Unique, no-screws solution for installing any safety gate to different shaped stair posts, or across 2 spindles. Simply clamp the Fred Stairpost Kit into position to provide a strong and sturdy wooden surface against which your stair gate can be attached. Held in place with straps, you’ll not damage woodwork, and it’s an easy solution for metal staircases. Made from bite-proof, lick-safe materials for extra peace of mind. Works with both pressure and screw fit gates up to 86cm tall. Stairposts can be round or square (up to 10cm diameter), and if fitting across 2 spindles, they should be no more than 20cm apart (from outside edge to outside edge). Wipe clean with a damp cloth.
