blqd® expanding duct plugs play a crucial role in maintaining the integrity of ductwork in various industries. They are used to create a secure and reliable seal in ducts or conduits, which helps prevent environmental factors such as sewage and dust ingress from entering the duct.
The expanding duct plugs are used to seal a open pipe-end again the sewage and dust ingress.
Manufactured from high-impact plastic components, combined with durable elastic
gaskets, Blank plugs are corrosion proof and effective as long-term or temporary seals.
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.
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.
