More information

The J-Cups are designed and built for our 3x3 rigs and squat racks, but they will fit many other brands of rig. Please note the pin size is 24.5mm and is not powder-coated like the rest of the J-Cup, but chrome-plated instead. 24.5mm is .96", so if your rack features 1" holes, these J-Cups WILL fit.

Awesome j-cups

I have been looking for something that would work on my rack. It’s rather old so there’s not much out there as far as accessories. Then I found the j-cups at Fringe Sport. I wasn’t sure if they would fit perfectly but at least I knew they would fit the holes. I was almost right, they don’t exactly fit my rack, but with a small modification, they work perfectly!

Nice customer support

The J-CUP is functionally working as expected despite there is cosmetic cosmetic blemishes on the UHMW. Customer service is excellent.

Great experience; the J-Cups fit on my Ethos rack just like the review said.....PERFECT The only thing that I saw that could be an issue is a need of some safety feature to keep them from moving; my existing cups have a magnetic pin to keep them in lock
