We bought this extra wide gate for the top of the stairs on our sundeck because it was the only one we could find that was wide enough.  It does work just fine and was very easy to install.  We are using it at the fullest extension and I am a bit ocncerned that as the babies (yes, twins) grow they might be able to push the centre it off the edge of the top stair, but at this point, it is certainly doing the job just fine.  I would recommend this if you need a gate for this width.
