About PRx Build Limitless Halo Arms
The PRx Build Limitless Halo Arms bring unmatched versatility to your training setup. Unlike standard jammer arms, these patented arms lock vertically, horizontally, or move freely for multi-directional exercises. Built in the USA for durability, they work with most 3x3 uprights and deliver a wide range of motion for strength training, conditioning, and accessory work.
Turn your rack into a multi-station training hub
Static attachments limit your exercise options. The Halo Arms change that with adjustable locking positions—17 vertical and 9 horizontal—so you can hit angles that normal arms can’t. Perform presses, rows, pulls, squats, and more without swapping attachments. Whether you want isolation or compound movements, you get the flexibility to adapt instantly to your workout plan.
