3M™ Closure System 2-Type 505 Ordering Information
To select the correct cover:
1. Determine number of cable pairs
2. Determine splice bundle diameter
3. Determine sheath opening required
To select the correct endplate:
4. Determine cable entrance configuration
5. Determine outside diameter of each cable
(Outside cable diameter must not exceed pre-sized opening in endplate)
Example:
Number of cable pairs = 1200/24 gauge
Splice bundle diameter = 6" (152 mm)
Sheath opening = 19" (483 mm)
Cable configuration = 3-way
1200 pairs in/600 pairs out x 600 pairs out
Cable outside diameters:
1200 pairs = 2.6" (66 mm)
600 pairs = 1.9" (48 mm)

2B2-2E Endplate Assembly
A complete 2-Type Closure for enclosing
spliced connections of communication
cables requires the selection of one (1) cover
assembly kit and two (2) endplate assembly
kits from the same series. Note from the
example that the cover series (2B2) matches
the endplate series (2B2). This ordering
procedure is an approximate guide only.
Proper cover and endplate selection will vary
with type of splice connectors and splicing
method used.
