Product #122-S 4BU: Size isn’t everything. Although our Small Trucks might not be able to fit as much as some of our larger trucks, they are made with the same steel frame, tough steeletex bodies, with flat steel along the bottom for added support and come on 2″ non-marking TPR stem casters. For such solidly built trucks, they are surprisingly light weight and are just as at home hauling around tools and debris as they are toys and laundry.
