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 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!

Rated 5 out of 5 by from Great clips Love these clips, they do not loosen, just beware the spring load will get you if you aren’t careful, but well worth it!!

Rated 5 out of 5 by from Worth every penny Not only do they feel sturdy and look nice, they work amazingly. It's a bit rough to get them on an actual barbell, but I mainly use them for my makeshift dunbells

Rated 5 out of 5 by from Great collars! I really like the collars. When I first put them on the bar, it was a little difficult getting them on and off my Rogue bar and I wondered if this was going to be a problem. However, the the pliable material compressed slightly and now the collars go on and come off easily but still provide a snug fit. Perfect!

Rated 5 out of 5 by from Collars Great idea with the bright color's--my vision is not the best and I can locate them easier.

Rated 3 out of 5 by from Green is not the color pictured. I received the green one today and the green is darker in color. What is listed looks a bit neon. The blue set we own is pretty accurate compared to the main photo in the listing. Functionality and quality is as expected from Rogue. Colors on the other hand....
