Motomaster SE Roof Top Box. Made from lightweight polypropylene in an aerodynamic wedge design. The outside dimensions are 36" wide x 50" long x 19" tall. This versatile box can be mounted directly on the roof, or on existing roof-racks (via U-bolts that are not included). As seen in picture #7, the underside of the box is fitted with foam padding, to prevent scratching. It also comes with four cinching straps with catches (picture #8). Used, but in good condition.
