Abstract: A building panel offset adjustment and leveling system permits precise mounting of panel extrusion channels, and thereby the panels, onto the surface of a building. In a particular embodiment, a slotted spool race along the under surface of each extrusion channel mates with a threaded spool having a first flange slidably received within the spool race and a second flange coupled to the first flange by a threaded collar. The second flange articulates between a proximate position closest to the race and a distal position, providing a continuous offset adjustment range between said extrusion channel and the building. In one or more alternate embodiments, columns of coaxially mated shims replace the spool and provide incremental, graded offset adjustment. In each embodiment, a hollow bore through the offset adjustment system accepts a fastener which affixes the extrusion channel to the building and clamps the adjustment system into its selected offset position.
