This is a great way to keep your gear safe and covered up away from prying eyes. This rear deck cover is constructed out of 1/8" aluminum and comes powder coated black. I supply the screws to put the cargo cover together. You'll use your hard top bolts to mount it to the jeep, "I can supply the six exterior bolts w/ nuts to mount the cover down for a extra charge". It is desinged to work with both tops, on or off. I have a "6 piece tie down rail kit" that you can add to the top of your cover. This option creates tie down points so you can strap down gear to the top of your cover. You also have tie down points on the underneath side of the panel to strap gear to also. It ships free within the USA.
