The Buyers Products XD Series of heavy duty underbody aluminum toolboxes are two-door barn style boxes constructed of 1/8" thick aluminum with an extruded aluminum front frame for durability. The extrusion is designed with a rain gutter to help channel water away from the interior of the box. The automotive bulb seal gasket seals provide weather resistance. With heavy duty, bolt-on stainless steel hinges with 1/4" pins, the boxes secure contents with a die-cast, three-point latch system with a built-in compression roller. The XD Series is available in several different sizes.
