Lock It. Lift It. Trust It.

The Lock-Jaw Hex 30mm Barbell Collar is the last collar you'll ever need to buy. Built from solid nylon resin with injection-molded pressure pads — engineered to be nearly unbreakable through the toughest training environments and the heaviest drops.

Patented Single-Action Cam Lock — On and Off in Seconds

Clamp it on, flip the latch, and it's locked. Release it just as fast. No threading, no spinning, no fumbling between sets.

Nearly Unbreakable Construction

Solid nylon resin frame and injection-molded pressure pads absorb impact and resist cracking — won't split, warp, or lose clamping force over time.

Slim, Light, and Secure

Slim and lightweight — taking up minimal sleeve space so you can load more plates. Sits flush against the plates and stays put, no matter how hard you train.

Fits 30mm Sleeve Bars

Designed specifically for 30mm sleeve bars, including studio pump sets and group fitness barbells. Available in grey and black.
