Schlage ND66L LLL XXX LLL LLL – Frequently Asked Questions

1) What exactly comes in the Schlage ND66L chassis order, and what do I still need to buy?
The ND66L ships as the bare store lock chassis only, less all possible parts and unfinished. No levers or trim, no cylinder, no finish applied. You supply the ND Series trim, the cylinder, and any keying separately. It is sold as a replacement part for rebuilding or custom assembly of an ND Series store lock, not as a complete lockset.
2) How does the Schlage ND66L store lock function actually work on a retail door?
Store lock function means the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. On a storefront you key the outside lever locked at close of business and staff can still get out from the inside at any time. That egress behavior is why it suits retail, office, and institutional openings.
3) Will the ND66L chassis work with the Schlage ND Series levers and roses already on my doors?
Yes. The chassis is engineered for the Schlage ND Series lockset platform and takes genuine ND Series trim and accessories. If your existing doors are already ND Series, you can reuse the levers and roses and replace only the worn chassis, which is the usual reason facilities buy this part.
4) Is the ND66L chassis heavy-duty enough for a high traffic commercial entry?
It is built to ANSI/BHMA Grade 1, the highest commercial durability tier for bored locks, and the ND Series is a commercial platform. That is the rating specifiers call for on high traffic openings such as school corridors, healthcare facilities, and municipal buildings.
5) Why would I buy just the chassis instead of a whole new ND66 lockset?
Because the chassis is the part that wears out. When the trim and finish on the door are still good and match the rest of the building, swapping the chassis alone keeps the opening consistent and avoids paying for hardware you already have. The unfinished state is not a problem here, since the visible finish lives on the trim you are keeping.
6) Does the unfinished ND66L chassis mean I have to paint or plate it to match my building's finish?
No. The chassis sits inside the door and is hidden by the trim. Unfinished simply means no plating was applied to a component nobody sees, so it can be paired with trim in whatever finish your hardware program uses. Match the finish on the levers and roses you order with it.
7) Is a store lock function the right choice, or should I use an office or classroom function instead?
Store lock, the ND66 function, is keyed from the outside only with permanently free inside egress, so it fits retail and tenant entries where one person locks up with a key. If you want staff to secure the door from the inside without a key, an office function is the better fit; if you want the outside lever locked and unlocked by key with the inside lever free but the lock held in state, a classroom function is the usual call. All three are ND Series bored locks on the same platform.
8) What is the correct Schlage part designation to order for this store lock chassis?
Order it as ND66L LLL XXX LLL LLL. The ND66 prefix is the store lock function and the L designations cover the less-parts, unfinished configuration. Quote that full string when matching an existing ND Series opening so you get the chassis and not a complete lockset.
