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.


  • Sold in Pairs
  • Made in the USA
  • Designed to be used on 50mm Olympic Bar Sleeves
  • 6061 Billet Aircraft Grade Aluminum
  • Black Rubberized interior lining to protect bar

*OSO Barbell Collars are designed to take a lot of abuse when clamped on a barbell. Aluminum will bend, however, so when they are not on a bar, avoid throwing, kicking, or stepping on the clamps (or any other means of abuse), as this will void your warranty.

Rogue OSO Barbell Collars is rated 4.2 out of 5 by 18.
Rated 1 out of 5 by from Broke on second use Broke literally the second time using it..... 80 dollars for 2 uses, shame to make whole thing out of metal than a tiny little clip made of cheap plastic...

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.

Rated 5 out of 5 by from OSO Barbell Collar I purchased the OSO barbell collar last month. It reliably keeps bumper plates locked in with no sliding issues - particularly, with heavy workouts such as cleans, jerks, squats, and bench press. Initially, I was concerned about lock mechanism due to prior reviews - but I’ve had no issues (make sure collar/lock is completely open before sliding onto bar).

Rated 5 out of 5 by from Best clips ever! I have been using these for a 3 weeks and they work great! I have not seen them move with 2 -#45 plates on the bar and dropping the clean. They open and close quickly and once you get used to it, they work great.

Rated 5 out of 5 by from Work Great I bought these over a year ago and have used several times a week - they've held up great. They weight .6 lbs so they pair perfectly with the typical 20kg bar to give you a true 45lbs - for the OCD of us. :) For those who gave lower reviews than 5 stars because the locking arm can snap/hurt your fingers when you open them... I'm not sure what to say - treat it like an IQ test?? ... see if you can flip it open with one finger while keeping your hand out of the way - we do now have opposable thumbs to separate us from the primates. :)

Rated 5 out of 5 by from Awesome collars I have no problem with them going on or taking off. If you pull the handle back to open it locks in place to make it easier to remove. Bumpers don't move once they are locked with these collars.
