Quilting pins simplify the permanent installation of “Duct Liner” or other insulation materials by securing this insulation to duct work or to other heating, ventilating or air conditioning sheet metal configurations and housings.

They are made up of a weld pin and a staked on retaining washer. This product is usually applied with a capacitor discharge stud welder. It can also be used as a hookless lacing anchor to secure insulation inside fabricated blankets. The pins are accepted as labor saving fasteners in the thermal and acoustical insulation markets for use in industrial and commercial applications.
