              Product Description

              The expanding duct plugs are used to seal a open pipe-end again the sewage and dust ingress.

              Duct Bank Durability

              Manufactured from high-impact plastic components, combined with durable elastic

              gaskets, Blank plugs are corrosion proof and effective as long-term or temporary seals.

              Economy and Safety

              Both water-tight and gas-tight, Blank duct plugs prevent the flow of water and the costly

              sedimentation of duct banks and conduit systems while confining problems of dangerous

              vapors to their source.

              Convenience

              Each Blank plug is equipped with a rope tie device to allow the securing of pull rope to the

              plug’s back compression plate. Installers can attach the rope to the back compression plate

              of the plug and store excess slack rope behind the plug within the conduit system for futureuse.
