Product Description

This blqd® mechanical blank duct plug is 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

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.
