This cat door for window gives your cat a dedicated passageway while fitting window widths from 27" to 32" with a 5" adjustable range. Its aluminum alloy frame and clear glass panel are built for daily use, while the magnetic flap and brush-lined edge help provide smooth, quiet closing and a tighter seal. The 4-way locking system allows in-only, out-only, two-way access, or full lock mode for flexible control. Tool-free installation makes setup quick and convenient without drilling.
