Security & Weatherproofing

Taking the time to lay down a few strips of adhesive automotive weather stripping or some other type of adhesive rubber strip will create a water-tight seal if you wish.

We love how it is mounted below the bed rails so that it’s easy to cover up with a tonneau cover. truck tool box plasticIt also adds some great storage if you use a canopy without losing space on the floor of your bed. The lockable latches make it a legal gun case which would make it a great addition to your hunting rig. One drawback is that it is a little bit small, and is definitely not as big as some of the other metal tool boxes we have reviewed in the past. You could always get another one and mount it on the other bed rail. Overall this is a great affordable option.
