Service Caster #20 Series swivel casters with 4 inch 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.
Wheels roll smoothly with integrated ball bearing design. The
polyurethane wheel performs well on most surfaces, and excels on hard
surfaces like concrete, tile, and wood. Unlike black rubber wheels, they
will not mark or mar floor surfaces.
