A steerable head 11 is described for guiding a pusher rod 10 through ducting. The pusher rod 10 is then used for drawing cables, wires, lines or pipes through the ducting. The steerable head 11 includes remotely operable mechanisms for steering the rod 10 through junctions or around obstacles in the ducting. In a further refinement, the steerable head 11 is provided with a coupling means 36 adapted to co-operate with a corresponding coupling means 26 mounted on a second rod, thereby allowing the pushing of rods through longer or more obstructed ducts.
