Rite-Hite says its Dok-Guardian safety barrier provides a 4-ft. high visual barrier across the door, preventing employees and material handling equipment from falling off vacant loading docks. It is available in a heavy-duty model (SB-5000) and a light-duty model (SB-2500). The SB-5000 guards are made from 1⁄4-in. steel, while the SB-2500 guards are made from 3/16-in. steel.
