In a furnace for heat treating workpieces, a combination comprising an elongated internally-cooled supporting member for supporting workpieces which are to be advanced through the furnace;
- and a plurality of workpiece-engaging elements of one-piece constructions each having a lower portion mounted on said supporting member and an upper portion having an upwardly-directed planar surface which is adapted to support the workpieces from below, said lower portion having a smaller cross-section than said upper portion, wherein said supporting member has a side facing said lower portions of said elements, and wherein each of said lower portions has a mounting face in surface engagement with said side of said supporting member wherein said lower portion has a pair of spaced sidewalls which diverge away from each other in direction from said lower portion towards said upwardly-directed planar surface of said upper portion.
