Clamps tight on Powergainz unthreaded barbell. One thing to remember is to make sure bar is clean & to loosen the clamps at the end of your workout. Loosening allows the compressed insets to return to uncompressed dimensions thus insuring a tight clamping when put back into use.

I really wanted to like these but they simply do not work.Easy to put on/off but the issue is safety.They do not stay tight or are tight for that matterMore importantly they easily unclip.I find these to be particularly dangerous.Edit: ok so they don’t suck on a barbell.Definitely suck on dumbbells. So I’m a lot more pleased than initially.

These fit great on my 1-inch standard non-threaded barbell bar, and haven't had any issues with anything slipping. Weights wobble a bit when I set it up for deadlift, but mostly because I don't push the plates flush against the stop on the bar. And since I'm not tilting the bar to extreme angles in either direction, I'm not putting too much pressure on the clamps. When unloading the last plate from the bar on the floor, I usually undo each clamp just to make sure there isn't any unnecessary…

These clamps are too tight for a 1" bar. They don't expand enough to slide onto the bar.I thought perhaps my bar was the wrong size; however, it measures at just 1 inch. It's the clamps that are the problem.I don't understand how this could happen. I don't think there are bars that are smaller than 1 inch in diameter that the clamps would fit onto. And even if there were, the clamps were supposed to fit onto a 1" bar.Would not recommend; would not buy again.

Nothing much to say for this one.It does hold up a lot of weight plate (It can hold 15 pounds no problem) not sure about bigger weights because I only use this for dumbbells.

Didn't know what to expect with these; I figured either some very cheap generic collars or something decent. I was pleased with the product's appearance, function, and feel when I first opened the package. They seem durable initially and appear to be better than I thought they'd be, quality wise. A big advantage of these is using them on a long bar, where otherwise you'd have to squeeze a collar and push/pull it long distances. I didn't notice anyone else selling these colored ones, so that is…

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…

These are great looking clips for working out. I have them in both 1” standard and 2” Olympic for different bars that I have in my home gym.They work well, easy on and easy off and can be done one handed if necessary.I love that they come in vibrant colors - working out is not always my favorite thing so having some bright, colorful pieces helps to motivate me for a workout.Although I’m pleased with these clips, I’m hesitant as well because of the issues that others have had and I have concerns

Working out with dumbells, and barbells, etc. is ok, but changing out the weights can be a bit of a bore. We bought these to replace the couplings that came with our weight sets. These are soooo easy to clamp on and off and don't slip at all. I'll probably order some more! Working out is really beneficial to everyone. for stress, pandemics, and yes, civil unrest. I highly recommend it.

Product was as stated. Very easy to use. My sons bar was a very old non standard size. Was able to pop out on if the rubber inserts and shave it down and place back in clamp for a perfect fit. Would purchase again.

Fits my standard 1" cap barbell perfectly. Easy slide on and off. Only dislike is I ordered the red ones, but actual color is not as shown in picture. More of a darker red than the more radiant red shown in purchase picture. But functionally, no problems. They dot perfect and easy to use.

I’ve read a couple of reviews, that ding these clamps for the insecure(?) lock they provide. Granted, if I was a HEAVY weight lifter, and these were my only weight locks, for quick weight changes, I might be concerned. I bought these, as "insurance” clamps, to supplement the spin-lock weight locks, which invariably spin, WHILE you’re lifting! This is annoying at best, but can be dangerous, as well. Having these, combined with the spin locks, ensures the weights aren’t going anywhere, and stops…

I had a similar pair I used on Olympic bars, and bought these for home workouts with a 1” weight bar. They worked fine until recently. One side of my weights started slipping, and I thought it was me being careless with getting the weight snugged to the bar collar and this quick collar tightened.I found a pin on the floor the other day (round, about 3/4 of an inch long, maybe 3/16 in diameter) and then another. I thought they were roller bearings that came out from my office chair and threw…

I love these clamps for my straight bar. However they don’t work well for plastic 1in dumbbell bars, or 1in easy grip bars. They tend to slide off pretty easily. They’re perfect for the straight bar though!

Unfortunately I assumed an inch was an inch and didn't measure my bar in mm. Turns out Yes4All bars are 30 mm so these will not fit my bar, 5 mm too tight. They seemed to be of decent quality and easy enough to use, but because they didn't fit (couldn't even muscle them on), I had to return them.

These are so much better then any other barbell or dumb bell clips. There so easy to use and work amazing love them Thanks for attention!
