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.

Rated 4 out of 5 by from Nice collars, but careful or they’ll bite! Solid collars. Looks cool, feels a bit kore premium than standard plastic collars, but they both keep bumpers in place. Nice positive click on locking, but when opened they snap open very quickly and will whack your knuckles if you’re not careful. Only had mine a month or so, maybe it’ll get better with time as some other reviews have stated.

Rated 3 out of 5 by from They are ok They are ok collars, the aluminum collars are way better than these but weren't available at the time. If you can wait until they are in stock get the USA aluminum ones.

Rated 4 out of 5 by from Mostly Secure These collars def do a better job at holding its place and keeping the plates against the end of the sleeve, but they do move a little bit (especially when dropping the bar from overhead).

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!
