Schlage ND25X70L LLL XXX LLL LLL – Frequently Asked Questions

1) What exactly comes in the Schlage ND25X70L, and what do I still need to order?
The ND25X70L is the bare lock chassis only, supplied less all possible parts and unfinished. There is no lever trim, no rose or escutcheon, no cylinder, no latch and no strike with it. You are buying the mechanical core of an ND Series classroom exit lock and pairing it with the ND trim, latch and cylinder you already have or order separately. Plan the job that way before you schedule the door.
2) What does the classroom exit function on the Schlage ND25 chassis actually do at the door?
Classroom exit means the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. Nobody gets trapped in the room regardless of how the outside is set. That is why it turns up in school corridors, healthcare and government buildings where egress has to stay clear at all times.
3) Will this chassis work with my existing Schlage ND Series levers and trim?
Yes, within the ND Series. The ND25X70L is built on the Schlage ND platform and is meant to drop into an existing ND lock assembly, so ND levers, roses and escutcheons mate to it. It is not a substitute for an L Series mortise lock or an AL Series chassis, which use different bodies entirely.
4) Does the ND25X70L chassis come finished to match my other door hardware?
No. It ships unfinished, so it is not a finish match for anything on its own. That is intentional on a chassis, because the finish a building sees comes from the ND lever, rose and escutcheon trim that goes over it. Pick your finish on the trim side and the chassis underneath stays out of sight.
5) Is the Schlage ND25X70L rated for high traffic commercial openings?
It is built to ANSI/BHMA Grade 1, the highest commercial rating, and is designated commercial rather than residential. Grade 1 is the level typically specified for schools, hospitals and high-traffic corridors, which is where a classroom exit lock normally lives.
6) Should I replace the whole lock or just buy the ND25 chassis?
If the lever trim and finish on the door are still in good shape and only the internal mechanism has failed, the chassis alone restores the opening without pulling a full lockset off the wall. If the trim is worn or you are changing finish or lever style, order a complete ND lockset instead, since this chassis arrives with no trim and no finish.
7) What is the full Schlage model designation I should quote for this chassis?
Order it as ND25X70L LLL XXX LLL LLL. The ND25 is the classroom exit function within the ND Series, and the trailing segments reflect the less-parts, unfinished configuration. Quoting the whole string keeps it from being confused with a complete ND25 lockset.
