* To be used for Axle Bars, Farmers Walk Handles, and Multi-Grip Bars ONLY

OSO Barbell Clamps were born out of a frustration for the alternative. Who hasn’t either had weights move during a heavy lifting day or struggled to get spring collars on/off quickly when seconds count. OSO Barbell set out to make a better collar.

With input from all over the CrossFit world, these collars were built to be functional by not only keeping the weights in place, but also look good while doing it.

OSO Barbell Collars are made in the USA from 6061 billet aircraft grade aluminum, these collars are made to take a beating. 

Affectionately referred to as the Tortuga, this collar is a perfect fit for axel bars. This unique design flips the script on the OSO collars you have come to know and love and in a cool color that won't be confused with other collars in the gym.
