Are you a proud owner of a Royal Squat Rack SX-15 or Royal Squat Rack SX-10, and you want to expand its functionality further? It’s quite simple, the only thing you need is a Kingsbox yoke kit. With it you can transform your normal rack into a yoke or a sled. The set contains a crossbar the so-called carry bar and four bumper carriers, for loading on the additional weight. The crossbar has a diameter of 60mm, which will lay perfectly on your back and will provide with evenly weight distribution, on both sides. It’s installed in just a few seconds, thanks to it’s quick fit system.The Bumper carriers are simply attached to the Rack leg supports and perform two tasks: to carry the bumpers and, thanks to the slides on the underside, transform your rack into a sled. If you use the construction as a sled, we recommend using it on (artificial) grass or concrete, unfortunately, due to great resistance it won’t slide on rubber flooring. The package contains four carriers, a crossbar (carry bar) and two safety pins.
