CORNING SST Instruction Manual

Figure 1
1. General
1.1 This procedure provides instructions for installing a
wire mesh pulling grip on Corning Cable Systems SST,
SST-Ribbon™, SST- ltraRibbon™, SST-Ribbon™ Dry-
Lock, ALTOS, and ALTOS Riser fiber optic cables
(Figure 1).
1.2 This procedure describes how to use a pulling grip to
couple the pulling load to a single-tube cable’s jacket.
Please read and understand this procedure completely before
starting the installation of a wire pulling grip.
1.3 This includes ALTOS And ALTOS Riser cables.
2. Precautions
2.1 General Precautions
2.2 Cable Handling Precautions
3. Tools and Materials
3.1 The following tools and materials are required to
complete this procedure:
• Kellems®pulling grip
• Side cutters *
• Measuring tape *
• Vinyl tape, 3/4 in (19.1 mm) *
• Gloves
• Scissors *
• Hex wrench or screwdriver* (to fit swivel)
• Swivel, ball-bearing type
*Items included in the M67-003 Tool it
4. Pulling Grip Installation
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.

Safety Glasses
WARNING: The wearing of safety glasses to
protect the eyes from accidental injury is strongly recommend-
ed when handling chemicals and cutting fiber. Pieces of glass
fiber are very sharp and can damage the cornea of the eye eas-
ily.
Safety Gloves
The wearing of safety gloves to protect your hands
from accidental injury when using sharp-bladed tools is
strongly recommended.
CAUTION: Fiber optic cable is sensitive to exces-
sive pulling, bending and crushing forces. Consult the cable
specification sheet for the cable you are installing. Do not bend
cable more sharply than the minimum recommended bend
radius. Do not apply more pulling force to the cable than spec-
ified. Do not crush the cable or allow it to kink. Doing so may
cause damage that can alter the transmission characteristics of
the cable- the cable may have to be replaced.

4.2 Measure the cable outside diameter and determine
the proper grip to use based on the supplier’s recommen-
dations
4.3 Once the proper grip is obtained, inspect it for dam-
age, broken wires, bulges due to stress, rust, etc.
Grasp the pulling eye in one hand (gloves recommended)
and smooth out the mesh with the other, tightening the
wires.
Figure 2 illustrates the technique, which is critical when
reusing grips.
Figure 2
4.4 Trim the end of the cable with side cutters
(Figure 3) to remove any protruding tube, strength
member, or armor.
Figure 3
4.5 se a pumping action to “walk” the grip over the
jacket by bringing your hands together and then relaxing
them (Figure 4).
Figure 4
4.6 Position the cable in the grip so that the end of the
cable is 0.25 inches (6 mm) behind the grip’s basket
(Figure 5).
Figure 5
4.7 Compress the basket so that it is no larger than the
combined OD of the grip and cable (Figure 6).
Figure 6
4.8 Smooth the mesh back over the cable, moving from
the pulling eye to the cable jacket.
4.9 Tug on the grip to tighten its grip on the cable.
4.10 Start at least 1.0 inch (2.5 cm) below the mesh on
the cable and wrap vinyl tape TIGHTLY to the top of the
grip.
The mesh’s imprint should show boldly through the tape
(Figure 7). The tape must be tight because it helps com-
press the mesh against the cable. Lightly tug on the grip
to press it against the cable.

4.11 Figure 8 illustrates a completed grip.

4.12 Connect the pulling eye to the appropriate ball
bearing swivel and pulling tape or rope (Figure 9). The
grip installation is now ready for the cable pull.

5. Grip Removal
5.1 To remove the pulling grip after completion of the
pull:
a) Cut the cable 3 ft (91 cm) behind the grip.
b) Place a protective cap over the exposed cable end
and tape in place to prevent water intrusion.
c) Store the coiled splicing slack so that it is protected
from damage.
