Sargent 28-11G05-LJ-26D-LC – Frequently Asked Questions

1) Does the Sargent 11G05 come with a cylinder, or do I have to supply one?
No cylinder is included. The 11G05-LC is a less-cylinder lockset, so you order the cylinder separately. It accepts Sargent key systems including Degree and Signature, plus SFIC and Schlage and Medeco LFIC cylinders, so it can be brought onto an existing keyway rather than forcing a new one. It is a single cylinder, keyed function.
2) What does Entrance/Office function mean on the 11G05, and is it the right lock for an office door?
Entrance/Office (F109) means the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. It suits office and tenant entry doors where staff want to leave the door unlocked during business hours and key it locked at the end of the day. If you need a door that stays locked at all times and only opens by key from outside, that is a storeroom function instead, such as the Cal-Royal AG05.
3) Will the 11G05 latch into the strike already in my frame?
The 11 Line ships with an ANSI 4-7/8 inch strike with a 1-1/4 inch lip and a 1/2 inch latchbolt throw. If your frame is already prepped for a standard ANSI 4-7/8 inch strike, which is the normal commercial hollow metal prep, it goes straight in. Frames cut for a small T-strike or a residential round-corner strike will need the opening enlarged.
4) Can the Sargent 11G05 go on a 90-minute fire-rated stairwell or corridor door?
Yes. The T-Zone 11 Line is UL-cUL fire rated up to 3 hours and NFPA 80 compliant, so it covers the usual 20, 45, 60 and 90 minute openings. It is also ADA compliant, which the lever trim supports for accessible openings.
5) What is a lighter-duty entrance/office lever if Grade 1 is more than the opening needs?
The Sargent 11G05-LC is a Grade 1 entrance/office cylindrical leverset. If the opening does not need Grade 1, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever lock with the same entrance/office function, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors. The Sargent covers 1-3/4 inch to 2-1/2 inch doors on a 2-3/4 inch backset, so on thicker doors the Grade 1 body is the one that fits.
6) What should I use instead of the Sargent 11G05 on a door that needs storeroom function?
The Sargent 11G05-LC is keyed entrance/office, where the lever can be left unlocked. For a door that must stay latched and locked at all times, the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors.
7) Do I need to order the 11G05 handed, left or right?
No. The 11G05 is non-handed, so one lock covers either swing and you do not have to stock both hands across a building. Pick the lever style (J or L) and rose, and the same body works on every opening.
8) Is the Sargent 11G05 durable enough for a high-traffic entrance, and how does it compare to Grade 2 entry levers?
It is ANSI/BHMA A156.2 Series 4000 Grade 1, heavy duty, with UL Above and Beyond cycle testing completed at 7.6 million cycles (Verification ID V584148). The T-Zone body resists torque and needs no through bolts or surface screws. A Grade 2 entrance/office lever like the Falcon B511CP6D is medium duty and a lighter-traffic choice; Grade 3 options such as the Cal-Royal AUS00 are lighter still.
9) Can I change the 11G05 to a different function later without buying a whole new lock?
Yes. The 11 Line uses a modular, field-changeable design, so one lockbody supports multiple functions and the function can be swapped in the field. For a maintenance shop that means fewer whole locksets on the shelf when a room changes use.
10) What Grade 1 cylindrical lever alternatives are there if I am not on a Sargent keyway?
For Grade 1 cylindrical lever locks from other lines, the Corbin Russwin CL3300 and CL3100 Series cover 1-3/4 inch to 2 inch doors, and the Dexter C1000 Series Grade 1 locks cover 1-3/8 inch to 2 inch depending on function. Falcon's K Series K101 is Grade 1 heavy duty and fire rated for 1-3/8 inch to 2-1/4 inch doors. None of those match the Sargent 11 Line's 1-3/4 inch to 2-1/2 inch thickness span, so on a thick door the Sargent is the one that fits.
11) I need a keyed entry lever but the opening has no cylinder prep concerns, just a wide stile aluminum door with a deep backset. Does the 11G05 handle that?
Backset range on the 11 Line runs from the standard 2-3/4 inch out to 5 inch, so deep-stile openings are covered. Specify the backset with the order, since the standard supplied backset is 2-3/4 inch.
12) What non-keyed Grade 1 lever matches the Sargent 11G05 on adjacent doors that do not need a cylinder?
The Sargent 11G05-LC is a keyed single cylinder entrance/office lock supplied less cylinder. For corridor or closet doors in the same run that need no key, Grade 1 non-keyed options include the Falcon K101 passage cylindrical lock with non-handed levers, fire rated, for 1-3/8 inch to 2-1/4 inch doors; the Falcon T101 heavy duty passage lever; the Corbin Russwin CL3110 Grade 1 vandal resistant passage/closet lever for 1-3/4 inch to 2 inch doors; and the Design Hardware X75 Grade 1 passage lever for 1-3/4 inch doors.
13) Is a dummy lever a substitute for the Sargent 11G05 on an inactive leaf?
No. The Sargent 11G05-LC is a keyed cylindrical lock with a working latchbolt and a 4-7/8 inch ANSI strike with 1-1/4 inch lip. A dummy trim has no latch and no strike prep at all. For the inactive leaf, the BEST 9K series 1DT single dummy trim is Grade 1 heavy duty non-keyed, the BEST 7KC series 1DT is the Grade 2 medium duty equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever.
14) What is the difference between the Sargent 11G05 and the Hager 2525 entry lock?
Both are keyed cylindrical lever locks for commercial entry use. The Sargent 11G05-LC is ANSI/BHMA Grade 1 heavy duty with a 2-3/4 inch backset, non-handed, for doors 1-3/4 inch to 2-1/2 inch thick, and ships less cylinder so you supply the Sargent, SFIC, Schlage or Medeco LFIC cylinder. The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle for doors 1-3/8 inch to 2 inch thick.
15) If I need an electrified lever on a controlled-access door, what replaces the Sargent 11G05?
The Sargent 11G05-LC is a mechanical keyed entrance/office lock with no electrical option. For access control, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock operating at 12VAC/DC for doors 1-3/4 inch to 2 inch thick, available with an NZ lever and D rose.
16) Can I use a keypad lever instead of the Sargent 11G05 to avoid issuing keys?
The Sargent 11G05-LC is a key-operated entrance/office lock supplied less cylinder, so every user needs a key. Codeless alternatives include the Lockey 1150 heavy duty mechanical keypad lever set with double combination in passage function for doors 1-1/8 inch to 2 inch thick, and the Delaney LP250 Grade 2 electronic keypad leverlock. Note the Sargent keys into existing Sargent Degree and Signature, SFIC, Schlage and Medeco LFIC systems, which a keypad lever will not do.
17) I want knobs instead of levers on an entrance door - what is the closest option to the Sargent 11G05?
The Sargent 11G05-LC is a lever-handle lock and is ADA compliant per its published certifications. If a knob is required, the Arrow HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for doors 1-3/8 inch to 1-3/4 inch thick. Confirm knob trim is acceptable for your jurisdiction before substituting, since the Sargent lever is the ADA-compliant form.
18) What do I use on a utility or patient room door where entrance/office function is wrong?
The Sargent 11G05-LC is entrance/office, which lets the lever be left in an unlocked state. For institutional doors that need key operation from both sides with no inside unlocking, the Dexter C1000 series offers a Grade 1 asylum F87 lock for doors 1-3/8 inch to 2 inch thick, and the Arrow MK33-BD-CS is an asylum/institution/utility cylindrical lock with a ball knob and a conventional Schlage C keyway cylinder.
19) What lever and rose choices are there on the Sargent 11 Line 11G05?
Two lever designs, J Lever and L Lever, both with the L rose at 3-1/8 inch, in 26D satin chromium plated over nickel. If you are matching existing Sargent trim on other doors in the building, the lever letter is what you match on.
20) Is there an antimicrobial option for healthcare openings on the Sargent 11 Line?
Microshield coating is offered as an option on the T-Zone 11 Line for high-touch applications, meant to supplement cleaning protocols rather than replace them. The lockset is also built with 68 percent post-consumer recycled content, which counts toward LEED MR credit 4 if you are documenting a project.
21) Are the Baldwin Estate 5103 or Emtek leversets alternatives to the Sargent 11G05?
They serve different openings. The Sargent 11G05-LC is a commercial Grade 1 heavy duty keyed cylindrical lock built for office buildings, schools and healthcare. The Baldwin Estate 5103 is offered in passage, privacy and half dummy functions with the 5048 rose, and the Emtek Classic and Arts and Crafts leversets are dummy pairs - none of these carry a keyed entrance/office function, so they suit residential and decorative interior doors rather than a keyed commercial entrance.
