OSO Barbell Collars

OSO Barbell Collars are made in the USA 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.

OSO Barbell Collars is rated 4.8 out of 5 by 65.
Rated 4 out of 5 by from Worth the investment I bought these because my new box has Spring Collars, which I find nearly impossible to quickly change plates mid-workout. Or remove plates after a grippy metcon. The lock/unlock mechanism is a bit stiff in the beginning, but after a few weeks of use it's settled well. When locked, the grip is VERY tight. If the sleeve of your barbell has any imperfections you can catch tough friction when adding/removing the collar. That can slow you down. Super happy with these. I bought the pair in red and the color is bold- it's easy to spot from across the room and it prevents the collars from ending up with the rest of the community gear. Solid, high quality.

Rated 5 out of 5 by from Great collars Bought these a few weeks ago, they do exactly what they’re supposed to. The complaints about the collars being difficult to fit might be due to not opening the collars all the way, they lock in both directions. They fit similarly to regular plates when open, so if you grab it at an angle it won’t be easy to pull off. As far as catching your fingers goes, sure, you could, anything is possible, but you could also hold the lever as you operate it and don’t put your fingers on the other side. Very well made collars, make the gym’s acrylic collars look and feel like toys.

Rated 5 out of 5 by from My daughter loves them! Had to give them 5 stars because my daughter loves them....I wish the blue was the same navy blue as the bar I just bought her ☹️ Even though she doesn’t seem to mind

Rated 5 out of 5 by from Some of the best collars you can get I have had these for 3 months now and love them. There is a little learning curve so you don't smack yourself with the handle when it springs open and make sure to open them all the way when attaching or removing them. I have not had one slip yet. The annodizing is holding up well after being tossed into my gym bag at the end of the day.

Rated 5 out of 5 by from LOVE Them! Purchased a few weeks ago. Love them! Amazing grip. Plates do not move after many dropping of the bar during Oly lifts.

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!)
