MW’s Australian-made custom truck under-tray aluminium toolboxes are engineered to maximise storage space on trucks, service bodies and commercial vehicles. Designed to mount beneath the tray or body, these heavy-duty toolboxes transform unused chassis space into secure, weather-resistant storage for tools, recovery equipment, chains, straps and work essentials without reducing tray capacity. Built from premium marine-grade aluminium, every toolbox is custom-made to suit your truck and application, with a choice of sizes, door configurations and internal storage layouts to meet the demands of transport, construction, mining, agriculture and fleet operations.
