Rogue OSO Barbell Collars 2.0

Version 2.0 of the Rogue OSO Barbell Collar combines an improved clamp lever mechanism with the original model's 6061 Billet Aluminum construction, resulting in superior durability. This Rogue-branded version of the OSO Barbell Collar, featuring an innovative, aircraft-grade aluminum clamp, is designed and manufactured in Columbus, Ohio. Sold in pairs and equipped with a rubberized interior lining to protect the bar, OSO 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. It’s the OSOs unique look, though, that generates the most attention. With this design, that means an industrial gear-style shape in gunmetal gray with the Rogue logo down the side.
