The zinc plated finish provides durability under any condition, and the high temp phenolic wheels- quieter than comparable steel wheels- have a high resistance to impact damage, providing protection for floors in commercial and industrial settings.. Listing is for one (1) Service Caster Series #20 swivel caster with a 5" diameter by 1-1/4" wide high temperature phenolic wheel and a 1/2" threaded stem with total lock brake capable of supporting 300 lbs. Not only are they resistant to water, oil, and grease, but because they are non-metallic, these wheels are spark proof, keeping you safely moving forward.
