Fully protect the knurling on your barbell with the versatile, heavy-duty Round Sandwich J-cups 2.0. These cups, which are compatible with 4000 and 5000 Series power racks, feature plastic lining for total protection of your barbell and the power rack uprights. Plus, the hardware is on the side of the cups, so there’s no metal contact with your barbell. These J-cups are finished with a metallic black powder coat that’s resistant to chips and scratches to minimize rust and keep your home gym looking fresh for years. Round cups feature a super secure resting point, so your barbell won’t slide around or move when it’s racked.

These J-cups work great on my REP rack. They are solid, stable, and do exactly what I need them to do. I also opened mine up and sprayed the inside plate with white liquid rubber so they match my rack better, which made them fit the look of my gym even more.

These are high-quality J-cups, exactly what you’d expect from REP. They’re solid, well-made, and do exactly what they’re supposed to do — hold the bar securely with a nice round sandwich design. The fit on my custom rack is good, and they feel stable during heavy lifts. No frills, just reliable performance. Not much more to say — they’re straightforward, high-quality J-cups that get the job done without any issues.

Decent J-Cups, no issues with them. They’re really not any different than a standard Jcup.

These are great j-cups as they have a good profile and have good uhmw to protect bar. They are easy to get bar in and out.

Solid j hooks that easily fit on a rep rack. Already has a good UHMW coating so it won’t scratch up your rack. Taller than the 1.0s so the positioning is different, but that doesn’t really matter.
