Cupped Head Capacitor Discharge Weld Pins are widely used for metal air duct insulation work.
The pins simplify the installation of "Duct Liner" or other insulation materials to duct work or to other heating, ventilating or air conditioning sheet metal configurations and housings.
Cupped Head Capacitor Discharge Weld Pins are widely accepted as labor saving fasteners in the thermal and acoustical insulation markets for use in industrial and commercial applications.
