The purpose of the detectable rod is to have the ability to accurately find existing underground ducting or to locate the position of a blockage within a duct.


Ruf Rod Detectable Duct Rodders are available in 5/16″ and 7/16″ diameter rods; they are available in 200′ to 1,000′ lengths.

Each detectable Ruf Rod unit is provided with a terminal box mounted on the frame with male and feminine banana terminals for external hook up. Each sizes of rod have #22 gauge copper wire down the middle of the fiberglass core.

It’s endorsed that a Roller Information all the time be used in order to maximize the connection between the tip of the rod and the wall of the ducting. This is critical so as to complete the circuit again to the earth for locating.
