Abstract
Abstract A support for an electrical fixture from a ceiling tile or ceiling wall structure of low tensile strength, comprising a junction box fitted between load spreading beams positioned to overlie the structure. A pair of bendable hanger straps are hooked over the beams and flank the box which is held with its lower edge flush with the ceiling surface. The straps are bent at their lower ends upwardly into the box under its lower edge, and thus hold the box with its lower edge aligned with the ceiling surface. A clamping foot is mounted on each hanger and presses against the top of the tile, and the box has big extensions which bear against the bottom of the tile.
