Boximus 900mm Black Steel Under Tray Toolbox No room in the tray? No worries. If you’re short on space up top but still need to haul the essentials, the Boximus 900mm Black Steel Under Tray Toolboxes have you covered. Designed to tuck neatly under your Ute or truck tray, these boxes are built tough to handle the harshest conditions — rain, dust, rocks, and rough roads. Made from 1.5mm thick powder-coated steel, these toolboxes are built to last and cop whatever the job (or the bush) throws at them. The black finish not only looks clean on any setup — it adds extra protection against rust, peeling, and wear. No flashy chrome, no gimmicks — just gear that gets the job done. Whether you’re a full-time tradie or chasing tracks through the outback, these underbody boxes offer secure, no-fuss storage for your go-to tools and parts. With drop-down front doors and whale compression locks, you get peace of mind your gear’s locked up tight when you're not around. The stainless-steel half barrel hinges and weather-sealed openings mean these boxes stay shut and dry — even when the road’s not. And with a sturdy, easy-grab handle, you’ll have no dramas accessing your kit on the go. Easy to mount and ready to roll, these under tray units save tray space and keep your gear safe, sorted, and always within reach. No fancy install required — just bolt it on, load it up, and get to work. Need more storage?
