Endura Flap Thermo Panel 3e Pet Door for patio doors is manufactured for aluminum sliding glass doors, with U-shaped tracks at least 1 in. in width. They can be installed in vinyl patio doors with U-shaped tracks but may need shimming to secure it. This energy-efficient patio door panel has LoE glass and the Endura Flap Pet Door surrounded by a sturdy aluminum frame. The Thermo Panel 3e doesn’t require a drill or other tools for normal installation. It is built with a 3 in. spring-loaded height adjustment piece for ease of installation and removal.

The pet door has an exclusive user-adjustable step-over to better match top of pet door opening to pet height. Available in three colors White, Dark Bronze and Brushed Aluminum.
