Duct Liner Pins are widely used to fasten insulation materials onto steel duct work or other steel surfaces. Used with a duct liner pin welder, the duct liner pins are directly welded to the metal after they pierce through the insulaton and make contact with the metal surface. It save a lot labor cost for the fiberglass insulation ductwork.
Duct Liner Pins have a paper washer or can be plastic coated to prevent sparking.
