4. Pulling Grip Selection and Preparation
4.1 Prior to installation, the proper size grip must be
chosen for the cable to be pulled. Grip selection is based
on cable diameter. Generally speaking, use the smallest
grip which will fit over the cable sheath without excessive
difficulty. Measure the cable outside diameter and
determine the proper grip by locating the cable diameter in
Table 1.
Table 1
4.2 Once the proper grip is obtained, inspect it for
damage broken wires, bulges due to stress, rust, etc. After
putting on a pair of gloves, grasp the pulling eye in one
hand and smooth out the mesh with the other hand,
tightening the wires. Figure 2 illustrates the technique,
which is critical when re-using grips.
Figure 2
5. Pulling Grip Installation
5.1 Trim the end of the cable with side cutters
to remove any protruding tubes, yarn, or central member
(Figure 3).
Figure 3
5.2 To install the grip:
a) Slide the pulling grip over the end of the cable.
b) Use a pumping action to “walk” the grip over the
sheath by bringing your hands together and then
relaxing them until the end of the cable reaches 6 to
13 mm (0.25 - 0.5 in.) beyond the top of the mesh
(Figure 4).
Figure 4
c) Smooth the mesh back over the cable, moving from
the pulling eye to the cable sheath. Tug lightly on the
grip to tighten the mesh.
5.3 Starting at least 2.5 cm (1.0 inch ) below the mesh on
the cable, wrap vinyl tape TIGHTLY to the top of the
grip. Each wrap of tape should overlap the previous wrap by one-
quarter to one-half the tape width.The mesh’s imprint should
show clearly through the tape (Figure 5). The tape must be
tight to help compress the mesh against the cable. Tug on the
grip slightly to tighten the tape.
NOTE: If two or more vinyl tape layers are desired, always
wrap the final, outside layer from the cable sheath to the pulling
eye. This layers the tape like roofing shingles, so that it will not
snag as it moves through a duct.
