GMP's 88268 detectable duct rod is used to find, follow and accurately map the duct route without digging or trenching. The traceable duct rod is used in conjunction with both a signal transmitter and a receiver. The easily identifiable signal is transmitted along the entire length of the duct rod.
The toneable duct rod has an 18 AWG copper wire, almost twice the size of the competition, in the center of the fiberglass core. The copper wire is also connected to the end fittings so the transmitter leads can make a direct connection to the copper wire. The female end fitting provides the attachment point for the transmitter
