The BD3X AXIS rack offers a fully modular system to boost training. Built with heavy-duty uprights and precise hole spacing, this rack works with many components and accessories. A fluid cable pulley system, powered by machined steel guide rails, connects to an aluminum bracket, reducing wobble and keeping the weight stack aligned. It contains aluminum bearing pulleys and a high-capacity wiring system. Select either dual 160 lb or dual 210 lb weight stacks.
