These collars hug my barbell’s sleeves like your least favorite aunt who won’t let you go (or stop talking about how grown up you are) at a family reunion. You know, the one with the grizzly bear hug that won’t stop...
Initial use, the collars would not go on a standard olympic bar. I sent a question about the item through SOFLETE on FB. They got back with me within 12hrs. The collars will adjust past the vertical open position. Push till you get a noticeable/Audible click. Collar will be fully open. Great kit, better than what most gyms offer.
