PetSafe Dog Door for Sliding Glass Door, 1-Piece, Medium to 40 lb, White

• Choose The Right Size: This Medium door is for cats and small-to-medium dogs up to 40 lb. The flap opening is 8 1/4 in W x 13 3/16 in H. Compare your pet's shoulder height and chest width to the flap, not weight alone. The step-over height is 1 3/4 in.
• Fits Your Sliding Door Track: Adjusts in height from 75 7/8 to 80 11/16 in and slides into your existing track, so there is no cutting into doors, walls or frames. Measure your door's height at the track before you order.
• Plan for Your Doorway Space: The panel is 11 1/2 in wide and sits in the track beside your human sliding door, so it takes 11 1/2 in out of the walk-through opening for people.
• Lock It and Control Access: The closing panel slides over the flap to keep your pet in or other animals out, and the included latch kit lets you lock your sliding glass door once the panel pet door is in place.
• Renter-Friendly, Weather-Ready: One assembled glass panel for temporary or permanent installation that you can take with you when you move. Weather-resistant aluminum frame, shatter-resistant tempered glass, glass sweep and a magnetic flap help keep drafts out.

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 Medium size in white is made for cats and small-to-medium dogs up to 40 lb, with a flap opening of 8 1/4 in W x 13 3/16 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 11 1/2 in wide panel sits in the track beside your human door, it takes 11 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).
