Service Caster #20 Series stainless steel swivel casters with a blue polyurethane wheel. Featuring stainless steel components, these washable casters are ideal for work tables, shop projects, and any equipment with round or square tube legs.

polyurethane wheel performs well on most surfaces, and excels on hard
surfaces like concrete, tile, and wood. They will not mark or mar floor
surfaces.

diameter of 1-5/8". Tighten topmost ring to compress rubber until it
fits snugly into the tube. If necessary, further tighten with a wrench
using the nut under the swivel until adequately secured.
