Liberty Custom Pet Door Patio Panel

It is meant to easily be put in and removed. You just have to loosen the screws at the top, fit it into the track, and then tighten them. Then to remove it you simply loosen them again and pop it out.

We do include a c-clamp lock. It is not designed to mate with your existing sliding door lock. You can also use a Charley-Bar or dowel in the track.

This door has superior insulating capabilities. The double flaps have magnets that seal all the way around, and will stay closed in wind gusts up to 50mph. The Low-e glass also compliments the insulating value of you new vinyl door. It is our #1 recommendation for extreme climates.

Yes, the endura flap 3e is compatible with most vinyl sliding patio doors for a vinyl-pet slider that matches your existing track. At 1" thick, it is thicker than most aluminum panels, so it will fit better in a vinyl track. The track width may not line up exactly with the panel, but it is only an issue with the aesthetics, not functionality.

Installation can work the same way as with standard sliding doors. In order for the panel insert to remain secure and stable, you will need to make one of your sliders stationary. In essence, you will only be allowed to slide and walk through one of your two sliders.

Measure from the innermost part of the bottom track to the innermost top part of the track. If there is a pencil railing, include that in the measurement because the panel straddles the railing.

The primary differences between vinyl and aluminum dog doors for sliding patio doors besides the material they are made out ofare in their thickness, energy efficiency, and material compatibility. Vinyl doors are typically 1.5" thick, offer better insulation, and match well with vinyl sliding doors due to their energy-efficient nature and thicker frames. Aluminum doors, on the other hand, are 1" thick, less insulating but highly durable, and they pair well with aluminum sliding doors for a consistent look and maintenance ease. \n \n When choosing between them, we recommend getting the panel that matches your sliding glass door's track material (aluminum with aluminum, or vinyl with vinyl) and will fit into your track's width.

While it's possible, a more suitable option would be the Liberty Pet Door for Horizontal Sliding Windows, which is already available in standard window sizes.

Yes, the Endura Flap has been tested in -40°F. The dual-pane glass provides excellent insulation value.

Some sliding glass door tracks have a triangle-shaped guide rail instead of a cylindrical pencil rail running along the middle. This pet door panel has an arch along the bottom that is designed to sit on top of a cylindrical pencil rail. Pencil rails are shorter in height than triangular guide rails, which means that the pet door panel would wobble on top of it rather than sitting flush with the rest of the track. To accommodate the pet door panel you will need to build up the sides of the triangular guide rail so that the tip is less than ¼” tall. Please reach out to customer service if you have any questions about this process.

If none of these sizes will fit your door, you can order a custom fit Endura Flap Thermo Panel 3e.

That column is what we recommend be the range of pet height that would be suitable for that particular flap size. So for example if you pet is 20"tall and could fit though a 10" wide opening, then you could go with the large flap.

The Endura Flap Thermo Panel 3e is 1" thick. It is only thick enough for a single flap, not a double flap.

Anderson and Pella sliding glass doors have an inner track wall but no outer track wall. Additionally, the pencil rail is on the outer edge of the track rather than in the middle. Since this pet door panel is designed to sit between two track walls and on top of a centered pencil rail, it cannot be installed in Anderson or Pella doors without modifications. We recommend building out your track and using L brackets or toenailing to secure the bottom of the panel to the inner track wall. Building out the track means adding a piece of wood or vinyl that is the same height as the pencil rail to the space next to the pencil rail. This creates a flat surface for the pet door panel to sit on. Next, you will need to secure the panel to the track wall. To do this, you can use L brackets or you can toenail the panel into the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss this process or different options for an Anderson or Pella sliding door.
