PetSafe Dog Door for Sliding Glass Door, 1-Piece, Large to 100 lb, White

The PetSafe Sliding Glass Pet Door, 1-Piece is a no-cut dog and cat door insert that slides into the existing track of a sliding glass door. This Large size in white is made for medium-to-large dogs up to 100 lb, with a flap opening of 10 1/4 in W x 16 3/8 in H. It adjusts in height from 75 7/8 to 80 11/16 in and arrives as one assembled glass panel, so there are no two sections to connect. How to choose: measure your sliding door's height at the track, then compare your pet's shoulder height and chest width to the flap opening, not weight alone. Because the 13 1/2 in wide panel sits in the track beside your human door, it takes 13 1/2 in out of the walk-through opening for people. Taller sliding doors (91 7/16 to 96 in) need the 96 in version, available in Medium, Large and Large-Tall. Sizes in the 1-Piece line (pet weight, flap opening, step-over, panel width): Small (15 lb, 5 1/4 x 8 3/16 in, 1 3/4 in, 8 1/2 in), Medium (40 lb, 8 1/4 x 13 3/16 in, 1 3/4 in, 11 1/2 in), Large (100 lb, 10 1/4 x 16 3/8 in, 4 1/4 in, 13 1/2 in), Large-Tall (130 lb, same flap as Large, 8 1/4 in, 13 1/2 in) and XL (220 lb, 13 11/16 x 23 3/4 in, 4 1/4 in, 16 1/2 in). What you get: weather-resistant aluminum frame, shatter-resistant tempered glass, a tinted flexible flap with magnetic closure, a slide-in closing panel to keep your pet in or other animals out, and a latch kit to lock your sliding door. The box includes the closing panel, T-brackets, glass sweep, screws, latch assembly and manual. 1-Piece vs. 2-Piece: the 1-Piece glass panel is a single piece with no assembly, while the 2-Piece has two connecting panels that come apart for easier storage. For homes with very hot or cold weather, see the Extreme Weather model with dual-paned glass and three insulated flaps. Install it temporarily or permanently, and take it with you when you move.
