The latest Kennedy metal products overcast structure design is lighter and easier to build without compromising strenght or safety. Instead of using our standard stopping panels or masonry blocks for the sides of the overcast tunnel, we designed special interlocking side panels of any even length or width that lock to overcast decks and to themselves without using loose fasteners
or special tools. The only tool that is need is a crow bar.
Button head rivets welded to the mouning plate on top of the side walls sit in slots on the bottom of the overcast desk. As the deck is slid laterally into place, the rivet heads line up on the incline plane, and lock it rigidly to the wall creating a solid, airtight ventilation structure.
