RAM's four-inch step riser in die cast aluminum is included, or can be ordered with, many RAM laptop vehicle mounting systems to adjust their height. Form and function are similar to the older steel version; however, this new model sports a lighter weight. Featuring softer lines and more attractive curves, this new die cast riser is all about performance without a sacrifice in quality or durability. It measures 8.5 x 3.8 x 4 inches and weighs 1.3 pounds.
