We do not recommend installing the patio pet door in a double sliding door setup. The product is designed to be held in place with pressure and stabilised using the vertical edge track of a single sliding door. In a dual sliding setup where the doors meet in the middle, there’s no edge track to support proper installation. This can lead to an unstable fit and unwanted gaps.
For best performance and safety, we recommend installing the pet door in a single sliding door where the edge track can securely hold the unit in place.
