OSO 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 standard OSO barbell clamps. The OSO Axle Collar is available only in olive green, so it will always be easy to distinguish from your other gear-shaped OSO collars.

The Axle Series is manufactured in Colorado and compatible with a broad spectrum of specialty bars, including the Rogue Axle and 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 Axle Collars is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Solid but beware we use OSO clamps at our box and fell in love with them from day one. I just received a pair of these new OSO Axle Collars in exchange for a pair of previous axle collars [red plastic] that broke. and like they say in the copy above, THESE WILL NOT FIT ON ANY OTHER BARS other than your axle bars, and farmer carry handles. and that's fine if that's what you are buying them for. just know that there is no way to get them onto any other barbells before you buy them. and like I said, they seem very SOLID too.
