ABSTRACT:
A slotted upper track (10) has double-thick sidewalls (34, 36and40, 42) through which the slots (54, 50and52, 56) extend. The sidewalls (34, 36and40, 42) and an interconnecting web (38) form a central channel in which upper end portions of the studs (12) are received. The upper track or header (10) includes secondary channels outwardly of the central channel that are formed by the flanges of the central channel (34, 36and40, 42) and auxiliary flanges (30, 46) and auxiliary webs (32, 44). The header or upper track (10) is of a one-piece construction, making it relatively economically to construct. Upper end portions of wallboard panels (WP) are positioned outwardly of the sidewalls (34, 36and40, 42) of the central channel. Trim panels (TP) of wallboard are connected to the auxiliary flanges (30, 46) and are positioned laterally outwardly of the upper end portions of the main wallboard panels (WP). The trim panels (TP) will move with the header or upper track (10) and the main wallboard panels (WP) will move with the studs (12).
