Why is this unit in the DiamondBack Outlet? This DiamondBack HD has scratches and tooling marks on the underside of the cover. The mid panel gutters are not textured and have a shiny appearance. There are spots on the underside of the cover that the weatherstrip is compressed. This is purely cosmetic and will not affect function. All DiamondBack Outlet items carry the same lifetime warranty as regular DiamondBack items.
