PetSafe Sliding Glass Pet Door: Large, 100 lb, 75 7/8–80 11/16 in

Why it matters

The one-piece panel fits into your sliding door track without cutting, adjusting from 75 7/8 to 80 11/16 in tall. The tinted, flexible flap opens 10 1/4 x 16 3/8 in for pets up to 100 lb and seals with magnets, and a slide-in panel closes it. Weather stripping and a glass sweep are included.

Limitations to weigh

Measure your dog's shoulder height and widest point; the flap top should sit at least an inch or two above the shoulder, and the step-over should be low enough for seniors and short legs.
Any flap big enough for your dog can let in wildlife, other animals and, rarely, people; lock the closing panel at night and when you are away.
Patio inserts narrow the sliding door opening; add a security bar or lock so the slider can't be opened from outside.
