About This Automatic Sliding Glass Dog Door: Aiday Xlarge electric doggy door comes with 2 exclusive sensor collars—only your pet triggers entry (no strays, cats, or raccoons). It auto-opens as your pup approaches (no pushing!) and locks tight 8 seconds later. One button adjusts the sensing range (20-28" or 35-43"). Patent pending. Custom Scheduling & Manual Control：Set access hours directly on the automatic sliding glass dog door—perfect for lazy mornings when you want to sleep in or short trips away. Collared pups come and go freely during your set times; after hours, the door ignores collars (so no midnight zoomies out the door!). Manual control lets you override anytime, just in case. Fits X-Large Pets (Up to 220 lbs)：Aiday automatic sliding glass dog door has an adjustable frame that fits heights from 76" To 80-11/16". The glass door opening measures 13.4" wide. Pro tip: For a perfect fit, measure from the top track to the inner bottom track of your aluminum sliding door frame before installation. Anti-Pinch Protection：Aiday Xlarge sliding glass dog door has a flap for smooth entry/exit, plus a built-in anti-pinch feature: if your pet lingers mid-passage, the door instantly stops and reverses to protect paws and tails. Plug-In Power with Easy Operation：Aiday automatic sliding glass dog door with sensor collar plugs directly into any outlet (extension cord included) for worry-free, continuous power. The extra-large display makes every setting instantly visible—no confusing menus, just straightforward operation you can trust every day.
