ABSTRACT:
A suspension unit for installation in an openwork or grid-type suspension ceiling to support a fixture-hanging junction box, the invention comprises a one-piece strap-iron supporting bar which is adapted to bridge the space between a pair of conventional inverted T-irons. The respective outer end portions of the bar include right angularly positioned downwardly opening hooks which are hooked over the respectively cooperable T-irons and are held in place by accessible setscrews. The median portion of the bar is twisted to stand edgewise and serves to adjustably mount a hanger clip which is carried by the junction box.
