Replacement UHMW plastic insert for one Factory Weights Flip-Down Safety Bar. UHMW is the hard-wearing plastic that protects your barbell's knurling when you rack the bar or miss a lift; once it's grooved or cracked, swap the plastic rather than replacing the whole safety.

Sold singly, so order two for a pair of safeties. Fasten with our UHMW Plastic Bolts, sold separately.
