Hollow Pole Riggers
This device is used for threading cable up the inside of hollow telegraph poles. It is used by screwing the head on to Rod Duct No.2 and pushing it up the inside of the telegraph pole. A weight attached to a length of rope drops down the outside of the pole, leaving the pole threaded by rope. Cable can then be drawn up the inside of the pole. The rope and weight are not supplied with the Rigging Head 1A.
