What hardware do I need to mount this to my truck bed?

Mounting hardware and method are not specified — you'll want to verify bolt-down points on your bed before purchase to confirm you have compatible anchor holes or rails. Bring your truck bed dimensions and take a photo of the mounting surface to compare.

Will the aluminum need any prep or paint before I install it?

The silver finish comes ready to mount as-is. If you plan to paint it to match your truck, light scuff with 220-grit and use a primer formulated for aluminum to ensure paint adhesion.

Does the lock prevent the lid from being pried open?

The integrated lock secures the lid from opening — it's a deterrent for casual theft but not a heavy-duty security solution if someone brings tools. Treat it like a toolbox lock: it stops quick grab-and-go, not a determined attack.
