Sargent 77-3454 20D – Frequently Asked Questions

1) Does the 77-3454 escutcheon work with LW1 or KW1 keyways?
Both. The 77-3454 uses the LW1/KW1 design, so it suits cylinders in either of those common commercial keyways. That matters if you are keying into an existing building master system and need the outside plate to accept the cylinder you already carry.
2) What does the emergency release on the Sargent 77-3454 do?
The plate carries an integrated emergency release, the feature used on privacy-type openings so staff can override the inside lock from the corridor side. It is the reason this escutcheon is specified in healthcare and institutional restrooms and patient rooms rather than a plain keyed plate. If your existing 8200 trim has that small release hole above or below the knob, this is the matching part.
3) Is the 77-3454 the outside plate or the inside plate?
Outside only. The 77-3454 is the exterior, or keyed, side escutcheon of the 8200 Series trim set. If the damaged plate is on the room side you need the matching inside escutcheon instead, and if both sides are worn you will need both parts to make the opening look consistent.
4) Can I use this escutcheon with a knob instead of a lever?
Either one. The 77-3454 plate is built to take both knob and lever trim configurations on the outside of an 8200 Series mortise lock, so the same part covers both. If your building is standardizing on levers for accessibility reasons, you can change the trim style without changing the escutcheon.
5) What finish is the Sargent 77-3454 escutcheon, and will it match my other 8200 trim?
Dark Bronze Painted, Sargent's 20D (also cited as 690 dark bronze). It is a painted finish, not plated oil-rubbed bronze, so it matches other 20D/690 Sargent trim on the same opening. If the rest of your doors are 26D satin chrome or 10B, this plate will read noticeably different.
6) I have an electronic keypad lock, not a mechanical mortise lock. Is this the right escutcheon?
No. The Sargent 77-3454 is a mechanical mortise lock part with a keyed cylinder opening and an emergency release, nothing electronic. For a keypad access control opening, the Schlage Electronics 47260707 CO Series exterior escutcheon covers cylindrical and mortise CO100 locks and ships with fasteners and O-ring, and the 47260708 is the CO-100 exit trim version in aged bronze.
7) What exact Sargent part number should I order for the dark bronze outside escutcheon?
Order Sargent model 77-3454 20D. The 77-3454 identifies the outside escutcheon for the 8200 Series with LW1/KW1 design and emergency release; the 20D suffix is the dark bronze painted finish.
8) We are moving a door from a keyed mortise lock to keypad entry - what escutcheon do we use instead of the Sargent 77-3454?
The Sargent 77-3454 is a mechanical replacement escutcheon for the Sargent 8200 Series mortise lock and is built around an LW1/KW1 keyway with knob or lever trim, so it has no provision for a keypad. For an electronic keypad opening, Schlage Electronics offers the 47260707 CO Series exterior escutcheon for CO100 cylindrical and mortise locks, supplied with fasteners and O-ring, and the 47260708 CO Series exterior escutcheon for exit trim on CO-100 in an Aged Bronze finish. Which of those two applies depends on whether the door carries a mortise or cylindrical lock body or exit device trim.
9) Is an MS Sedco ESC escutcheon plate an alternative for a mortise lock escutcheon?
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 77-3454 is an outside escutcheon for the Sargent 8200 Series mortise lock, carrying the LW1/KW1 keyway, knob or lever trim and an emergency release. If the part being replaced is on a lock body, the MS Sedco plate does not apply.
10) Is this Sargent escutcheon rated for commercial traffic or is it a residential part?
It is a commercial part, built to the 8200 Series standard for high-traffic openings, and it is specified into office buildings, schools, hospitals, government buildings, retail, multi-tenant residential and industrial facilities. For a house door with a residential-grade lockset, this is the wrong family of hardware.
11) Can I use the 77-3454 as a cover plate over a push switch or filler?
No, it is shaped and drilled for 8200 Series mortise lock trim, so it will not serve as a generic cover. For a decorative plate around a round push switch, the MS Sedco ESC stainless escutcheon plate is made for R4 and R6 round switches.
