PEHADU 2PCS Barbell Collar 2 Inch Olympic Barbell Clamps Quick Release Lock Clips Dumbbell Buckle Weight Lifting Bar Clamp for Gym Fitness Exercise Body Building Workout Weightlifting Training

These accomplish their goal.The band is a little “tight” around your typical Olympic sized collar so securing rubber catches as you are sliding it on, but for $10/pair, these are much nicer than the metal clamps which sound like nails on a chalkboard as you slide them on.The safety lock is understandable but it is difficult to unlock one handed (imagine holding a weight in one hand as you try to unlock these). But aside from that, I use these every time I’m at the gym because I can’t stand the metal ring clamps.
