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

Good and...meh....
These work pretty well. They have replaceable rubber (overpriced rubber), and can therefore last indefinitely, but they are heavier than my last collars that didn't have replaceable rubber within. I should have gone with the magnetic clips. I think the convenience of the magnets would outweigh the longevity of these collars.
Yes, I recommend this product

Plastic Latches are faulty
I bought quite a few of these for my gym about a year ago. Since then, many of the latches have broken off (as shown in the picture) or don't have that "snap" to them. If you are using the clips for personal use, they should be ok. That said, the latch definitely needs work...

OSO collars need attention
I agree with the other reviewers that stated the collars are good but the latch needs much to be desired. I expect more from ROGUE than these faulty things. Heck I only had them a couple of months before they failed.

Big waste of money
I really wanted to like these. I enjoyed swapping out plugs. Had these for over six months. This morning one of the levers cracked. Completely useless now. I should have just bought the cheap collars

Clamps are trash
I bought these and had them break twice now. The plastic clamps on these are just garbage. I had these years again and lost them, but the collars were so much stronger back then. They are easy to break now

OSO collars are the bomb!!
I was looking for oly collars that wouldn't budge if I dropped them from overhead, and that were well made...I found that with the OSO collars! Love the color choices and that the rubber grips can be customized too! Excellent add to my gym and I will buy again!!
