Sargent 77-3448 10 – Frequently Asked Questions

1) Is the 77-3448 the inside or the outside trim plate?
Outside only. It is the exterior-facing escutcheon that houses the keyway on an 8200 Series mortise lock. If the plate you are replacing is on the room side, this is the wrong half of the pair.
2) Does the 77-3448 escutcheon take a thumbturn?
No. The 77-3448 is the knob/lever-only configuration, with no thumbturn cutout. Openings that need an outside thumbturn require the thumbturn version of the 8200 outside escutcheon instead.
3) Can I just replace the escutcheon plate instead of the whole mortise lock?
That is exactly what this part is for. The 77-3448 is an OEM replacement component, so a damaged, worn, or wrong-finish outside plate on an existing 8200 mortise installation can be swapped without pulling and replacing the lock body. It suits service techs and facility maintenance keeping existing Sargent openings in commercial buildings, schools, healthcare, and multi-tenant residential running.
4) Can a Schlage CO Series exterior escutcheon be used in place of a Sargent 77-3448 on an 8200 mortise lock?
No. The Sargent 77-3448 is a mechanical replacement escutcheon for the Sargent 8200 Series mortise lock, built for knob or lever trim with an LW1/KW1 keyway design. The Schlage Electronics 47260707 is a CO Series exterior escutcheon with a keypad function, intended for CO100 cylindrical and mortise electronic locks and supplied with fasteners and an O-ring. The keypad escutcheon carries credential entry electronics and matches the CO Series chassis, so it will not mount to or operate an 8200 mortise lock. For a mechanical 8200 opening, the 77-3448 is the correct part.
5) What does the LW1/KW1 design on this Sargent escutcheon mean for my cylinder?
LW1/KW1 is the lever/knob trim design for the 8200 Series, and the escutcheon is machined to accept the matching cylinder and key system used on that platform. The plate carries the cylinder opening; it does not include a cylinder, so reuse the one from the lock you are servicing or order one separately keyed to your system.
6) What finishes does the Sargent 77-3448 outside escutcheon come in?
Eleven finishes, so you can match what is already on the other doors: 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, 26 bright chrome over nickel, 26D satin chrome over nickel, 32 bright stainless, and 32D satin stainless. Property managers standardizing a building usually land on 26D or 32D.
7) Does the knob or lever come with the 77-3448 escutcheon?
No. This is the escutcheon plate alone, configured for knob or lever trim. The lever or knob, the cylinder, and the mortise lock body are all separate items, so order any of those you are not reusing from the existing door.
8) Will a Schlage CO Series escutcheon work as a substitute for this Sargent plate?
No. The Schlage Electronics 47260707 and 47260708 CO Series exterior escutcheons are keypad units for electronic CO-100 cylindrical, mortise, and exit trim locks, not mechanical trim for a Sargent 8200 body. If you are servicing a Sargent 8200 mortise lock, the 77-3448 is the matching plate; the Schlage parts belong on Schlage CO Series hardware.
9) What is the difference between an escutcheon for exit device trim and the Sargent 77-3448?
They serve different door hardware platforms. The Sargent 77-3448 is the outside escutcheon for the Sargent 8200 Series mortise lock, configured for knob or lever trim without a thumbturn. The Schlage Electronics 47260708 is a CO-100 keypad escutcheon made for exit device trim and offered in an aged bronze finish, so it mounts to an exit device rather than a mortise lock case. If the opening has a mortise lock body in the door, the 77-3448 is the matching trim; if it has a rim or mortise exit device with electronic trim, the exit trim escutcheon is the one that fits.
10) I need a stainless escutcheon plate to trim out a round push switch, not a lock. Is the Sargent 77-3448 right?
No. The Sargent 77-3448 is a commercial replacement part for a mortise lock, housing the keyway and knob or lever trim on the outside face of a Sargent 8200 Series lock. For dressing a round actuator switch, the MS Sedco ESC is a decorative stainless escutcheon plate made for R4 and R6 round switches. The two are not interchangeable in either direction.
11) We are standardizing door finishes across a building - does the Sargent 77-3448 escutcheon come in enough finishes to match a mixed hardware set?
Yes. The Sargent 77-3448 outside escutcheon is offered in 11 finishes, including 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, 26 bright chromium plated over nickel, 26D satin chromium plated over nickel, 32 bright stainless steel, and 32D satin stainless steel. By contrast, the Schlage Electronics 47260708 CO Series exit trim escutcheon is a keypad unit cataloged in aged bronze. If a facility is matching existing Sargent mortise trim across several openings, the 77-3448 finish range covers the common commercial brass, bronze, chrome, and stainless options.
12) Is the 77-3448 escutcheon rated for high-traffic commercial doors?
It is a commercial part, built to Sargent's 8200 Series standards rather than a residential trim plate, and it is used in office buildings, schools, healthcare, retail, government, and industrial facilities.
