Barbell lockjaw collars are an essential gym accessory for weightlifting. Yanre Fitness makes versatile lockjaw collars that ensure safety by securing the weight plates in place.

Our barbell collars have a proprietary design consistent with Olympic bars, barbell bars, & dumbbell handles. 

Barbell lockjaw collars have a framework of aluminum alloy resin with pressure pads that are injection molded.

Our barbell & dumbbell lockjaw collars are highly durable & hard-wearing. They make weightlifting sessions at the gym safer & last a long time too.

Yanre Fitness lockjaw collars are well-suited to weight plates with urethane, rubber, or enamel coating. They can be put on & taken off with one hand, making them easy to use.

The single-action locking clamp allows fast removal of the lockjaw collars & quick weight plate changes. 

It ensures stability during high-intensity lifting sessions. The quick locking clamps are an asset during drop set lifting exercises in particular.

Yanre Fitness lockjaw collars have aluminum alloy interior plugs for a firmer hold on the barbell sleeve. The sleek exterior & the new handle design gives them a professional look. Our lockjaw collars are available in pairs & fit all standard Olympic bars.
