2.0 Drop Cable Preparation

2.1 Determine how many drop cables will be

passing through the 3M™ Multiport Grommet.

2.2 Remove sheath on drops exposing buffer tubes

to a length required per company practice.

Note: An additional method to ease installation is to

take sheath scuff supplied in closure kits, and

slightly sand the leading edge of the drop cable

and blank plugs.

2.3 Trim the strength members back to 1.75"

(44.4 mm) in length.

2.4 Place a small amount of lubricant (provided in

kit) on blank plugs and cable to allow for ease

of installation into multiport grommet.

Note: Follow health, safety and environmental

information on product label or Material Safety

Data Sheet (MSDS) for Silicone Lubricant.

2.5 Grease approximately 2" of cable drop jacket.

2.6 Insert drops into multiport grommet first and

then insert blank plugs last.

2.7 Insert drop 1"–2" into multiport grommet and

then pull back out.

2.8 Insert drop the entire length of multiport

grommet.

2.9 Repeat steps 2.4–2.8 for the blank plugs as well.

Note: Leave future ports orientated to top of closure

for ease of future installations of drop.

Note: Ensure that the extruded retention feature of

strain relief has sufficient contact with surface

of grommet.
