The CRL Knob Latch assists in latching and centering a door in either glass-to-wall or glass-to-glass installations. It is very helpful in job conditions where a slightly out of alignment situation exists, and positive closure to zero degrees is needed. An internal three-point ball bearing index mechanism keeps the Knob Latch from "free-spinning". The Knob Latch is operational from both sides of the door. It includes a Tapered Strike (180 Degree Model only) for glass-to-wall installations, and a J-Hook for glass-to-glass installations. J-Hook is adhered using our water clear UV70330 Ultraviolet Adhesive.
