Fully protect the knurling on your barbell with these versatile, heavy-duty Round Sandwich J-cups. 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. 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. The 5000 Series J-cups are designed for 3x3” uprights with 1” pins. They extend off the rack 4.9”. These cups are sold in pairs.
