Box of 100 Duro Dyne 1-1/4" Dynastick Self Adhesive Insulation Fastener Hangers (# SAH114)

SAH Dynastick is an insulation hanger with a self-stick base. Just peel the release paper from the hanger base and firmly press the base to the clean duct surface. Impale the insulation over the hanger nail and slip on the locking washer. Self-stick hangers adhere to clean metal surfaces and withstand temperatures of up to 175°F. When liner is placed inside air conditioning or heating duct work, the movement of air could cause the insulation to delaminate. To prevent this, SMACNA specifications call for the use of fasteners in addition to adhesive to secure the liner. When using an adhesive fastener, the fastener is bonded to the ductwork with an appropriate adhesive and allowed to set up. After sufficient drying time the liner is impaled on the pin and a washer added to retain the liner.
