Description

The paintable plastic frame allows you to match your door’s existing color. Easily fits into standard-size paneled, wood, metal, and PVC doors 1 5/8 in – 2 1/4 in thick. A snap-on closing panel keeps your pet from using the door; use a second closing panel (sold separately) for an additional layer of weather protection. The unique three flap system is more energy-efficient than traditional single flap doors. Great for hot and cold climates, the center insulated flap helps keep extremely warm and cool air outside of your home.

Regarding the size standard of the opening when installing: the large opening height is 21.5cm and the width is 19.5cm; the medium and small opening height is 17.5cm and the width is 16.5cm; in addition, if the glass is installed, it can be opened again, as long as it is smaller than the cat. The outer dimensions of the door are OK, because there is no need to make screw holes on the mounting glass, and directly glue the glass glue or super glue!
