Sargent 77-3428 10B – Frequently Asked Questions

1) What exactly is the Sargent 77-3428 part, and does it include the knob or lever?
The 77-3428 is the inside escutcheon plate only, for Sargent LW1 lever and KW1 knob trim. It is the interior-facing plate the trim mounts through, and no knob, lever, cylinder, or lock body comes with it. If your lock body is fine and only the plate is damaged or mismatched in finish, this is the piece to order; if the lever itself is broken you need the lever separately.
2) Will the Sargent 77-3428 escutcheon work on trim other than LW1 or KW1?
No. It is made specifically for LW1 lever and KW1 knob trim styles, and the fit is to those configurations. If your Sargent trim carries a different designation, order the escutcheon called out for that trim rather than the 77-3428.
3) Can I get the Sargent 77-3428 inside escutcheon in a finish that matches the rest of my building's doors?
Eleven Sargent finishes are offered: 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. Match the finish code stamped or specified on the existing Sargent trim so the repaired opening does not stand out from the others.
4) Is the 77-3428 the inside or the outside escutcheon?
Inside only. It covers the interior face of the door. An outside plate for the same opening is a separate part number, so if both faces are damaged you are ordering two pieces.
5) Can a Schlage CO Series escutcheon be used in place of the Sargent 77-3428 inside escutcheon?
No. The Sargent 77-3428 is a mechanical lock replacement part made for LW1 lever and KW1 knob trim, serving as the interior-facing escutcheon plate. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks in a keypad configuration, supplied with fasteners and an O-ring. One is interior mechanical trim for a Sargent lockset, the other is an exterior electronic keypad housing, so they are not interchangeable. To restore Sargent LW1/KW1 trim, stay with the 77-3428.
6) Is this escutcheon suitable for a school or hospital door, or is it residential-grade?
It is a commercial-grade component, built for the same institutional service as the Sargent locks it goes on: offices, schools, healthcare, government buildings, multi-tenant residential, retail, and industrial facilities. It is genuine Sargent parts stock, not an aftermarket lookalike.
7) Do I have to replace the whole Sargent lockset if the inside plate is scratched or bent?
Not if the lock body and trim are still serviceable. Swapping in the 77-3428 inside escutcheon restores the interior appearance and the trim mounting without pulling the lock, which is the usual approach for property managers keeping a floor of Sargent openings looking uniform on an MRO budget.
8) Is the Sargent 77-3428 an electronic or keypad escutcheon?
No, it is a plain mechanical trim plate for Sargent mechanical lock hardware, with no keypad, credential reader, or wiring. If you need an electronic escutcheon, the Schlage Electronics 47260707 CO Series exterior escutcheon for cylindrical and mortise locks is a keypad unit, and the 47260708 is the keypad escutcheon for CO-100 exit trim in aged bronze.
9) I need an escutcheon in a dark bronze tone for a Sargent lever - is the Schlage 47260708 in Aged Bronze an option?
The Schlage Electronics 47260708 is a CO Series exterior escutcheon for exit trim in a keypad configuration with an Aged Bronze finish, so it belongs on Schlage CO-100 exit device trim rather than on Sargent knob or lever trim. For a dark bronze tone on Sargent LW1/KW1 trim, the 77-3428 is offered in 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 10 satin bronze clear coated, and 20D dark statuary bronze lacquered.
10) Is the MS Sedco ESC escutcheon plate a substitute for a Sargent lock escutcheon?
No. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it trims a push-switch opening, not a lockset. The Sargent 77-3428 is a commercial mechanical lock component that mounts as the inside escutcheon behind LW1 lever or KW1 knob trim. Even in a stainless tone the two serve different preps; the 77-3428 covers stainless with its 32 bright stainless steel and 32D satin stainless steel finishes.
