Insulation Fasteners Rib Pins

Econo Point FTC weld pins utilize a specially pointed nail to assure uniform welding. Duro Dyne Welding Rib Pins (CP) have dished washers, ribbed nails for faster cooling and precision points to assure uniform quality. BDEP and CTC pins have unique washers designed to improve the quilting contour of the insulation surface.
The needle sharp point enables the operator of the machine to easily push the weld pin through the insulation into firm electrical contact with the metal duct.
Welding current is supplied by activating the weld transformers. Current flowing through the pins point of contact creates instantaneous welds of extremely high strength.
