Ghost Strong
Ghost Roller J-Cup
Mutant Metals Handles are precision-machined, fully-knurled grip attachments built for the Mutant Metals UDA (Ultimate Dip Attachment) and ARC cable/landmine systems, sold in pairs across five lengths (5”, 8”, 12”, 15”, 18”) and three materials (aluminum, steel, stainless steel). On the older UDA design they lock in with CNC-machined knurled knobs; on the newer ARC frame they thread directly into an internally threaded barrel, dropping the separate knob entirely for a quicker tool-free swap. Independent reviewers who bought and installed their own sets describe them as overbuilt and tightly toleranced, holding position under sustained cable and landmine loading with no reported loosening. Aluminum keeps weight down (about 8.5 lb for an 8” pair versus roughly 14.5 lb in stainless) but is rated for vertical/ARC use only – not horizontal loading like dips or pull-ups, where steel or stainless is required. The main tradeoff flagged is cost: a fully kitted-out setup with a frame, handles, and flanges commonly runs past $200, and one reviewer noted the 18” handles ship without tapped ends for the optional flange accessory.

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.
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.

Mutant Metals’ Handles are the interchangeable grip end of the Mutant Metals UDA and ARC attachment systems, and the standout dimension is build quality: CNC-machined, fully-knurled, 1-3/8” diameter, made in the USA, and – on the newer ARC frame – threaded to screw directly into the barrel with no separate locking knob. Three independent YouTube reviewers who bought and installed their own sets all describe them as overbuilt, tightly toleranced, and secure even under sustained cable and landmine loading. Versatility is close behind: five lengths (5”/8”/12”/15”/18”) and three materials (aluminum, steel, stainless steel) cover everything from tight tricep pushdowns to wide lat pulldowns, with optional flanges and color choices layered on top. The weakest dimension is value – reviewers repeatedly flag that a fully kitted-out pair runs well past $200 once handles, flanges, and a frame are added, and one reviewer noted the 18” handles ship without tapped ends for the flange accessory despite it being sold as an add-on.
