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.

These are great
Took me a while to open these correctly, since you have to pull the lever back after the default open position to enable these to really fit on the bar but once that was out of the way they are awesome.

Great product
Really a solid on the bar, great locking mechanism and the rubber lining inside secures it even with 315 on the bar for over head drops.

Would not recommend
This is my fourth time writing a review, even after speaking to Rogue several times about why my previous reviews weren't posted. So here I am again to give my honest opinion. I have been using these collars for a year. They are very strong in terms of holding weight on the bar. If you want to slap five plates on and tip the bar up, they would likely hold. But for most gym-users, this is total overkill. Due to the strong grip, they are very difficult to get on and off normal barbell sleeves. The main issue, however, is that they have a plastic clamp. Since they are already so tight to get on, clamping them down requires a lot of force. When not done perfectly, the plastic will snap along the pin. Mine took about a 5 uses to break. Why make such a bombproof product, only to have the weakest part be made of the weakest material on the whole thing? The product should be "Metal Collars with Cheap Plastic Clamps". I would not buy this product again, especially at this price point.

nice looking collars, absolute garbage levers
I bought a red and purple set of collars for myself and my wife. one of the levers snapped on both sets the first time they were tightening down. I have used olympic collars for years and was real excited for these. Hopefully everyone else has good luck with them. Us not so much

Won't fit on standard bar
Bought these 2 weeks ago. They won't slide on a standard 45 lb bar. Too tight so they are useless to me. Possibly a manufacturing defect?

Very disappointed
Just got these, and they are the worst. They are so tight on the bar you can barely slide them down to the plates. Very disappointed.

TIGHT grip!
These collars are TIGHT! Lol I have yet to have one unclip or slide while cycling/dropping the barbell. Great product that matches so well with my custom purple Bella bar 2.0 :)

Solid, locks the plates well also axial!
When locking it has a very tight grip on the bar due to the rubber. The rubber gets squeezed to the sides of the collar, which fixes any axial clearance between the plate and the collar. This is a very good buy, if you want to have the plates fixed. I am using steel plates!
