ci Prong Washer

1-3/4″ diameter, white washer with keyholes. Prongs enable pre-spotting into insulation for easy on-the-wall fastener assembly.

Use with Grip-Deck® screws/fasteners to attach rigid insulation over a primary air barrier. Suitable for all types of insulation including extruded polystyrene (XPS), polyisocyanurate (polyiso), expanded polystyrene (EPS), mineral/rock wool, etc.

*For applications where rigid insulation is being attached and installed as the air barrier, use 2″ diameter Thermal-Grip® ci Prong washers for superior air barrier performance.
