This attractive, high-quality patio pet door inserts into the frame of your sliding glass door and automatically adjusts to the proper height.

The panel can be installed in the left or right door, and it has an UltraSeal energy-conserving flexible flap system to reduce energy loss. Best of all, continue to use your slider as a "people" door.

Panels are available in four sizes that fit up to 81" tall sliding glass doors. (Panels for sliding glass doors up to 96" tall are also available - See Deluxe Pet Panel - 93" to 96").
