Will this fit my truck bed without drilling?

Crossover boxes are designed to mount across the bed rails at standard crossover points. Test-fit before committing to your mounting method — some trucks have slight rail variations that may require shims or adjustments.

Does the lock work with wet gear or salt exposure?

Aluminum resists corrosion well, but the lock mechanism itself isn't sealed against saltwater spray. Rinse the lock after heavy salt exposure to prevent freeze-up in cold climates.

What do I need to bolt this down?

You'll need fasteners appropriate for your truck's bed rails — these typically aren't included with crossover boxes. Measure your mounting points and grab Grade 5 bolts and lock washers rated for your truck's load capacity.
