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.

OSO Barbell Collars is rated 4.7 out of 5 by 127.
Rated 1 out of 5 by from Too tight Too difficult to get on and off my Rogue Olympic barbell and it wouldn't even fit for my SS bar. I had to return it. There are better options out there.

Rated 5 out of 5 by from Best Collars I thought these were too small at first, turns out that they opened wider than I realized. They go on. They stay put. Quick and easy. Just make sure that your digits are clear when you go to remove them as the opening "snap" can sting if it gets you.

Rated 5 out of 5 by from Best collars out there Bought collars over a month ago. Once the are locked into place there is no wiggle

Rated 5 out of 5 by from Super tight No matter how many times you drop the barbell from power cleans or jerks, these clips isn’t moving.

Rated 5 out of 5 by from Holds the weights without any movement or worries I use this on my adjustable dumbbells, no more worried about weight falling in my head during snatches.

Rated 5 out of 5 by from Excellent Collars They hold the plates in place snug, and look good doing it I would buy again, but I like the cerakote rogue U.S.A. collars even better.

Rated 4 out of 5 by from Aggressive springs These collars would get a 5 star except the release springs are so tight that they snap open with heavy force. Not a big deal as long as your hands or fingers aren’t in the way. Took me a number of bruises to develop a safe and effective release technique.

Rated 5 out of 5 by from Exceeds all expectations I purchased these collars several years ago, because never a week goes by when I'm not looking around for a set of collars at the gym. I chose these specifically as they DO NOT look like the collars at commercial gyms ( wouldn't want to be accused of walking out the door with gym equipment ). A word of caution though, commercial gyms often have barbells built to a lesser standard than say, a Rogue barbell, and hence it can be difficult to clamp them, depending upon how badly out of tolerance the barbell sleeve(s) are manufactured. However, since the pandemic, I've converted strictly to workouts from home with a properly manufactured Rogue barbell!
