Service Caster #20 Series swivel casters with 3-1/2 inch phenolic wheel. Featuring a zinc plated finish, these casters are ideal for light and medium duty material handling, carts, equipment, and shop projects.
Phenolic wheels have a high resistance to impact damage while providing protection for floors in commercial and industrial settings. These easy rolling wheels are quieter than comparable steel wheels. Phenolic resin wheels feature a resistance to water, oil, and grease. Being non-metallic, these resin wheels are also spark proof.
