Abstract: An electrical resistance heating assembly having specially designed electrical insulators is disclosed. The electrical insulators have arms shaped to retain an electrical resistance heating coil which can be quickly, easily, and reliably mounted on the arms of the insulator. Top parts of the arms are generally rectangular or triangular in cross section and the arms are spaced and configured relative to each other to form a generally T-shaped opening between the arms, with the ends of the cross bar of the T-shaped opening forming electrically resistance heating coil retention surfaces. Also, cuts in side surfaces of the insulators may provide additional coil retention surfaces.
