The Gripple Corner Saddle is a right-angled reinforcement molding designed for positioning and supporting the Gripple Hanger on rectangular ductwork. It is a single piece molding that locates the wire rope diameters of Gripple Hanger sizes No. 1-3. The Corner Saddle locates the wire rope, provides additional strength at the bearing point of the Hanger, and prevents metal to metal contact being made. In most situations, any insulation that needs to be fitted to the ductwork can be wrapped easily around the duct as well as the Gripple Hanger and Corner Saddle. The small diameter of the wire rope allows the exit point through the insulation to be easily closed to ensure an airtight fit.
