Service Caster #20 Series rigid casters with 4 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.
