Schlage L583-187 626 – Frequently Asked Questions

1) What exactly is the Schlage L583-187 and what part of the lock does it replace?
The L583-187 is the escutcheon plate, not the lock itself. It is the concealed cylinder by lever escutcheon that mounts on the interior side of a Schlage L Series mortise lock and carries the lever trim. You buy it when the plate is damaged, mismatched in finish, or missing, and the mortise lock body stays in the door.
2) Will the L583-187 escutcheon fit a Schlage ND or AL cylindrical lock?
No. The L583-187 is built for Schlage L Series mortise lock assemblies only. ND and AL are cylindrical locksets with completely different trim mounting, so this plate will not mount to them. For a cylindrical opening you need trim made for that lock family.
3) Does the L583-187 escutcheon include a cylinder or a lever?
No, it is the escutcheon plate on its own. The concealed cylinder version means the plate hides the cylinder behind it rather than supplying one. Order your lever trim and any cylinder separately to suit the L Series function you are servicing.
4) I manage a building with Schlage L Series locks - can I just swap the escutcheon without pulling the mortise lock out of the door?
That's the point of the part. The L583-187 is an authentic Schlage replacement component that goes back into an existing L Series configuration without modification, so a damaged or worn interior plate can be changed out while the mortise case stays in the door prep. Useful in schools, healthcare, offices and multi-tenant residential where the locks are standardized and you only want to touch the trim.
5) Will a Schlage Electronics CO Series escutcheon work as a replacement on an L Series mortise lock?
No. The Schlage L583-187 is a concealed cylinder lever escutcheon made for Schlage L Series interior mortise lock assemblies, and it carries no electronics. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks with a keypad, supplied with fasteners and an O-ring, and its function is keypad access rather than mechanical lever trim. Order the L583-187 when you are restoring mechanical L Series trim, and the CO Series part only when the opening already runs CO-100 keypad hardware.
6) Which finishes does the Schlage L583-187 escutcheon come in so I can match my other 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 steel and 630 satin stainless steel. Match the BHMA number stamped or specified on your existing L Series trim rather than eyeballing the color, since 625 and 629 both read bright and 626 and 630 both read satin.
7) I need an escutcheon for exit device trim, not a mortise lever - what should I look at instead?
The L583-187 is built for the lever trim on Schlage L Series interior mortise lock assemblies, so it is not the part for an exit device. For exit trim, the Schlage Electronics 47260708 is a CO Series exterior escutcheon made specifically for exit trim on CO-100 keypad hardware, in an aged bronze finish. Match the part to the device type on the door before ordering.
8) Is an MS Sedco ESC escutcheon plate an alternative to the Schlage L583-187?
No, they serve different devices. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, part of a switches line, so it trims a push-plate or actuator switch rather than a lock. The Schlage L583-187 is a commercial concealed cylinder lever escutcheon for Schlage L Series interior mortise lock assemblies. If the plate you are replacing sits behind a lever on a mortise lock, the L583-187 is the correct family; if it surrounds a round door-activation switch, the MS Sedco plate is.
9) We are standardizing finishes across a building - does the Schlage L583-187 give more finish choice than the CO Series escutcheons?
The L583-187 concealed cylinder lever escutcheon is offered in 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 most existing commercial trim schedules. The Schlage Electronics 47260708 CO Series exit trim escutcheon is specified in aged bronze. If your facility standard is a brass, chrome or stainless BHMA number, the L583-187 covers those directly.
10) Is the L583-187 escutcheon rated for commercial traffic or is it a residential part?
It is a commercial-grade part, built to the same factory standard as the trim shipped on Schlage L Series mortise locks. The typical homes for it are office buildings, schools, hospitals, government facilities, warehouses and retail.
11) Does handing matter when ordering the L583-187 escutcheon?
The L583-187 is the interior-side escutcheon for L Series mortise trim, and what you specify on it is the finish. The lever itself and the mortise lock function are where handing gets set, so confirm the finish number against the rest of the opening and keep the existing lever handing as is.
