Fully protect the knurling on your barbell with these versatile, heavy-duty Round Sandwich J-cups. These cups, which are compatible with 4000 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. Round cups feature a super secure “doesn’t move” resting point and a dual-lock wraparound design for extra peace of mind with heavy weight on the bar.
These cups fit standard and specialty bars with diameters less than 40mm. These J-cups are tough, with a weight capacity of 1,000lbs. They feature high-end finishes, such as a stainless-steel REP logo plate, and they’re laser cut and bent with rounded corners for safety. The bottom liners are one piece to prevent rotation of the liners. The 4000 Series cups are made for 3x3” uprights with 5/8” pins. They extend off the rack 4.9”. These cups are sold in pairs.

Due to machining variables, we cannot guarantee compatibility with other non-REP products.
Cosmetics: The new cups have a metallic black finish with a stainless-steel backing, so the REP logo really pops. This is the reverse look of the original design.
Functionally: The new J-cups have an overall taller landing zone height, which allows for more surface area when re-racking. A smaller lip allows for easier re-racking, while still holding your barbell secure. The higher position on the pin from the C-cup makes it easier to install the J-cup, due to less rotation needed. And the new, single C-cup bracket instead of the previous dual brackets allows for ease of installation without compromising stability.
