This Sandusky WCASTERSET4 caster set has two swivel casters and two swivel casters with pedal-style brakes, and is suitable for use with a wire shelving unit (not included). The wheels on each caster have a 4" diameter and are made of rubber for use on carpets and hard surfaces. The swivel mounts allow movement with a 360-degree change in direction. The pedal-style wheel brake on two of the casters help prevent them from rolling when the foot-operated lever is depressed. This set of casters has a 660 lb. load capacity when the weight is evenly distributed across all four casters.
