The Alu-Box Aluminum Storage Case ABS20 is the perfect solution to storing your valuable equipment. It is the combination of a precision bent aluminum ribbed wall, with an extruded base and upper rim, and a lid protected by heavy duty cast aluminum corners that put this case ahead of the competition. Dust and water resistant, and stackable. They are the choice of Overlanders for storage inside or out. This is the smallest case in the Alu-Box line.
