Expanding Duct Plugs effectively seal conduits to reduce the cost of cable placement and maintenance in new underground construction projects and routine work. These 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. ● High-impact plastic components, combined with durable elastic gaskets ● Corrosion proof and effective as long-term or temporary seals ● Water-tight and gas-tight ● Equipped with a rope tie device to allow the securing of pull rope to the plug's back compression plate ● Removable and reusable
