Transport Kits are not for over the road use. Transportation Kits consist of two wheels, slide-in axles, a tongue, a jack, and hardware. Transportation Kits only work with transportable dura-lite welded bleachers. Wondering which transportation kit you need? Match the length of the transportation kit with the length of the bleacher to be transported. One transport kit will transport multiple bleachers multiple kits are only needed if you desire to move more than one bleacher at a time.
