OSO Mighty Axle Collars

Our lightweight OSO Mighty Axle Collars are quality-made, economically priced, and specifically designed for specialty barbells that use 1.5" pipe with a nominal outside diameter of 1.9". This includes compatibility with the Rogue Axle,TB-2 Trap Bar, and Log Bar, as well as the bars of the Rhino Belt Squat, RH-2 Rogue Reverse Hyper, and Rogue Donkey.

Manufactured in Columbus, Ohio, all OSO Mighty Axle Collars feature the same aircraft-grade aluminum construction, rubberized interior lining, and locking clamp mechanism as our OSO Mighty Collars. The key differences, besides the sizing, are the notched flanges and red anodized finish—making it easy to identify the Mighty Axle Collars as your grab-and-go option for specialty bar training.

Approved for the new Army Combat Fitness Test (ACFT)

This product has been officially approved for use with the United States Army’s Combat Fitness Test, a 6-event readiness assessment that’s replacing the previous 3-event Army Physical Fitness Test in 2020. The grueling new ACFT is neutral across all genders and age groups, and includes a strength deadlift, standing power throw, hand-release push-ups, sprint/drag/carry, leg tuck, and a 2-mile run.

IMPORTANT: Because of their smaller diameter, OSO Mighty Axle Collars CANNOT be used with standard 1.98" (50.4MM) barbells.

OSO Mighty Axle Collars - Red is rated 3.5 out of 5 by 8.
Rated 1 out of 5 by from Terrible product, highly disappointed I do not know how a company like rogue would even sell these. Most of their products are the either make or resale are of good quality. These are terrible, does not fit well at all on my fat bar or Safety squat bar. Just annoyed to no end at the moment. They take forever to get on and off and frankly won’t bother using them, go back to nothing instead. I feel bad writing such a poor review for what is wholly a well run company. But jeepers do not sell something you wouldn’t use.

Rated 4 out of 5 by from Nice collar for a nice price! Great collar for a fair price. The only thing that kept me from 5 stars is that the latch does not sit flush when closed. I usually lean my specialty bar against the wall when not in use, and i"m concerned that I may catch the latch on something. Other collars I've used do sit flush when closed.

Rated 5 out of 5 by from Really darned good I got antsy waiting for a decent bar to become available during the pandemic, so I made a barbell out of 1" cold rolled steel and some scrap 1.5" pipe I found at work that I welded together. Because of the smaller diameter of the steel pipe sleeves, I couldn't use crappy spring collars. I got these and they work perfect.

Rated 3 out of 5 by from They work, not as high quality as other OSO collar To be clear, these work and get the job done just fine. They are harder to get on/off than I would prefer.

Rated 5 out of 5 by from Perfect fit Unlike many, I read the item descriptions prior to purchase; which is why I bought these specifically for my trap bar. They fit perfect, are snug and the plates aren’t going anywhere. They also happen to look good in red which makes them easy to distinguish from my gray ones for my regular bar. I would definitely recommend!

Rated 3 out of 5 by from It’s not you it’s me Didn’t realize these clips were for a special bar not a normal 2” bar. It’s my fault, they just sit in my locker since I don’t know anybody that even has that kinda bar.

Rated 2 out of 5 by from Technically does the job, just...unpleasantly. Picked these up for a pair of Rogue farmers walk handles since the HG axle collars have been consistently sold out - definitely have some regrets. It takes 5x as long to get these on and off of the axle as it would using HG collars, so plate swaps are infuriating. They feel like they're almost too small for the axle sized bar, requiring significant wiggling and yelling at them to get them finally into position. The collars don't clamp, they wedge a plastic tab into place, so while the collar is nice and aluminum, the part you're constantly futzing with is plastic. Also, out of 4 collars, 1 shipped with hardware attaching the plastic locking tab already having fallen out. Still technically works since you have to wiggle the whole collar on anyway, but is twice as fiddly as the 3 others.
