Sockets suit spaces that switch between a queue and an open floor: a lobby that hosts events, an entry that opens wide on busy days, a service area that clears for cleaning equipment. The post seats in the socket, stands square, and lifts straight out when the line comes down. Choose the full floor socket with its cover cap, or the low-profile pin socket where you want the smallest opening in the floor. Either way the post above is a standard Beltrac 3000: one-piece extruded aluminum, 4-way dovetail grooves that take signs, panels, and NeXtrac fixtures, and a belt that retracts under a slow, controlled brake. Built in the USA, backed by a 5-year post warranty.
