Description
Model 30 Swivel Casters that use the Polyurethane on Iron – Slight Crown Tread Wheel are an upgrade from the model G15 swivel caster. They feature substantially larger swivels, wider wheels, and wheel bearings. The swivel casters are designed with lubricated fittings for all adjustable parts as well as plated with zinc for rust resistance. Another add on option is to include a face contact wheel brake to latch the wheels and a manually operated swivel lock to convert the swivel caster into a “rigid caster” when the need arises.
