OSO Barbell Collars

OSO Barbell Collars are manufactured in Columbus, Ohio from the same type of 6061 Billet Aircraft Grade 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 bright color options: blue, green, orange, pink, purple, red, gold and gun metal.

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 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 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 1 out of 5 by from Deficient collar I ordered the OSO Pro Gun Metal collars. When they arrived, one of the collars came without a rubber lining (making to collar useless). I've made several attempts through email, live chat, and phone to reach out and request either a refund or replacement, but haven't heard back. I also see that they are no longer offering the OSO Pro collars, except as a boneyard. Have experienced pretty terrible service all the way around from Rogue in the last 2 months.

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.
