Schlage ND12 LLL XXX LLL LLL – Frequently Asked Questions

1) What exactly comes in the Schlage ND12 exit lock chassis order, and what do I still need to buy?
You get the lock chassis by itself. The ND12 is supplied less all possible parts, so no trim, no levers, no roses, no cylinder and no ancillary components are included. If you are rebuilding an ND Series exit lock, plan on sourcing the trim and cylinder separately and reusing or ordering the rest. It ships unfinished, so there is no finish to match on the chassis itself.
2) Will the ND12 chassis work in any Schlage ND Series lockset?
It is built for the Schlage ND Series lock platform and is intended for compatible ND Series exit lock assemblies, not as a universal ND chassis. The ND12 is the exit lock function, so match it to an ND12 opening rather than dropping it into a storeroom, classroom or office ND lock. If the existing lock is a different ND function, the chassis for that function is the part to order.
3) Is the Schlage ND12 chassis rated for high-traffic commercial doors?
Yes. The ND12 chassis is built to ANSI/BHMA Grade 1, the heavy-duty commercial level, and it is catalogued for commercial rather than residential use. That makes it appropriate for school, healthcare, office and government openings where the lock sees constant cycling.
4) The chassis is unfinished. Will that show once it is installed?
No. The chassis sits inside the door behind the roses and trim, so the unfinished surface is hidden once the lever trim goes on. Finish selection happens on the trim you pair with it, which is why the chassis is supplied unfinished and carries no finish conflict with the existing hardware.
5) Should I replace just the chassis or the whole ND12 lockset?
If the trim, roses and cylinder on the door are sound and only the internal mechanism has failed, the chassis alone is the targeted fix. The ND12 is sold specifically for that kind of service and repair work, letting you rebuild the assembly rather than pull a complete lock. If the trim is worn or the finish no longer matches the rest of the building, a full lockset makes more sense.
6) Is this a genuine Schlage part or an aftermarket copy?
It is a genuine Schlage ND Series component manufactured to OEM specification, not an aftermarket equivalent. For facilities standardized on Schlage ND hardware, that keeps the rebuilt lock within the same platform the rest of the openings use.
