A latch that secures a closure member includes a bolt and a support member, with the support member attaching the bolt to a part, which could be a door frame. The support member is configured with head and shank portions, so that when the support member is tightened to the part, the bolt is free to rotate and slide about the shank. The bolt is held captive on the support member by a shoulder of the head, and a longitudinal slot in the bolt allows the bolt to rotate and slide about the shank. The bolt has a second slot with parallel sides that engage parallel flat surfaces of the support member head, thereby suspending the bolt in a horizontal closure locking position to allow unobstructed opening or closing of the closure member.
