ABSTRACT:
A hanger fitting usually made of metal includes two spaced, substantially parallel and planar rigid portions joined by at least two transverse portions. The planar portions have a first pair of threaded apertures formed generally perpendicular to the planes adapted to be engaged by a first corresponding pair of set screws for engaging a tongue or other member to which it is to be mounted. The transverse portions include a second pair of threaded apertures disposed generally transverse to the first pair and being adapted to be engaged by a second corresponding pair of set screws. Both pairs of set screws engage the tongue to which the fitting is to be mounted thereby to prevent movement of the fitting with respect to said member in two mutually perpendicular directions. The parallel portions also have a lower part adapted to be coupled to a signal assembly, or the like. In one form the lower part includes two lower rigid spaced, parallel portions having aligned transverse apertures; in another it includes a threaded nipple for directly engaging an aperture in the housing of the signal assembly itself.
