Description

4″ Blue Rubber Wheel. Roller Bearing in the Wheel. 4″ Wheel shown in Photo. This K3A total lock caster is defined by their brake, which locks the swivel bearing and wheel at the same time. Plate Caster Model K3A is made using a stamped steel construction and is zinc plated. This plate caster uses a ⅜” diameter axle and the swivel caster raceway is held together by a ½” diameter rivet. This institutional plate caster is constructed with two ball bearings for enhanced swiveling and changing directions. There is a solid cover over the swivel raceways to shield them from dirt and dust. This plate caster performs best if you limit the load to no more than 1200 lbs on a set of 4 Model K3A casters.
