GRIPNAIL POWER POINT WELD PINS
PowerPoint weld pins are used to fasten duct liner insulation to the inside of sheet metal air ducts. These fasteners are usually applied when the ductwork is being fabricated in sheet metal shops. The fasteners have been specifically designed to work with all currently available duct liners (usually fiberglass duct liner insulation) and standard resistance welding type application equipment.
Beveled Edge Cap
Prevents tearing of duct liner insulation
Forged diamond point design creates more electrical resistance for faster welds.
Zinc and Chromate plating exceeds SMACNA standards and gives a more professional appearance.
Reduced Down Time
Consistent point quality reduces frequency of machine adjustments.
Hardened steel point assures positive electrical contact for complete sheet to pin fusion.
Applied with Standard Equipment
Easily applied with Gripnail's Automatic Pin Welder or most standard hand held or hopper fed resistance welders.
Manufactured with pride in the USA
To the highest possible quality control standards.
