Sargent 11-2121 26D – Frequently Asked Questions

1) Will the Sargent 11-2121 latch work in a door prepped for a 2-3/4 inch backset?
No. The 11-2121 is a 5 inch backset latch assembly, built for door preps that set the lock case well back from the door edge. A 2-3/4 inch or 2-3/8 inch prep will not accept it, and the spindle and cylinder holes will not line up. If your opening is a standard 2-3/8 or 2-3/4 inch backset, you need the matching backset version of the 11-Line latch, not this one.
2) Which Sargent locksets does the 11-2121 latch assembly fit?
It is a genuine Sargent replacement part for the 11-Line lockset series, supporting the 25-Option configuration and 15-function applications. It is not a universal latch: if the lock on your door is not an 11-Line with that option and function, this assembly is the wrong part.
3) Can a Kwikset 84290 plain latch be used in place of the Sargent 11-2121 latch assembly?
No. The Sargent 11-2121 is a commercial unguarded latch assembly built with a 5 inch backset for Sargent 11-Line locksets in the 25-Option, 15-function configuration. The Kwikset 84290 is a square corner plainlatch built to a 2-3/8 inch backset, so the door bore-to-edge dimension alone rules it out of an 11-Line 5 inch backset prep, and it is not a Sargent 11-Line component.
4) Which latch should I order for a residential door with an adjustable 2-3/8 or 2-3/4 inch backset instead of the Sargent 11-2121?
The Sargent 11-2121 is a fixed 5 inch backset commercial replacement part for 11-Line locksets, so it does not fit a standard residential bore. For an adjustable 2-3/8 or 2-3/4 inch backset, the Deltana DLP23875 drive-in latch covers passage and privacy functions, and the Deltana DLE23875 drive-in latch covers entry function; both are listed for doors 1-3/8 inch to 2 inch thick.
5) What does an unguarded latch mean, and when should I not use one?
Unguarded means the latchbolt has no auxiliary deadlatching plunger beside it. That is fine on openings where the hardware spec calls for a plain latch bolt, but on an exterior or otherwise securable door where the spec calls for deadlatching, you want the guarded version instead. The 11-2121 is the unguarded variant.
6) What finishes does the Sargent 11-2121 latch come in?
Ten 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, and 26D Satin Chromium over nickel. Order the finish that matches the existing 11-Line trim on the door so the exposed faceplate does not stand out.
7) Am I ordering a complete lock or just the latch when I buy the 11-2121?
Just the latch assembly. It is a replacement part, not a lockset, so it does not include the lock case, trim, cylinder or strike. Use it to restore an existing 11-Line lock whose latch has worn or been damaged.
8) I need a fire-rated latch. Is the Sargent 11-2121 or a Kwikset RCAL latch the right call?
If the requirement is a UL 3 hour latch, the Kwikset 83521 RCAL plain latch and the Kwikset 83518 RCAL adjustable square drive latch are both described as UL 3 hour units. The Sargent 11-2121 is specified as a commercial unguarded latch assembly for Sargent 11-Line locksets at a 5 inch backset, matched by function and option code rather than by a standalone fire rating, so on a fire door the whole 11-Line lockset assembly governs what latch is correct.
9) Is the Emtek 83228 latch faceplate an equivalent to the Sargent 11-2121?
No. The Emtek 83228 is a faceplate and screws only, for a tubular pocket door privacy latch with square corners, so it replaces trim and not the latching mechanism. The Sargent 11-2121 is a complete unguarded latch assembly for Sargent 11-Line locksets with a 5 inch backset in the 25-Option, 15-function configuration, and it is offered in ten finishes including 26D satin chromium and 10B dark oxidized satin bronze.
10) Is the Sargent 11-2121 suitable for a high-traffic school or hospital door?
Yes. It is a commercial-grade part, catalogued for commercial rather than residential use, and the 11-Line is the lockset family used in offices, schools, healthcare buildings, retail, government facilities and multi-tenant housing. For fleet maintenance it lets you keep one latch part number on file across the openings running 11-Line locks at a 5 inch backset.
11) What is the difference between the Sargent 11-2121 and the Emtek LC9-DBLTCH deadbolt latch?
They serve different lock types. The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, driven electrically as part of a deadbolt. The Sargent 11-2121 is a mechanical unguarded latch assembly that services Sargent 11-Line commercial locksets at a 5 inch backset and carries no electrification.
