Overview
This is a flap style pet door for interior installation, sized for a 7.1 by 7.3 inch flap opening and finished in white. It mounts into wooden or metal doors, or into a window panel, and suits cats and small dogs rather than full sized dogs.
The main feature is a 4 way lock that switches the flap between in only, out only, both ways, and fully locked, so one door handles daytime access and nighttime security without extra hardware. Namsan markets it as weatherproof for exterior use, though the white interior finish points to indoor doors as the main fit.
- 7.1 x 7.3 inch flap opening
- 4 way locking flap
- White finish for interior doors
- Weatherproof rated for exterior use
Who it's for
Cat owners who want a pet to move between rooms or in and out of the house without a door left propped open. Also workable for small dogs that fit the flap opening size.
Pros and cons
- 4 way lock covers entry, exit, and full lockout
- Installs in wood, metal, or window panels
- Sized for cats and small dogs
- No listed door thickness range to confirm fit
- Opening too small for medium or large dogs
Performance notes
The 4 way lock is the functional core: turning it restricts the flap to entry, exit, both, or full lockout, letting an owner control access at set times of day. No thickness range is listed for the doors it fits, so measure before buying.
