3 dog gates (South Novato (Sunset Parkway))

The wide one is currently set for 52-1/2" W but the center piece can be unscrewed to make it wider; it's 29" H. It has to be screw-mounted to the opening.

The medium one is a pressure mount that fits 30" doorways; it's 30" H. It opens by pressing a button on either side, but one side no longer works.

There is also a small gate, also pressure mounted, which fits a 30" doorway; it's 18" H.
