ABSTRACT:
A gangable wireway assembly including a plurality of generally U-shaped troughs and trough covers utilized as either tandem sections or as fittings which connect the tandem sections in an elbow, tee or cross configuration. Trough covers have upstanding lips at opposite ends and drip hood flanges running along longitudinal margins which overlap flanges on the U-shaped trough. The tandem section covers include a reverse bend on one drip hood flange to interlock one margin of the cover with the trough. Adjacent trough ends are nestingly received by a connector and adjacent trough covers are overlapped by a connector cover at the juncture of adjacent cover sections. The connector cover includes a recess receiving the lips of adjacent covers and includes flanges in overlapping relationship with the drip hood flanges. One flange on the connector cover also includes a reverse bend to interlock with the associated drip hood flanges. Also provided is a generally U-shaped panel adapter and cover having opposite open ends, one of which includes outwardly directed flanges for sandwiching a gasket against a cabinet wall having an opening though which wires may extend from the wireway to the cabinet. A generally U-shaped closing plate having one open end and an opposite closed end is utilized to close a trough end.
