Service Caster #20 Series bolt hole swivel casters with 4 inch solid blue polyurethane wheel featuring Total Lock braking and zinc plated finish. This versatile caster is ideal for light and medium duty material handling, carts, equipment, and shop projects. Total Lock brake solidly locks both the swivel and wheel, providing an exceptionally sturdy base when engaged.
The polyurethane wheel performs well on most surfaces, and excels on hard surfaces like concrete, tile, and wood. Unlike black rubber wheels, no flat spots from sitting, and they will not mark or mar floor surfaces.
