Product Summary

Designed and manufactured in Colorado using aircraft-grade aluminum, OSO Mighty Collars offer many of the same benefits of the standard OSO Barbell Collar in an economically priced model.

These super lightweight collars–available here in Gun metal and Blue–are sold in pairs and equipped with a rubberized interior lining to protect the bar. OSO Mighty Collars deliver a secure, stable hold through repeated, high-impact drops, and allow easy adjustments or removal with a simple lever and lock/unlock mechanism.
