Rogue OSO Barbell Collars

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

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 43.
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.

Rated 5 out of 5 by from Holdin On Tight Nice appearance,easy to use.lever is a worry,I’ll see how long it lasts.

Rated 4 out of 5 by from Unlocked, not open The lever has three positions: locked, unlocked, and open. The collars won't fit over the bar unless the lever is in the open position (pass 90 degrees). I didn't know this the first time I tried to use them and was upset at the apparent fit problem. FYI.

Rated 5 out of 5 by from Great collars! No complaints. They slide perfectly on the bar and the bumper plates don't move. Love them!
