Duct Plugs

RMC Plastics’ Duct Plug line is size specific and comes in 2”, 3”, 4”, 5”, and 6” diameters. These plugs are used for temporarily closing off electrical conduit until the system has been safely prepared for wire installation.

Molded from LDPE (Low Density Polyethylene), these plugs provide an excellent seal for the conduit thanks to both the generous tapering of their sides and the softer material being used in their construction.
