We bought this to fit our patio doors with them being so narrow; we were lucky as we could still open and close the door with the gate in place. It was a little irritating having to prop it open when we wanted to use it without the kids around, but only a small grievance. The problem came when I wanted to remove it; once it is tightened into place it is extremely hard to get it back off again, as you can't just unscrew it, the bits you turn to tighten the gate lock into place with each twist. I ended up having to literally put my full weight onto it and lean backwards, while my hubby shoved at it from the other side, so that it popped out of the doorframe. I dread to think what damage that might do to wooden or plaster surfaces! So be warned; once in place they stay in place! Does mean that the kids will never be able to get them to come off though :)
