Sargent 77-3448 20D – Frequently Asked Questions

1) What exactly is the Sargent 77-3448, and what does it replace?
The 77-3448 is the outside escutcheon plate for a Sargent 8200 Series mortise lock, not the lock itself. It is the trim plate that mounts on the outside face of the door and carries the knob or lever. Sargent sells it as an OEM replacement part, so it is what you order when the plate is damaged, mismatched, or refinished and the mortise case itself is fine.
2) Does the Sargent 77-3448 escutcheon have a cylinder hole?
No. The 77-3448 is the knob/lever-only version, with no cylinder cutout. It suits passage and other non-keyed outside trim configurations. If the opening needs a keyed outside cylinder, this plate will not accept one and you need the cylinder-prepped escutcheon for that 8200 function instead.
3) Can a Schlage CO Series exterior escutcheon be used to replace a Sargent 77-3448 on an 8200 mortise lock?
No. The Sargent 77-3448 is a mechanical outside escutcheon built for the Sargent 8200 Series mortise lock in an LW1/KW1 design, accepting knob or lever trim with no cylinder cutout. The Schlage Electronics 47260707 is a CO Series exterior escutcheon with an integral keypad, supplied with fasteners and an O-ring, and is part of an electronic access control trim rather than mechanical knob or lever trim. The two serve different lock platforms and different trim functions, so one does not stand in for the other.
4) What does the LW1/KW1 designation on the Sargent 77-3448 escutcheon mean?
LW1 and KW1 are the Sargent 8200 Series trim designs, LW1 being the lever design and KW1 the knob design. The 77-3448 escutcheon is the plate shape used with those designs, so it is the one to order if the other doors in the building already carry LW1 levers or KW1 knobs on 8200 mortise locks.
5) What finish does the Sargent 77-3448 escutcheon come in, and will it match my other 8200 trim?
One finish only: Dark Bronze Painted, Sargent code 20D, which corresponds to 690 in the BHMA numbering. It is a painted factory finish, so it matches other 20D/690 painted bronze Sargent trim rather than an oil-rubbed or plated bronze. If your existing plates are 10B or 613 oil-rubbed, expect a visible difference.
6) Can I use the Sargent 77-3448 on the inside of the door too?
No. This is specifically the outside escutcheon position on an 8200 Series mortise assembly. Inside trim uses its own plate, so order the inside escutcheon separately if that is the side you are restoring.
7) Does the Sargent 77-3448 escutcheon come with the knob or lever?
No. The 77-3448 is the escutcheon plate alone. The knob or lever in the matching LW1 or KW1 design is a separate order, as is any cylinder, since this plate takes no cylinder at all.
8) If I want to add keypad access to the opening instead of replacing the Sargent 77-3448 mechanical trim, what escutcheons cover that?
Moving from mechanical knob or lever trim to keypad access means changing the trim platform rather than swapping escutcheons on the 8200 mortise lock. For Schlage Electronics CO Series openings, the 47260707 is a CO100 exterior keypad escutcheon for cylindrical and mortise locks and ships with fasteners and an O-ring, while the 47260708 is the CO-100 exterior keypad escutcheon for exit trim in Aged Bronze. The Sargent 77-3448 remains the part for keeping the opening mechanical with knob or lever trim and no cylinder cutout.
9) I need a dark bronze escutcheon to match existing hardware - is the Schlage 47260708 in aged bronze an alternative to the Sargent 77-3448?
They are not interchangeable despite both being bronze-tone escutcheons. The Sargent 77-3448 carries a factory Dark Bronze Painted (20D) finish and mounts in the outside escutcheon position of an 8200 Series mortise lockset. The Schlage Electronics 47260708 in Aged Bronze is a CO-100 keypad escutcheon made for exit trim, so it fits an exit device rather than a mortise lockset and adds a keypad to the opening. If the goal is restoring a Sargent 8200 mortise lock with knob or lever trim, the 77-3448 is the matching part.
10) Will a decorative stainless escutcheon plate work in place of the Sargent 77-3448 mortise lock escutcheon?
No. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it is a cover plate for a push-switch actuator, not lock trim. The Sargent 77-3448 is a commercial replacement escutcheon that carries knob or lever trim on a Sargent 8200 Series mortise lock in an LW1/KW1 design. A switch trim plate has no spindle or trim provisions and cannot be fitted to a mortise lockset.
11) Is the 77-3448 escutcheon rated for commercial traffic, or is it a residential part?
It is a commercial part. Sargent builds the 77-3448 to the same standards as the original 8200 Series mortise lock trim, which is why it shows up on office buildings, schools, hospitals, government buildings, retail, and multi-tenant residential where the doors see heavy daily use.
