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 4 out of 5 by from Like the magnet - collars still move when dropped I got these as they are the heaviest duty collars Rogue makes, the magnetic attachment was a plus too. While the magnets work well and keep these out of the way when racking weights the collars will still move while doing olympic lifts. These lock on tenaciously but after a drop or two your bumper plates will start to move. Hoping to find a collar that won't budge eventually.

Rated 5 out of 5 by from Easily entertained I bought this knowing I didn't really need magnetic collars. After getting them and playing around with them, I really like them. At first I wasn't sure if they would work well and I was afraid I was going to break them but I figured them out and only thing I worry about now is getting my fingers caught when opening or closing them. Being able to slap em on the rack is so convenient I couldn't imagine going back to plain collars.

Rated 5 out of 5 by from Magnets are great! The magnets work great. The collars hold very well. They open wide so they come on and off the bar easily. They are still stiff so I need to watch my hands when I undo the clamp, as they spring back quickly.

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!
