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 Great product. I use these primarily with the Rogue Calibrated steel plates. Very sung fit on the barbell collars. I really like the rubber inserts. There’s no paint chipping on my plates because of it.

Rated 5 out of 5 by from Perfect! I bought this pair a month ago and it’s been absolutely perfect. They are very easy to clip close and will not bend.

Rated 5 out of 5 by from these are awesome I picked these bad boys up because i'm tired of using the plain old spring collars that don't hold well when you got anything over 315 and then with wear and tear its like the struggle to hold 95lbs. Pros: 1. Super strong grip, didn't even move with 415 lb deadlifts 2. Easy to latch and unlatch 3. really durable 4. The fact that you can replace the plugs is also great Cons: 1. I could see that maybe in the future because the latch is plastic it might break with just wear and tear. but it seems heavy duty enough that it would last a long time. 2. I ordered mine in blue and I got two different shades of blue. its really no big deal but if you advertise different color ways I would hope that you get those specific colors. other then that I would defiantly recommend this products. If your a stickler about colors matching perfectly then i wouldn't recommend it. all in all though these are really awesome collars and for the price i think they are well worth it. Ill most likely buy again.

Rated 5 out of 5 by from Simply the best! I have bought many barbell collars for my garage gym over the last 8 years, these OSO collars are hands down the best I have ever used!

Rated 5 out of 5 by from Great Clips Bought these a month ago for my wife and the plastic version for myself. Metal ones are much better. Easier to clip. The plastic ones get the job done but are a little tedious for clipping on and off. Works well for metcons when you use the same weight for the entire workout.

Rated 5 out of 5 by from Awesome collars! Definitely glad I purchased these. Picked up a new Eleiko barbell and needed collars to suit it - the old spring clips wouldn't have done the job. They take some wiggling to get on the sleeves at first. But after your first set of snatches or cleans, the rubber inserts settle in and they go on and off effortlessly. Also, they DO NOT slip when locked in place. Great collars again - would recommend.
