By using existing holes in reinforced sections of the wall, the Model 975401-3-01 Van Shelf Unit Mounting Kit makes it easy to install van shelving to house tools and other cargo van accessories. This commercial van shelving installation kit is compatible with the Chevrolet low-roof Express 135in wheelbase van. Its extruded aluminum upper mounting rail distributes weight evenly while providing flexibility in mounting locations. The absence of a floor-mounted rail allows for storage of wide, bulky work van accessories beneath the unit.
