Frequently Asked Questions (FAQ)


I don't have a screen door so do I need to buy the Screen Door Adapter?

The primary function of the Screen Door Adapter is security for the glass door. Why? Without the adapter the sliding door will just butt up against the pet door, which leaves gaps for an intruder to attempt to pry open the doors. The adapter is a wall frame section that runs up the side of the pet door and creates a channel for the glass door to close into (and a screen door), like your wall frame, so the sliding door cannot be accessed for pry attempts. Second, gaps also means poorer weather and bug proofing and it is not as aesthetically pleasing. So if security and/or weather/proofing and/or aesthetics are important to you then you would want to get the adapter with the pet door. 




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

No it does not matter which way your doors open, the pet doors and locking system are universal and suit both left and right opening sliding doors. 




What if I have two sliding doors that close together- will it fit?

The pet door will work if you height is within the 199-211cm guidelines.

The video near the bottom of this FAQ page shows a door inserted in to double doors. You can see another example of a door inserted in to double doors in the main photo at the top of the home page.

However, there are a few things to be aware of with twin doors:

1. The original lock mechanisms will not tend to transfer onto the base model pet door with the screen door adapter because the catch plate on twin doors acts as a door handle and thus can't be removed. So, the only and easiest way to lock double doors using the existing locks is with the PatioLockTM model. 

1.1 If the PatioLockTM model is not purchased, the alternate locking options of twin doors involves either screwing and drilling re fitting patiobolts (key operated pins that screw onto your sliding door frame and a pin needs to be pushed up manually into a hole in the track to pin the sliding door against the pet door. $15ea from Hard Wares) or with rods cut and dropped in the floor tracks behind the sliding doors (a rod is included with the pet door that can be used for this purpose). Note the rods in the tracks are pretty crude and can be inconvenient to many.

2. The security screen doors (if there) won't lock together on twin doors because they need to remain open to let the flap swing. So, you lose the 'security' function of your security screen doors. If you buy an adapter you can often transfer the locks for the left security door into the adapter and with the PatioLockTM model, you can keep using the left door (usually) as the security door. 

3. In order to use one security or screen door as an insect door (ie., to let air in without letting mosquitoes/flies in), a Screen Door Adapter is needed. If you want to use both screen doors, then two Screen Door Adapters are needed.

So, just be aware of the locking issues for both the glass and security doors if you have twin doors. The PatioLockTM is the only convenient and security loaded option for twin doors on the market.



Will the PatioLockTM work on every type of sliding door lock?

The PatioLockTM will work with most common externally mounted sliding door handle lock mechanisms that have a hook/s that ROTATE out from the sliding door handle and lock into a catch plate on the wall frame.

Locks that do not have a rotating hook/s or that consist of internal mechanisms located inside the centre of the aluminium/timber door frames are not compatible with the PatioLockTM system. 

If you are not sure what type of lock you have or you think you may have an internal style lock, take a picture of the mechanism and email it through to us before you order to clarify lock compatibility.  



What if I have one of the internal locks - what options do I have?

The base model pet door with a screen door adapter can still work but you would need to use a patiobolt or rod in the floor track to lock/wedge the sliding door into the pet door. 

In some cases, you may be able to transfer the existing hook catcher located in the wall frame into the adapter if the distance from the centre of the screw to the inside edge of the channel the glass door closes into is between 8-12mm. Refer picture below for measurement guideline. It needs to be 8-12mm for the screw to locate inside the pet door frame correctly once the screen door adapter is fitted. To fit the base model and adapter in such a way requires handy skills and screwing etc to transfer the catcher.






I'm confused, should I buy the PatioLockTM Ultimate Security System or the Base model pet door for sliding doors?

If you are renting and/or not handy and/or time poor and/or prefer fast convenient installation/removal and/or have double sliding doors, then the PatioLockTM system is recommended.

The extra outlay for the ultimate model is less than half the cost of a professional installation charge associated with fitting the base model and you can also keep re-using the PatioLockTM model at multiple properties. This system really does offer the ultimate in security and convenience. 

If however, you have free access to someone handy and you are a home owner so screwing into the sliding door frame etc to secure the pet door is not a concern and you are also not planning on moving home and you have 3+ hours to spare, then the base model pet door with a Screen Door Adapter will lock the glass door securely. It needs to be disassembled though in order to be removed.   



How does the base model pet door secure into the sliding door frame when transferring locks & fitting the Screen Door Adapter?

Hardware is included to fix the pet door into the wall frame (door jamb). We also include pre-drilled holes inside the top panel of the pet door so it can be fixed up inside the top track for a second fixing point (tek screw included). 

You can see the bracket to secure the pet door in both the photos below. It is grey and on the right hand side of the pet door about half way up the door. These brackets are powder-coated the same colour as the pet door but the grey one was used to highlight it in the picture. The screw for the top panel is concealed up inside the top panel but pictures in the instructions are included. 




Will the pet door fit in the screen door track?

The pet door is a sliding glass door frame and so it is usually too fat/thick to fit into most screen door tracks in the wall. So, if you want to be able to use your screen door, then we recommend getting the screen door adapter. Security is also greatly enhanced with the Screen Door Adapter fitted so you can lock security screen doors on to the adapter by transferring the catchers from the sliding door frame into the adapter. If you think you would like the Screen Door Adapter, just select it as an option when you purchase your door in the checkout process.   




Will common external locks transfer on to the Screen Door Adapter?

Yes, locks for both the glass door and the screen/security door will transfer on to the Screen Adapter for locks that come out of the door handle. Please refer below to pic below as a reference for transferring common lock catch plates. Note it does not matter if your door opens to the left or right, the adapter fits on both sides of the pet door. 





What if my sliding door is outside the standard height range?

We stopped making custom doors 5 years ago. However, we have some black top slider panels that can be screwed on to the top of the standard pet door to make it as tall as you want. Each additional panel adds 13.5cm in height and they are $20 each. Please call to arrange this for you. You would need to measure the distance from the inside bottom of the floor track to the inside top of the top track and let us know and we make sure you order the correct amount.

Please note to do this you would need to screw (tech screw) or rivet the panels together yourself. Some handyman skill is needed to screw them together straight and square. 

If you have a different colour door then you could either use a pressure pack touch up can from a Hardware or get the top panel section re-powdercoated once you screwed/riveted it all together.

This option whilst involving a little tinkering is a very cheap way out of getting a high quality pet door for 'tall' sliding doors. 

Note that if you wanted to add the screen door adapter you would need to purchase an extra section of adapter to reach your desired height. You would also need to notch out slots in the side of the extra top panels to allow the adapter to insert into the extra top panels -  this requires some handy skills and tools (e.g., file/hacksaw/multitool).



Will the pet door fit a Timber sliding door system?

Yes. The pet door can be used in sliding doors for timber doors (timber screws not included). However, please note the timber sliding door will not fit inside the Screen Door Adapter because timber frames are too thick (38mm+) whereas the channel in the adapter is only 35mm wide. So, the screen door adapter can not be used with timber doors. 



Can the pet door be behind the fixed panel of glass in the sliding door rather than at the door opening end?

Most customers who have tried this have found they can't slide/move the fixed panel to put the pet door insert behind it in the centre track. If you can freely move the fixed panel then this may be an option but check you can do it first. Note you still lose the same amount of opening space once the pet door is installed. Sealing the pet door with the fixed panel could also be a challenge because the screen door adapter won't fit there. 




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

Stacker doors or multiple sliding glass door have unusually wide frames due to the extra sliding panels. The screen door adapter is only 100mm deep to suit standard (common) sliding door frames and thus the adapter will not extend far enough to capture the screen door.

The glass door can be locked if compatible with the PatioLockTM system (providing the stacker doors are single glazed standard door frames that are thinner than 33mm).

If you want to be able to use your screen door then modification to the standard adapter is required. Any rubber/aluminium section (e.g., 100x3mm) can be riveted or glued to the rear of the adapter to extend it to reach the screen door. Alternatively, a section of 1.0mm thick galv sheetmetal can be cut and folded (e.g., 130mm x 20mm x adapter length) by a local sheet metal worker and riveted to the rear of the adapter to make it capture both the glass and screen doors. This can then be sprayed the same colour as the pet door with a spray can from a hard ware. Please check to make sure you frames are not wider than 100mm before ordering unless you are willing to do some tinkering above or utilise a local tradesman/shop (e.g., sheetmetal worker).  



What if I have double-glazed sliding doors?

Double-glazed sliding doors tend to have much thicker frames than common sliding doors and thus they often do not fit inside the screen door adapter.

In these cases, the only solution is to get the pet door on its own and use an alternate means of locking the sliding door against the pet door because without the adapter the locks won't transfer (e.g., patiobolt, dowell in the track, etc).

Note the screen door will also not be able to be used unless the pet door is put in the screen door track. Please check to see if your doors are single or double glazed before ordering. If you are not sure, then just call 0431 908 929- generally double glazed frames are much thicker (e.g., thicker than 35mm).The channel in the adapter to capture the glass door is only 35mm wide, so your sliding door ideally needs to be thinner/less than approximately 33mm. 




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

The PatiolockTM system will still work to lock the sliding door if the locks are compatible (common sliding door locks) but the Screen Door Adapter will NOT work with the PatioLockTM system when the glass door is in the outer track. We do not know why builders install them this way as it makes no sense.

If you buy the base model with the screen door adapter and you can remove the catch plate from the wall frame, the you can usually locate the pet door as far out as it will go in the outside track and run the adapter backwards into the house. Some modification of the adapter may be needed if the catch plate does not align, so handy skill and possible modifications are required with this set up.  




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

Sliding door frames are typically ‘out of square’ by varying degrees. It is not noticeable with aluminium frames as the door closes in to a channel section that conceals how out of square the doorframe truly is.

If your doorframe is poorly constructed (not very square), there can be gaps between the pet door weather strip and the sliding door in some places (e.g., top or bottom of the sliding door). About 5% of doorframes we see are so out of square that a second weather strip is needed to pack out the gap. We include extra weather seal for this purpose but soft foam strips (e.g., 6mm wide x 10mm thick) can be bought from hardware stores for around $6, which work well (often only a strip of about 10-40cm is needed).




What is the overall width of the pet doors?

Small = 26.2cm

Medium = 32.2cm

Large = 37.2cm

Extra Large = 49.2cm




What if I want a custom colour?

Sorry, we no longer do custom colours due to high one-off costs.




Can the flap be locked to keep the pet in/out?  

Yes, each doggie door for sliding doors comes with a steel powder coated locker panel to lock the pet in or out. 




Will the pet door fit tightly inside the wall frame?

Sliding door frames vary from 15-40+mm in width so patio pet doors tend to locate around the centre ridge in the floor track and they can move back and forth if pushed by some millimetres but this is not a functional problem because it is a stationary panel. 



What is the Base Model Pet Door with the Screen Door Adapter?

The Base Model pet door for sliding doors with the Screen Door Adapter is the old way of securing the pet door and screen door and still works fine but involves screwing, drilling, cutting, tools, skills etc to install securely to lock up the glass door and security screen door if you have one. So, this set up allows for: 

1. Security: Existing locks can be transferred on to the pet door system so that you can continue to lock the sliding door AND the security/screen door to the pet door with the original locks for convenience, security and aesthetics. The pet door locks into the sliding door frame with a bracket and hardware (included) and the top panel of the pet door can also be tek screwed up into the top track for extra fixing strength (tek screw included). 

2. Screen Door Use: the screen door will also close into the side of the wide (10cm) Screen Door Adapter frame so that you can also use the screen/security door as per normal re locking and closing.   

Essenially, home owners and/or renters who are putting the pet door into a main living area tend to buy the either the PatioLockTM model or the base model with the Screen Door Adapter. The Adapter allows BOTH the glass and screen doors to lock and close into the pet door system. So, this maximises security and convenience as existing lock mechanisms are utilised and airflow can be let into the house without letting all the mosquitos and insects in. Check out our original post regarding the base model (Max Security package) Screen Door Adapter option below: 




What benefits will I get if I select the Screen Door Adapter at the checkout? 

As noted, there are a number of extra features when the pet door is combined with the screen door adapter. Just to clarify, the adapter is a universal doorframe section (16mm wide and 100mm deep  -  like the frame that runs up your wall that the sliding door closes in to) that you screw on to the side of the pet door to mimic the sliding door frame in your wall. 

If you are putting the pet door in a laundry door that you never see or use, then the pet door on its own is usually suffice unless you need to use your screen door for when the dryer is used (e.g., in winter) to prevent the room getting wet. The benefits of the screen door adapter accessory include:  

1. Functionality: If you want to continue to use your screen or security door for AIR FLOW in/out of your house then you will need the screen door adapter (note if you buy the pet door on its own, the screen door has to remain open for the flap to swing in and out of the house, which means it can no longer be used as flies/mosquitos will get through the gap between the pet door and the screen door if you open the sliding glass door). 

2. Security: If you want to continue to use your sliding door handle locking mechanism and screen/security door locks- The adapter copies the wall frame that your doors close in to on the wall, so transferring locks is possible using the base model or the PatioLockTM model locks are concealed behind the adapter so they are out of the way. You can not use your security or screen door without an adapter. 

3. Superior Weather Seal: -  gaps are hidden which improves weather seal and bug proofing capacity.

4. Aesthetics/Design/Looks: gaps are hidden which looks better, particularly in main living/entertainment areas.
