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.

Rated 5 out of 5 by from GREAT!!! I bought these almost a month ago and are fantastic to just keep in my gym bag for "emergencies" (e.g. when the clamps disappear at the gym, you have an extra pair and a color that stands out.

Rated 5 out of 5 by from I don't know how to workout now I feel like I'm a great person to review these collars as I'm not very fit and have to drop the barbell 3 times as much as any other athlete during a workout. If anyone knows about dropping weights, I'm the guy. Rich Froning's review? Although highly respected, worthless. What does he know? He only drops a barbell once in a workout. Anyway, these collars keep my plates secured tightly to the barbell even in the most dynamic situations, like bouncing across the gym floor causing everyone within a 10 foot radius to dodge it between their reps. The only problem is now I'm not able to catch my breath while re-securing my weights and adjusting my collars. That was my "go-to". Now I'll have to do something else to buy me time, like fake tie my shoe or walk outside to make sure I didn't lock my keys in my car. I love these collars but they have totally messed up my approach to workouts.

Rated 5 out of 5 by from Fantastic I bought these clips for Christmas gifts last year. They are absolutely worth the money. Highly recommend the case to keep them in. Buying more this year for gifts. Sadly to find out that you can’t buy the cases to keep them in any more

Rated 5 out of 5 by from Solid performer! Tight fit on bar! I have used these collars at the gym and decided to get some for myself to use when the others were being used. Excellent light weight collar and good tight fit on the bar.

Rated 4 out of 5 by from Works well but... Works very well, however, I ordered the blue and it’s not even close to the color shown which is disappointing. Also would be nice if the handle was aluminum instead of plastic.

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.
