A slotted M-shaped support track structure and method in which a M-shaped support track having a planar web and U-shaped flange members and a plurality of slotted openings spaced lengthwise is mounted on the underside of a beam or other overhead building support structure. The plurality of elongated slotted openings are spaced lengthwise and defined by the planar web and adjacent inner legs of the rectangular flange members, and receive perpendicularly related vertical stud members, and thereby allow relative vertical movement between the M-support track and the vertical studs, while holding the studs in place horizontally.
