Schlage 09-633N 626 KN – Frequently Asked Questions

1) What exactly is the Schlage 09-633N KN, and what part of the lock does it replace?
The 09-633N KN is the interior trim plate assembly for a Schlage L Series mortise lock: an N-style escutcheon carrying a thumbturn on one side and a knob on the other. It is the visible plate and turn hardware on the door, not the mortise lock case itself. If your lock body is fine but the escutcheon is damaged, worn, or the wrong finish, this is the piece you order.
2) Will the 09-633N KN escutcheon fit a Schlage L Series mortise lock I already have installed?
It is a factory Schlage component built to OEM spec for L Series interior mortise lock assemblies, so it goes onto an existing compatible L Series installation without modifying the door. Confirm your opening is set up for thumbturn-by-knob trim with the N escutcheon shape, since a different trim style (lever trim, or a plain escutcheon with no thumbturn) uses a different part.
3) Does the 09-633N KN include the mortise lock body, cylinder, or spindle?
No. This is the escutcheon trim only, catalogued as a replacement part, with the thumbturn and knob configuration on the N escutcheon. The mortise case, cylinder, and any strike or fasteners beyond what ships with the trim are separate orders. If you are building a complete opening rather than repairing one, order the L Series mortise lock with the trim specified on it.
4) Can a Schlage Electronics 47260707 CO Series escutcheon be used in place of the 09-633N KN thumbturn x knob escutcheon?
No. The 09-633N KN is a mechanical thumbturn x knob escutcheon trim made for Schlage L Series interior mortise lock assemblies. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for CO100 cylindrical and mortise locks with a keypad, supplied with fasteners and an O-ring. One is mechanical interior trim; the other is the keypad-carrying exterior housing of an access control lock, so they serve different sides and different lock platforms.
5) We are replacing escutcheon trim on an exit device, not a mortise lock. Is the 09-633N KN the right part?
No. The 09-633N KN is interior trim for Schlage L Series mortise lock assemblies and carries a thumbturn on one side and a knob on the other. For exit trim, the Schlage Electronics 47260708 is a CO Series exterior escutcheon made specifically for exit trim on CO-100 keypad applications and comes in an aged bronze finish. Confirm whether your opening uses a mortise lock body or an exit device before ordering either.
6) What finishes does the Schlage 09-633N escutcheon come in for matching the rest of my doors?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless, and 630 satin stainless. For a building already standardized on Schlage, match the BHMA number stamped or specified on your existing trim rather than the color name, since 626 satin chrome and 630 satin stainless look similar but are not the same finish.
7) Is the MS Sedco ESC escutcheon plate an alternative to the Schlage 09-633N KN?
No. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, part of a switch line rather than door lock hardware. The Schlage 09-633N KN is a commercial-grade replacement escutcheon that carries a thumbturn and a knob for Schlage L Series interior mortise locks. The two share only the word escutcheon; they mount to entirely different devices.
8) Our finish schedule calls for satin chrome escutcheons. Which of these escutcheon options can meet that?
The Schlage 09-633N KN thumbturn x knob escutcheon is offered in 626 satin chrome, along with 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 629 bright stainless steel, and 630 satin stainless steel. By contrast, the Schlage Electronics 47260708 CO Series exit trim escutcheon is an aged bronze finish part. If the schedule is standardized on satin chrome mortise trim, the 09-633N KN covers it.
9) Can I use the 09-633N KN as a cover plate over an unused hole or a push-button switch?
No. It is functional lock trim with a working thumbturn and knob for an L Series mortise lock, not a blank cover. For dressing up a round push switch, the MS Sedco ESC is a decorative stainless escutcheon plate made for R4 and R6 round switches.
10) Should I buy genuine Schlage trim or will aftermarket escutcheons work on an L Series?
For an L Series repair, use the factory part. The 09-633N KN is a genuine Schlage component made to OEM specifications so it drops onto the existing assembly without modification and keeps the lock operating as originally built. Aftermarket plates commonly differ in screw pattern and thumbturn spindle engagement, which turns a ten-minute swap into a door prep job.
