Two extending metal safety/stair gates, will fit gap 63cm to 102cm. We had one at the top and bottom of our stairs, but they will also attach in a doorway. These are particularly suited for stairs as they open completely, unlike pressure gates where you walk through a narrower gate in the middle and have to avoid stepping/catching your foot on the floor bar that runs across the stair tread, not ideal if carrying a baby! Comes complete with all the fitting brackets etc. and fitting/user instructions. ;
