Abstract: A side utility rack and rack kit for trucks having a pipe carrying rack or similar bed-mounted racks employs an assortment of brackets useful with conventional pipe cut in desired lengths in construction. The side utility rack is hung by means of hook brackets from a tubular member of the pipe rack and rests against the truck bed wall at a lower end inner bracket having a rubber bumper to avoid damage to the truck bed. The rack forms forward and rear cages separated by a lengthwise pipe member. The cages accept large, flat objects such as drywall panels or plywood supporting them for safe transportation. The cages may be adjusted in spacing to fit a particular truck and rack and for carrying particular lengths of flat cargo. The rack may be differently configured to fit differing racks associated with pickup or utility trucks.
