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

OSO CM-1 Metal Collars is rated 4.8 out of 5 by 36.
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 Never without them now I bought these at the 2017 Games after seeing them take a beating on the competition floor. My lifting partner and I put them through 16 rounds of 17.5 in 15 minutes and they didn’t budge. Everyone else was readjusting their bar and plates, ours held fast. I bought them on the final day of the games and received free engraving from a great bunch of people at the OSO booth, highly recommend! Get the metal ones, they’ll last you forever.

Rated 5 out of 5 by from Easy to take off and clamp down hard These have been great so far. I've had them for a few weeks now. Opening and closing them were slightly difficult the first few times but now they snap on and off quite easily. I love these collars, I couldn't be happier with my purchase. Listen to what other reviewers said, however. Make sure you open the collar with one hand. If not they will come back and bite you. Also, there are two "open" positions. The first is after the initial pull. The second is a very small amount further which makes a audible click. This opens the collar fully so you can easily slight the collar on and off the bar.

Rated 5 out of 5 by from Super I bought them to replace some useless spring collars on my Olympic dumbells as you will see them. The CM1 is easy to apply and disengage with 2 positions. The bare iron plates are now noiseless which is great for the neighbors and me as they otherwise make a racket! They are light and small enough to take to a gym. they do the same for the barbell however I have some nicer IPF rated ones for my one at home. I have never dropped weights from height so they are unlikely to get damaged. Very grippy and easy to remove, excellent quality I'd recommend, get some for the gym!

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 The bar has been raised Bought a pair at the games and quite simply these are the best collars money can buy. An absolute steal and made in the USA. Thanks OSO, for proving again that the best products can still say "Made in the USA".
