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 Carlito Tardy

I use this for my standard barbell that has spiral lock threads. They slide on well but sometimes get caught on the threads. The plastic seems ok. Could be sturdier. The inside have two rubber pads that huh the bar. For my case I just wanted them to put some resistance on the weight so they don’t move too much. It works. But as I use them the rubber pads get worn (3 weeks in) and it gets looser each time. When I got them one of the pads were off. I guess I could place something under the rubber pads to get them tighter. These don’t really have enough strength to hold the weights. The 25lb plate would wiggle out as I do a set of deadlifts. I would not use these for my dumbbells. I do have them on when benching and the weights are sliding off, but then again they don’t slide off when I have no locks on. I’m sure with a non threaded end it would work much better.These are easy to use. Snap off and slide out. Slide in and snap on. Beats turning the locking nut for 10 seconds as fast as I can.
