The RetractAGate is easy to install. This customer used the Stair Banister Adapter Kit to create a flat surface for the mounting Brackets to attach to. This customer attached the adapter to her banister with included straps and home made spacers no screws involved! The other side was screwed in to a stud in her wall. She had to use spacers on the wall side to keep the mounting brackets plumb with eachother. With a little creativity and installation accessories, the RetractAGate will fit any space.
