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).
2. TOOLS AND EQUIPMENT REQUIRED

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.

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.

3.11 Attach Frame to End Cap
Step 1 Secure the end cap on the work
surface (table). An optional
installation bracket (purchased
separately) is available.
Step 2 Separate the ribbon fibers from
the drop port into two groups.
Step 3 Lay all the ribbon fiber from
the express ports in a bundle
between the two groups
(Figure 28).
Step 4 Hold the uncut express fibers in
one hand and the ORS frame in
the other hand.
Step 5 Carefully reposition the ORS
frame and secure it to the end
cap.

WARNING: Never look
directly into the end of a fiber
that may be carrying laser light.
Laser light may be invisible and
can damage your eyes. Viewing it
directly does not cause pain. The
iris of the eye will not close
involuntarily as when viewing a
bright light. Consequently,

serious damage to the retina of the eye is possible. Should accidental eye exposure to laser
light be suspected, arrange for an eye examination immediately.
WARNING: DO NOT use magnifiers in the presence of laser radiation. Diffused
laser light can cause eye damage if focused with optical instruments. Should accidental eye
exposure be suspected, arrange for an eye examination immediately.
IMPORTANT: Basic ribbon fiber routing requires Ribbon “A” spliced to Ribbon “B”. Ribbon “B”
will be routed to the side storage compartment and side of the splice plane opposite
from ribbon “A”.
3.12.1 Route express fibers
Step 1 Loop the express ribbon in the middle compartment of the ORS and temporarily
secure with tape.
IMPORTANT: DO NOT secure the uncut express slack in the plastic clip (“A”) on the interior of
the middle compartment. This clip is to secure the fibers from the express port that
are to be spliced as they are routed from the express compartment to the side storage
compartment.

Step 2 Determine the length
required and cut the express
fibers to be spliced.
Step 3 Open the first clip (“A”) in
the middle compartment.
Step 4 Route the cut express fibers
(that are to be spliced)
through the clip and into the
side storage area. Note the
counterclockwise path as
shown in Figures 29 and 30
for this particular side.
Step 5 Loop all the express ribbon
fibers (that are to be spliced)
from the express area and into
their respective side storage
areas.
NOTE: A loop of fiber slack can be stored in
the side storage areas with the loop
routed respectively for each side as
shown in Figure 29. The loop is
limited at the bottom by the metal
retaining bracket and at the top by
the plastic clip (“B”).

IMPORTANT: Before cutting, make sure there is a complete loop of fibers in the side storage
compartment and the fibers lie neatly in the trough of the splice plane.
3.13.1 Prepare fibers for splicing
Step 1 To ensure the appropriate length of slack fibers, cut the fibers extending beyond
the bottom of the closure as shown in Figure 35.
Step 2 Remove the tape from the fibers.
Step 3 Remove the fibers from the top plastic clips (Clip “C”).
Step 4 Lay all fibers on the table.
Tape to Endcap
Step 5 Determine which two ribbon
fibers are to be spliced (one
from the left and one from the
right).
Step 6 Route them through the clip
again and into the bottom of
the closure. Do not close the
clip at this time.
Step 7 Bring the two fibers to the first
position in the organizer.
Step 8 Temporarily lay the fibers in
the organizer to determine the
required length.

Step 9 Cut both fibers at the same time in the center of the organizer.
3.13.2 Splice fibers
Splice the fibers according to the instructions for the splicing equipment you are using:
Step 1 Insert the protected splice (heatshrink splice protectors are recommended) back
into the first slot in the organizer.
Step 2 Repeat from Step 5 in Section 3.13.1 for all required splices. Install splices into the
organizer consecutively (Figure 36).
SCF-6 SCF-8
NOTE: Each slot in the organizer accepts
two splices. Install the second
splice on top of the first splice
before proceeding to the next slot
in the organizer.
Step 3 Secure the spliced ribbons
in the clips (Clip “C”) on
the splicing plane
(Figure 34). Confirm the
fibers do not exceed the
minimum bend radius.

3.14 Splicing in Trays (Optional)
Splice trays (purchased separately) can be used when the drop cable is single-fiber cable with
buffer tubes or small central tubes. A ribbon strain-relief kit (p/n SCF-KT-RTK, purchased
separately) is required before the ribbon can be safely secured to a splice tray. Follow the
instructions provided with the kit.
Figure 39 — Mark Buffer Tube
3.14.1 Select the buffer tube to be spliced
Step 1 Remove the plastic cover from the
side compartment.
Step 2 Route the buffer tube on the
outside of the tray to make sure
there is a loop of fiber (Figure 39).
Step 3 Attach the buffer tube loosely to
the tray using a cable tie
(Figure 39).
Step 4 Mark the buffer tube with a
permanent marker 19 mm
(0.75 inches) from the cable tie.
Step 5 Remove the buffer tube beyond this mark in segments of approximately 304 mm
(12 inches).
Step 6 Prepare all splice trays in the same manner.
Step 7 Follow the instructions provided with the splice tray for detailed splicing
instructions.
IMPORTANT: Do not store buffer tube slack in the same area as the ribbon fibers. Damage to the
ribbon fibers can occur.
