Sargent 77-3454 3 – Frequently Asked Questions

1) Does the Sargent 77-3454 escutcheon take LW1 or KW1 keyed cylinders?
Both. The 77-3454 is prepped for the LW1/KW1 keyway, which lets a locksmith key it into an existing Sargent LW1 masterkey system or use a standard KW1 keyway cylinder.
2) Is the Schlage Electronics 47260707 CO Series exterior escutcheon a substitute for the Sargent 77-3454?
No. The Sargent 77-3454 is a mechanical outside escutcheon for the Sargent 8200 Series mortise lock, built around an LW1/KW1 keyway with knob or lever trim and an emergency release. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks with a keypad function, supplied with fasteners and an O-ring. If the opening has a mechanical 8200 mortise lock and you are replacing damaged outside trim, the 77-3454 is the part; the 47260707 belongs on a CO100 electronic access opening and does not accept a mechanical mortise cylinder trim in place of its keypad.
3) Can I use the Sargent 77-3454 with lever trim, or is it knob only?
Either. The escutcheon accommodates both knob and lever trim, so you can match whatever the rest of the openings in the building use without changing the plate.
4) What is the emergency release on this Sargent escutcheon for?
The 77-3454 carries an integrated emergency release, which gives authorized staff quick access from the outside in an urgent situation. That is the reason it shows up on patient rooms, restrooms and dorm-type openings rather than plain office doors.
5) What finishes does the Sargent 77-3454 escutcheon come in?
Eleven: 03 Bright Brass, 04 Satin Brass, 09 Bright Bronze, 10 Satin Bronze, 10B Dark Oxidized Satin Bronze oil rubbed, 10BL Dark Oxidized Satin Bronze clear coated, 15 Satin Nickel, 26 Bright Chrome, 26D Satin Chrome, 32 Bright Stainless, 32D Satin Stainless. For a repair on an existing door, match the BHMA number stamped on the lock you are replacing rather than eyeballing the color, since 10B and 10BL look close but differ in coating.
6) I need an escutcheon in an aged bronze tone for exit device trim, not a mortise lock - what should I look at instead of the Sargent 77-3454?
The Sargent 77-3454 is made for 8200 Series mortise lock trim, so it will not land on an exit device. For exit trim, the Schlage Electronics 47260708 is a CO Series exterior escutcheon specifically for exit trim in an aged bronze finish, with a keypad function. Keep in mind that is an electronic CO-100 component, so it fits an access-control opening rather than a mechanical one. The 77-3454 covers the mechanical mortise side and is offered in eleven finishes including 10B dark oxidized satin bronze oil rubbed and 10 satin bronze clear coated if bronze tone is what you are matching.
7) Is this a genuine Sargent part or an aftermarket copy?
Genuine Sargent. The 77-3454 is an authentic OEM replacement part for the 8200 Series, which matters if the opening has to keep its original hardware assembly intact.
8) Is the Sargent 77-3454 suitable for residential doors?
It is built as commercial hardware and belongs on commercial openings, offices, schools, healthcare, retail, government and multi-tenant residential buildings. For a single-family house it is more lock than the door needs.
9) We are standardizing stainless trim across a facility - does the Sargent 77-3454 come in stainless, or do I need a different brand?
The Sargent 77-3454 is offered in 32 bright stainless steel and 32D satin stainless steel, along with 26 bright chromium and 26D satin chromium plated over nickel if you are matching an existing chrome-tone set. Among the comparable escutcheons, the MS Sedco ESC is also a stainless plate, but it is a decorative trim for R4 and R6 round switches rather than lock trim, so it will not serve a mortise opening.
