The present invention is directed to a method of manufacturing a support fixture for securing thermal insulation, such as glass wool batts and the like, to air conduit ducts forming parts of heating and air conditioning systems. The device comprises a metal pin weldingly connected to a planar sheet metal blank, the rear surface of the blank carrying a double faced adhesive tape, the rear surface of which is adapted to be adhesively connected to a duct. In accordance with the method of making the fixture, an improved adhesive connection is obtained between the sheet metal member and the adhesive tape by applying the tape to the blank while the blank is hot as a result of effecting the welded connection between the blank and the pin.
