About the ND Series

The Schlage ND Series is the heavy-duty cylindrical lever lock that many architects specify for schools, hospitals, offices and other busy commercial buildings. It is certified to ANSI/BHMA A156.2 Grade 1, the highest cylindrical lock grade, and is UL listed for use on fire-rated doors. Levers are field reversible, so one lock fits left- or right-hand doors, and the lever shapes meet ADA requirements for operation without tight grasping or twisting.

Because the ND fits a standard 161 cylindrical door prep (2-1/8" bore, 2-3/4" backset), it is a common upgrade when replacing worn or lighter-duty locks without re-machining the door.

Specifications

Questions and answers

Does it come with a cylinder or core?
Includes a conventional Schlage cylinder in the S123 keyway.

Will it fit my existing door?
It fits a standard cylindrical prep: 2-1/8" bore with a 2-3/4" backset on doors 1-5/8" to 2-1/8" thick. Other backsets and thin-door kits are available; ask us if your door is different.

Is it fire rated?
The ND Series is UL listed for fire-rated doors when installed with a compatible latch and strike.

Which hand door does it fit?
Either. ND levers are field reversible, so the same lock works on left- and right-hand doors.
