Locking Hardware

1. Check Your Existing Handle and Lock:

Examine the type of handle and lock installed on your sliding door. In some cases, internal locking hardware within the door track may obstruct the proper installation of the pet door. 

2. Removing Obstructing Hardware: 

If such hardware is present, you may need to remove it to allow the pet door to fit. This hardware is usually secured with screws, which can be unscrewed to remove the components. 

3. Consider Security:

Removing the locking hardware may prevent you from securing your sliding door. It's important to consider this before proceeding.

Tip: Use a Sliding Door Bar Lock as an alternative security solution. It's easy to install and allows you to keep your door secure without relying on the original lock.

Incompatible Door Heights

With the V1 Glass Patio Pet Door (2023 > June 25') some door heights cannot be accommodated due to extension limitations (i.e., one extension is insufficient, and two are too tall). This issue has been resolved with the release of our V2 Glass Patio Pet Door ( June 2025 > )
