This 6418 Porta Truer Stand adjustable machine stand works with our 405w Porta Truer and gives your customer the best of both worlds- true the tire on the vehicle, or set the truer on the portable stand and true the tire while it is mounted on a spin balancer. The newly designed adjustment feature allows you to “Set It and Forget It”. Now you can true tires of varying diameter without readjusting the stand.
