1GENERAL
The Three Tier Clamp kit (OSP-CLPFEC-LG) is designed for use in the Fiber Entrance
Cabinet (FEC). The FEC uses a water resistant grommet with three cutouts to
accommodate multiple and various sized cables in each entry port. The OSP-
CLPFEC-LG kit covers cable with outside diameters from 0.80 inch to 1.2 inches (20
mm to 30 mm). Table 1 lists the kit components.

The OSP-CLPFEC LG kit uses special male/female bolts and spacer plates to provide
for three tier stacking. Male/female bolts thread into each other to accomplish the
stacking. The spacer plates have two cutout slots the size of the bolt head. The
slots keep the bolts from turning as the next bolt is threaded into it.

2 INSTALLATION
The cable clamps are installed after the cable ground clamp and moisture blocking
has been completed. The cable entry port grommet is removed for the ground
clamp and moisture blocking procedures. After those operations are complete,
install the cable clamps as described below.
2.1 One Cable Per Entry Port With Possible Future Cable Addition
(Figure 2A)
Use this procedure to install the first cable.
1. Cut out an appropriate size opening in the grommet that is the closest in size
to the outside diameter for the cable being installed.
2. Insert the grommet into the cable entryslot. Start with the top groove first
and press the grommet into the slot.
3. Attach a set of clamp yokes to the cable termination and grounding plate with
male/female bolts. Thread in the top bolt only at this time. Do not tighten.
4. Route the cable through the hole cut in the grommet and into the cable clamp.
Use split grommets as required to assure a tight fit. Thread in the lower bolt
and tighten both bolts.
5. Connect the ground straps to the cable terminating and grounding plate as
shown in Figure 3.

2.2 Two Cables Per Entry Port (Figure 2B)
Use this procedure to install a second cable.
1. Cut out the appropriate size openings in the grommet that is the closest in size
to the outside diameter for the cable being installed.
2. Attach the second set of clamp yokes to the clamp already in position.
a. Place the spacer bracket over the bolt heads of the first clamp. Ensure the
bolt heads are aligned to allow the bracket to slide over the bolt heads.
b. Thread a male/female bolt through the top holes of the second set of clamp
yokes into the top male/female bolt of the first clamp. Do not tighten at
this time.
3. Route the cable through the hole cut in the grommet and into the cable clamp.
Use split grommets as required to assure a tight fit. Thread the lower bolt
through the bottom holes of the clamp yokes. Check that the spacer bracket is
in place and tighten both bolts.
Note: Do not remove the spacer bracket after the bolts are tightened.
4. Connect the ground straps to the cable terminating and grounding plate as
shown in Figure 3.
2.3 Three Cables Per Entry Port (Figure 2C)
Use this procedure to install a third cable.
1. Cut out the appropriate size openings in the grommet that is the closest in size
to the outside diameter for the cable being installed.
2. Attach the third set of clamp yokes to the clamp already in position.
a. Place the spacer bracket over the bolt heads of the second clamp. Ensure
the bolt heads are aligned to allow the bracket to slide over the bolt heads.
b. Thread a male/female bolt through the top holes of the third set of clamp
yokes into the top male/female bolt of the second clamp. Do not tighten at
this time.
3. Route the cable through the hole cut in the grommet and into the cable clamp.
Use split grommets as required to assure a tight fit. Thread the lower bolt
through the bottom holes of the clamp yokes. Check that the spacer bracket is
in place and tighten both bolts.
Note: Do not remove the spacer bracket after the bolts are tightened.
4. Connect the ground straps to the cable terminating and grounding plate as
shown in Figure 3.
