3" Polyolefin Expandable Caster- 3PEC250
Our 3" Polyolefin Expandable Caster inserts directly into the tube end. With the assistance of a standard size wrench, the rubber collar expands to create a tight fit. Use on 5S boards or workstations. 250 lb. weight limit per caster.
Turn the top jam nut and snug on the rubber spacer. Place the caster into a tube. If loose in the tube, tighten the jam nut until the rubber touches the tube sides. When inserted, twist the large lock ring until the rubber locks in the tube. See fig. 1
