The Original Pilot Line Controller System was designed for stringing pulling lines for overhead distribution. It consists of a positive braking controller and a storage reel for rope which mounts on the lead pole at any desired height.
Once the controllers and storage reels are mounted on the lead pole, the lineman takes the pilot lines up with him and lays them in the stringing blocks as he frames each pole. After these lines are pulled out, they can be tied off under tension and left until time for stringing the conductor.
