General Machine Products 84850 C Pull Finder with Case - Manual (Page 2)

To Bisect Angle
The C Pull Finder, in addition to determining
the pull on a corner pole can also be used to
provide a quick, convenient method for bisect-
ing the angle of the corner pull for the purpose
of locating the anchor or stub pole. To bisect
the angle, proceed as follows:
a.
Mount the Pull Finder on the corner pole
and measure the pull in feet, as described
on the reverse side.
b. Without disturbing arm B swing arm C
away from the pole until the bisector index
(located just beyond the 40 foot mark on
the pull scale) points to the pull reading
(obtained in (a) above) as read on the
corner bisector scale on arm B (figure 3).
c. Arm C is now in line with the bisector of
the corner angle and the anchor or guy
stub should be located in line with the
back sight and the front sight on arm C. If
the anchor or guy stub location is so far
away from the pole where the Pull Finder
sights may be easily observed. The an-
chor or stub may then be located in line
with this marker and the corner pole.
