OSO Magnetic Rogue Barbell Collars

The exclusive Rogue OSO Barbell Collar is now available with (4) built-in, high-strength magnets, allowing athletes to simply stick the collars directly to the rack in-between uses. It’s an easy solution to an age-old collar storage problem, and offers convenient arm’s reach access to the OSOs when you next need them.

Like the standard Rogue OSO Collars, these magnetic collars are machined in the Rogue factory from aircraft-grade aluminum with a gun metal gray anodized finish and industrial, gear-style design. Compatible with any standard 50mm Olympic barbell sleeve, each Rogue OSO MAG Collar measures 1.5” in width and includes a lock/unlock lever for a secure hold and a rubberized interior lining to protect your bar.

There are two magnets on each face of the collar, and they are mechanically pressed into specially machined pockets (rather than glued) to ensure their stability. All of our MAG Collars are backed by a 2-year warranty.

Rated 5 out of 5 by from FANTASTIC Product Very happy with these. The magnetic feature comes in hand while working with a barbell on a rack.They stay on real tight. I would recommend these to anyone.

Rated 5 out of 5 by from Collars that hug like a big Siberian bear. I have been about a month on using these collars with some comp plates. This setup allows for the collars to stick to the metal insert on the plates which creates a very close hug between plate and collar. All I have to do is slide the plate to the end of the sleeve and the collar takes care of the rest. There is very little to no movement once the collars are clamped down. Very easy to remove and slip on. Only thing to be aware of is if you flick the handle when trying to undo the clamp, it can spring up quickly and catch your knuckle. Just grab the whole handle to avoid this issue. I learned fast.

Rated 4 out of 5 by from Nice These are a little stiff but feel like they will break in well. Magnets on both sides is unexpected plus.

Rated 5 out of 5 by from Perfect fit - very firm hold on plates Extremely tight hold on my plates, makes the entire lift feel more secure. I really like how convenient it is to store them in my rack when I am changing weights or and done working out. It was a bit of a splurge as I also have a pair of the HG 2.0’s, but all things considered I would recommend this collar. Great purchase. One thing to note, these collars offer a tight fit. So when you are loading it onto the sleeve, make sure that the lever is pressed all the way back and the collar is completely open. When you are closing it, use your thumb to press down on the lever while resting your hand in the protruding metal piece labeled rogue. This will prevent you from pinching your fingers with the lever.

Rated 5 out of 5 by from Great Collars They hold the plates on very well. They are snug fitting when putting them on and taking them off, so if you are in a hurry buy the spring clamps. If you want to know your plates are secure, the these are the collars for you!

Rated 5 out of 5 by from Magnetic Collars I bought these collars only because they're magnetic. I thought that was super cool. I also bought a pair of cm-1 rogue collars and I like them a lot more (use these on deadlifts). But having the ability to just stick the collars to the rack is so convenient and just awesome.

Rated 5 out of 5 by from Why didn't I think of inventing these? I just got a pair of these collars and they are great! The magnets were well selected for the job at hand since the collars adhere quite well to the rack, but not so hard that they are difficult to remove with one hand when you have a plate or something in the other hand. One word to the wise, when you open the latch on the collar, open it until you hear or feel a "click"...if you don't, you'll have a heck of a hard time getting them onto the sleeve of the bar. The collars are beautifully machined and hold the plates on very tightly. I'll be buying more of these!
