Overview
A pet door built into an aluminum frame that fits into a sliding window opening between 32 and 36 inches wide, made from HD high transparency glass with a magnetic closing flap, sold under the HOMEPEDIA brand.
The listing emphasizes a 10 minute install, aimed at renters or anyone who does not want a wall cut, and the magnetic close flap is there to keep drafts out between uses. It is rated to a 25 pound weight capacity, so it is built for cats and small dogs rather than larger breeds.
- Fits 32 to 36 inch sliding windows
- 25 lb weight capacity
- Magnetic locking closure
- Aluminum frame, weatherproof design
Who it's for
Fits homes with sliding windows in the 32 to 36 inch range where cats or small dogs under 25 pounds need their own door without cutting into a wall. It will not work for larger dogs or for windows outside that width range.
