ABSTRACT:
A U-shaped hook device has a tensioned sock line attached to its bight portion while a helicopter haul line is removably connected to a first end of the device. The haul line is aerially pulled past a first pole of a tower until the device hooks onto the pole. The haul line is then moved to engage the second end of the device so that the haul line becomes positioned in a central opening between the first pole and a second pole. The helicopter unhooks the device from the first pole for passage through the opening thereby enabling the sock line to be mounted to an otherwise inaccessible center stringing block.
