EMFK! Olympic Barbell Clamps, Quick Release Non-Slip Barbell Collars Clips for 2-Inch Pro Olympic Weight Bar Plate, Lockdown Weight Clamps for Workout Weightlifting Fitness Training

They fit, too! I have an Olympic Barbell Set that I obviously add weight to as I go. I use the clamp collar to permanently hold the two fifty pound weights in place. As I add additional weight, I use another set of clamp collars to keep them in place. The clamp collars are reliable and hold the weights firmly in place preventing movement. Plus, they're very easy to clamp and un-clamp when changing plates. Lastly, I went to the clamp collar after too many years of frustration with the metal spring collar the set came with. This is a case where new and improved beats old and frustrating.

The clamps are a little tight to lock, at first, but that was to be expected. I've been using them for a week and love them! They seem to be made of quality parts and the rubber on the interior insures that they stay in place while being locked into place. I would buy them again, for sure.

Works well and does what it is supposed to do

They work good if your bar has the lines/grooves cut in the area you slide the weights. Can't speak for the other styles of bars. Price was good so if they hold up I'll be very happy.

Works good but hard to take off. May need to broken in but I got same type from Dicks and they work perfectly.

I wrote you all and nobody responded to my questions. Now, I see that it is too late to return as of yesterday. One of the clips broke as I was tightening it. I believe that it was defective but all 4 sleeves are very, very tight on my olympic bar. Alfredo

I use them over and over, my kids use them over and over again. They are not a cheap product. Just ordered me some more

So great! Easy to slide onto the bar and even easier to snap them into place! Love having these.
