Sargent 77-3429 32D – Frequently Asked Questions

1) What exactly is the Sargent 77-3429, and what part of the lock does it cover?
It's the inside (interior side) escutcheon plate for Sargent LW1/KW1 knob/lever and cylinder assemblies, model 77-3429. It's the plate itself, not the lock, not the knob, and not the cylinder. It mounts on the room side of the door and houses the knob or lever hub and the cylinder opening. If you need the operating hardware too, order the knob/lever and cylinder separately.
2) Will the 77-3429 escutcheon fit my Sargent lock, or do I need to check the trim designation first?
Check the trim designation. The 77-3429 is cut for LW1/KW1 knob/lever and cylinder trim, so it drops onto a Sargent assembly already using that configuration. If the door is running a different Sargent escutcheon trim, or a knob-only trim with no cylinder opening, this plate won't line up with the prep.
3) Can a Schlage CO Series exterior escutcheon be used in place of the Sargent 77-3429?
No. The Sargent 77-3429 is a mechanical inside escutcheon for LW1/KW1 knob/lever and cylinder assemblies, so it mounts on the interior face of the door and carries no electronics. The Schlage Electronics 47260707 is an exterior escutcheon for CO100 cylindrical and mortise locks with an integral keypad, supplied with fasteners and an O-ring. If the opening has a Sargent mechanical lock, the keypad escutcheon is a different product line entirely; if the opening has a CO Series access control lock, the 77-3429 will not interface with it.
4) I need a replacement escutcheon for an exit device trim, not a knob lock. Is the Sargent 77-3429 the right part?
No. The 77-3429 is built for LW1/KW1 knob/lever and cylinder configurations on a mechanical lock, covering the inside face of the door. For exit trim, the Schlage Electronics 47260708 is a CO Series exterior escutcheon made specifically for exit trim on CO-100 keypad locks, supplied in Aged Bronze. Confirm which device is on the door before ordering, because the two parts mount to different chassis types.
5) What finishes does the Sargent 77-3429 inside escutcheon come in?
Eleven finishes: 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, 20D dark statuary bronze lacquered, 26 bright chromium over nickel, 32 bright stainless, and 32D satin stainless. For a property manager matching existing openings, 26D-style satin stainless is covered by 32D and polished chrome by 26.
6) Is this a genuine Sargent part or an aftermarket copy?
Genuine Sargent. The 77-3429 is an authentic Sargent lock component built to the manufacturer's own specifications, which is why it drops into existing Sargent LW1/KW1 trim without modifying the door prep.
7) I only need to replace a damaged interior plate, not the whole Sargent lockset. Is that what this is?
Yes, that's exactly the use case. The 77-3429 is sold as a replacement part so you can restore the inside face of a Sargent LW1/KW1 opening without pulling and replacing the entire lock. Reuse the existing knob or lever and cylinder, swap the plate, and the keying is untouched.
8) Does the 77-3429 go on the inside or the outside of the door?
Inside only. It's the interior-side plate. If you're refinishing or repairing both faces of the opening, you'll need the matching outside escutcheon for that Sargent trim as a separate item, ordered in the same finish so the two faces match.
9) Will the MS Sedco ESC escutcheon plate work as a cover for a Sargent LW1 lock?
No. The MS Sedco ESC is a decorative stainless escutcheon plate made for R4 and R6 round push switches, part of a switch line rather than a lock line. The Sargent 77-3429 is a commercial mechanical lock replacement part that houses and protects the knob/lever and cylinder interface on the inside of the door, and it is offered in 11 finishes including 03 Bright Brass Clear Coated and 32D Satin Stainless Steel. The two parts serve different openings in the door and are not interchangeable.
10) Is the Sargent 77-3429 escutcheon rated for commercial traffic, or is it a residential part?
It's a commercial part. Sargent lists the 77-3429 as commercial mechanical lock trim, and it's used in office buildings, schools, healthcare, retail, government facilities, multi-tenant residential and industrial sites.
11) If I am standardizing a facility on keypad access, does the Sargent 77-3429 still have a role?
It depends on which doors you convert. The 77-3429 is a commercial replacement escutcheon for Sargent mechanical lock assemblies using LW1/KW1 knob/lever and cylinder trim, so it stays relevant on the mechanical openings you keep. On doors moving to CO Series keypad hardware, the exterior escutcheon is the keypad unit itself, such as the Schlage Electronics 47260707 for cylindrical and mortise locks or the 47260708 for exit trim. Many facilities run both and stock the mechanical escutcheon in the finish that matches the rest of the openings.
