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. 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

The standard rubber plugs included with these OSO collars are gray, but customers can opt to add a 4-pack of extra rubber plugs to their order in any one of a dozen additional colors. Check them out here.

Rated 4 out of 5 by from OSO CM -1 Collars- Just The Product I am very happy that I bought the OSO CM-1 collars. I like them much better than the spring collars. This only drawback is that you have to hold the collar with one hand in order to snap the lever closed with the other to prevent any accident. Even with this drawback I recommend this piece of equipment without reservation.

Rated 5 out of 5 by from Best non-weighted collars EVER! If you want collars that don’t add a lot of weight then these are hands down the best. They actually stay put and don’t move in between reps and even in between sets. Don’t waste your money on anything else. Easy to put on and take off.

Rated 5 out of 5 by from Solid I bought them for my Cerakote Bar. For sure not the last of them.

Rated 5 out of 5 by from Zero Slip Own several of the other line of OSO collars and these are by far the best. Not only do they not slip, they are also the easiest to put on and remove. Recently did 55 C&J at 185#. Every rep dropped from overhead. Nothing moved.

Rated 5 out of 5 by from Great Product! I have been really impressed with the performance of these collars. Once they are clamped down on the bar, they stay put until you take them off. No slippage over the course of a workout!

Rated 5 out of 5 by from Rock Solid Great product and fantastic hold. These are definitely worth the price and I expect them last a long time. Use a tiny bit of dish soap and the rubber plugs drop-in to their seats easily.

Rated 5 out of 5 by from Great product I have only used the cheap plastic collars at my local gym. I have to say that the Rogue collars are of the finest quality.
