		5/16" Diameter Detectable Duct Rodder 53700 series Catalog PDF Operating Instructions This 5/16" Ruf Rod Duct is one of the most popular sizes because of its versatility in both small and medium size ducts. It is the smallest of the wheel frames, yet still well under 3 ft. in height or length so easy to store or load onto your truck. Although DCD only recommends lengths up to 600 ft, the standard cage will hold up to 1000 ft. The longer lengths should only be used in smaller ducts (up to 2-1/2” dia) and when there are few bends.
EXTREME DANGER NEVER USE THIS DETECTABLE RODDER IN A LIVE ELECTRICAL ENVIRONMENT, ELECTRICAL SHOCK OR DEATH MAY RESULT IF CONDUCTIVE ROD TOUCHS EXPOSED CIRCUIT.

The Standard unit includes a Female Rod End, a Swivel Rod End and a Pulling Eye. The Deluxe version includes accessories as listed in the catalog PDF.

All accessories that attach to the rod can be glued on in the traditional manner or they can be clamped on with set screws or they can be glued and screwed for extra security.

The purpose of the Detectable rod is to be able to accurately locate existing ducting underground or to locate the position of a blockage within a duct.

Each DCD detectable Duct Rod unit is supplied with a terminal box mounted on the frame with male and female banana terminals for external hook up. Both sizes of rod have #22 Ga. copper wire down the center of the fiberglass core.

It is recommended that a Roller Guide always be used in order to better make the connection between the end of the rod and the wall of the ducting. This is necessary in order to complete the circuit back to earth.

Any transmitter can then be hooked up to the terminal box with the second lead from the transmitter going to ground (spike into earth). Once switched on, the signal will be transmitted along the duct rod and a standard locator can then be used to locate the signal source from above ground.

DCD Also offers Stainless Steel adapters with a 1/4" NC male thread for attaching a Sonde unit to the Swivel Rod End.


Caution should be exercised when ordering long lengths since the signal
diminishes with length traveled.
