Blank Duct Plugs


Blank duct plugs effectively seal conduits to reduce the cost of cable placement and
maintenance in new underground construction projects and routine work. These plugs are
economical because they are removable and reusable.

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.

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 future
use.• All plastic construction

• Corrosion proof
