Schlage L583-187 626 KN – Frequently Asked Questions

1) What exactly is the Schlage L583-187 KN, the whole lock or just the trim plate?
It's trim only. The L583-187 KN is a concealed cylinder x knob escutcheon plate for Schlage L Series interior mortise lock assemblies, sold as a genuine Schlage replacement part. The mortise lock case, latch, cylinder and knob are separate items. Buy it when the existing L Series lock body is still good and you only need to restore or refinish the visible plate.
2) Will the L583-187 KN fit a Schlage lever-trim L Series lock?
No. This escutcheon is machined for a knob, not a lever. If the door currently has an L Series lever, the hub and plate geometry differ and you need the matching lever escutcheon instead. Confirm the trim on the door is knob-type before ordering.
3) What does "concealed cylinder" mean on this Schlage escutcheon, and will it work on a function with an exposed cylinder?
Concealed cylinder means the plate covers the cylinder so no keyway shows through the trim, which is why it reads clean on a finished commercial door. It is the wrong plate for any L Series function that needs a visible keyway on that side, since there is no cylinder opening to key through. Use it on the interior side of functions where the cylinder sits behind the trim.
4) Can a Schlage Electronics 47260707 CO Series escutcheon be used in place of the L583-187 KN on a mortise lock?
No. The L583-187 KN is a concealed cylinder knob escutcheon made for Schlage L Series mortise lock assemblies, a purely mechanical trim plate with no electronics. The Schlage Electronics 47260707 is a CO Series exterior escutcheon with an integrated keypad for CO-100 cylindrical and mortise locks, supplied with fasteners and an O-ring. The keypad unit is part of an access control lock and carries its own credential reader, so it will not mate to an L Series mechanical mortise case or accept the concealed cylinder arrangement the L583-187 KN is built around.
5) What finishes does the Schlage L583-187 KN knob escutcheon come in?
Eight: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. For a property manager matching existing openings, 626 satin chrome and 630 satin stainless are the usual commercial standards, and the BHMA number stamped or specified on the rest of the lock trim is the safest thing to match to.
6) Can I replace just the escutcheon instead of the whole mortise lock?
Yes, and that's the point of the part. Swapping the L583-187 KN plate restores the appearance and trim of an existing L Series mortise installation without pulling the lock case out of the door, so the door prep, cylinder and keying all stay as they are. Less downtime on an occupied opening and no re-keying.
7) We want keypad entry on a door that currently uses the L583-187 KN escutcheon. What is the alternative?
The L583-187 KN is a mechanical replacement trim for Schlage L Series mortise locks and cannot be converted to electronic entry on its own. For keypad credential entry, Schlage Electronics offers the 47260707 CO Series exterior escutcheon with keypad for CO-100 cylindrical and mortise locks, shipped with fasteners and an O-ring. Note that this is exterior trim for a CO Series lock, so the door needs the matching CO-100 lock assembly rather than an L Series mechanical case.
8) I need a matching finish across a building. How does finish selection on the L583-187 KN compare with the 47260708 escutcheon?
The Schlage L583-187 KN concealed cylinder knob escutcheon is offered across eight architectural finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel, so it can be matched to existing L Series trim on a floor or wing. The Schlage Electronics 47260708 CO Series exit trim escutcheon is an aged bronze finish part. If the standard across the facility is 626 satin chrome or 630 satin stainless, the L583-187 KN covers those directly.
9) Is an MS Sedco ESC escutcheon plate a substitute for a Schlage L583-187 KN?
No. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it trims a push switch rather than a lock. The Schlage L583-187 KN is a commercial concealed cylinder knob escutcheon that mounts to Schlage L Series mortise lock assemblies and carries the knob and concealed cylinder interface. The two share only the word escutcheon; the Sedco plate has no lock prep.
10) Is this escutcheon rated for high-traffic commercial doors or is it a residential part?
It's a commercial part, built for L Series mortise applications in high-traffic settings such as offices, schools, healthcare, retail, government buildings, multi-tenant residential and industrial facilities.
11) Is the L583-187 KN a genuine Schlage part or an aftermarket copy?
Genuine Schlage, made to OEM specification for L Series mortise lock assemblies. That matters on escutcheon trim because the screw pattern and hub location have to line up with the existing lock case; an approximate aftermarket plate usually doesn't.
