Ghost Strong
Ghost Roller J-Cup
Round Sandwich J-Cups
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.
What is a Rack Attachment?
What rack attachments are
Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.
Compatibility comes first
An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.
