In relation to the top of the pole, where should the bottom of a raked plumb bob line be positioned?

The bottom of a raked plumb bob line should be positioned directly in line with the top of the pole to ensure accurate measurements. This positioning allows for a clear and precise reference point when checking the vertical alignment of the pole. By aligning the plumb bob with the top of the pole, a lineman can ascertain whether the pole is perfectly upright or if it is leaning, which is crucial for safety and structural integrity. If the plumb bob were to be placed at a different point—like above the top of the pole or at the midway point—it would not provide the necessary reference for vertical alignment, leading to potential inaccuracies in pole installation or maintenance.
