We call this item our “Strong Boy”. Because, yeah, this is one strong cart! Suitable for both a 30 or 40 truss, the base of this powerhouse is made of strong steel. The Strong Boy is zinc coated to withstand the test of time and equipped with rubber studs for the optimal friction of your truss. From now on, shifting trusses are a thing of the past. As an extra, hooks can be applied on each side of the dolly to secure the load. Our prediction: Strong Boy is a winner!
