Installed this in our window so the cat can come and go without us playing doorman all day. The adjustable fit snugged right into the 27-inch opening, and switching the dial to in-only at night keeps him from wandering. Feels sturdier than the flimsy plastic flap we had before.

The 4-way lock is the feature I didn't know I needed — I keep it on in-only at night so my cat can't sneak back out. Fits my window snugly and the flap doesn't rattle in the wind.

The 4-way lock has been a lifesaver for keeping the cat in at night while letting her out during the day. Fits the window width well, though the frame flexes slightly when she pushes through. Overall solid for the price.
