Product Description
ND53JD-SPA-612 Schlage ND Series Cylindrical Lever Lock — Entrance Lock, Sparta Lever, Satin Bronze
A front desk door needs two kinds of locked. Locked until the next person opens it, and locked until somebody means to unlock it. The ND53 has a push/turn button in the inside lever for that. Push the button and a key or a turn of the inside lever unlocks the door, same as an office lock. Push and turn it and they only pull the latch back; the outside lever stays locked until the button is turned back to its start position. The key outside never locks this lock.
This one is the Sparta lever on the Rhodes rose, with its lever prepped for a full size interchangeable core and no core in the box, in Satin Bronze. The latch is a deadlatch. Want the outside lever to spin free when locked? Schlage sells that as Vandlgard, function ND92. 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: What is the catch with the push/turn button?
A: Lock-out. If you walk out with the button pushed and turned and do not fully release it, the outside lever stays locked behind you. Schlage prints that caution on this function, so tell whoever uses the door.
Q: Which core goes in this?
A: A full size interchangeable core, bought separately. This one is less core, so the lever arrives ready for it with nothing in it.
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.
