Abstract
Abstract An electrical junction box having an indentation or groove on one side so that the box can be fitted over the ridges commonly found in typical roofing panels. Electrical conduit connecting holes in the box are positioned so that the conduit is directly in line with the edge of the ridges so as to avoid the necessity for bending the pipe. A spring clip in the groove on the box holds the electrical junction box in place on the ridge.
