The platform is made of two of what we call “pontoons”, plus bridges between pontoons and ramps to get up onto them. The pontoons are constructed entirely of rivetted and bonded top grade aluminum which because of its high alloy content is very stiff and tough. The endcaps on the pontoons are polished 316 stainless steel for its durability and good looks. Each 2″ high pontoon weighs 55 lbs. The vendor supplied levelling feet are cadmium plated 5/8″ unc thread with 2″ swivel bases and socket drive tops. There are six levelling feet per pontoon. The platform has been designed to accept a wide variety of forumula cars with no appreciable deflection or distortion.
