Made to fit a wide range of both square and round tube legs, adapting to tube leg inside diameter. Swivel fork, raceway bearing and wheel roller bearings are stainless, as well as the axle and spanner bushing. Stainless steel is used to protect metal caster parts from corrosion caused by cleaning agents, steam and steam cleaning, caustic solutions, and other rust causing agents.
Easy to Install Expanding Adapter Stem Casters
Tighten the topmost ring on the expanding caster adapter stem before insertion to compress rubber until it fits snugly into the tube. The expanded stem can be inserted into round or square tubing. It may be necessary to further tighten the nut under the swivel with a wrench until adequately secured.
