Fish tape or wire-puller has been designed to put an electric wire into a conduit easily and is a tool that, if a electrical worker pushes the wire-puller into the conduit and connects the wire with the front terminal hole of the wire-puller coming out of the other side of the conduit before pulling the wire-puller, makes the wire pass rough the inside of the conduit.                                http://www.judin-line.com/
