About this item
- Attention Before Purchase: Our 3 flap xlarge glass dog door has a fixed - swing mechanism. If it's installed on the left side of the glass door, it can only open inward. If installed on the right side, it can only open outward. This is non - adjustable because of the design structure. Also, note that installation demands using a drill to bore holes in the door frame.
- Superior Insulation & Weather Protection: The 3-flap xlarge pet door for sliding glass combines advanced insulation technology with a triple-flap system and double magnetic closures—locking out drafts, rain, and wind while keeping your home energy-efficient.
- Perfect for XLarge Pets: Our sliding glass door pet door features a semi - transparent flap that measures 13.4” wide by 23.7”high. This size provides a clear view and easy passage for pets weighing up to 220 pounds. Additionally, it comes with a safety lock, enhancing home security while allowing you to control your pet's access.
- Adjustable Height: The xlarge doggie door for the sliding door frame adjusts from 75 7/8" to 81" in height, with a glass door width of 18.1". This fits most villa and patio sliding glass doors. To ensure the correct height, measure from the top track to the inner bottom track of your aluminum sliding door frame.
- Openable Design: Our 3 flap dog door for sliding glass doors opens inward to maximize limited space, making it easy for people to move items in and out of the backyard. Additionally, we've filed for a patent.
