3.03 If the cable is a ribbon, unitue or slotted core, loose tubes
from a unit splitter kit will be placed over the fibers to be
spliced for protection.
3.04 Secure the cables to the closure per the closure practice.

in a
COUNTERCLOCKWISE
direction. Buffer tubes
should exit the closure in the corner where they will enter
the splice trays.
3.06 Trim the buffer tubes (without cutting the fibers) to the
middle of the closure. Leave at least 75% of one coil
buffer tubing intact.
3.07 Clean the grease from the fiber per company practice.
3.08 Cut the supplied tubing into 12" (305 mm) pieces.
3.09 Slide a segment of tubing over the fibers until it contacts
the buffer tube end. No more than twelve 250 µm fibers or
four 900 µm fibers should be placed into a tube.
3.10 Slide the segment of tubing over the buffer tube about 1"
(25 mm) and secure with two wraps of vinyl tape.
