The Grill-A-Pizza system kit comes complete with all prestamped and formed stainless steel parts engineered for perfect fit. Including the rotisserie motor, motor bracket, firewall, hub and axle assembly, and support brackets with all hardware bags clearly marked. You’ll find a complete set of installation instructions with pictorials showing each step of the way to the complete unit. There are NO alterations to your Weber kettle as the parts will attach to the existing kettle components. Example: The firewall mounts to the lower charcoal wire frame, the motor bracket attached to the kettle legs and the grill shroud simple sits on the kettle rim, what could be easier? NO DRILLING of any kind needed. We even supply the tools to make sure everything is properly assembled and secure. The Pizza stone (shipped separately) is also included and simply sits on the rotation platform. It arrives in a 6” x 9” x 22” carton carefully packed and ready to be assembled. Get it this morning and have great pizza a couple of hours later!
