Our lock jaw design aluminum collars are a premium barbell collar that will keep your weight plates locked down and secure. Simply pull their levers fully open until you hear a 'click' and slide over your barbell. Lock firmly into place by sliding their levers in the opposite direction.
Rubberized inner linings are also included to help protect both the collars and barbell during repeated use. Sold in pairs, these collars are suitable for Olympic Barbells with a 50mm diameter.
