Sargent 77-3435 20D – Frequently Asked Questions

1) What exactly is the Sargent 77-3435 20D, and does it include the lever or the lock body?
The 77-3435 20D is the inside (interior-facing) escutcheon plate for a Sargent 8200 Series mortise lock, supplied in the Turn Lever Only configuration with the LW1/KW1 design. It is the trim plate that houses the interior turn lever. It is not the mortise lock case, and it is not an outside trim assembly. Order it when the interior plate on an existing 8200 is damaged, mismatched, or missing.
2) Will this escutcheon fit a Sargent 8200 Series mortise lock I already have in the door?
Yes. The 77-3435 is built to Sargent's original specifications for the 8200 Series mortise lock and is intended as a direct replacement inside escutcheon on that platform. It is made for the 8200 only, so it should not be ordered for other Sargent mortise families or for cylindrical locks.
3) Can a Schlage CO Series escutcheon be used in place of the Sargent 77-3435 inside escutcheon?
No. The Sargent 77-3435 20D is a mechanical inside escutcheon built for the Sargent 8200 Series mortise lock, with a turn lever only in the LW1/KW1 design. The Schlage Electronics 47260707 is an exterior escutcheon with a keypad for CO100 cylindrical and mortise locks, so it is an outside keypad reader housing rather than an interior turn lever plate, and it is not made to the Sargent 8200 Series pattern. Stay with the Sargent part when servicing an 8200 mortise assembly.
4) My opening needs keypad access rather than a mechanical turn lever - what should I look at instead of the Sargent 77-3435?
The Sargent 77-3435 20D is a turn lever only interior escutcheon, so it provides an interior release and no credential entry. For a keypad-based opening, Schlage Electronics offers the 47260707 exterior escutcheon for CO100 cylindrical and mortise locks with keypad, fasteners and O-ring, and the 47260708 exterior keypad escutcheon for CO-100 exit trim in Aged Bronze. Those are exterior trims for Schlage CO platforms, so the underlying lock or exit device has to be a CO Series unit rather than a Sargent 8200 mortise.
5) What does the LW1/KW1 designation mean when I am ordering a Sargent 8200 escutcheon?
LW1/KW1 is the trim design family on the 8200 Series, and it has to match the rest of the trim on the opening or the plate profile will not look or line up right with the existing lever and outside escutcheon. On this part the interior face carries a turn lever only, with no cylinder provision on that side, so it suits interior release without a key on the inside.
6) What finish does the Sargent 77-3435 come in, and will it match my other dark bronze doors?
One finish: 20D Dark Bronze Painted, sold as 690 Dark Bronze. It matches other 20D/690 Sargent trim on the same opening. If your other doors are plated oil-rubbed bronze rather than painted dark bronze, expect a visible difference in sheen, so compare against an existing plate before standardizing a floor on it.
7) Can I use this Sargent escutcheon to convert a keyed inside trim to a thumbturn?
Not on its own. This plate is the Turn Lever Only version of the 8200 inside escutcheon, so it provides the interior turn lever and no cylinder opening on that face. Whether it works as a conversion depends on the function of the mortise case already in the door; the plate does not change the lock function by itself. Match the escutcheon to the function the 8200 case is built for.
8) I need a bronze escutcheon to match other doors - is the Schlage 47260708 in Aged Bronze an alternative to the Sargent 77-3435 20D?
They are not interchangeable despite both being bronze-toned. The Sargent 77-3435 comes in Dark Bronze Painted (20D) and mounts as the interior escutcheon on an 8200 Series mortise lock with a turn lever. The Schlage Electronics 47260708 in Aged Bronze is an exterior keypad escutcheon for CO-100 exit trim, so it serves electronic exit device trim rather than a Sargent mortise lock. If the goal is finish consistency across Sargent 8200 mortise doors, the 77-3435 20D is the part that keeps both fit and appearance.
9) What is the difference between a decorative escutcheon plate like the MS Sedco ESC and the Sargent 77-3435?
The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it trims a wall switch opening and carries no lock function. The Sargent 77-3435 20D is a functional lock component: the interior escutcheon for a Sargent 8200 Series mortise lock, housing a turn lever for interior release in the LW1/KW1 design. A switch escutcheon will not mount to a mortise lock body or operate a latch.
10) Is the Sargent 77-3435 escutcheon rated for commercial traffic or is it a residential part?
It is a commercial part. The 8200 Series is Sargent's commercial mortise platform, and this escutcheon is specified for commercial door hardware use, which is why it turns up in offices, schools, hospitals, government buildings, and multi-tenant properties.
