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.

Rated 3 out of 5 by from Do not buy these for adjustable dumbbells While they hold great, you should not get these with the loadable dumbbells - they protrude quite far and can really bruise your thigh if you try and rest the dumbbell on it. Get the USA aluminum ones instead.

Rated 4 out of 5 by from Thought they would hold better I like these collars. They are better than all my other generic collars, but I thought they would hold my plates in place fully when dropping the weights. I have Rogue HG and Mil Spec plates as well so not an off brand plate. I watched and read reviews and purchased these because it’s what they use at the games. Maybe I had extremely high hopes that nothing would budge and that’s why I’m disappointed. Still a great product and they definitely still do the job.

Rated 4 out of 5 by from Great Collar My only complaint is that the lever smacks the f out of your hand when you flick it open. Definitely wish the lever was longer so that it wouldn't take so much force to lock the collar. The weights definitely don't move at all though. I think I'd prefer the weights wiggling just a little bit if it meant the collars were easier to use. Am trying to break them in but still sometimes just use my rubber collars.

Rated 4 out of 5 by from Strong but difficult I won't lie, I bought these because they were on the more expensive side. They definitely have great hold to the bar, just a bit difficult to unlatch and get on/off the bar. I don't do allot of high movement exercises so I probably didn't need this type of collar.

Rated 5 out of 5 by from Great Features! Best collars I've ever used! They hold incredible amounts of weight tightly in place and don't move an inch.
