The Gatemaster Superlock Gapless Keep is a slimline device that fits between the gate and the post, acting as both a gate stop and a strike for the lock. This keep works with any of the Gatemaster Superlock locks that work on a latch. The narrow profile blends in well with the gate thereby improving on the gate's appearance. Furthermore, it has a stainless steel strike plate with a black powder-coated stop, incorporating 2 rubber bump stops to ensure the gate makes minimal noise when shutting. The keep is designed to fit to a box section gate post, by simply drilling 2 15mm holes and screwing on using the innovative expanding fasteners supplied.
