Easy to install - place the liner over the sheet metal and drive the banger through the insulation. Upon impact, the jaws of the fastener penetrates the metal and locks securely within the thickness of the metal itself. (Always place a hardened steel block behind the sheet metal at the point of impact). Bangers can be installed with model DHH Double Headed Hammer or AB-5 Automatic Banger Setter.
