The RAM Tough-Tray is spring loaded expandable tray that can accommodate 10 to 16 inch wide laptops. The tray includes four side clamping arms with rubber grips to keep your laptop secure in any rugged environment. These arms can be moved both vertically and horizontally, allowing a custom fit for varying thicknesses of laptops and the freedom of not blocking ports or drives. Hole patterns on perimeter of tray facilitate the mounting of additional RAM systems to support GPS, PDAs or other electronics.
