Product Description
ND70PD-SPA-605 Schlage ND Series Cylindrical Lever Lock — Classroom Lock, Sparta Lever, Bright Brass
A room where one person controls the door with a key, and nobody inside can change it. That is the ND70. There is no button. The key in the outside lever locks or unlocks the outside lever, and the inside lever always lets people out. The trade-off is plain: to lock this door, somebody has to be standing in the hall with a key.
This one is the Sparta lever on the Rhodes rose, with a conventional 6-pin cylinder keyed 5, in the Schlage C keyway, keyed different, in Bright Brass. The latch is a deadlatch. Want the outside lever to spin free when locked? Schlage sells that as Vandlgard, function ND94. Pick your backset in the dropdown: 2-3/4" is standard, 2-3/8" is the other choice. Measure from the door edge to the center of the bore before you order.

Pro-Installer FAQ
Q: Can I lock this from inside the room?
A: No. The only place to lock it is the key in the outside lever. If the door has to lock from inside, Schlage's ND78 is the classroom security lock, with a key in both levers.
Q: Will this key into my building's system?
A: Only if your building runs the Schlage C keyway. It ships keyed different, not master keyed. Schlage's default on most ND orders is Everest 29 S123, and that is a different key, so check which one you have before you order.
Q: Is this a Grade 1 lock?
A: Yes. The ND Series is ANSI/BHMA Certified A156.2 Grade 1, Series 4000. If the job does not call for Grade 1, Schlage's ALX Series is the Grade 2 cylindrical line.
