ABSTRACT:
In a furnace insulating module, a plurality of heating element supports are embedded in situ in a ceramic fiber insulating body. Each support includes a rod with one end embedded in the insulating body. The rod is anchored to the insulating body by means of a cross pin welded to its embedded end. An element supporting keeper at the exposed end of the support rod is pivotable about a transverse pivot axis. The keeper is formed of a pin passing through the rod and bent to form fingers at both ends extending in opposite directions from the pivot axis. When the keeper is in a first position the fingers extend vertically, generally parallel to the support rod, and permit a rod overbend heating element to be moved along the rod to a position above the keeper. With the keeper then moved to a second position with the fingers in a horizontal plane, the heating element may be rested on the keeper fingers and be supported thereby.
