Black Iron

Top Definition

The strut used to hang acoustical tile is called Black iron. This is the "C" shaped, 1-1/2" black strut that is bolted to the concrete deck or wooden beams using CADDY® hangers to create a secure mounting point for the grid ceiling runners. When looking-up fittings for black iron, most catalogs, such as CADDY®, use the term Lathers Channel.
