Overview
A medium-size flap pet door with a 4-way lock, sized for a 5.98 x 5.7 inch flap opening and built for cats, small dogs and medium dogs. The plastic frame installs into interior or exterior doors, windows or walls and is listed as weatherproof.
The 4-way lock lets owners set the flap to locked, in-only, out-only or free swing, which is useful for controlling access rather than leaving pets with one fixed setting. Listed compatible door thickness is about 2.16 inches, so it is worth measuring the door before buying since a mount built for one thickness will not seat properly on a much thicker or thinner door.
- Medium flap, 5.98 x 5.7 inch opening
- 4-way lock: locked, in, out or free
- Weatherproof for interior or exterior use
- Fits doors, windows or walls
Who it's for
Works for owners of cats or small to medium dogs who want controllable, lockable access through a door, window or wall opening. Owners with a door notably thicker or thinner than roughly 2.16 inches should confirm fit before installing, since the listed compatible thickness is narrow.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4-way lock controls access direction
- Weatherproof for exterior door installation
- Sized for cats and small to medium dogs
- Narrow listed compatible door thickness
- Plastic frame rather than metal
Performance notes
The 4-way lock mechanism is the core function, letting the flap be set fully locked, one-way in, one-way out or free swinging depending on when a pet needs access. Weatherproofing is aimed at exterior installations where the flap is exposed to outdoor conditions, and the plastic frame and flap size the opening for cats and smaller dog breeds.
