19.3.2 Block-mounting
Refer to figure 19.2 for the dimensions of a recess for
the block-mounting method.
figure 19.3: Recess, block-mounting method
The length (x) of a recess depends on the total
number-size factor (NSF) of the flush-mounted devices
that must be installed in the recess. To calculate the
length of a recess:
1 For each flush-mounted device, get the number-size
factor (NSF) from table 19.3.
2 Add the NSFs of the flush-mounted devices to get
the total NSF.
3 Use the total NSF to get the length (x) of the recess
from table 19.2. The length includes the
DCN-FCOUP couple pieces.
Note
Install DCN-FEC End Caps on the couple
pieces at the two ends of the recess.

The length of a recess depends on:
•
The number of flush-mounted devices that are
installed in the recess.
•
The size of the flush-mounted devices that are
installed in the recess.
To calculate the length of a recess, you must use the
number-size factor (NSF, refer to table 19.3) of the
flush-mounted devices.
