Frame is 14 5/8” wide, height is spring- adjustable from 77 1/4”” to 80 1/4”.
Dog opening is 7 1/2” x 13” high.
This frame is very high quality and pretty new, just bought last year for over $400 and barely used by our little 5 lb Pom. No defects. We just don’t need it anymore as we installed one thru the wall.
This frame is very easy to install/remove
(see the video, less than a minute!), and includes good weatherstripping.
