Schlage ND25 LLL XXX LLL LLL – Frequently Asked Questions

1) What exactly comes in the Schlage ND25 chassis part, and what do I still have to buy?
What ships is the bare lock chassis for the ND25 exit lock with deadlatch, supplied less all possible parts and unfinished. That means the core mechanical assembly only, no trim, no roses, no levers, no latch or strike hardware included. It is sold as a replacement part, so anything else the opening needs comes from your own stock or has to be ordered separately as ND Series components. If you are looking for a complete, finished exit lock ready to hang on a door, this is not that item.
2) Will the ND25 chassis work in my existing Schlage ND Series lock assembly?
It is built specifically for the Schlage ND Series lock platform, so it is intended to drop into compatible ND Series assemblies during repair or retrofit. Compatibility outside the ND Series is not something this part claims, so if the lock on the door is an L Series mortise, an AL cylindrical, or another manufacturer's lock, this chassis is the wrong component.
3) Is the Schlage ND25 exit lock chassis Grade 1?
Yes, it is built to ANSI/BHMA Grade 1, which is the heaviest commercial duty level and what most institutional specs call for on high-traffic openings. That matters for schools, healthcare, and government facilities where the hardware schedule names Grade 1 cylindrical locks. The part is classified for commercial use, not residential.
4) Does "unfinished" mean I have to paint or plate this chassis before installing it?
No painting is required. The chassis sits inside the door behind the trim, so finish is not a factor on a normal repair, which is why it is supplied unfinished. The visible finish on the opening comes from the roses and levers you mount over it. If you do want it coated to match something, the unfinished surface will take a field-applied finish.
5) What is a deadlatch chassis and why would I want one on an exit door?
The deadlatch mechanism keeps the latchbolt from being pushed back once the door closes, so the latch stays positively engaged instead of being shimmed or carded open. On an exit lock configuration that is the security piece: free egress from the inside, but the latch cannot be manipulated from the outside. The ND25 uses that deadlatch chassis design.
6) I manage a building standardized on Schlage ND locks. Is buying just the chassis a reasonable way to keep them running?
That is the intended use. Rather than replacing whole lock assemblies, a service tech can swap the ND25 chassis and reuse the existing trim and finish hardware, which keeps the look consistent across doors already carrying ND Series locks. It is sold as an individual replacement component for exactly that repair, retrofit, or re-assembly work.
7) What model number do I order this Schlage chassis under?
The full designation is ND25 LLL XXX LLL LLL, a Schlage ND Series product. The trailing segments reflect that it is supplied less trim and less finish, so quote it to a distributor exactly that way rather than as a plain ND25 lockset, which would be a complete lock.
