摘要:
An assembly for use by a surveyor having a ruler and an apparatus for securing the ruler to a surveyor's pole. The ruler has a retractable tape and a belt clip. The apparatus for securing the ruler to a pole includes a cradle sized to retain the ruler, a stop member, a planar wall member and attachment members for securing the apparatus to a pole. By securing the ruler to a pole, a single person may complete measurements which previously required two people. The tape of the ruler includes measurements which are inverted with respect to the tenth of a foot for easier reading.
