Hakuna Pets Dog Door for Sliding Glass Door - Tempered Glass Patio Insert

Hakuna Pets Dog Door for Sliding Glass Door - Tempered Glass Patio Insert

• DOG & CAT DOOR FOR SLIDING GLASS DOOR - Tempered glass insert that drops into an aluminum sliding patio door track and gives medium dogs and cats their own way out to the yard or patio - a sliding glass pet door that looks like part of the door, not a bulky plastic flap, while the slider still opens normally for you.
• MEDIUM FLAP 8.9" X 12", PETS UP TO 45 LB - A 8.9"W x 12"H flap with a 3.9" step-over fits medium dogs and cats up to 45 lb; it works as a cat door for sliding glass door and a medium dog door for sliding glass door in one. Measure your pet width and shoulder height; for very large dogs choose Large, or for cats and small dogs the Small size.
• NO-DRILL RENTAL-SAFE OR PERMANENT, LOCKABLE - A spring-jack pressure mount installs with no drilling and no damage for renters and apartments, or screw it in permanently with the included brackets. A metal locking security panel slides in to close off access and add home security. Tube spanner, hardware and manual included.
• SEE-THROUGH TEMPERED GLASS, SELF-CLOSING & WEATHER-SEALED - 3mm tempered glass in a rust-resistant aluminum frame keeps your light and view. A magnetic self-closing flap plus rubber and foam seal strips block drafts, wind, rain and bugs at the frame, and the flap settles shut on its own after every pass.
• FITS ALUMINUM SLIDING DOORS 77.2"-83.5", 5-YEAR WARRANTY - The 12.4"W frame fits Track-Lip & U-Channel sliding tracks (up to ~107.6" with add-on extensions, sold separately); it does NOT fit Flush, Narrow or Bifold tracks, or wall, window, screen or wooden doors. Ships in Black (also White and Cream), backed by a 5-year warranty.
