hold within a distance of approximately 1 in. (2.54 cm). If the climber gaff slides
along the wood without digging in, or merely leaves a mark or groove in the wood
as shown in figure below, the gaff is either not properly sharpened and shaped or
the gaff angle is too small. The gaff angle is built into the climber by the
manufacturer and should be between 11 and 17 degrees with the climber placed
parallel to the surface of the wood.
POLE CUT OUT TEST ACCORDING TO ASTM F887 (Fig 4 )
This test shall be performed on a section of a treated pole in an area that is free
from knots and checks. Place the climber on your leg holding the sleeve with your
hand. With your leg at an approximate 30° angle to the pole and your foot about 12
in. (30.5 cm) off the ground. Lightly jab the gaff into the pole to a depth of
approximately 1/4 in. (6.4 mm). Keep enough pressure on the stirrup to keep the
gaff in the pole but not so much as to cause the gaff to penetrate any deeper. See
figure below. Push the climber and your hand closer to the pole by moving your
knee until the strap loop of the climber sleeve is against the pole. Make certain the
strap loop is held against the pole with pressure from your leg. Gradually exert full
pressure of your foot straight down on the stirrup without raising your other foot off
the floor or ground, so as to maintain balance if the gaff does not hold. See figure
below. The tip of the gaff shall cut into the wood and hold (dig itself in) in a distance
of not more than 2 in. (5.1 cm), measured from the point of gaff entry into the pole
to the bottom of the cut on the pole surface.
