ABSTRACT:
A structure is provided for supporting at least one heating element inside an electric heater housing. To produce the support structure, a web is cut out of a metal sheet that includes a rectangular member, one or more support brackets and a neck portion connecting each support bracket to one side of the rectangular member. The support rail is formed by bending the rectangular along its longitudinal median into an L-shape configuration with a first portion integrally formed with a second portion in a perpendicular relationship. The first portion is secured to the electric heater housing. The second portion extends inwardly in the electric heater housing. The neck portions extend inwardly from the second portion, and are twisted approximately 90.degree. with respect to the support rail. The support brackets extend inwardly from each neck portion. Each support bracket has one or more openings formed therein, each adapted to receive electrical insulating means, such as coil bushings. The heating elements are inserted through the insulating means to electrically isolate the heating element from the support bracket. Means also is provided for securing said insulating means within the opening of said support bracket.
