The Patio Pet Doors work with nearly all sliding and screen doors, Timber and Aluminium (including Crimsafe). The height usually isn't an issue as they are adjustable and we also have extension pieces available.
Most locks can also be integrated with the panels. To integrate locks and see what locks would be best for you see our locking help page here.
The inserts do not work with Bifold doors or typical swing doors.
If you think your doors may be unusual you can email us some photos and we can advise you further and help with locking options. [email protected]
