Overview
A full-glass, aluminum-framed cat door that slides into a window opening 22 to 28.5 inches wide, with magnetic closure and four locking modes.
Marketed for a one-minute install, this fits a narrower window range than some competing cat doors, sitting between 22 and 28.5 inches rather than wider openings. The four locking modes let an owner control the flap, such as locking it shut or open, though the spec sheet doesn't itemize what each mode does.
- Fits 22-28.5 inch window openings
- Four locking modes
- HD glass panel with aluminum frame
- Magnetic closure
Who it's for
Owners with a narrower window opening, 22 to 28.5 inches, who want a glass insert door with adjustable locking control for cats. Not for wider windows or households wanting a solid, non-glass panel.
Strengths and trade-offs
Drawn from this product's published specifications.
- Four locking modes for flap control
- Marketed one-minute install
- Narrower fit range, 22-28.5 inches, than some competing doors
- Glass panel construction
Performance notes
The sliding aluminum frame fits into the window track and adjusts across its stated width range, while the magnetic closure seals the glass flap shut when not in use. Four locking modes give more control over when the flap can be used than a simple open or shut design.
