Rogue OSO Barbell Collars

This is the exclusive, Rogue-branded version of the OSO Barbell Collar—an innovative, aircraft-grade aluminum clamp designed are manufactured in Columbus, Ohio.

Sold in pairs and equipped with a rubberized interior lining to protect the bar, OSO Collars deliver a secure, stable hold through repeated, high-impact drops, and allow easy adjustments or removal with a simple lever and lock/unlock mechanism. It’s the OSOs unique look, though, that generates the most attention. With this design, that means an industrial gear-style shape in gunmetal gray with the Rogue logo down the side.

Rogue OSO Barbell Collars is rated 4.7 out of 5 by 49.
Rated 5 out of 5 by from Work great! So far, I just use them for powerlifting and they grip just perfectly. Open them all the way to slide on and off easily as others have suggested. They have a tendency to snap open on release so learn to keep your fingers out of harms way when you flick them open. Over time, the cam action has broken in and has become much smoother to operate.

Rated 5 out of 5 by from They're snug! I've had these about 6 weeks and love them. They hold the weights in place for Olympics lifts (dropping the barbell) very well. They don't wiggle their way loose like the squeeze clips. I'm a fan!

Rated 5 out of 5 by from Great collars I bought these a few months ago and they are awesome. Easy to put on and take off and holding any plates in place.

Rated 5 out of 5 by from Good quality I've had this for about a month and I love it. Just make sure you keep your thumb clear when locking/unlocking it- my partner caught her thumb a couple of times. Overall it does what I want which is keep the plates in place when I'm doing barbell cycling. A little expensive compared to others but the Rogue brand is so durable and the customer care is also on point so I believe it's worth it.

Rated 4 out of 5 by from Good collars Splurged for some fancier collars. These work great, but needed to be "broken in" a little with consistent use so they were less energetic/forceful when released. At least I know the plates aren't falling off the bar in the middle of a workout!

Rated 5 out of 5 by from Work of Art Going to get another set of these OSO Collars when the Loadable Dumbbells become available. They have a very precise fit on the barbell. I use the OSO collars for all my workouts.

Rated 5 out of 5 by from Great Pair of Collars! I use these with my Rogue training bar and echo bumpers. They are amazing! I read reviews where people were having difficulty putting them on or removing them. I was concerned that I was going to have similar issues. That was not the case! These collars slide on with ease. The locking mechanism is very easy to use. I did not have any problems with it wanting to rip my fingers off. Best of all, the rubberized interior ensures my bar stays as pristine as can be.

Rated 3 out of 5 by from Not a fan I may just be use to the gym collars, but these are not only much harder to take off, they also can painfully snap on you if you try to take them off the barbel with one hand. Snapped on my fellow crossfitters a few times when they first used them. Will up the score when I do some heavy olympic lifts if the plates dont move.
