1. General
This document describes the installation of the
WCH-SSH Slack Storage Housing manufactured by
Corning Cable Systems.
2. Description
2.1 The WCH-SSH is a wall mountable slack
storage unit designed to hold splice trays and cable
slack. The unit will support a WCH housing and has
1 3-inch knockout(s) in its cover for hidden cable
routing directly to the WCH.
2.2 Two Slack Storage Housings are available:
The WCH-SSH-2 designed to hold a WCH-02P and
a WCH-SSH-4-12 designed to hold a WCH 04P,
06P, 08P, and 12P.
2.3 Splice trays are secured inside the housing
with a Velcro® strap. The WCH-SSH-4-12
accomodates up to eight 0.2-inch or four 0.4-inch
splice trays including M67, M68, and UST-024. The
WCH-SSH-2 accomodates four 0.2-inch or two 0.4-
inch splice trays (M67-042, 060, 061, and 068).

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.
NOTICE: 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 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: Never look directly into the end
of a fiber that may be carrying laser light. Laser
light may be invisible. Laser light 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 to laser light be suspected,
arrange for an eye examination immediately.
WARNING: Cleaved glass fibers are very sharp
and can pierce the skin easily. Do not let cut pieces of
fiber stick to your clothing or drop in the work area
where they can cause injury later. Use tweezers to pick
up cut or broken pieces of the glass fibers and place them
on a loop of tape kept for that purpose alone. Good
housekeeping is very important.
3. Tools and Materials
Tools and materials needed to install the WCH-SSH
include
• Phillips screwdriver
• Slotted screwdriver
• 216B tool
• Needle-Nose Pliers
• Black Felt-Tip Pen
• Strain-Relief Kit (supplied)
4. Precautions
Read and understand precautions for the cable and
splicing method you are using (Figure 2).

5. SSH Mounting (to the wall)
5.1 Open the front door of the unit. Place the
housing on the wall mounting surface. Mark the four
mounting holes with a black felt-tip pen. Mounting
surface should be flat to prevent warping.
5.2 Drive anchors or wood screws in at these
locations leaving a 1/8-inch gap between the
mounting surface and screw or bolt-head.
NOTE: Mounting hardware not provided.
5.3 Place the unit on the mounting hardware and
tighten the hardware.

6.1 Remove the appropriate knockouts in the SSH
door and the WCH backplate (Figure 4).
6.2 Start screws in the appropriate holes in the
door of the SSH (Figure 4). Four screws are provided
in the kit.
6.3 Place the WCH on the screws and tighten the
screws.

7. Cable Strain Relief
7.1 If the cable you are installing has aramid or
fiber-glass yarn and a central member, strain-relieve
it using the strain-relief bracket and hardware
provided.
Figure 6
7.2 Remove cable sheath as specified in
instructions for the cable you are installing.
Suggested lengths are illustrated in Figure 6.
7.3 Insert the square neck bolt from one side of the
strain-relief bracket. Wrap the aramid yarn around
the bolt on the opposite side of the strain-relief
bracket from which the bolt was inserted. Place U-
shaped washer over the square neck bolt. Insert the
central member in the U-shaped washer and place the
2 flat washers on top and secure with the wing nut
provided.
7.4 Use cable ties for additional strain relief
(Figure 5).
NOTE: Avoid overtightening the cable ties.
Overtightening may cause macro/micro bending and
damage the cable.
Both the aramid or fiberglass yarn and
the central member are secured with a
U-shaped washer and a bolt. Wrap yarn
between the U-shaped washer and the
side of the bracket. Insert the metallic
central member between the U-shaped
washer and the flat washer. Tighten
the nut.
Yarn: 15 cm (6 inches)

8. Splicing
8.1 If you are installing splice trays, complete
splicing and tray routing per instructions for the tray
and splicing method you are using.
8.2 Secure the trays with a Velcro strap (Figure 7).
9. Cable Routing
9.1 When installing the WCH to a SSH, leave
some unsecured cable slack in the slack storage
housing to allow access into the SSH cabinet without
damaging the fibers or buffer tubes when opening the
cabinet. Route cables inside the housing as illustrated
in Figure 7.
9.2 When closing the unit, make sure none of the
fibers will be pinched when the front panel is
replaced.
