04 / The practical details
Questions about aluminium ute toolboxes.
Are the boxes waterproof?
They are weather-sealed: fully seam welded with a rubber lid seal and drip channels, which keeps rain and road spray out in normal use. No box is fully submersible.
Can you match my existing tray or canopy?
Yes. We build to the space between the headboard, the wheel arch and the tray edge, so the box sits flush and the doors clear everything around them.
Do you fit them?
Yes. Boxes are bolted to the tray with backing plates and sealed. Fitting is usually done the same day as pickup.
