Service Caster #20 Series 3/4 inch expanding stem swivel casters with a 3 inch polyurethane wheel and Total Lock brake. Featuring a zinc plated finish, these casters are
ideal for work tables, shop projects, and any equipment with round or
square tube legs. Total lock brake system locks both swivel and wheel when engaged.
Wheels roll smoothly with integrated ball bearing design. The
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 3/4". 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.
