OSO Mighty Axle Collars - Red


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.

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