I bought these and they aren't gripping tight enough on new dumbbells. The standard collars keep weights tight but lockjaws let weights revolve around

Did not have that problem, yours maybe defective, or a different type of bar.

Thanks for your input, I really appreciate it. I find that with the spin lock bar I have the collars are always coming loose.

I have the Troy Lite barbell which has a 1" diameter bar and the 1" Lock-Jaw Collar works perfectly. I think, as mentioned here, Olympic bars have a thicker diameter bar.

Yes the Cap Barbell Weight Bar I bought came with threaded collars. The collars have internal washers that help to keep the collar tight against the weight plate. The collars stay tight on some exercises, but not all. I would recommend a spare pair of clips for some exercises.

They'll work with any kind of dumbbell as long as the handles are round. The hooks cradle the dumbbell handles, not the dumbbell itself. Sounds like a nonsense answer but that's the best way to put it. My only concern while using them was putting them back on the bar. I found the view somewhat obstructed so I had to kind of fell my way back to the bar. It depended on how wide of a grip I was using on the dumbbell press. Overall, they're worth the money. Good luck with them.

No, I have both and tried it out of curiosity. These collars only work with a non-threaded bar.

It's been awhile so I can't be sure. You can email the seller to be sure. Definitely tape them inside the collar. Sorry I couldn't be of more help.

Hi, porchpotato. I don't own and haven't used this product, but I own a pair of similar RAWBuiltTech standard-size barbell collars. I don't have one of those interchangeable-plates dumbbell sets, but I can say this much: even a 25 LB (old) Weider weight plate and a pair of (much newer) 5 LB Weider plates (or "disks") press against the clamped-on barbell collar (when the barbell is tilted even moderately). The 35 LB weight-plate trio then causes the barbell collar to shift toward the end of the barbell sleeve, if only by a fraction of an inch. Oh, I know that virtually no-one is tough enough (or dexterous enough) to try handling and curling a 70 LB dumbbell set made with 25 LB weight plates, but I hope my reply is a bit useful ...

I had the same problem. They are smaller than the originals. But with added pressure and force. I got them to stay on my unit.

Any standard plates not Olympic plates should work.I would not recommend these dumbells though .The spin collars are junk and will chip and leave metal chunks all over

1) Yes they would fit the bar, however they are pretty large for a dumbbell being about 15 inches across & an inch & a half thick. I use them on a barbell. 2) Depends on the set.

They don't lock into place in the tray, so they might not want to stay in place. When you have all 7 in place, they are nice and snug, but I still think you might want to try a large rubber band length-wise around them. I really love them, though. Still using them, and the snap shut hasn't loosened at all.

I found that if I loosen the strap, I am able to do a better wrap on the bar with these. You should have not problems with them, check the webpage for sizing chart.

I primarily use these straps for dead lifts and rows. They work great and allow me to train well beyond my hand strength. I have used them for pull downs, but never chin ups. I would imagine they would work fine as long as the bar is low enough to get them wrapped properly. If you have to jump up to the bar you won't be able to get them on unless you used a stool or chair.

Yes, they fall off constantly during use. I re-tighten them between every set. I've gone as far as wrapping the threads in tape to give the collars some friction.

They can be tight from corrosion etc. I used a pair of pliers and mine came loose.

Grip 4orce can definitely be used because that's just a matter of you squeezing down on them. As for Fat Gripz or Iron Bull goes the bar is thin and you'll get that annoying spin. A simple remedy is get some thin flexible rubber padding to place over the bar before applying the thick bar adapter of your choice. Yeah it's a bummer you just cant get a true 1" barbell bar. It's actually 7/8". 14" long dumbbell handles are the same thickness as this 5' bar, but 17" dumbbell handles allow adapter grips to fit snuggly. Go figure.
