Ghost Strong
Ghost Roller J-Cup
The Rig-Mount Speed Bag Platform was inspired by a request from multi-time boxing world champion Robert "The Ghost" Guerrero, who wanted his speed bag more centralized and accessible in his training space. The attachment includes a set of 0.1875" thick laser-cut steel brackets (holes 4" on center), all required mounting hardware, and a 24" diameter platform in Red Oak .
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.
