These casters come in 12 twin-wheel models, made for a number of applications including medical equipment, hospital beds and stretchers, appliances, furniture and retail displays. All casters in a set can be locked simultaneously, using a fully-enclosed, positive mechanical brake and locking system. The casters are made out of lightweight, pressure-diecast aluminum shells, with standard gray polyurethane and gray rubber wheels. They are made to reduce swiveling and pushing effort, using roller bearing and twin-wheel design for low rolling resistance and smooth tracking. With the total lock mechanical brake in the "off" position, the wheels swivel and rotate freely, and swiveling and rotation are prevented in the "on" position. Load capacities range from 198 to 330 lbs. Available overall wheel heights are 138 mm for 5-inch wheel diameters, and 164 mm for 6-inch wheel diameters. The swivel radii are 106 mm for 5-inch casters and 131 mm for 6-inch casters.
