The Cover-Mount Rack allows for hauling ladders, lumber or other long objects. It installs on top of the DiamondBack. This rack is great for the occasional overhead hauling and has a load rating of 350 lbs. Mount one pair of uprights at the rear of your cover, then put another pair up front or use the HD Cab Guard.
When using the Cover-Mount Rack with the HD Cab Guard, longer items that extend over the roof of the cab will need to be hauled at an angle. This will involve cutting down the height of the Cover-Mount Rack so it's lower than the HD Cab Guard.
