Punch-Lok Bands are applied
over the tail of a grip to prevent the mesh from being tripped or
pulled loose. Also, they assure full gripping action by locking the
mesh of the tail in tight contact with the cable or rope.
When the tail of a grip is the leading end, the bands are
particularly important to prevent accidental release caused by
tripping on obstructions. A conductor-to-conductor (double-socking)
pulling operation is a good example: where two grips connect two
conductors to form a temporary splice. Bands should be applied to
the ends of the grips as illustrated herein. It is also common
practice to tape over the banded tail area to assure smooth passage
through the sheaves.
The conductor should be installed in the grip up to the elbows of
the aluminum shoulders in order to assure full and complete gripping
action. The banding procedure is then followed as illustrated on
page T-15.
Note: In all cases two Punch-Lok bands should be double
wrapped approximately one inch to two inches (2.54 cm. and 5.08 cm.)
from the grip's tail. Banding is required to ensure maximum
reliability and guard against accidental release.
