2181-LS Cable Addition Kit Adapter Installation
11.1
Installation procedures for the 2181-LS Adapters are the same as the 3M
™
2178-L/S Series Splice Cases
(Sections 4.0 - 9.0) with the following exceptions:
For SINGLE Adapter Installation, replace all ten bolts inserted in the closure cover with the ten bolts
supplied with the 2181-LS Cable Addition Kit.
For DOUBLE Adapter Installation, replace all ten bolts inserted in the closure cover with the ten longer
bolts supplied with the 3M
™
2181-B Cable Addition Kit.
For TRIPLE Adapter Installation, replace all ten bolts inserted in the closure cover with the ten longer
bolts supplied with the 3M
™
2181-C Cable Addition Kit.
Note:
The 2181-B and the 2181-C Cable Addition Kits contain only the longer bolts. The 2181-LS Cable
Addition Kit is needed to add an adapter.
11.2
The tray support can be installed in the closure base or any of the adapters. Install the tray support onto
the desired level by placing it into the slots on the closure base or adapter, and tightening the screws until
snug.
11.3
If needed, two tray supports can be used. Tray supports may be ordered separately as the 3M
™
2178-STS
(for the 3M
™
2178-S Splice Case), and 3M
™
2178-LTS (for the 3M
™
2178-LS Splice Case and the 3M
™
2178-LL Splice Case). Install the lower level tray support first. Install organizers and splices per
company standard or organizer installation instructions. Then install the next level tray support with the
next level of organizers and splices.
11.4
The following steps are for all adapters installed:
a.
To prevent cables from being damaged or pinched
between adapters and the closure, the adapters can be
pulled down into place before the closure cover is
installed. If using more than one adapter, remove all
corner inserts on the lower level adapter(s). A
screwdriver can be used to take out the corner
inserts.
b. The threaded inserts should be in the four corners on
the top portion of the top adapter only. The raised
threads should be facing down so that the insert
surface is flush with the adapter.
c.
Prior to placing an adapter on the closure base,
ensure that the note "AIR VALVE END" on the
adapter is aligned with the "AIR VALVE END" note
on the gaskets and the closure base.
