ABSTRACT:
A support assembly for an open coil heating element including a planar mounting plate having longitudinally spaced and offset cutouts therethrough with a separate insulator positioned within each cutout by sequentially introducing the insulator through the cutout and longitudinally shifting the insulator within the cutout to overlie the upper and lower surfaces of the mounting plate. The two insulators are locked within their mounted positions within the cutouts by a locking frame affixed to the mounting plate and abutting against the insulators to preclude movement of the insulators from their mounted positions.
