Add the NSFs of the flush-mounted devices to get the total NSF.
–
Use the total NSF to get the length (x) of the recess from the table. The length includes
the DCN-FCOUP couple pieces.
Notice!
Install DCN-FEC End Caps on the couple pieces at the two ends of the recess.

Number-size factor
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 the table)
of the flush-mounted devices.
