The Underbody Aluminum Dropdown Toolbox is another one of our popular products, especially because of how lightweight and corrosion resistant it is. We offer lots of different sizes to fit a wide variety of applications. We use robotically welded .125" aluminum diamond plate tread, commercial grade gaskets, steel cables for supporting the door, stainless steel huck on hinges, and an adjustable die-cast HD lockable T-handle to ensure we have the best box money can buy.
