Sargent 77-3432 20D – Frequently Asked Questions

1) Will the Sargent 77-3432 escutcheon fit my 8200 Series mortise lock without modifying the door?
Yes. The 77-3432 is a genuine Sargent inside escutcheon built for the 8200 Series mortise lock, so it drops onto existing 8200 prep with no modification. It is the interior-facing trim plate only, not the lock body, so the mortise case and cylinder already in the door stay in place.
2) Is the Sargent 77-3432 the lock itself or just the trim plate?
It is the plate, not the lock. The 77-3432 is an inside escutcheon, a replacement trim part for an 8200 Series mortise lock. Ordering it does not get you a mortise case, latch, cylinder, knob, or lever, so if the lock body itself has failed you need the mortise lock, not this part.
3) What does the LW1/KW1 designation on this Sargent escutcheon mean for my trim?
LW1 and KW1 are Sargent's lever and knob trim designs, and the 77-3432 is cut for that design family with a turn lever opening on the inside. That means it accepts a knob/lever plus the inside turn lever (thumbturn) used on functions like office and classroom. If your inside trim is a different Sargent design series, the escutcheon cutouts will not match.
4) Can a Schlage CO Series exterior escutcheon be used in place of the Sargent 77-3432 inside escutcheon?
No. The Sargent 77-3432 is the interior-side escutcheon for the Sargent 8200 Series mortise lock, supporting knob/lever and turn lever trim with LW1/KW1 design. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks on the CO100 with a keypad, supplied with fasteners and an O-ring. One is mechanical interior trim on a Sargent 8200 chassis, the other is the outside keypad housing of an electronic CO Series lock, so they are not interchangeable in either direction.
5) What finish is the Sargent 77-3432 escutcheon, and will it match my other doors?
It comes in 690 Dark Bronze, a painted dark bronze finish. It will blend with other 690 painted bronze Sargent trim on the same opening or corridor. If your existing escutcheons are 613 oil rubbed bronze or 10B, expect a visible difference in tone and sheen, since 690 is a paint rather than a plated or oiled finish.
6) Do I need to order the outside escutcheon too when replacing the inside one?
Not necessarily. The 77-3432 covers the inside of the door only. If the outside plate is undamaged and already 690 dark bronze, the inside plate alone restores the opening. Replace both when the outside is also worn or when you are changing finish, since a new painted plate beside an aged one will show.
7) How do I confirm I am ordering the right Sargent escutcheon part number?
Order by model 77-3432 20D. The 77-3432 identifies the inside escutcheon for the 8200 Series in the LW1/KW1 design with knob/lever and turn lever; the 20D suffix is the dark bronze painted finish, shown as 690 on the finish option.
8) Is the MS Sedco ESC escutcheon plate a substitute for the Sargent 77-3432?
No. 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 switch rather than a lock. The Sargent 77-3432 is a replacement inside escutcheon for the Sargent 8200 Series mortise lock with knob/lever and turn lever provisions. They cover different openings in the door and share no prep.
9) Is this Sargent escutcheon rated for high-traffic commercial use like schools and hospitals?
It is a commercial part, used on 8200 Series openings in office buildings, schools, healthcare facilities, government buildings, multi-tenant residential, retail, and industrial sites. As an OEM Sargent component it carries the same trim as the original installation, which is what keeps a standardized facility consistent when you repair one door out of many.
