Rated 5 out of 5 by from OSO Mighty Collars These collars are awesome. I picked them up because I was tired of the typical gym collars that are hard to get on and off. These slide on easily and come off easily. I would definitely recommend these to everyone.

Rated 5 out of 5 by from Solid AF I was a little unsure about these before buying and immediately after I started using them but they’ve performed excellently. And of course they look great and are of fantastic craftsmanship like everything from Rogue. LFG!

Rated 5 out of 5 by from Simple, Strong, Effective My wife and I have been using these in our home gym. They are amazing, keep those plates rock solid, and don’t budge. I would highly recommend. The only consideration I’d have in the future is for buying clips with taller lugs. If you have and plates with holes that are in the larger size (like my metal change plates) you’ll be wishing you had that little extra height to capture the plate and really button things up. That being said, these haven’t given me any issue. They look great, work great, and feel like they are built to last a long time.

Rated 5 out of 5 by from Great buy I had old collars difficult to open and to move on the bar, it was long and tedious to change plates. Now it’s quick and easy, even outside when it’s freezing
