Low Profile Aluminum Boxes
Alum-Line’s Low Profile Aluminum Boxes are tool / storage boxes designed to mount on the side rails of a truck bed, running along the bed’s full length if desired, but with a lower height profile. Because they sit lower, they reduce visual obstruction, and offer a more streamlined look while still giving useful storage.
