3. INSTALLING THE CLOSURE
NOTE: Fiber optic cable is sensitive to excessive pulling, bending and crushing forces. Consult the cable
specification sheet for the cable you are installing. Do not bend the cable more sharply than the
minimum recommended bend radius. Do not apply more pulling force to the cable than
specified. 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.
WARNING: Do not install this unit or work with telephone wiring during a
lightning storm. Telephone lines can carry high voltages from lightning causing electrical
shock resulting in severe injury or death.
CAUTION: The wearing of safety glasses to protect the eyes from accidental injury is
strongly recommended when handling chemicals and cutting fiber. Pieces of glass fiber are
very sharp and can damage the cornea easily.
CAUTION: The wearing of safety gloves to protect hands from accidental injury is
strongly recommended when using sharp instruments.
3.1 Prepare the Express Cable
IMPORTANT: Typical lengths are illustrated. Since the actual application may vary, it is
recommended to route the buffer tubes as they will lie in the closure to determine
actual strip lengths before cutting fibers. Refer to routing illustrations, if necessary.
Step 1 Remove indicated length of cable sheath and armor (where applicable) according
to cable manufacturer’s instructions (Figure 2).
NOTE: Do not expose the bare fibers until after the cable has been placed in the closure end cap.
Step 2 Cut the central strength member of each cable to 15 cm (6 inches) from the sheath
using side cutters.
Step 3 If aramid yarn is present, leave an excess length of yarn (approximately 6 inches)
for additional strain-relieving.
IMPORTANT: To prevent damage to the fiber, remove all uncut express fiber from the tubing using
the universal access tool (p/n UAT2-000 - purchased separately).

Step 1 Cut a slit into opposite sides of the
outer sheath and armor about 2.5
cm (1 inch). To do this, score the
armor with a cable knife (being
careful not to damage the inner
sheath) and split the sheath by
flexing it.
Step 2 Position the grounding clamp base
plate under the armor. The stops of
the clamp should just touch the
outside of the armor and sheath.
Tap the sheath above the ground
clamp base to drive the teeth on the
plate into the cable sheath.
Step 3 Position the top plate and lock nut
on the outer sheath over the base
plate. Tighten with a 3/8-inch
wrench so that the teeth on the
upper plate are driven into the
sheath.
NOTE: When the cable has metal strength
members, attach the extension bracket to
the base plate as shown in the inset before
installing the top plate.
Step 4 Wrap the grounding clamp and
split portion of the cable sheath
with vinyl tape.
Step 5 Place the eyelet on the ground wire
over the stud on the base plate. Add
a second lock nut and tighten using
a 3/8-inch wrench.
NOTE: Ground lead will be attached to endcap in a
later step.

3.3 Install Express Strain-relief Hardware
Determine cable and strength member type and proceed accordingly:
• Strength members in single-tube cables must be separated by the restraint cap threaded
stud.
• Single strength members in loose tube design cables must be secured in the cap.
• Cables (central tube) with sheath-mounted GRP (Glass Reinforced Plastic) strength
members need only the strength member(s) on one side of the cable secured in the cap.
IMPORTANT: If the cable used is made with metallic strength members, use the grounding
hardware as for the armored cable, with the extension bracket to strain-relieve the
metallic strength members and ground them. Refer to Section 3.2.
3.3.1 Strain-relief bracket(s)
Install strain-relief bracket(s) onto the opposite side (180 degrees) from the grounding clamp, if
applicable:
Step 1 Place a hose clamp over the cable and bracket 18 mm (0.75 inches) below the
sheath end.
IMPORTANT: If grounding hardware is used, make sure the hose clamp does not overlap the ground
clamp.

to a torque value of 10 in-lb for
nonarmored cable or 17 in-lb for
armored cable.
Step 3 Place a washer over the threaded
stud on the strain-relief bracket.
Step 4 Wrap the yarn (if present) twice,
clockwise, around the threaded
stud (Figure 4).
Step 5 Install a washer and nut and
tighten securely.
Step 6 Mark the cable in the location
shown in Figure 4.
Step 7 Repeat for the second cable,
when applicable.

3.3.2 Nonmetallic strength member
If strength member is nonmetallic:
Step 1 Trim the strength member flush with the top of the strain-relief bracket (Figure 5).
Step 2 Insert the restraint cap threaded stud
through the upper hole in the strain-
relief bracket capturing the strength
member between the two.
Step 3 With the nonmetallic strength
member behind the bracket, install a
nut on the restraint cap threaded stud
(Figure 5).
Step 4 Confirm buffer tubes are clear of the
strength elements. Tighten nut
securely.
Step 5 Repeat for the second cable, when
applicable.
3.3.3 Metallic strength members
If strength members are metallic:
Step 1 Bend them over the slots in the extension bracket as shown in the inset in Figure 6
and then trim excess strength member.
Step 2 Insert the restraint cap threaded stud through the upper hole in the strain-relief
bracket capturing the strength member between the two.
Step 3 Install restraint cap as shown in Figure 6.
Step 4 Install a washer and nut and tighten securely.
Step 5 Repeat for other cables, when applicable.
IMPORTANT: Confirm all buffer tubes are clear of the strength elements prior to securing the
restraint cap.

Step 1 Slide the metal tube over the end
of the central member.
Step 2 Align the threads in the side of the
tube with the hole in the top of the
strain-relief bracket.
Step 3 Install the supplied screw through
the threaded hole in the tube.
Step 4 Tighten the screw.
Step 5 Trim the strength member flush
with the top of the strain-relief
bracket.

3.4 Install Cable into the Endcap Express Ports
NOTE: Installation is illustrated using the SCF-8 closure;
the procedure is the same for the SCF-6 closure.
3.4.1 Prepare the endcap
Step 1 Remove the frame from the end cap.
Step 2 Pull the end cap halves apart.
IMPORTANT: Do not use power tools to separate the
end caps.
NOTE: Use the two main cable ports in the center of the
end cap first (Figure 8). Use the drop ports as
needed.
Step 3 Beginning with the inside of the end
cap, apply sealing tape to the end cap
half containing the metallic standoffs
(Figure 9). Cut holes in the tape to
expose the standoffs.
IMPORTANT: It is imperative that the strain-relief
bracket have no contact with the tape.
Make sure the strain-relief tracks on
the inside of the end cap and the screw
holes are not obstructed by the sealing
tape.

Step 4 Starting at the mark shown in
Figure 10, wrap the tape
around the cable until it fills
the diameter “C” on the
combination wrench tool
(Figure 12a). Express ports
will accommodate cable with
a maximum diameter of 32
mm (1.2 inch); some cables
require only one wrap of
sealing tape to reach this
diameter. Always finish with a
complete wrap that overlaps
the starting point by 1/2inch
(Figure 12b).
3.4.2 Apply sealing tape to the cable
CAUTION: Isopropyl alcohol is flammable with a flashpoint at 54
° F. It can cause
irritation to eyes on contact. In case of eye contact, flush eyes with water for at least 15
minutes. Inhaling fumes may induce mild dizziness. In case of ingestion, consult a
physician.
Figure 10 — Apply Sealing Paste
Figure 11 — Sealing Tape
AB
Figure 12 — Measure Sealing Tape Around Cable
Step 1 Clean the cable where the tape will be
applied using the provided alcohol pad.
Step 2 Beginning at the mark shown in Figure 10,
use wax-paper backing from the sealing tape
to spread the “dichtpaste” sealing paste
evenly around the cable in the area where
the sealing tape will be applied (Figure 10).
Wait for the sealing paste to dry.
Step 3 Cut and pull the strip of sealing
tape as shown in Figure 11. The
tape will stretch and thin before it
breaks.
NOTE: The combination wrench is used in several steps during the assembly process. Use only this
wrench for measuring and tightening components where indicated (Table 1).
Step 5 Repeat Section 3.4.1 and 3.4.2 for the other cable to be installed in the express
port, if applicable.
