To install, staple the loop fabric (included in Starter kits) onto the underside of the top shelf. Drop the rifle rod down the barrel of the long gun, set the stock in place and pull the rifle rod up until the VelcroTM attaches to the loop fabric. Rifle rods will stabilize your gun in the upright position. Continue this process until the safe is "straightened up". rifle rods are very versatile, so feel free to be creative when placing guns.
