Review on Quick Release 1 Inch Barbell Clamps - Locking Collar Clips For Standard Bar Weight Plates - Ideal For Fitness Training, Weightlifting, And Bodybuilding By Greententljs by Sonny Flores

I had a problem with one of the pair of clamps. When I contacted the seller the problem was rectified in short order. I highly recommend the seller.I like that these make changing plates easier than the spring clamps I was using before. The only caution I have is to be careful of the weight being held. Each clamp, on the painted 14" dumbbell bars I use, is able to support 35 pounds. When I tried 40 pounds, the clamp was not able to hold it. It may have done so if your bars are longer or have a different finish.
