OSO Red Axle Collars


OSO Axle Collars

Designed exclusively for use with 1.9" OD specialty bars, OSO's Axle Series collars feature the same aircraft-grade aluminum construction and rubberized interior lining as the OSO barbell collars. Normally available only in olive green, this Rogue-exclusive version of the OSO Axle Collar comes in red.

The Axle Series is manufactured in Colorado and compatible with a broad spectrum of specialty bars, including the Rogue Axle, and the Multi-Grip Bar. The locking clamp ensures a secure, stable hold through repeated, high-impact drops, and allows easy adjustments or removal with a simple lever and lock/unlock mechanism.

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

OSO Red Axle Collars is rated 4.3 out of 5 by 6.
Rated 5 out of 5 by from billsintic, theyre called "axle" collars. it seems pretty self explanatory. also, the description specifically says they're for 1.9" OD specialty bars...

Rated 5 out of 5 by from Solid collars Picked these up on BF to go with our stubby axle. They work great while providing a pop of color so they're easy to separate from our other collars. These hold weights tight and we haven't had to snug them up as we sometimes have to do with collars on other bars. Notably we've even stored this vertically with the weights still on and the collars don't budge!

Rated 5 out of 5 by from Awesome collars for your axle type bars. Had the plastic ones but really wanted a set made in America. These are great, on and off easy they stay snug on the bar. Heavy duty with the same great OSO quality.

Rated 5 out of 5 by from Smaller inner diameter than OSO Pro Collars On the Rogue Axle barbell, these Axle collars are actually a tighter fit than the OSO Pro Barbell Collars that I use on my Klokov barbell. Since OSO products don’t come with instructions, I’ll mention here that the lever has three positions: closed, released, open. Gently moving the lever into the open position makes taking OSO collars on and off much easier. The color of the pair I received is much paler than what’s pictured here but these still keep the plates on the bar.

Rated 5 out of 5 by from Works as advestised I bought these along with a trap bar. At first I couldn’t make them fit the bar. The collars seemed too small. I realized after looking at the lock cam mechanism the collars will open wider than I first tried. Once I pushed the lever fully open it slipped onto the tap bar with out a problem. The collars work great.

Rated 1 out of 5 by from Does not fit on trap bar These collars were depicted on the same page and next to the trap bar, as in “these are the collars you need.” Well, they don’t fit (too small). They look great and probably work well for a small bar, just not a trap bar.
