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 to the
table) of the flush-mounted devices.
