How It Works — 02
How to convert a standard squat rack into a competition-grade rotating pull-up bar. No welding. No fabrication experience required.
The problem
No manufacturer sells a purpose-built rotating pull-up bar for the Hang Challenge out of the box. The ones that come close are either fixed, too light, or not rated for the kind of repeated load a public event puts on them.
The Hang2Win rig solves this by starting with a proven, heavy-duty freestanding squat rack — then modifying it at a local machine shop to accept pillow block bearings. The result is a 750-lb rated, competition-grade rotating bar on a stable 48" × 48" base.
The full build guide is inside the operator package. Here's the overview of how it works:
The process
Start with a specific off-the-shelf freestanding squat rack. The package tells you exactly which one — widely available, ships to most of the US.
Take the bar and uprights to a local machine shop. Three operations: saw off the mount brackets, turn the bar ends on a lathe to fit the bearing bore, and drill two bolt holes per upright. The package includes a print-ready instruction sheet to hand the machinist — no explaining required.
Pillow block bearings from a separate supplier. Specific part number and supplier link included in the package. These are what allow the bar to spin freely under load.
Bolt bearings to uprights. Assemble the base. Insert bar, tighten set screws, check rotation. The package includes a full photo assembly guide — every step, every bolt size, every washer configuration.
Specs
Breaks down for transport. Assembles with basic hand tools — 1/8" hex key, 19mm and 24mm wrench or socket, crescent wrench.
Next
A working rig is half the business. The other half is knowing how to run the event: pricing, crowd flow, setup, and where to find the foot traffic that actually converts.
