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 4 out of 5 by from Great Collars. Not so happy about the color Collars are great. Built well and easy to use. Was disappointed with the green. It does not look like the picture at all, more of a yellow green. I probably would have bought a different color if I knew that.

Rated 4 out of 5 by from Sturdy, Tough, Great Color These collars have that Rogue durability I love. They are rugged, sturdy, and I love the green color. I gave it four stars instead of five because I find them hard to get on. That said, I struggle with hand problems, so many people may not have difficulty at all.

Rated 5 out of 5 by from Great Collars I have bought different collars and these by far are the best.

Rated 5 out of 5 by from Great collars! If you’re on the fence, go for it! I can finally drop my bar after a heavy snatch and my weights on the bar don’t shift! I’ve gone through so many pairs of cheap collars. I’m so glad I made this purchase!

Rated 5 out of 5 by from Awesome! I bought the collars over a month ago and I love them and they’ve held up well, still great color!

Rated 5 out of 5 by from Easy to use, tight hold, good design Bought these weeks ago out of the Boneyard and they work great. They're easy to open and close the lever and they hold our plates on very well. They are easy to open one-handed even if your hands are sweaty. They work by pulling the aluminum around the whole bar by the lever pulling the open ends together, and the plastic lever locks well with good leverage.

Rated 5 out of 5 by from Happy customer I bought the purple collars for my husband to replace an older pair he had. He really likes them and was happy with the color.
