How to choose the right box

1. Mounting style: Underbody vs. surface mount; confirm bracket type/size.

2. Material: Steel (maximum strength) vs. aluminum (lighter + corrosion-resistant).

3. Seal & latch: Look for compression latches, rain gutters, and D-bulb gaskets.

4. Access & service: Removable doors, continuous hinges, and cable stops save time.

5. Size & clearance: Measure width/height/depth and door swing around tanks, PTOs, and liftgates.

Installation & care tips

• Dry-fit first to confirm door swing and cable range.

• Use proper brackets (sold separately) and torque hardware to spec.

• Rinse after winter to remove salt; inspect gaskets quarterly.

• Touch-up chips to protect powder-coat and reduce corrosion risk.

FAQ: truck tool box

Steel or aluminum, what should I choose?
Steel maximizes strength. Aluminum is lighter and highly corrosion-resistant. Pick based on environment and payload needs.

Will I need mounting brackets?
Yes for underbody installs. We carry welded/bolted structural steel and formed C-channel options; aluminum sizes 1701030 and 1701040 are available.

How weather-tight are these boxes?
Each model uses compression latches, continuous hinges, and a gasket system designed to keep out water and grime.

Can I mount these on a flat surface instead of underbody?
Yes, many models allow surface mounting. Verify door clearance and hardware before drilling.

Do you stock multiple sizes and finishes?
Yes. If you don’t see a size listed, contact us for options and a quick quote.
