OSO CM-1 Metal Collars

The OSO CM-1 Metal Collar introduces some innovative new engineering elements inspired by customer feedback and advances in precision technology. This includes rubberized interior plugs for a superior hold on the bar, an updated handle, and a fresh new design made from OSO’s top-grade 6061 Billet Aluminum. The CM-1’s cam locking clamp mechanism secures the collar in place for consistent stability and peace-of-mind through even the most intense weightlifting regimen.

OSO CM-1 Metal Collars are sold in pairs and sized to fit all standard 50mm Olympic barbell sleeves. They’re currently available to order in three colors: Red, Gray, and Blue. A budget-friendly polymer version of this design is also available separately.

Instructions for Inserting Plugs

  • Step 1 – Align plug so that it sits evenly atop the slot that it will be pressed into
  • Step 2 – Gently push with both thumbs, alternating from the top to the bottom, and repeat. This will slowly work the plug into position in a small amount at a time. (If you try to force the plug in, it will tend to stick, and will then require more effort than necessary. It may help to get the sides of the plugs wet so that they slip in more easily)
  • Step 3 – Once the plugs are in place, it may take a couple of clamping cycles on the bar to get them completely seated. This entire process should only take a few minutes for each collar

Rated 5 out of 5 by from Best collars I’ve ever used These collars are the sturdiest and most secure I’ve ever used. Once they’re secured there’s no way the weights are sliding, I can’t wait to use them for heavy deadlifts

Rated 4 out of 5 by from Great collar, but not as good as the OG I bought a pair of these OSO Titan collar, when someone else decided they wanted my old OSO collars more than I did. They are very ease to get on and off the bar, and I like how many colors and combos you can create. However, I find that these collars still slip from their seat once clamped. I feel that the older style would hold a lot better. I don't think I had to reclamp them a single time. With these I have to reclamp once or twice during a WOD with some type of Oly movement. I am just an average CF athlete and I don't throw around huge amounts of weight. Overall its a [email protected] good collar!

Rated 5 out of 5 by from Awesome These collars are great. They fit very snugly on the bar even after repeated overhead drops. Just be a bit cautious when removing the collars as they have a little snap to them when you unlock the arm. Overall, these are a solid pair of collars that will last a long time.

Rated 5 out of 5 by from Love - wish I could have gotten them 'engraved' These are awesome, don't move, and are easy on / off. I just wish I could have gotten them customized with a tag line like Oso used to do!
