Abstract
A barbecue grill cart assembly is provided having a unique leg locking system at each corner. The locking system provides a plurality of contact points for each leg to obviate any swaying or twisting of the legs. The lower shelf includes extruded bolt receiving apertures which mate with corresponding apertures in the legs. The side shelves have a locking system including elongated slots which provide positive engagement and prevent accidental lowering of the shelves.
