Description

The RKI ST-Series Double Lid Aluminum Crossbox, model ST63A, is a crossover truck tool box designed for full-size trucks. It features twin gull-wing type lids that operate independently. The hull and lids are constructed from durable .080 bright diamond treadplate aluminum, with a .125 smooth aluminum bottom. The lids have inner stiffeners made of .090 smooth aluminum, and all welds are full arc welds for increased strength. Each lid is attached with two 4" aluminum butt hinges with 1/4" hinge pins, which are welded to the box and lid. The box is equipped with full-size stainless steel paddle latches, gas shocks for easy one-hand opening, and ribbed D-bulb seals to protect contents from the elements. It includes a sliding tray (29.25" x 19.25" x 2.375") with four adjustable dividers, supported by tracks and tray stops to keep it centered when not in use. The mounting hardware consists of an extruded aluminum clamp that eliminates the need for drilling through the truck bed rail, and a plastic isolator prevents paint scratching and galvanic corrosion.
