Best J-Cup around!

These are sturdy and hold the rails tight. I have the BoS Yoke and these are great. I feel safe under them. Some chips and scratches when they arrived. Only issue is it will tear up the paint. If you care about the paint, I recommend lining the inside of the cups with painters tape. The tape sticks and I haven’t noticed any chips or dings since. The knurl of the bar will chew into the cup lining but after a few sessions it stops and you just brush the bar. A must have if you have a BoS rack or stand.

Sturdy and reliable

These j cups are solid, no confidence issues using them. They do sometimes rotate out a small amount but not enough to be concerned. I think my only criticism would be the metal on metal is already wearing away some of the finish on my new rack - some nylon or uhmw plastic on the interior would help this but at this price point I understand why that’s not there. Overall sturdy and reliable, recommended for sure.
