9.0 Cable Port Sealing
The two methods to seal the cable ports of the cabinets use plastic split glands or steel ports. Follow your
company's procedure for which type to use. The gland and port dimensions are the maximum cable diameter
that fit the sealing methods. Unused openings are to have sealed cover plates.
9.1
Plastic Split Gland Kits
The opening of the 3M™ Flanged Gland Kit 4097-F
is 2 5/8" and the 3M Flanged Gland Kit 4097-BF is
3 3/8". Follow the instructions included with each
kit for the sealing of a cable in the cabinet.
9.2
Steel Cable Port Kits
There are three sizes of the steel ports: 2 5/8", 3
3/8" and 4". The kits include a steel port, sealing
tape and a collapsible rubber tube called the 3M™
Pull N' Shrink Tube (PST).
a. Scuff and round out the area of sheath where the
sealing tape and port will be located.
Sealing cable with 3M™ Split Gland Kit 4097-F & BE
b. Slide the PST, (pull cord must be opposite the
cabinet) the steel port and gasket over the cable.
c. Wrap sealing tape approximately 1" away from
cabinet so it will center the cable in the steel
port. Position and install the gasket and steel port
to the cabinet as shown in the drawing.
d. Build an even transition from the steel port to the
cable with more sealing tape.
e. Install the PST over the tape and steel port. Unwind
the pull cord of the PST counterclockwise until the
tube is collapsed and the core is removed.

10.2 3M™ Pole Mount Cabinets 4295 E and F
Note: Because of the large cable pair counts of
these cabinets, the amounts of extra cable slack and
the location of tie points have to be judged by good
housekeeping rules.
a. Secure the frame in the open position.
b. Separate and match the cable(s) groups into
100 pair bundles with the blocks in the hinge
column first.
c. Tie groups to the left on the cabinet tie bars.
Any cable slack (your company practice) can be
stored here.
Figure 1
d. Allow for a 6" to 9" swing loop and tie the
groups to the frame's hinge column of matching
blocks. Move the tie points down the frame and
tie bars as needed to complete this column. Make
sure slack loops will not be pinched when frame
is closed. (Figure 1)
e. Splice the cable and stubs according to your
company practice. Tie modular connectors to the
rear of the block frame. Close frame assembly,
check for possible wire pinching.
f. Tie the cable for the middle and outer column,
from the Cabinet Tie Bar to the frames without a
loop (Figure 2). Start at the top of the frame and
work down. Make sure these tie points will not
be pinched or obstruct the closing of the frame.
Figure 2
g. Splice the cable and stubs according to your
company practice, one column at a time.
h. Tie modular connectors to the rear of the block
frame. Close frame assembly, check for possible
wire pinching.

Boxes 4075-S and 4077 Series.
Note: When using 3M™ MS2™ Modules, 4075-S, 4077
Sealant Boxes or 3M™ 710 Connectors containing
sealants, carefully follow safety, health and
environmental information on appropriate Material
Safety Data Sheet.
