A Gripnail is a unique mechanical fastener used to attached insulation to sheet metal. It was specifically designed to fasten acoustical duct liner to the inside of heating, ventilating and air conditioning ductwork. This operation generally takes place when the ductwork is being manufactured.

PowerPoint weld pins are used to fasten insulation to the inside of sheet metal air ducts. These fasteners are usually applied when the ductwork is being fabricated. The fasteners have been specifically designed to work with all currently available duct liners and standard resistance welding type application equipment.

Now you can mechanically fasten insulation to pre-painted or powder-coated sheet metal with Insul-Tacks™ by Gripnail Corporation. This revolutionary fastener can be used as a primary means of attachment for insulation or to temporarily hold insulation in place while an adhesive is curing. In either case, the insulation is instantly held in place exactly where you want it, and there is no messy adhesive over spray to clean up.

EZ Hang insulation fasteners are available with pressure sensitive peel and stick backing material or with perforated bases for use with adhesive.
