Shepherd Replacement Chair Casters with Pivot Boss

The affordable replacement nylon chair casters feature a pivot boss (the upper barrel of the caster) that blends nicely into the base into the chair. Available in nylon (for carpet floors) or urethane tread wheels (for hardwood, tile, and other floors you want to protect) – these casters feature a common 7/16" grip ring stem that fits into most standard chair bases. Just pop the old ones out, measure the stem to ensure compatibility, and pop in these great replacement casters.
