Sargent 28-11G13 BB 26D – Frequently Asked Questions

1) What does the Sargent 11G13 exit latch function actually do on the door?
The 11G13 is an exit-only lock: the inside lever always retracts the latch to let people out, and there is no cylinder and no outside operation. It is non-keyed, so if you need key control from the corridor side this is the wrong function. Typical uses are stairwell discharge, mechanical rooms and back-of-house doors where free egress matters and entry is controlled elsewhere.
2) Will a Sargent 11 Line cylindrical lock fit a 2 inch thick door?
Yes. The 11 Line T-Zone bored lock covers door thickness from 1-3/4 inches up to 2-1/2 inches, so a 2 inch door is in range without a thick-door kit. Standard commercial doors at 1-3/4 inches are the low end of that range.
3) Is the Sargent 11G13 fire rated for a stairwell 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. That combination covers most rated openings in stairwells, corridors and tenant separations.
4) What is a Grade 1 alternative to the Sargent 11G13 exit latch lock if the opening really needs a passage function instead?
The Sargent 11G13 is a non-keyed cylindrical lever with an exit only function, so the lever retracts the latch from one side of the opening. If the door needs to operate from both sides, Grade 1 non-keyed passage options include the Falcon K101, a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a 1-3/8 inch to 2-1/4 inch door thickness range, the Falcon T101 Grade 1 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 Dexter C1000 Grade 1 passage lever with clutching for 1-3/8 inch to 1-3/4 inch doors.
5) Will a dummy lever work in place of a Sargent 11G13?
No. The Sargent 11G13 is a cylindrical lock with an exit latch function, meaning it has a working latchbolt the lever retracts. A dummy trim has no latch at all and is pull-only. The BEST 9K Series 1DT Grade 1 heavy duty single dummy trim, the BEST 7KC Series Grade 2 single dummy trim, and the Accentra 455LN Augusta Grade 1 single dummy lever are all dummy function and would leave the door without a latching mechanism. Use one of those only on an inactive leaf or a door held closed by other means.
6) The Sargent 11G13 is non-keyed. What should I specify if the opening actually needs key control?
The Sargent 11G13 has no cylinder, so it cannot be keyed or tied into a masterkey system. For keyed cylindrical levers, 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, the Hager 2580 is a Grade 2 storeroom lever with the Withnell lever for 1-3/8 inch to 2 inch doors, the Dexter C1000 classroom is a Grade 1 keyed clutching lever for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AG03 is a classroom lever in a 6-pin Schlage C keyway with a 2-3/4 inch backset.
7) Can I use the Sargent 11G13 on a thick door, and what else fits doors over 2 inches?
The Sargent 11G13 accommodates door thickness from 1-3/4 inch to 2-1/2 inch with standard 161 preparation, which covers most thick commercial doors in a single lock. Among comparable cylindrical levers, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch, while the Corbin Russwin CL3110 and CL33903 are rated 1-3/4 inch to 2 inch and the Arrow GL01 1-3/4 inch to 2 inch. On doors thicker than those ranges, the 11G13 is the one that stays within its stated range.
8) Do I have to specify handing when ordering the Sargent 11G13?
No handing to call out. The lock is non-handed, so one part number works on left or right hand doors and you are not stuck with dead stock when a door swing changes. What you do have to choose is backset, strike, lever style, rose and finish.
9) How durable is the Sargent T-Zone lock in a high traffic building?
UL cycle testing on the T-Zone 11 Line was completed at 7.6 million cycles (verification ID V584148), which is why it gets specified on school corridors, hospital wings and high-rise stair doors. The T-Zone construction resists torque on the lever so the chassis does not twist in the door, and it mounts without through bolts or surface screws.
10) What lever, rose and finish combinations does the Sargent 11 Line come in?
Levers are B, J, L and P. Roses 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 scars from an older lock the larger E rose hides the most. Fourteen finishes run from 03 bright brass and 04 satin brass through 10B oil rubbed bronze, 26 bright chrome and 26D satin chrome, plus BSP black and WSP white suede powder coat for matching painted hardware across a property.
11) I need a keyed lock on the same doors, can the Sargent 11 Line be keyed later?
The 11G13 itself is non-keyed, but the 11 Line is modular with field-changeable functions and simple cylinder removal, so you can reconfigure rather than replace the whole lock. The line accepts SARGENT key systems including Degree and Signature, plus SFIC and Schlage and Medeco LFIC, which is what lets a facility keep one keyway across a mix of functions.
12) Is a Grade 2 lever lock good enough, or do I need Grade 1 like the Sargent 11 Line?
Grade 1 is the heavy duty commercial tier and is what gets specified for schools, hospitals and high-traffic public buildings; the Sargent 11 Line sits there with a 7.6 million cycle UL test behind it. For lighter interior traffic, offices and closets, a Grade 2 lever such as the Falcon B101 passage or the Hager 2510 passage is the usual step down. On a rated stair or corridor door, stay with Grade 1.
13) If Grade 1 is more than the door needs, what lighter-duty non-keyed lever can replace the Sargent 11G13?
The Sargent 11G13 is a Grade 1 heavy duty commercial cylindrical leverset. For lower-traffic openings, Grade 2 non-keyed levers include the Falcon B101 medium duty passage lever with a non-handed design, the Accentra 5301LN Augusta Grade 2 passage/closet lever, the Arrow GL01 Grade 2 passage lever with Sierra lever for 1-3/4 inch to 2 inch doors, and the Hager 2510 Grade 2 passage lever with Withnell design for 1-3/8 inch to 2 inch doors. All are passage rather than exit function, so confirm the door does not need one-sided operation.
14) What is the difference between the Sargent 11G13 and an electrified cylindrical lever like the Corbin Russwin CL33903?
The Sargent 11G13 is a mechanical non-keyed cylindrical leverset with exit latch function and no electrical component. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever operating on 12VAC/DC for 1-3/4 inch to 2 inch doors, which requires power transfer to the door and ties into an access control system. Choose the CL33903 when the opening must unlock on signal or loss of power; choose the 11G13 when the opening is mechanically egress-only.
15) Is a residential-grade lever like the Kwikset 200BRNL an acceptable substitute for the Sargent 11G13?
Not for a commercial opening. The Sargent 11G13 is a Grade 1 heavy duty lock specified for commercial use. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors, and the Callan Asheville is a Grade 3 passage leverset. Those suit interior residential hall and closet doors rather than high-traffic commercial doors, and they will not meet a Grade 1 line on a hardware schedule.
16) I need a knob instead of a lever for the same kind of opening as the Sargent 11G13. What are the options?
The Sargent 11G13 is a lever-handled cylindrical lock and is not offered with knob trim. Knob-style cylindrical locks in the comparable range include the Arrow MK02-TA Grade 2 privacy lock with a Tudor knob for 1-3/4 inch to 2 inch doors, the Arrow MK33-BD-CS heavy duty asylum lock with a ball knob and conventional cylinder in the Schlage C keyway, and the Arrow HK11-BB entrance lock with ball knob for 1-3/8 inch to 1-3/4 inch doors. Note that levers are generally preferred where ADA operable-hardware requirements apply.
17) What should I use instead of the Sargent 11G13 on an institutional door that needs to be secured from both sides?
The Sargent 11G13 is exit only, so it always allows free egress from the inside. Where a room must be controlled from both faces, asylum or institutional function locks are the substitute: the Dexter C1000 Grade 1 asylum lock (F87) covers 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum function lock with a conventional cylinder in the Schlage C keyway. Verify local egress code before specifying either on an occupied space.
18) Does the Sargent 11 Line help with LEED or healthcare infection control requirements?
Two things apply. The lock is made from 68 percent post-consumer recycled content per LEED MR credit 4, which procurement teams use on green building submittals. There is also an optional Microshield antimicrobial coating on the high-touch lock surfaces, which is why it shows up in healthcare and school specs alongside cleaning protocols.
