measure clearance for telephone line from the road or a specific object.

tubing of various diameters and lengths, These sections, regardless of
the length to which they extend, are arranged in a telescopic manner so
that they may be collapsed into the bottom fivefold section for easy handling.
poles must withstand 100,000 volts without leakage to the handler.
poles are marked in feet and inches and extend to 25 feet.
