Overview
A small adjustable plastic dog and cat door with a 4-way lock, sized for a 7.5 x 7.4 x 2.24 inch opening. It ships in white with the screws needed for mounting included.
The 4-way lock is the notable feature here, letting the door be set to fully open, fully locked, in-only or out-only, more control than a basic flap. It's the small size, meant for smaller dogs and cats rather than medium or large dogs.
- 7.5 x 7.4 x 2.24 inch opening
- 4-way adjustable lock
- White plastic construction
- Screws included for installation
Who it's for
Owners of small dogs or cats who want an installed door with adjustable locking rather than a fixed flap. Not sized for medium or large dog breeds given the small opening dimensions.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4-way lock for open, closed, in-only or out-only settings
- Mounting screws included
- Sized for small dogs and cats
- Opening is small, not suited to medium or large dogs
- Plastic construction, no stated weatherproofing
Performance notes
The 4-way lock lets the panel be set open, closed, or one-way in either direction, the main functional advantage over a simple flap door. Being plastic keeps it light for installation but it is not framed as a heavy-duty or weatherproof unit in the listing.
