Sargent 28-11G04-LL-26D-LC – Frequently Asked Questions

1) Does the Sargent 11G04-LC come with a cylinder, or do I have to order one separately?
It ships less cylinder. The 11G04-LC is the keyed storeroom lock body and trim only, so you supply the cylinder. It accepts SARGENT key systems including Degree and Signature, plus SFIC and Schlage and Medeco LFIC, which is what makes it easy to bring onto an existing facility keyway. It is a single cylinder keyed function, so one cylinder per lock on the outside.
2) What does the storeroom/closet function on the Sargent 11G04 actually do?
Outside lever stays locked at all times and is retracted by key only. Inside lever always turns free for egress. There is no button or thumbturn to leave it unlocked, which is why it is the standard choice for mechanical rooms, IT closets, and supply storage where you do not want staff defeating the lock. The 11 Line is modular, so the function can be changed in the field without swapping the whole lock.
3) Does the Sargent 11G04 drop into an existing 161 door prep?
It does. The 11 Line fits standard 161 prep, which is the 2-1/8 inch cross bore used on nearly every commercial cylindrical lock, so on a retrofit you are usually reusing the existing holes. Standard backset is 2-3/4 inches, with backsets available out to 5 inches maximum for wide-stile or unusual openings. Strike is the ANSI 4-7/8 inch with a 1-1/4 inch lip.
4) Can the Sargent 11 Line go on a fire rated door?
Yes. The 11 Line carries a UL-cUL fire rating up to 3 hours and is ANSI/BHMA A156.2 Series 4000 Grade 1 certified, with ADA compliant lever trim. That combination covers most stairwell, corridor, and mechanical room openings in a rated assembly.
5) What is a Grade 2 storeroom lever alternative to the Sargent 11G04-LC?
The Sargent 11G04-LC is a Grade 1 storeroom/closet cylindrical lever lock. If a Grade 2 storeroom lever fits the opening, the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever and a 1-3/8 inch to 2 inch door thickness range. Both are storeroom function like the Sargent, but neither covers the thicker doors the 11G04-LC accepts.
6) I need a non-keyed lever on the same doors as the Sargent 11G04-LC storeroom lock - what matches?
The 11G04-LC is keyed, single cylinder, storeroom/closet function. For openings on the same run that need free passage instead, Grade 1 passage levers include the Falcon K101, which is heavy duty with a fire rating and a 1-3/8 inch to 2-1/4 inch door thickness range, the Falcon T101 heavy duty passage lever, the Dexter C1000 passage lever with clutching and a 1-3/8 inch to 1-3/4 inch range, and the Corbin Russwin CL3110 vandal resistant passage lever, fire rated, 1-3/4 inch to 2 inch. All are non-keyed, so they take no cylinder at all.
7) The 11G04-LC storeroom function always locks the outside lever - what should I use if I need a classroom lock instead?
The Sargent 11G04-LC is storeroom/closet function, so the outside lever stays locked and the key retracts the latch. Where staff need to lock and unlock the outside lever from the corridor, the Dexter C1000 classroom lever is Grade 1 with clutching and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Dexter C1000 classroom security lever is Grade 1 for keying from both sides. Cal-Royal AG03 is a classroom lever in the AG series with a 2-3/4 inch backset, matching the 2-3/4 inch backset the Sargent uses.
8) Does the Accentra 107S Schlage cylinder adapter kit let me use a Schlage cylinder in the Sargent 11G04-LC?
No. The 11G04-LC ships less cylinder and already accepts SARGENT Degree and Signature, SFIC, and Schlage and Medeco LFIC cylinders directly, so no adapter is needed to key it into a Schlage LFIC system. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, not for the Sargent 11 Line.
9) Do I need to specify handing when ordering the Sargent 11G04?
No. The lock is non-handed, so one part number covers left and right hand doors and you can stock a single SKU across a building. That also means a lock pulled off one opening can go back on another without reworking it.
10) What do I choose between when ordering the Sargent 11G04 lever and rose?
Three choices. Lever style is B or L. Rose is L at 3-1/8 inches or O at 2-3/4 inches. Finish is 26D satin chromium plated over nickel or 10BE dark oxidized satin bronze. Rose diameter is worth checking on a retrofit, since the larger 3-1/8 inch L rose will cover more of the old trim footprint than the 2-3/4 inch O.
11) Is this lock durable enough for a high traffic commercial door?
It is built for it. The T-Zone construction is torque resistant, so hanging weight on the lever does not twist the lock, and it mounts without through bolts or surface screws. Sargent has it independently tested to 7.6 million cycles (Verification ID V584148), well beyond the Grade 1 heavy duty threshold. Typical uses are schools, hospitals, offices, warehouses, and government buildings.
12) I am standardizing a building on one lock line. Can I use the 11G04 on doors that need passage or classroom function too?
Yes, and that is the argument for the 11 Line. The lock is modular, so functions change in the field with simple cylinder removal. You order the 11G04 storeroom for closets and mechanical rooms and other 11 Line functions elsewhere, and the levers, roses, finishes, and 161 prep stay the same across every opening. It also cuts the spare parts you carry.
13) What Grade 1 lever should I use on a psychiatric or utility door where the Sargent 11G04-LC storeroom function is not right?
The Sargent 11G04-LC is a Grade 1 storeroom/closet lever, keyed on one side. For asylum/institution/utility openings that need keyed operation on both sides, the Dexter C1000 asylum (F87) is Grade 1 with a 1-3/8 inch to 2 inch door thickness range. The Arrow MK33-BD-CS is an asylum function lock as well, but it is a heavy duty ball knob rather than a lever, so it will not meet the lever requirement the Sargent satisfies.
14) Can I use an entrance or office lever in place of the Sargent 11G04-LC storeroom lock?
They behave differently. The 11G04-LC is storeroom/closet function, so the outside lever is always locked with no way to leave it unlocked. Entrance/office levers such as the Falcon B511CP6D, Grade 2 medium duty, and the Cal-Royal AUS00, Grade 3 with a solid brass forged body and a 1-3/8 inch to 1-3/4 inch door thickness range, let the outside lever be left unlocked by pushbutton or turn. The Hager 2525 is a Grade 2 entrance lever with a 1-3/8 inch to 2 inch range. Use those only where an unlockable outside lever is acceptable.
15) Is there an electrified cylindrical lever comparable to the Sargent 11G04-LC for access control?
The 11G04-LC is a mechanical, keyed storeroom lever with no electrical option. Where the opening is going on an access control system, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever at 12VAC/DC with a 1-3/4 inch to 2 inch door thickness range, available with the NZ lever and D rose. That covers the same Grade 1 cylindrical footprint while adding remote release, which the Sargent does not provide.
16) Would a Kwikset or Baldwin lever work as a substitute for the Sargent 11G04-LC in a commercial building?
Not for the same duty. The 11G04-LC is a commercial, heavy duty, Grade 1 cylindrical lever tested to 7.6 million cycles and certified to ANSI/BHMA A156.2 Series 4000. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 with a 1-3/8 inch to 1-3/4 inch door thickness range, and the Baldwin Estate 5103 is offered in passage, privacy and half dummy functions. Those are residential-style trims in non-keyed or privacy functions, so they neither match the storeroom function nor the Grade 1 duty level.
17) What is the difference between the Sargent 11G04-LC and a keypad lever like the Lockey 1150 or Delaney LP250?
The 11G04-LC is keyed, single cylinder, and less cylinder, so it takes a SARGENT Degree or Signature, SFIC, or Schlage or Medeco LFIC cylinder and is operated by key. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination and a 1-1/8 inch to 2 inch door thickness range, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those open by code rather than key, so they do not tie into an existing master key system the way the Sargent does.
18) Which passage lever is closest in duty to the Sargent 11G04-LC when I want the same Grade 1 build on non-locking doors?
The Sargent 11G04-LC is Grade 1 heavy duty. Among Grade 1 passage levers, the Design Hardware X75 passage lever lockset in the X Series is Grade 1 for 1-3/4 inch doors, while the Design Hardware J75 flat lever is the Grade 2 J Series equivalent. The Accentra 5301LN Augusta and 4601LN are both Grade 2 passage levers, and the Arrow GL01 Sierra lever is Grade 2 for 1-3/4 inch to 2 inch doors. Match the X75 if you want to hold Grade 1 across the whole opening set.
19) I need a privacy lever for restrooms in the same building as the Sargent 11G04-LC storeroom locks - what should I order?
The 11G04-LC is keyed storeroom function and has no inside privacy button, so it is the wrong function for a restroom. Privacy options include the Hager 2540 with the Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA, which is a fire rated privacy lock with a Tudor knob for 1-3/4 inch to 2 inch doors, and the Baldwin Estate 5103 privacy lever. Note the Arrow is a knob rather than a lever, so it will not match an ADA lever specification.
20) Does the Sargent 11 Line count toward LEED credits?
It is made from 68 percent post-consumer recycled content, which supports LEED MR credit 4. That is the figure to put on the submittal for a project chasing recycled content points.
21) I want a matching lever on a door that needs no latch at all alongside Sargent 11G04-LC locks - what dummy trim works?
The 11G04-LC is a keyed cylindrical lever lock, so it is not the part for inactive leaf or closet-face trim. Grade 1 dummy trim options include the BEST 9K Series 1DT single dummy, heavy duty and non-keyed, and the Accentra 455LN Augusta single dummy in the 5400 Series. The BEST 7KC Series 1DT is the medium duty Grade 2 counterpart. Lever style and finish will differ from the Sargent B and L levers, so confirm appearance if the doors are in the same sightline.
