OSO Barbell Collars

OSO Barbell Collars are made in the USA from the same type of 6061 aluminum alloy used in aircraft construction. The OSO Barbell Collars deliver on functionality, too--creating a secure hold on the bar through repeated, high-impact drops, and allowing easy adjustments or removal with a simple lever and lock/unlock mechanism.

All that being said, the first thing a lot of lifters talk about with the OSO Barbell Collars is how they look. Shaped like an industrial gear, the collars’ old school design is paired with some great color options.

For Oly lifters, CrossFitters, or any athlete looking for an upgrade from basic spring collars, OSO Barbell Collars are a nice option.

Rated 5 out of 5 by from Great quality and strong hold So much better than polymer collars. Solid hold that doesn't move after repeated overhead drops. Positive lock both open and closed. (Some people reporting that they are hard to slide on or off when open may not realize that they actually lock 'open' if you push the lever the opposite direction, which is a great feature too!)

Rated 5 out of 5 by from Excellent Collars They won’t move once placed on the bar and will make your workout go smooth and a bit faster. You won’t have to adjust them not even once. I CrossFit BTW

Rated 4 out of 5 by from Very Secure Clamps I bought these clamps for my works gym and have had all positive feedback from our members. The clamps are very secure when locked on to any bar. The only reason I didn't give them 5 stars is that they are a bit on the expensive end. The bright colors help them to stand out when you're looking for them in the gym. I think the aluminum construction will fare better in the long run than the cheaper plastic alternatives.

Rated 5 out of 5 by from I love them I read some reviews which made me skeptical. I liked the green ones so I figured I'd give them a go. The first week or so they didn't go on smoothly however after about a month I don't have any trouble. I love them and the green ones are nice

Rated 5 out of 5 by from A Must Have Every barbell should have these, solid grip when locked in, ease of use when slipping on/off making changing plates a breeze, very little slippage when dropped multiple times during CF WODs, but most importantly, adds a little color to my garage gym! I now have 3 pairs to comp my bars.
