Shaxon"s Hinged 4U wall bracket (H7.00" x W19" x D6") is designed as an economical way to mount either (1) 4U 19" panel or (2) 2U 19" panels to a wall or backboard. Hinge brackets can replace relay racks or other expensive wire management products where space is limited and the rack space requirements permit it. Shaxon hinged brackets are finished with a durable black powder coat.
