Good product

The Liberty Pet Door for a White Horizontal Sliding Window works well. The pet door is made of quality material. We had no problems installing the pet door. My recommendation is to double check your window measurements to ensure you are ordering the correct size pet door.

Alternative Installation Option (Staff Review)

A terrific option for windows that slide left-to-right. It has a beefy frame, safety glass and a thick, magnetically-sealed vinyl flap. It offers energy efficiency due to the flap having modulating magnets on all three opening sides to keep the flap closed and weather stripping between the flap and frame for increased insulation. It comes with a locking cover to keep your pets in and others out. It is available in 3 generous flap sizes. The panel is offered in a variety of heights (custom height option available). It is easy to install and remove when you don't need to use it. It comes with weather stripping and a vinyl draft stopper seal for added insulation. It is backed by a three year warranty.
