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 2 out of 5 by from Hard to get off without pinching or smashing I bought these clips thinking they would be better then the clips used at the gym. These clips stay in place well but are very hard to get off. They pinch and bruise my hand each time I take them off because they snap back so fast. Very disappointed. Wondering if the other clips do the same thing.

Rated 5 out of 5 by from Nice collars Picked up a pair of these collars in the boneyard- they're super nice, lock up tight, and look great. Much heavier duty than my spring collars. Only saw a couple of knicks in the finish, and they work just fine.

Rated 5 out of 5 by from Superb Lightweight and really lock on. Dropping the bar from overhead and no slip. Never have to reset. Real time saver. Time will tell if they stay this way. Here's hoping

Rated 1 out of 5 by from Plastic lever snapped after second use These seemed great in theory but the lever on one collar snapped after the second use. Using plastic for these levers seems like a shockingly poor design decision from an otherwise solid company like Rogue. I haven’t tested out their other collars but I would be cautious before purchasing these ones specifically.

Rated 5 out of 5 by from Easy on the hands I bought these to use at my gym because the majority of collars there are the clamp type that require a lot of hand strength...tough at times on my arthritic hands. These are so much easier.
