Does this box come with mounting hardware or brackets?

The box itself is included with the lock. Mounting hardware for your specific truck bed or trailer is not confirmed — confirm your bed's tie-down points before purchase to ensure compatibility.

Can I use this on both a truck bed and a trailer?

Yes, the universal design works with standard truck and trailer mounting points. You'll need to verify that your vehicle has accessible tie-down locations where the box can be secured.

Will the aluminum rust or corrode?

Aluminum naturally resists rust and corrosion, so this box handles outdoor exposure without the maintenance steel would require. Over time, the surface may oxidize (turning dull gray), but structural integrity stays intact.
