Turn the Rack You Own Into a Cable Gym
Already own a Profile PRO or CORE folding rack? This is the upgrade. The ARK Weight Stack Attachment bolts a dual selectorized cable system onto your existing rack and still folds to just 6" from the wall.
This listing is the attachment only. The Profile PRO folding squat rack is not included. Choose from six logo plate colors to match the rack you already have.
Key Features
Built for owners of a Profile PRO or CORE rack in 95", 89" or 81" who want cable training without buying a second machine.
Pin-select resistance on both sides for unilateral and bilateral work.
The attachment keeps the folding footprint that makes a PRx rack worth owning.
The selected weight is the weight you feel, with 62" of cable travel on a 95" rack.
The patent pending Retractor keeps cable tension managed through every fold cycle.
Match or contrast your existing rack finish.
Description
If you bought a Profile PRO rack for the space it gives back, this attachment is how you add commercial-gym cable work without giving that space away again. Two independent 160 lb selectorized stacks mount to your existing uprights, and the whole assembly retracts with the rack to 6" of wall depth.
A 1:1 pulley ratio keeps the math honest, and 62" of cable travel on the 95" rack (54" on the shorter uprights) covers lat pulldowns, low rows, flys, face pulls and standing presses. Pair it with the PRx Axis ecosystem and a footplate for belt squats, leg curls and preacher curls from the same footprint.
One important note before you order: the ARK folds up taller than a bare Profile PRO rack, so its minimum ceiling height requirements are different. Check the compatibility table below against your room. A multi-grip or straight pull-up bar works; a kipping bar does not. If your ceiling is lower than the table allows, talk to us before you buy and we will help you find a fit.
This item is a preorder shipping in late September 2026.
