Sargent 77-3427 10B – Frequently Asked Questions

1) What exactly is the Sargent 77-3427 part, and is a lock included?
The 77-3427 is an inside escutcheon plate only, a genuine Sargent replacement part for LW1/KW1 commercial mechanical lock assemblies. It is the trim plate that covers the interior face of the door around the lock area. No lock body, no cylinder, no lever or knob comes with it, so if the lock itself has failed you need the lock assembly, not this plate.
2) Why is the Sargent 77-3427 escutcheon blank with no keyhole?
Blank means the face has no cylinder or keyway cutout. It is the inside plate, where a key is not used, so the surface stays uninterrupted. If the plate you are replacing has a cylinder opening in it, that is the outside escutcheon and the 77-3427 is not the match.
3) Will the 77-3427 escutcheon work on Sargent locks with an LW1 or KW1 keyway?
Yes. Sargent lists the 77-3427 as compatible with LW1 and KW1 keyway configurations in their commercial mechanical lock systems. It is built to Sargent's own specifications, so the fit and alignment match the factory plate you are taking off.
4) Is the Schlage Electronics 47260707 CO Series exterior escutcheon an alternative to the Sargent 77-3427?
No. The Sargent 77-3427 is a blank inside escutcheon, a replacement part for Sargent commercial mechanical lock systems with LW1/KW1 keyway configurations, and its face is blank by design for the interior side of the door. 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. One is a plain interior trim plate for a mechanical lock, the other is exterior keypad trim for an electronic access control lock, so they are not interchangeable on the same opening.
5) What finishes does the Sargent 77-3427 inside escutcheon come in?
Eleven finishes, so you can match the rest of the openings in the building: 03 bright brass clear coated, 04 satin brass clear coated, 09 bright bronze clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 15 satin nickel plated clear coated, 20D dark statuary bronze lacquered, 26 bright chromium over nickel, 32 bright stainless, and 32D satin stainless. For most commercial corridors 26D-family satin finishes and 32D satin stainless are the common standard; order the finish code that is stamped or specified on your existing Sargent hardware.
6) I manage a building with Sargent locks on every door. Can I use this to fix scratched interior trim without replacing the lock?
That is exactly what this part is for. Swapping the inside escutcheon restores the interior appearance without touching the lock body or rekeying anything, provided the lock is an LW1/KW1 Sargent assembly. Order the same finish code across the doors so the corridor stays consistent.
7) Can I use an MS Sedco ESC escutcheon plate to cover the interior side of a Sargent lock?
No. The MS Sedco ESC is a decorative stainless escutcheon plate made for R4 and R6 round switches, so it is a trim ring for a push switch rather than lock trim. The Sargent 77-3427 is a blank inside escutcheon built as a genuine replacement part for Sargent commercial mechanical lock systems with LW1/KW1 keyways, and it is the part that keeps the fit, alignment, and finish match on a Sargent lock assembly. It comes in eleven finishes including 26 bright chromium plated over nickel, 32D satin stainless steel, and 10B dark oxidized satin bronze oil rubbed.
8) Is the Sargent 77-3427 escutcheon suitable for a house, or is it commercial only?
It is a commercial part. Sargent classifies the 77-3427 as commercial door hardware, and it is intended for Sargent commercial mechanical lock assemblies found in offices, schools, healthcare, government buildings, retail and multi-tenant residential. It will not fit residential-grade knob or lever sets from other makers.
9) I need an escutcheon for a push-plate switch, not a lock. Is this the right part?
No, the Sargent 77-3427 is lock trim. For a round push switch you want the MS Sedco ESC decorative stainless escutcheon plate, which is made for R4 and R6 round switches. Two different jobs entirely.
