involves some local sheet metal fab shop to cut and fold it for you re instructions below.

Measure the gap between your top and bottom track in millimetres - leave a few mm for cutting tolerance (e.g., 2037mm). Fit pet door and adapter. Measure from the outside face of the pet door frame to the outside edge of your screen door channel (e.g., 145mm). Measure how deep the channel is on your wall frame that your screen door closes in to (e.g., 15mm). So, you would ask for an offcut of 1.2-2.0mm galv sheet metal to be guillotined and folded 2037 long, 145mm wide and with a 14mm 90 degree fold - this is the shape of an 'L'. Then this flashing can be riveted or screwed on to the back of the screen door adapter so it extends from the pet door frame all the way out to the screen door track for the screen to close in to. Spray same colour as pet door before fixing. Satin Black. Pearl white. Primrose or Anotec Silver-grey are the powder coat colours from the Dulux paint range. This is usually quite cheap to do as an offcut from a 2400mm long sheet is usually used and it is not expensive material.

What if my glass door is on the outside track and my screen door is on the inside track?

If your glass door is on the outside track, then you have a few options. You can either use the Patio Lock model with the lock kit if the door handle has a common one or two rotating hook lock. However, you cannot use the screen door adapter. Note without the screen door adapter, the sliding door will just butt up against the pet door so it is not as secure and you may have gaps between the pet door and the sliding door. The locks will also overhang the pet door, so you need to be careful entering the house that the locks do not catch on your clothes or your arm (the adapter also hides lock mechanisms). Unfortuantely, if your doors have been installed backwards, you cam not use the adapter with the no-screwing Patiolock Model. Option 2: If you are allowed to screw into the sliding door frame, then you can get the base model pet door with a screen door adpater and you use the brackets and hardware included to transfer locks from the wall frame into the screen door adapter. Then you can use your glass door and screen if you have one normally but obviously you need to be allowed to put screws into the sliding door frame and have handy skills and tools to do this.

What if I have rare internal style locks?

If your sliding door locks onto a striker located inside the channel in the wall frame that the glass door closes in to, then you will need to check a few things to see if the base model pet door will work.

1. Measure from the inside of the channel, closest to the inside of the house, to the centre of the screw that's holding the striker in the channel. If this measurement is between 8 to 12 millimetres, then you can transfer this striker into the screen door adapter so that the glass door will lock using the existing glass door handle lock mechanism- this is most convenient but requires screwing the pet door into the wall frame with hardware included and handyman skills and tools to screw and transfer locks.

2. If the screw measurement is more than 12 millimetres, then you will not be able to transfer the lock mechanism for this glass door. Alternatives, like fitting a patiobolt or using a rod in the floor track would be needed.

3. For sliding doors that have frames thicker than 32mm, the glass door won't fit inside the screen door adapter. Our system is designed for common single glazed doors or thin-framed double glazed door, not thick commercial sound proof frames. In these cases, the screen door adapter is still recommended to hide a 'D' shaped rubber seal inside the adapter so when the glass door butts up against the adapter, the seal compresses and is hidden inside the channel in the adapter- so this looks better than not having an adapter and having weather seals visible between the pet door and sliding door. If you are unsure how thick your frames are, email us pics of your handles, frames, and floor track and we will let you know options.

Will there be any gaps once the pet door is installed without an adapter?

Without the Adjustable Screen Door Adapter, a visible join will remain between the panel and your sliding door. The adapter supplies a closing channel intended to improve the seal, appearance and protection around that join, like your wall frame, this is why we recommend it.

Sometimes sliding door frames can be out of square and the roller heights on the front and rear rollers can be maladjusted to keep the sliding door rolling on an unnecessary angle. So, you can close gaps by adjusting roller heights on your sliding door. For example, lowering the front roller height (screwdriver through a small hole in front and rear of your sliding door frame - youtube it) will close gaps at the top of the pet door. Lowering your rear roller can close gaps at the bottom of the pet door. You can also adjust both to get maximum changes of up to 20-30mm or more. In most cases, the screen door adapter will hide small gaps, just like your wall frame. If not, either kick the bottom of the pet door out to meet the sliding door and/or adjust the roller height on the sliding door.

If I’m not sure, can I email photos of my door frame, wall frame, floor track and locks?

Yes. Send clear photos of your sliding-door handle and locks, the wall frame and striker, and the floor tracks to sales@modernpetdoors.com.au. We can check them for you before you order.

Original explanation of PatioLock and its two locks

Why is our patented PatioLock model the ONLY option if you want Security with NO screwing and NO Handyskills?

1000s of happy customers have benefited from our patented PatioLock model because it is the ONLY insert in the world that can lock itself in to your sliding door system with NO screwing, NO cutting, NO drilling, and NO handyskills using your existing locks. It is the most secure way of locking a pet door panel.

How is it possible for the PatioLock model to lock without screwing?

We invested heavily into R&D and our team successfully developed an insert that locks itself on to your sliding door system!

Check out the quick video below to see the locks on both sides of the pet door in action!

Our PatioLock model has its own patented hook and catch locks. The kit fits to the pet door with simple allen keys provided and it doesn't matter if your door opens to the left or right. The kit includes:

Hook Lock: Locks the pet door to your existing catcher/stirker on the wall. Half the locking done. Easy.

Catch Lock: Your door handle locks into our catch/striker. Done. Fully Locked with No Screwing/cutting/drilling/skills/tools or transferring of your locks required!

Please note this is the ONLY pet door insert that can do this.

The patented self-locking capacity saves you hassles, time, and installation costs as no handy skills are needed. It is a game changer.

Question 1: Now you have discovered the PatioLock model can lock your glass door without screwing and handy skills, why would you buy a different brand pet door insert that is going to require screwing and brackets etc to lock the glass door? It just doesn't make sense.

Question 2: Why spend time or have to pay for someone to mess around transferring locks and leaving holes everywhere like you have to do with ALL the other pet door for sliding doors on the market when you no longer have to if you buy a PatioLock model for your home and pet?

The PatioLock model offers you the most value and convenience and security without all the screwing and hassles...

Five original consumer problems: full explanation

Are you aware of the 5 major problems with ALL the other brand patio pet doors that our PatioLock model solved?

In order to help you make an informed decision we thought it would be helpful to outline the 5 major problems with ALL other brand pet doors that we solved with our patented PatioLock model. This includes brands that advertise 'locks' or 'lock brackets' or 'security packs'.

Consumer Problem 1: Hard Ware and Pet Shop brand Issues:

They are not only made cheaply (materials/design) to allow retailers 100-160% mark up but they have many other disadvantages including:

  • You can't lock the glass door.
  • You can't use your screen door.
  • They do not seal well.
  • They are not very secure.
  • There is no screen door adapter option to enhance security & sealing.
  • They tend to come in silver only.
  • A cheap and flimsy two-piece frame design is used to save retail packaging space (shorter boxes) on shelves for the retailers benefit at the expense of your security (we use single-piece frames which are stronger and look better).
  • Limited/Problematic flap sizes: a short flap with a TALL rise (bottom rail) is often used which is PROBLEMATIC for most pets, especially when old/mobile.
  • Limited 12 month warranty.

Consumer Problem 2: Other brands that advertise 'lock brackets' and 'security packs' etc ALL require you to SCREW the pet door in to the wall frame. Not an option for renters or good for home owners because it leaves HOLES in the sliding door frame AND the pet door.

Consumer Problem 3: MORE SCREWING is needed to transfer the glass door lock from the wall to various brackets. This means more holes & unsightly gaps in paintwork on the wall where the lock was.

Consumer Problem 4: Handy skills & tools & time are needed to instal. Handyman costs are expensive ($250-$500).

Consumer Problem 5: Inconvenient & difficult to remove. Because ALL other brands require SCREWING it all needs to be unscrewed and dismantled to remove the pet door. Locks need to be transferred back to their original position. This is a problem if you are going away for a short holiday or entertaining or moving houses and need the pet door removed/replaced.

Overall, if you research and look into the details before you buy, you will learn ALL other brands have these problems that you can simply avoid by buying our patented PatioLock model solution.

Full original security, convenience and removal benefits

If you are ready to buy, scroll down this page to the Order Checklist Steps to make sure your locks and sliding doors are common/compatible, then fill out the drop down boxes at the top of the page to place your order.

Why does our PatioLock model offer you the Ultimate in Security and Convenience compared to all other patio pet doors?

Our patented PatioLock model is truly unique and offers you many unrivalled benefits including:

  • You no longer need to drill holes in your sliding door system.
  • You no longer need to drill holes in to the pet door and wall frame with brackets of sorts.
  • You no longer need to transfer your existing lock from the wall frame on to brackets/adapter which also leaves unsightly gaps in paint work on the wall.
  • Not having to screw is great for renters and home owners because you are not damaging the property in any way.
  • You no longer need to have tools and handy skills to try and lock the glass door.
  • You no longer need to potentially pay $200-500 for a handyman to install brackets and transfer locks and cut adapters to length to get a pet door to lock your glass door. This alone is a great savings.
  • If you move house, you do not need to buy another screen door adapter as we have the only adjustable one that does not require cutting and can be re-used on different height sliding doors.
  • You get the convenience of using your existing sliding door handle to open/close/lock the glass door to the pet door. No bending over to get a rod in and out of the floor track.
  • You can easily and quickly unlock and remove the pet door in seconds and instantly lock your glass door: great for when you are entertaining, moving house or going away for a holiday as you can immediately lock the glass door.
  • You can take the system to your pet sitter for temporary use with security whilst you go away if they have a common sliding door system.
  • You can keep using the system when you move house because the locks are fully adjustable and universal. It doesn't matter if your door opens to the left or right or if you hook/s rotate upwards or downwards- we got it covered.
  • The PatioLock system is made in Australia so you are getting premium quality and also supporting local industry.

Watch below for a more detailed overview of the PatioLock model and Adjustable Screen Door Adapter:

Do I need the Adjustable Screen Door Adapter even if i don't have/use or care about my screen door?

As noted, the adapter primarily seals and secures the GLASS door, so it is strongly recommended you buy the adapter regardless of whether you have/use the screen door. Other benefits include:

  • Minimises pry risk of the glass door.
  • Aids bug proofing.
  • Aids weather proofing.
  • Hides gaps between the glass door and pet door.
  • Conceals the locks so you don't capture your arm/clothes when entering the house (the locks overhang the pet door frame without the adapter on).
  • Aesthetics are greatly improved as gaps are hidden.
  • Allows for screen door use to let air into the house without letting all the insects in.
  • Adjusts in height so can be re-used at multiple properties
  • Does not require cutting or handy skills to fit (a rubber mallet is best to fit it- $3 from hard wares)
  • Security screen can be locked (striker can be transferred from wall frame into adapter with a few screws- a drill-driver needed for this step)

Basically, the integrity of the security and lock system is designed to go with the screen door adapter, so we advise you to buy it if you want it all to work and function as designed/intended, regardless of whether you have a screen door or not.

Most customers now buy the PatioLock model and for good reasons:

It's a simple and popular choice because there are numerous benefits you will gain over all other pet doors for sliding doors on the market. These differences are not small either, it is a major and unique selling point to lock with the ultimate in security and convenience with:

  • NO screwing!
  • NO cutting!
  • NO Drilling!
  • NO Handy skills!
  • Fully adjustable so multiple use for if/when you move home!
  • Fast installation.
  • No handyman costs!
  • Fast removal and glass door immediately locks.
  • Great for both renters and home owners.
  • No damage to frame or paintwork removing/transferring lock mechanisms.
  • No need for extra hard ware, brackets, rods and other contraptions/gimmicks.

Treat yourself with the Ultimate in Security and Convenience.

Original order checklist: rotating hooks and unusual locks

I want to buy myself a PatioLock model- what do I have to check before ordering?

Run through the order checklist below and then select your options at the top of this page.

Order Checklist Steps:

Step 1: Do you have a common ONE or TWO rotating hook lock?

Open your sliding door and flick the lever on your door handle. Notice if ONE or TWO hooks ROTATE out from the side of the door handle.

Reference your lock against those in the pictures below. Green is good!

Tip: you may have to push and hold a little pin in with your finger for two hook locks to release their hooks.

Step 1.1: What if my lock does NOT match the above one/two rotating hooks?

Some rare sliding door handles do not have rotating hooks, but rather the whole handle slides up and down. This type of lock even though it has a single hook, can work with the TWO hook lockset PatioLock model with some modification, so you would order the TWO hook lock for this style lock.

However, if you doors have INTERNAL style locks like those in the pics below with the red X through them, then the PatioLock model will NOT work. Take a close look and NOTICE the lock mechanisms are INSIDE the aluminium frame, they are NOT located in the handle frame like the pics with the green tics above.

If your door has internal locks, then refer to the FAQ page item on internal locks and check if the base model with a screen door adapter will work.

If you are insure, you can always email a picture through the contact us page or email and we can advise options for you.

Original measurements: wall depth, height and extension kits

Step 2: Check the wall frame is 10cm or LESS, from left to right.

Measure across the frame externally, from inside the house to the outside edge of the screen door track as per the picture below. Do NOT include the catch plate/lock mechanism mounted on the wall.

This is ideally 10cm or less for the adapter to work well.

Step 3. Check the 199-211cm height range of your sliding door frame as per vid or picture below.

If your doors are taller than 2.1m, then extension kits are available to extend the door. One kit gets you to 2.4m. Two kits to 2.7m.

It is important to check a. & b. below:

a. Inside bottom of glass door floor track to the LOWEST point of the top track needs to be 199cm or more (re red arrow below).

b. The inside bottom to inside top needs to be 211cm or less re blue arrow.

Original flap sizing and measurements

Step 4: Selecting the correct flap size for your pet:

Measure your pet's shoulder WIDTH and HEIGHT then refer to the table below. General Flap Info:

  • Measure your pet, do not use weight for a guide.
  • Cats are fine with any size flap.
  • Bottom rail is only 5cm tall on ALL flap sizes.
  • Flap HEIGHT is from GROUND to top of flap - this is the important figure to check against your pet's shoulder height.
  • Flaps are clear flexible polycarbonate.
Flap SizeFlap Width (cm)Flap Height (cm from ground to top of flap)
Medium22cm41cm
Large27cm61cm
XL39cm71cm
Original colour options and availability notices (historical)

STEP 5: Colour

Please note only white in the medium and large flap size is currently in stock.

Black, Primrose and Silver-grey doors are on back order until December 2026.

If you want to order a door that is on back order, just put the order through and we will send it out as soon as possible.You will receive and automated email with tracking info when it is shipped.

Older stock and back-order dates above are archival and may no longer be current. Use the current product selector and shipping updates.
Original adapter and freight information (check current charges)

Step 6: Adding the Adjustable Screen Door adapter to the cart:

The name of the Screen Door Adapter is rather misleading as its primary function is to seal and secure the glass door, just like the channel in the wall frame that the glass door closes in to. We strongly recommend getting the adapter even if you don't have/use your screen.

If you do have a screen door, then you will get the added benefit of being able to use the screen door to let air in/out of the house to aid heating/cooling without letting all the insects in.

It is much cheaper ($91 vs over $200) to order the adapter when you order your PatioLock model, so add the adapter to the cart with the drop down box at the top of this page (after pet door colour and flap size) if you want to maximise security and sealing and screen use.

Step 7: Shipping costs:

Free or flat-rate shipping is no longer possible Australia-wide because the pet doors are over 1.8m long, which classes them as over-size freight that generates manual handling surcharges in addition to domestic delivery surcharges, fuel levies and the actual courier fee.

Many of the large couriers have stopped doing over-size freight so we use different couriers depending on your exact location within Australia.

We are able to have a few zones per se in the check out step to try and streamline some of the courier pricing but if you live in rural towns then please select the $1 freight option and we will invoice you the courier price once we get the quote back. If you prefer you can email what you want and the address and we can quote before putting the order through. We do not put any mark up on freight so the price will be the same whether you order before or after.

Unfortunately, it is not possible to use an accurate freight calculator at checkout as we can't just use one company that could provide prices. The zone model is the best system we can come up with thus far to try and span some of the more populated regions.

For current delivery zones, freight, product prices and dispatch estimates, use the live ordering options and checkout. Older amounts above are retained from the original description for reference.
Original information about flap locks and moving house

CLICK below to BUY your own PatioLockTM Pet Door:

Can I lock the flap?

Yes, you can see the steel powder coated lock panel and lock system in the picture below.

Did you know the PatioLock model offers more Security than the old dated method of transferring locks?

Without boring you with engineering details, the PatioLock model uses the existing locks and the way your locks are mounted on the frame in their original position is typically stronger compared to the direction of the screws and pull-out force required when using brackets when locks are transferred.

What if I move house, can I re-use the PatioLock model?

Yes, you can because the PatioLock model is fully adjustable and universal which means you can keep reusing it if/when you move homes and because no screwing is involved it is perfect for renters and home owners because you won't be leaving screw holes everywhere!

Again, please note, the Screen Door Adapter name is somewhat misleading, its main function is to seal and secure the GLASS door, so we strongly recommend getting the adapter even if you do not use/have a screen door.

Our patented adapter is also the only adjustable adapter on the market, which means you can keep re-using this as well if/when you move homes.

What happens if my current house has a one hook lock and I move to a house that requires a two hook lock, or vice versa?

The lock kits can be ordered separately to accommodate moving homes. However, 80% of houses have a single hook lock, so if you have a single, you have a high probability of being able to keep using that at multiple properties.
