FITS PERFECTLY THANKS
My current dumbell collars broke and was looking for new set. As my dumbells are older and 28mm threaded diameter I had issues finding collars that fit. Tried spring clips and the plastic clamp type and both were no good as didn’t last. Maybe they are suited to the non threaded bars. Found this site and they arrived today and fitted perfectly. Great product and arrived within 2 working days. I wish I would have seen this product earlier as I wasted my $ on those clips and clamps. Thank you very much you guys are awesome.
Anyone with 28mm threaded dumbells these fit like a glove and very strong.
Thanks again you guys are great!
