A fixture for heat treating furnaces is disclosed having a frame composed of horizontal round rods and horizontal rectangular bars and vertical rods with vertical tubular connector units having transverse slots through which the horizontal bars extend and openings normal to the bars through which the horizontal rods extend, the vertical rods being slotted at their ends to engage the horizontal bars. Wires are employed to hold the structure in assembled relation. Horizontally disposed work piece racks are supported by the horizontal bars. The components of the frames and racks are preferably of low specific heat material, and preferably of molybdenum but may be of tungsten, tantalum, columbium and their alloys, or of graphite.
