REP’s Flat Sandwich J-Cups 2.0 are the upgrade pick over stock J-cups: a urethane liner protects your barbell and a plastic backing protects the upright, they’re rated to 1,000 lb, and the taller 2.0 body plus a larger opening makes re-racking easier and fits oversized specialty bars. Pick the 4000 Series for 3x3 uprights with 5/8-inch pins or the 5000 Series for 1-inch pins. Compare REP’s Standard J-Cups 2.0, Competition J-Cups, or the Round Sandwich J-Cups 2.0.

Fits 3x3 (5/8 in or 1 in pins)
Liner urethane (bar) + plastic (upright)
Capacity 1,000 lb

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.
