Marketing InformationInsulation hangers are 12 ga steel insulation pins that are permanently staked through 2 x 2 in galvanized steel base plates. A pressure sensitive adhesive backing provides a permanent bond between the insulation hanger and ductwork. Each case includes self locking companion clips. Insulation Hangers also have 2 clearance holes in the baseplate that allow further reinforcement with a #8 self-tapping screw when needed. They can be used to hold all low and medium density insulation and insulation board where the temperature will not exceed 150 deg F.
