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.
