Sargent 81-0646 26D – Frequently Asked Questions

1) I need a keyed or thumbturn plate on the inside, not a blank one. Is this the right part?
No. The 81-0646 is blank, with no keyway and no thumbturn cutout, so it suits passage or single-sided access where the interior needs trim only. If the inside face has to take a cylinder or a thumbturn, you need the prepped escutcheon for that function in the WT(78/82) series, not this one.
2) Will the 81-0646 escutcheon fit a Sargent lock other than the 78 or 82 series?
No. The 81-0646 is built for the Sargent WT(78/82) lock series and is specified for proper fit and alignment with that hardware. If your lockset is a different Sargent series, order the escutcheon called out for that series instead.
3) Do I need to redrill or modify the door to install this Sargent escutcheon?
No door prep changes. The 81-0646 is a drop-in replacement that installs to the existing door preparation on a WT(78/82) lockset, so it is a straight swap for a damaged or mismatched inside plate.
4) Is the Schlage Electronics 47260707 CO Series exterior escutcheon an alternative to the Sargent 81-0646 blank inside escutcheon?
No. The Sargent 81-0646 is a blank inside escutcheon - an interior trim plate with no keyway or thumbturn, made as a replacement part for the WT(78/82) Sargent mechanical lock series. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks on the CO100, and it is a keypad unit supplied with fasteners and an O-ring. One is inside blank trim for a mechanical lockset, the other is an outside keypad housing for an electronic lock, so they do not interchange.
5) I manage a building with a mix of brass finishes on the doors. Which 81-0646 finish matches polished brass trim?
For polished brass trim, order finish 03, bright brass clear coated. If the existing plates are a brushed or satin brass, 04 satin brass clear coated is the match. Both are offered on the 81-0646, so you can standardize the inside plates across openings without changing the rest of the lockset.
6) Is there an equivalent escutcheon from another brand I can use instead of the Sargent 81-0646?
Not as a direct substitute. The escutcheons stocked from other brands serve different hardware entirely: the Schlage Electronics 47260707 is a CO Series keypad exterior escutcheon for cylindrical and mortise locks, the 47260708 is a keypad escutcheon for exit trim, and the MS Sedco ESC is a decorative stainless plate for R4 and R6 round switches. None of those are a blank mechanical-lock inside plate for a Sargent WT(78/82). For that lockset, stay with the Sargent part.
7) Our building standard is oil rubbed bronze, and the Schlage CO escutcheon only came up in aged bronze - what matches on the Sargent side?
The Sargent 81-0646 blank inside escutcheon is produced in twelve finishes, including 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 10 satin bronze clear coated, 20D dark statuary bronze lacquered, and 09 bright bronze clear coated, alongside brass, chrome, nickel and stainless options. The Schlage Electronics 47260708 CO Series exterior escutcheon for exit trim is an aged bronze finish part. For a Sargent WT(78/82) lockset held to a dark bronze standard, 10B or 10BL is the closer match.
8) I need an escutcheon for exit device trim, not a mortise lockset - will the Sargent 81-0646 work?
The Sargent 81-0646 is built for the Sargent WT(78/82) mechanical lock series and mounts as a blank inside plate on that lockset. For exit trim, the Schlage Electronics 47260708 is a CO Series exterior escutcheon made specifically for exit trim on the CO-100 and comes in an aged bronze finish. Confirm which device is on the door before ordering, since the two are prepped for different hardware.
9) We searched escutcheon plates and got the MS Sedco ESC - is that the same kind of part as the Sargent 81-0646?
They are unrelated. 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-plate style actuator rather than a lock. The Sargent 81-0646 is commercial door hardware, a blank inside escutcheon replacement part for the WT(78/82) mechanical lock series. If the door has a Sargent lockset, the 81-0646 is the plate to specify.
10) Is the Sargent 81-0646 rated for commercial traffic, or is it a residential part?
Commercial. The 81-0646 is built to Sargent's commercial hardware specifications and goes into offices, schools, hospitals, retail, government buildings, multi-tenant residential, and industrial facilities. It is not a light-duty residential trim plate.
11) Is the 81-0646 a genuine Sargent part or an aftermarket copy?
Genuine Sargent. It is an authentic Sargent replacement component catalogued under model 81-0646, made to the same specifications as the original trim on the WT(78/82) lockset, which is what keeps the fit and the finish consistent with the rest of the hardware.
