Duro Dyne Dur FTC34 Econo-point Duct Liner Pins

Product Description

The DURO DYNE DUR FTC34 is a box of 3/4-inch Econo-Point pins designed for securing 1-inch duct liner insulation inside sheet metal ductwork. These 30-gauge galvanized steel pins are driven or welded through the duct liner to hold the insulation firmly against the duct wall, preventing separation and maintaining airflow efficiency. Manufactured in the USA, these pins are a standard fastening solution on residential and light commercial HVAC duct lining jobs. The silver-finish steel construction provides durability in the typical interior duct environment.

These pins are suited for new construction and retrofit duct liner installations where 1-inch flexible or rigid fiberglass duct liner is being applied to the interior of sheet metal ductwork. HVAC sheet metal mechanics and duct installers use Econo-Point pins as a quick, cost-effective method to mechanically fasten insulation before applying adhesive or as a standalone fastener depending on the job spec. The box ships at 36 pounds, making it appropriate for job-site stocking on larger duct fabrication and installation projects.
