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 37.
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!

Rated 5 out of 5 by from Works great These collars are super easy to use and will not slip once in place. The inside rubber protects the bar well. One note of caution, keep your hands back when releasing the lever. It will release with considerable force and smack your hands/fingers if they are in the way.

Rated 3 out of 5 by from Great quality, almost too a fault, however. Your weights won't budge with these, however, the locking clasp mechanism is a little over the top. For closing, it's easy and secure. For release, it's so tightly locked that when you open the clasp it pops back and hits your thumb/finger. It's not an easy flow on and off the bar, and for that I caution anyone getting these. I've had this thing hit my finger so many times when opening the clasp that I'm cautiously opening each time, which is an odd thing to do during a workout. Again great quality, almost too much.

Rated 5 out of 5 by from Collars If your tired of your plates creeping when being dropped from overhead based lifts then look no further then these collars.

Rated 5 out of 5 by from It just works I’ve tried other generic brand barbell collars and the generic ones don’t open up as easily due to a less precision plastic unlocking mechanism. Rogue OSO barbell collars just work better.

Rated 5 out of 5 by from Worth it These are worth the money. My gym never has working clamps or collars and I’m able to get my workouts in without spending 20 minutes walking around the gym looking. They slide on and off easily and plates not move once they’re on. Like the other reviewers said, make sure to open them all the way until the latch clicks or else it’s tough to slide on some bars.
