5. 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.
5.1 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 illustration, if necessary.
Do not expose the bare fibers until after the cable has been placed in the closure end
cap.
Step 1 For express (midspan) cable applications remove 3 meters (118 inches) of the
cable sheath (and armor, if included) as indicated in Figure 2.

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, if present) 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 end cap in
a later step.

5.3 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.
• Strength members in cables (central tube) with sheath-mounted GRP (Glass Reinforced
Plastic) 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 5.2.
5.3.1 Strain-relief bracket(s)
Install strain-relief bracket(s) onto the opposite side (180 degrees) from the grounding clamp
when applicable:
Step 1 Place a hose clamp over the cable and bracket approximately 18 mm (0.75 inches)
below the sheath end (Figure 5).
IMPORTANT: If grounding hardware is used, make sure the hose clamp does not overlap the ground
clamp.

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.
5.3.4 Large strength members
For cables with large strength members,
use the large central member strian-relief
kit (p/n SCF-MBR-CMS, purchased
separately) instead of the restraint caps
(Figure 9):
Step 1 Slide the metal barrel over
the end of the central
member.
Step 2 Align the threads in the side
of the barrel with the hole in
the top of the strain-relief
bracket.
Step 3 Install the supplied screw
through the threaded hole in
the barrel.
Step 4 Tighten the screw.
Step 5 Trim the strength member
flush with the top of the
strain-relief bracket.

CAUTION: Use sealing paste and cable
cleaner in a well-ventilated area to eliminate the
possibility of dizziness and nausea. If paste or
cleaner comes in contact with skin or eyes, wash
area immediately with soap and water to avoid
irritation. Do not induce vomiting if paste
cleaner is ingested.
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 13,
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. Allow the sealing paste to
dry.

Figure 14 — Sealing Tape
Step 3 Cut and pull the strip of
sealing tape as shown in
Figure 14. The tape will
stretch and thin before it
breaks.
Step 4 Starting at the mark
shown in Figure 13, wrap
the tape around the cable
until it fills the diameter
“C” on the end cap
gauge tool (Figure 15A).
Express ports will
accommodate cable with
a maximum diameter of
25 mm (1.0 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 approximately
0.5 inch (Figure 15B).

Step 5 Repeat Section 5.4.1 and 5.4.2 for the other cable to be installed in the express
port, if applicable.
5.4.3 Use a dummy plug
When the closure only has one cable installed in either
end cap, use a dummy plug (p/n SCF-4-6-PLUG,
purchased separately) to fill the unused port.
Step 1 If using a dummy plug follow instructions
in Section 5.4.2 to install sealing paste and
tape to dummy plug.
Step 2 Install dummy plug with the closed end of
the plug flush against the outside of the
end cap (Figure 16).
5.4.4 Install cable
Step 1 Wrap hose clamps and restraint caps with vinyl tape to prevent the sharp edges
from damaging the fiber.
Step 2 Place one side of the express cable sheath in the express port on the untaped end
cap half by inserting the strain-relief bracket in the tracks.
Step 3 Place the other side of the express cable sheath on the taped end cap half
(Figure 17) in the center express port by inserting the strain-relief bracket in the
tracks.

relief bracket remain
inside the tracks. Do not
use power tools to tighten.
Step 5 Tighten the bolts until the end cap closing gauge tool (Section H) fits over the
sides and center measuring points of the end cap (Figure 19).
Step 6 Cut excess sealing tape from the sealing ring channel and strain-relief tracks
(shown by dashed circles in Figure 17) using scissors or side cutters.
NOTE: Do not pull or stretch sealing tape.
Step 7 Completely remove any remaining sealing tape inside the sealing ring channel with
the blade of a screwdriver.
