OSO CM-1 Metal Collars 2.0

Version 2.0 of the OSO CM-1 Metal Collar combines an improved clamp lever mechanism with the original model’s 6061 Billet Aluminum construction and innovative interior plugs. The result is a superior, close-grip hold that secures the collar in place through the heaviest weight loads and high intensity workouts. 

CM-1s are sold in pairs and sized to fit all standard 50MM Olympic barbell sleeves. The collars are available in a range of colorway options (Black, Blue, Orange, Pink, or Red) and come standard with a set of (4) black rubber plugs, which customers have the option to swap out with more than a dozen other colors in order to match the aesthetic of their bar / gym / team, etc. Extra plugs can also be purchased a la carte as needed.
