The Gasmate Military Storage Boxes are built tough. They've been tested to withstand a 2 meter drop test and a pull test where units were loaded with 145kg's and dragged by one handle. Made from quality materials, the storage boxes feature 5mm polyethylene plastic case, 304 grade stainless steel lockable swivel hinges and handles, and handles are covered with polypropylene grips for comfort. Clever design features include tie down indent points moulded into the lid to enable effective tie down on utes, trailers and roof racks and storage boxes have two wheels on the two larger models to make them easy to move and transport. The Military Spec Storage Box series are perfect for storing camping gear and tools, and for use whilst on 4WD'ing, camping, hunting and boating trips.
