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 5 out of 5 by from Amazing Collars These collars are amazing, great build and superior workmanship. To the guys that complain that they snap when removing the bar all I can say is move your thumb out the way lol I literally use one finger they are great and easy to use.

Rated 5 out of 5 by from Usage: Opening/Closing I had these for a while now, over 4 months. Initially, when using I was not opening the clamp all the way and struggled to get them on/off. So, I stopped using them and by chance one day I opened them all the way not being afraid of breaking them and it allowed the extra room to easily slide on/off the bar. Do not make the same mistake and write negative reviews for human error. Use both hands when operating or you will experience some pain from the clamp snapping back.

Rated 4 out of 5 by from Husband loves these....but... I got these for my husband as a gift. Fits great on his straight bar - he absolutely loves them. However, they do not fit on his rogue hex bar which is a bit of a bummer. When I picked them out, I assumed that the collars would fit all rogue bars well- I guess that was my mistake. He says they’re great quality and believe they’ll last a long time.

Rated 5 out of 5 by from Work Great. I've had these for almost 2 years. They work great, never slip. Don't listen to the people saying they hurt. All you have to do is use 2 hands. Something under tension is obviously going to spring open. Buying a set for my fiance.

Rated 5 out of 5 by from Excellent clamp - my favorite I like these better than any others. I like the ease of clamping it down and how tight it holds against the bar collar.
