Schlage Commercial 09-639 Outside Full Face Cylinder x Trim L Escutcheon & Bushing

Just the outside trim. The 09-639 is the outside escutcheon plate with its bushing for Schlage L Series mortise locks. The cylinder, the knob or lever, and the mortise case itself are all separate items. The plate is made in the full face cylinder x knob/lever pattern, meaning one continuous face carrying both the cylinder opening and the knob/lever hub opening rather than a separate cylinder collar and rose.

No, and it will not adapt. The 09-639 is mortise lock trim for the Schlage L Series. A bored lockset is trimmed with a round rose or a plate built around a 2-1/8 inch cross bore, which is a completely different mounting pattern. Quick way to tell which you have: pull the door open and look at the edge. A rectangular steel case pocketed into the door edge is a mortise lock and this is the right family of trim. A round hole through the door face with a chassis running through it is bored, and you need cylindrical trim instead.

That is what the 09-639 is for. It is a replacement outside escutcheon with bushing for a Schlage L Series mortise lock, so the lock case stays pocketed in the door and the cylinder stays keyed the way it is. You are only pulling the outside trim off the face. No re-mortising, no new door prep, no strike work. Match three things when you order and the new plate drops onto the same prep: the escutcheon design, the knob or lever application, and the finish.

The plate measures 7-7/8 x 2-1/2 x 7/16 inches, so it covers a narrow band of the door face around the cylinder and the hub, not a broad decorative area. If you are coming off a larger plate, expect old fastener holes, unpainted shadow, or a finish ring at the edges of the previous trim to remain exposed. Measure what is currently covered on the door before you commit, especially on a painted or stained door where the old outline will show.

Yes. Knob application and lever application are ordered separately, so specify which handle is going back on the door and the correct bushing comes with the plate. Both share the same full face cylinder x knob/lever escutcheon design, so the visible plate is the same shape either way, but do not assume the two are interchangeable when you place the order. If you are replacing knobs with levers on a retrofit, order the lever application.

Two designs are built: L, the full face escutcheon, and N. The design letter is part of the trim designation on the original hardware schedule for the opening, and it is the thing that has to match across a set of doors if you want the trim to look the same down a corridor. Easiest check on an occupied building is to take the existing plate off one door and put it next to what you are ordering, or pull the trim designation off the schedule if the job records are still around. Ordering the wrong letter gets you a plate that mounts but does not match the neighbouring doors.

626 satin chrome is available, and it is one of eleven: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, 630 satin stainless steel, and 643E aged bronze. Order by the number, not the colour name, since those numbers are the BHMA finish codes and they are what appears on the original hardware schedule. One caution on matching in an occupied building: 613 oil rubbed bronze darkens at handled areas over time, so a new plate on a run of older doors reads brighter until it wears in.

Three variables, and they are the ones that make a spare useless if you get them wrong. Escutcheon design (L full face, or N), application (knob or lever), and finish. The configuration itself is fixed: full face cylinder x knob/lever, commercial duty, for Schlage L Series mortise locks. A facility running one design letter, one handle style, and one finish across its openings only needs a single line item on the shelf. A portfolio with mixed vintages usually needs two or three, so audit a sample of doors per building before you set the stocking level.
