Overview
This is PetSafe's Never Rust Wall Entry Pet Door in the large size, a telescoping-frame unit that mounts through an exterior wall rather than a door panel. It fits wall thickness from 4.75 to 7.25 inches and holds pets up to 100 pounds.
The telescoping frame adjusts to the wall's actual thickness at install time, and PetSafe positions the flap as more insulating than a metal door, which matters for exterior installs in hot or cold climates. It ships with drywall screws, toggle bolts and a template for a full DIY install. Despite the category label attached to this listing, it is a wall-mounted door, not a gate.
- 100 lb weight capacity
- 4.75 to 7.25 inch wall range
- Flap closure, plastic frame
- 1 year limited warranty
Who it's for
Suited to owners of large dogs up to 100 pounds who want a dedicated wall opening rather than cutting into an existing door. Best for exterior walls that fall inside the 4.75 to 7.25 inch telescoping range; anything outside it will not fit.
