Here’s the square /rectangular Forklift Loadable Rack with over cab protection. Its on a Ford SuperDuty Crew Cab with a sharp Harbor ComboMaster Service Body. See how the side rails are lower than the cross bars so that the load is supported and the forks can be easily retracted. It has removable / swing-away cross bars. Notice that it has no posts in the way of the work area even though it still extends to the rear end. The 36" platform floor extension provides a great hip-level work area.
