Sargent 77-3431 26D – Frequently Asked Questions

1) What exactly is the Sargent 77-3431 part, and does it include the cylinder?
The 77-3431 is the inside escutcheon plate only, for Sargent lock assemblies set up with LW1 and KW1 cylinder and turn configurations. It is the trim plate that covers the interior face of the door around the cylinder and turn, not the cylinder, not the turn piece, and not a complete lock. If your cylinder or thumbturn is the damaged item, this plate will not fix it.
2) Will the Sargent 77-3431 escutcheon work with any Sargent lock, or only certain trim?
Only Sargent assemblies using the LW1 or KW1 cylinder and turn configuration. It is a genuine OEM Sargent component made to drop into those existing configurations without modification, so the cutouts line up with that specific cylinder-and-turn arrangement. Pull the old plate and confirm your lock is an LW1 or KW1 setup before ordering.
3) Can a Schlage CO Series exterior escutcheon be used in place of the Sargent 77-3431 inside escutcheon?
No. The Sargent 77-3431 is a mechanical inside escutcheon made for LW1 and KW1 cylinder and turn configurations on Sargent lock assemblies. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks with a keypad, so it is an electronic access control trim for the outside face of the door rather than a mechanical interior plate with a cylinder and turn cutout. They are not interchangeable, and the 77-3431 is the part to order when you are restoring Sargent trim.
4) If the opening uses exit device trim rather than a Sargent lock, what escutcheon applies instead of the 77-3431?
The Sargent 77-3431 is built as a drop-in inside escutcheon for existing Sargent lock configurations with LW1 or KW1 cylinder and turn, so it is not the part for exit device trim. For a keypad exit trim opening, the Schlage Electronics 47260708 is a CO-100 Series exterior escutcheon made specifically for exit trim and supplied in an aged bronze finish. Confirm whether your door carries a Sargent lock body or an exit device before ordering either one.
5) Is the 77-3431 escutcheon suitable for a school or hospital door, or is it residential trim?
It is a commercial-grade part, catalogued for commercial mechanical lock assemblies, and the typical uses run to office buildings, schools, healthcare, retail, government buildings, multi-tenant residential and warehouse facilities. For facilities standardizing on Sargent, it is the OEM plate rather than an aftermarket substitute.
6) Do I have to replace the whole lock if the inside escutcheon is scratched or a tenant damaged it?
No. The 77-3431 is sold as a standalone replacement part and installs as a direct replacement in existing Sargent LW1/KW1 configurations without modification, so a property manager can refresh the interior appearance of a door without touching the cylinder, the latch or the door prep. Order the plate in the finish that matches the rest of the opening.
7) We want to match existing brass and bronze lock trim rather than an electronic keypad escutcheon. Which part fits that?
The Sargent 77-3431 is the one to specify for finish matching on mechanical Sargent trim. It is offered in 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, 20D dark statuary bronze lacquered, 26 bright chromium, 26D satin chromium, 32 bright stainless and 32D satin stainless. By comparison, the Schlage Electronics 47260708 CO-100 exit trim escutcheon is a keypad component supplied in aged bronze.
8) Is an MS Sedco ESC escutcheon plate an alternative to the Sargent 77-3431?
No. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, part of the switches line, so it trims a push-plate or actuator switch rather than a lock. The Sargent 77-3431 is a commercial mechanical lock replacement part that mounts on the interior face of the door around an LW1 or KW1 cylinder and turn. If you are replacing lock trim, the 77-3431 is the correct item; the MS Sedco plate addresses a switch opening.
9) Which side of the door does the Sargent 77-3431 escutcheon go on?
The interior face. It is the inside escutcheon, covering the hardware on the room side and protecting the door surface there. If the plate you are replacing is on the outside of the opening, this is not the part you want.
