Schlage 09-639N 619 KN – Frequently Asked Questions

1) What exactly is the Schlage 09-639N KN, and does it include the lock?
It is the outside trim plate only. The 09-639N KN is a full face cylinder by knob N escutcheon for Schlage L Series mortise locksets, finished in satin nickel. It covers the lock prep on the door face and carries the cylinder opening and the knob hub, but no lock body, no cylinder, no knob and no latch come with it. Order those separately if you are replacing more than the trim.
2) Do I need the knob N version specifically, or will any L Series escutcheon work?
You need trim that matches your lever or knob style and the cylinder arrangement. This one is cut for a full face cylinder with knob N trim. An escutcheon prepped for a lever, or for a lock with no cylinder on that side, has a different hub and face pattern and will leave the prep exposed. Check what is on the door now before ordering.
3) Can a Schlage Electronics CO Series exterior escutcheon be used in place of the 09-639N KN on an L Series mortise lock?
No. The 09-639N KN is a full face cylinder x knob N escutcheon trim made for Schlage L Series exterior mortise locksets, a purely mechanical trim plate that covers the lock mechanism and carries the cylinder and knob. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for CO100 cylindrical and mortise locks and is a keypad unit, so it belongs to the CO electronic access control platform rather than L Series mechanical trim. The two are not interchangeable on an L Series opening.
4) Is this the outside plate or the inside plate?
Outside. The 09-639N KN is the exterior escutcheon, which is why it carries the full face cylinder opening. If you are replacing damaged trim on both sides of an L Series opening, you need the matching interior escutcheon as a separate item.
5) What does the 639N finish look like next to 626 satin chrome on my other doors?
639N is satin nickel plated with a clear coat, a warmer, slightly yellower grey than 626 satin chrome. They read as different finishes side by side on the same opening, so if your building is standardized on 626 you should not mix this one in on a visible face. The clear coat is there for corrosion resistance and to hold the appearance.
6) What is the difference between the two CO Series escutcheons if neither of them fits my L Series lock?
They differ by what they mount to. The Schlage Electronics 47260707 is the CO Series exterior escutcheon for CO100 cylindrical and mortise locks, shipped with fasteners and an O-ring. The 47260708 is the CO-100 exterior escutcheon for exit trim and is listed in an aged bronze finish. Both are keypad units. The 09-639N KN is a separate item entirely, a mechanical full face cylinder x knob N trim for Schlage L Series exterior locksets in a satin nickel plated clear coated finish.
7) Our specifier called out stainless escutcheon plates. Is the 09-639N the same kind of part?
Not necessarily. The 09-639N KN is lockset trim: a full face cylinder x knob N escutcheon for Schlage L Series exterior mortise locksets, prepped to carry a cylinder and knob. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it dresses a push switch opening rather than a lock. Confirm whether the drawing is calling for lock trim or a switch plate before ordering.
8) Is this rated for high traffic commercial use or is it a residential part?
Commercial. The 09-639N is catalogued as a commercial-grade Schlage replacement part and is used on office buildings, schools, healthcare facilities and government buildings running L Series mortise hardware. It is not a residential-duty trim.
9) I manage a building with matching Schlage mortise locks. Is this a genuine Schlage part or an aftermarket copy?
Genuine Schlage. It is sold as an OEM replacement component, so the face profile, hole pattern and finish match the original trim on the rest of your L Series openings. That matters when you are replacing one damaged plate in a run of doors that all have to look alike.
