Sargent 10-3428 – Frequently Asked Questions

1) Will the Sargent 10-3428 tailpiece work on a non-Sargent cylinder?
No. The 10-3428 is a Sargent-specific part made to fit Sargent mechanical lock cylinder assemblies. Tailpiece length and drive geometry vary by manufacturer, so a Corbin Russwin or Schlage cylinder needs its own tailpiece. If you are replacing a knob or lever cylinder in Sargent hardware with an aftermarket unit, the Kaba Ilco 1579 is a knob and lever cylinder built for Sargent.
2) The Sargent 10-3428 tailpiece pack only replaces the tailpiece. What should I order if the whole knob or lever cylinder needs to be replaced instead?
The Sargent 10-3428 is a tailpiece pack, a replacement part for Sargent mechanical lock cylinders, so it restores the drive component rather than the cylinder body. When the cylinder itself is worn or must be rekeyed out of the existing system, the Kaba Ilco 1579 is a knob and lever cylinder built for Sargent applications, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. Those supply the complete plug and housing; the 10-3428 does not.
3) What does the SF option mean on the Sargent 10-3428 tailpiece pack?
SF is the configuration designation the pack is supplied under, and it identifies which Sargent cylinder applications the tailpiece is cut for. Order the option that matches the hardware you are servicing, since tailpiece packs are not interchangeable across options.
4) My Sargent lock turns the key but the bolt does not move. Is a tailpiece the fix?
That symptom points at the drive between the cylinder and the lock body, which is exactly what the tailpiece does. If the cylinder plug rotates freely with the correct key but nothing retracts, a worn, bent, or wrong-length tailpiece is the usual cause and the 10-3428 pack replaces it without pulling the whole cylinder out of service.
5) If I am replacing a whole rim cylinder rather than just a tailpiece, what should I be looking at?
For a full rim cylinder swap, the tailpiece cam orientation is the deciding spec. Schlage's 20-021 rim cylinder uses a vertical tailpiece cam and the 20-022 uses a horizontal one, while the 20-057 is a full size interchangeable core rim cylinder with a convertible cam. Corbin Russwin's 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Match the cam orientation your exit device or rim lock requires.
6) Is a Schlage 20-021 or 20-022 rim cylinder an equivalent to the Sargent 10-3428?
No. The Sargent 10-3428 is a tailpiece pack supplied as a service component for Sargent cylinder assemblies. The Schlage 20-021 and 20-022 are complete 6-pin rim cylinders supplied with two keys, the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam. Those are whole cylinders with the tailpiece orientation already determined, not a loose tailpiece kit for an installed Sargent cylinder.
7) We want to move a Sargent opening onto interchangeable core instead of servicing the existing cylinder. What are the options?
The Sargent 10-3428 tailpiece pack keeps an existing Sargent mechanical lock cylinder in service rather than changing the keying platform. To convert to interchangeable core, BEST offers the 1CB 150 Series interchangeable core cylinder and the 1CDF drill resistant patented 7-pin brass 150 Series core; on the Schlage side the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those change the core format at the opening, which the 10-3428 does not.
8) The Sargent cylinder is in a mortise lock body and needs replacing outright. What mortise cylinders can I use?
The Sargent 10-3428 is a tailpiece pack for Sargent cylinder service and is not a mortise cylinder. For a mortise housing replacement, the Corbin Russwin 1000 Grade 1 Series is a 1-1/2 inch mortise cylinder with an A02 straight cam, the 1070 Grade 1 Series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway. Confirm the cam style your Sargent lock body requires before ordering.
9) Our exit device needs a rim cylinder with a specific tailpiece length. Does the Sargent 10-3428 cover that?
The Sargent 10-3428 is a tailpiece pack sold as a Sargent cylinder replacement component for commercial mechanical lock systems, not a rim cylinder assembly. If the exit device needs a rim housing with a defined tailpiece, the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, and the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam. Those ship as the complete rim unit.
10) Will the Sargent 10-3428 work on a deadbolt or an aluminum storefront deadlock?
The Sargent 10-3428 tailpiece pack is engineered for compatible Sargent mechanical lock cylinder assemblies, so it is tied to Sargent hardware rather than to a general deadbolt or storefront application. For a key-in-deadbolt cylinder, the Kaba Ilco 1549 Series is built for that function. For aluminum storefront, the Adams Rite 4036 is a Grade 1 mortise cylinder in the 4036 Series, and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock.
11) Is the Sargent 10-3428 tailpiece pack suitable for commercial and institutional buildings?
Yes, it is a commercial-duty part. Sargent lock parts like this are used in office buildings, schools, hospitals, government facilities, warehouses, retail, and multi-tenant residential where Sargent mechanical locks are already standardized across the openings.
12) Does buying the Sargent 10-3428 tailpiece pack change my keying?
No. The tailpiece carries no pins and no keyway, so it has no effect on how the cylinder is keyed. Your existing keys and any master keying in the building stay as they are.
13) Is there a universal cylinder that avoids having to match Sargent-specific parts like the 10-3428?
The Sargent 10-3428 is specified with the SF Option and made to Sargent tolerances, so it is matched to the Sargent assembly it serves. If you would rather stock one cylinder across mixed key-in-knob and lever openings, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder. It covers multiple lock brands from a single part number instead of a brand-specific service component.
