Self-Stick Insulation Pins 3-1/2 (100Pcs) with Self-Locking Washer(100pcs) Made in USA

Self-Sticking Insulation Hangers are used to fasten insulation materials to sheet metal quickly and easily. The most common application is for fiberglass duct wrap on sheet metal HVAC ductwork. Each pin's metal base has a foam adhesive on the bottom which is revealed when the wax release paper is removed. Once the insulation is pierced onto the pin, a locking washer or a domed cap can be installed to hold the insulation in place. RESTRICTIONS: Do not use on metal buildings or ceilings where temperatures due to sunlight exposure may exceed 140ºF. Do not use on cement, wood, or painted surfaces Must be used on clean dust-free surfaces. Do not exceed spacing of 12" between hangers and 2 lb load per hanger.

• Insulation pins are driven into a surface to secure insulation materials, while self-locking washers are placed over the pins to distribute pressure and prevent the insulation from tearing. Together, they ensure the insulation stays securely in place and maintains its effectiveness over time.
