Sargent 28-11G54 LB 10 – Frequently Asked Questions

1) How does the dormitory function on the Sargent 11G54 actually work on a door?
The 11G54 is the corridor/dormitory function in Sargent's 11 Line. It is a single cylinder lock, so the key works the outside only and the inside lever always retracts the latch for free egress. That is the function you want on a dorm room or apartment corridor door where the occupant locks up behind them and nobody gets trapped inside.
2) Can I drop the Sargent 11G54 into an existing 161 door prep?
Yes, it fits standard 161 cylindrical prep with a 2-3/4 inch backset, so a door already bored for a commercial cylindrical lock takes it without new machining. T-Zone construction also means no through bolts or surface screws on the face of the door.
3) Can the Sargent 11G54 go on a fire rated door?
Yes. The 11 Line cylindrical lock is UL-cUL fire rated up to 3 hours and NFPA 80 compliant, so it can be used on rated corridor and stair openings up to that rating.
4) Can I key the Sargent 11G54 into an existing Schlage or SFIC master key system?
The 11G54 accepts SARGENT Degree and Signature, SFIC, Schlage and Medeco LFIC cylinders, so it can be brought into most existing systems. On the order you pick a 6 pin standard cylinder, 60 Sargent large format interchangeable core, or 70 Sargent small format interchangeable core, then choose keyed different, keyed alike, master keyed, or standard keying, plus the keyway (LA is standard, with 40 other Sargent keyways available).
5) My door is only 1-3/8 inches thick. What should I use instead of the Sargent 11G54?
The Sargent 11 Line starts at 1-3/4 inches, so a 1-3/8 inch leaf is out of range. Look at the Falcon K101, a Grade 1 lock rated 1-3/8 to 2-1/4 inches, or the Dexter C1000 Series which covers 1-3/8 to 1-3/4 inches in Grade 1 classroom, classroom security and passage functions. Hager's 2525 entry and 2580 storeroom locks are Grade 2 and take 1-3/8 to 2 inch doors if Grade 1 is not required.
6) What Grade 1 cylindrical lever lock should I use for a classroom door instead of a dormitory function?
The Sargent 11G54 is a Corridor/Dormitory function lock, so it is not the right choice where a classroom function is specified. For a classroom opening, the Dexter C1000 Series classroom cylindrical lever lock is a Grade 1 keyed classroom function with a clutching lever and a 1-3/8 inch to 1-3/4 inch door thickness range. Where the spec calls for classroom security, the Dexter C1000 classroom security version is also Grade 1.
7) I need a matching non-keyed passage lever for the closet doors on the same corridor as my Sargent 11G54 locks. What are my Grade 1 options?
The 11G54 is a keyed single cylinder lock, so a closet or passage opening needs a different function. Grade 1 non-keyed passage cylindrical levers include the Falcon K101, heavy duty with a 1-3/8 inch to 2-1/4 inch door thickness range and fire rated; the Falcon T101, heavy duty with pressure release technology; the Corbin Russwin CL3110 passage/closet, vandal resistant and fire rated for 1-3/4 inch to 2 inch doors; the Dexter C1000 passage with clutching levers; and the Design Hardware X75 flat lever passage for 1-3/4 inch doors.
8) Is a Grade 2 storeroom lever like the Cal-Royal AG05 or Hager 2580 a substitute for the Sargent 11G54?
No. The Sargent 11G54 is a Grade 1 Corridor/Dormitory function lock. The Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom lever with a Withnell lever for 1-3/8 inch to 2 inch doors. Storeroom function keeps the outside lever locked at all times, while dormitory function allows the inside to lock out the corridor side. They also sit at a different ANSI grade than the 11G54.
9) Can I use the Sargent 11G54 on a patient or institutional door that calls for asylum function?
No. The Sargent 11G54 is a single cylinder Corridor/Dormitory function lock. An asylum or institution function is keyed on both sides; comparable options are the Dexter C1000 Series asylum F87 Grade 1 lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS asylum lock with ball knob and conventional Schlage C keyway cylinder.
10) My door is 2-1/4 inches thick and the lock I was quoted tops out at 2 inches. What Grade 1 lever covers it?
The Sargent 11G54 accommodates door thickness from 1-3/4 inches to 2-1/2 inches, which covers a 2-1/4 inch leaf, and it fits standard 161 prep with a 2-3/4 inch backset. Among the comparables, the Falcon K101 Grade 1 passage covers 1-3/8 inches to 2-1/4 inches, while the Corbin Russwin CL3110 Grade 1 passage is rated 1-3/4 inches to 2 inches.
11) Do I need to specify handing when ordering the Sargent 11G54?
No. The 11 Line dormitory lock is non-handed, so one part number works on left or right hand doors and you do not need to stock both. That keeps a property manager's spare count down across a building.
12) Is the Sargent 11G54 heavy duty enough for a high traffic dorm or student housing corridor?
It is ANSI/BHMA A156.2 Series 4000 Grade 1 and rated heavy duty, and Sargent ran the UL Cycle Above and Beyond test to 7.6 million cycles (Verification ID V584148). The T-Zone body is torque resistant to stop the lock twisting when someone hangs on the lever. That is the top commercial durability tier for a bored lock.
13) What lever styles, roses and finishes can I get on the Sargent 11 Line dormitory lock?
Levers come in B, J, L and P designs. Rose options are B at 2-3/4 inches, O at 2-3/4 inches, L at 3-1/8 inches and E at 3-1/2 inches, so if you are covering up an old rose footprint the larger E rose hides the most. Fourteen finishes are offered, from 26D satin chrome and 10B oil rubbed bronze through to black and white suede powder coat.
14) Is the Sargent 11G54 lever ADA compliant for a healthcare or school corridor?
Yes, it is a lever handle lockset listed as ADA compliant, which is what you need where knobs are not acceptable on accessible routes. It also carries ANSI/BHMA A156.2 Series 4000 Grade 1 and several ASTM certifications.
15) What other Grade 1 cylindrical levers could I use instead of the Sargent 11G54?
If the opening does not need a keyed dormitory function, the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever for 1-3/4 to 2 inch doors, and the Falcon K101 is a Grade 1 fire rated passage lock covering 1-3/8 to 2-1/4 inch doors, which reaches thinner leaves than the Sargent. For keyed Grade 1 classroom or asylum functions, the Dexter C1000 Series covers those, though it is rated for 1-3/8 to 1-3/4 inch doors only.
16) My spec calls for an electrified cylindrical lever instead of a mechanical dormitory lock. What matches?
The Sargent 11G54 is a mechanical cylindrical lock with a keyed single cylinder. Where access control is required, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever at 12VAC/DC for 1-3/4 inch to 2 inch doors, available with an NZ lever and D rose. For standalone keypad access, the Delaney LP250 is a Grade 2 electronic keypad leverlock.
17) What is the difference between the Sargent 11G54 dormitory lock and a Grade 2 entrance/office lever?
The Sargent 11G54 is a Grade 1 heavy duty keyed Corridor/Dormitory cylindrical lever. Grade 2 entrance/office alternatives include the Falcon B511CP6D, a medium duty entry/office cylindrical lever, and the Hager 2525 commercial entry lock for 1-3/8 inch to 2 inch doors. Entrance/office function is typically locked and unlocked by a button or thumbturn for day use, where the dormitory function on the 11G54 is intended for corridor doors in multi-occupant buildings.
18) I need a lever on an inactive leaf to match my Sargent 11G54 openings. What dummy trim options are there?
The 11G54 is a keyed working lock, not dummy trim. For an inactive leaf, Grade 1 dummy options include the BEST 9K Series 1DT single dummy trim cylindrical lever, non-keyed and heavy duty, and the Accentra 455LN Augusta heavy duty single dummy cylindrical lever. A Grade 2 alternative is the BEST 7KC Series single dummy trim, medium duty.
19) For a residential-style bedroom or bath door in the same building as my Sargent 11G54 locks, what privacy lever should I order?
The 11G54 is a keyed commercial Grade 1 lock and is not a privacy set. For a bed or bath door, privacy options include the Hager 2540 Grade 2 privacy cylindrical lock with Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA privacy lock with Tudor knob, non-keyed and fire rated, the Kwikset 300BRNL Breton privacy lever for 1-3/8 to 1-3/4 inch doors, and the Baldwin Estate 5103 privacy lever with 5048 rose for decorative openings.
20) Does the Corbin Russwin CL3300 lock lever work as replacement trim for a Sargent 11G54?
No. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, rated for 1-3/4 inch to 2 inch doors. It is trim for those Corbin Russwin platforms, not for the Sargent 11 Line. Replacement levers for the 11G54 come from the Sargent 11 Line lever offering, which includes the B, J, L and P levers.
21) What should I use instead of the Sargent 11G54 on a light-duty interior residential door?
The Sargent 11G54 is a Grade 1 heavy duty commercial cylindrical lock built for high-traffic openings. On a light-duty interior door, Grade 3 and Grade 2 leversets cover the need: the Callan Asheville Grade 3 passage leverset in satin nickel, the Kwikset 200BRNL Breton Grade 3 passage lever for 1-3/8 to 1-3/4 inch doors, the Bravura Miramar Grade 2 passage leverset with round trim in US4 satin brass, and the Arrow GL01 Grade 2 passage lock with Sierra lever for 1-3/4 to 2 inch doors.
22) If I need a different function later, do I have to replace the whole Sargent 11 Line lock?
No. The 11 Line uses a modular design that allows field function changes, so a dormitory lock can be reconfigured rather than scrapped when a room changes use. Sargent publishes an 11 Line all-functions installation instruction sheet and a parts manual for the series.
23) Does the Sargent 11G54 help on a LEED project?
It is made from 68% post-consumer recycled content, which counts toward LEED MR credit 4. An optional Microshield antimicrobial coating is also available, which is often specified alongside it in healthcare work.
