The Ironman 4×4 Atlas Platform Racks are constructed of extruded aluminium beams, secured within an extruded aluminium perimeter. The racks are designed with the beams running perpendicular to the vehicle (side to side, rather than front to back). This setup makes for easier loading and securing of cargo, with far less chance of longer items dropping down and hitting your roof. A platform kit, including all mounting hardware, weighs between 24kg and 39kg. It is imperative that you subtract these total weights from the total roof load limit outlined by your vehicle’s manufacturer!
