Monster J-Cup - 2" Sandwich

2” width, 10” height, ⅜” plate steel, 20 LB The side plates fit into a recessed, machined plastic core (2" wide) to prevent metal-to-metal contact. The hardware (that connects the plastic to the side plates) is also recessed, preventing the bar or a user’s hand from scraping against them. Welds are insides the side plates for a clean edge, and UHMW plastic is featured on the clasp and back plate to prevent damage to the uprights. A thin piece of rubber on the side of the clasp also softens contact between the clasp and upright when the J-Cup is swung into place.

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.
