Boximus 900mm Flat Aluminium Under Tray Toolbox
Whether you're on-site or off-road, having the right storage makes all the difference. The Boximus 900mm Flat Plate Aluminium Under Tray Toolboxes give you secure, lightweight storage without eating up tray space. Designed to bolt straight under your Ute or truck tray, these boxes keep your essential tools locked away, dust-free, and ready for the next job — or the next track.
Crafted from 2mm flat plate aluminium, they’re made to handle hard knocks without rusting, denting, or peeling. The clean finish wipes down easy, and the compact design means you can kit out both sides of your rig for maximum efficiency.
With drop-down doors and whale tail locks, your tools stay secure even when you're not around. Inside, you’ve got enough space for everyday hand tools, recovery gear, tie-downs, ropes, and more. No more rattling around in your tray or scrambling to find what you need.
These boxes are built to match your tray profile perfectly, so they don’t just work well — they look sharp too. They are lightweight without compromising strength, making installation a quick DIY job for anyone handy with a spanner.
Need more gear for your setup? Explore the Boximus range of aluminium toolboxes, steel boxes, trundle drawers, and whale tail locks — all designed for folks who need function, not fluff.
