Overview
This is a wall-mounted pet door, not a gate, built with a steel frame and a telescoping tunnel that adjusts to wall thickness between 4.75 and 7.25 inches. The small size is rated for cats up to 10 lbs with a listed weight capacity of 12 lbs.
Because it's a through-wall install with a telescoping tunnel, the tunnel length has to match the actual wall thickness at the install site rather than just the door opening, so the wall should be measured before ordering. The double silicone flaps and magnetic closure are meant to cut drafts when the door isn't in use.
- Telescoping tunnel, 4.75 to 7.25 inch wall thickness
- 12 lb weight capacity
- Steel frame, white finish
- Magnetic, lockable double-flap closure
Who it's for
Fits owners cutting a wall opening for a small cat or a comparably sized small dog who want a locking, telescoping through-wall install rather than a door-mounted flap. Not right for anyone wanting a simple in-door flap, or for pets over the 12 lb capacity.
Strengths and trade-offs
Drawn from this product's published specifications.
- Telescoping tunnel fits walls from 4.75 to 7.25 inches thick
- Lockable for times the pet should stay in or out
- Steel frame with double silicone flaps for draft resistance
- Requires cutting a wall opening rather than a simple door install
- Capped at 12 lbs, so not for larger cats or dogs
Performance notes
The telescoping tunnel is what lets a single unit fit a range of wall thicknesses, sliding to the correct depth during installation. Double silicone flaps and a magnetic closure aim to seal the tunnel against drafts when the pet isn't passing through, and a separate lock lets owners close the door off entirely.
