Abstract: An adjustable hanging support mechanism for a folding panel assembly enclosure which comprises a plurality of folding panels and end posts secured thereto and which fold in an accordion fashion while being suspended by the support mechanism along a top end thereof. The hanging support mechanism has a support rod which is connected at a top end to a displaceable carriage which is engaged in a support rail. The support rod has a plurality of spaced fastener engaging apertures extending along a connecting section thereof. The apertures are configured to receive a fastener element in engagement therewith. At least some of the panels are provided with connecting cylinders to receive at least a connecting section of an associated one of the support rods in axial rotation therein. Fastener elements are associated with the connecting cylinders to permit interconnection with a selected one of the fastener engaging apertures of an associated support post to provide vertical height adjustment of the enclosure.
