Sargent 28-11G38 LB 26D – Frequently Asked Questions

1) What does the classroom security function on the Sargent 11G38 actually do?
The 11G38 is a double cylinder classroom security lock, meaning there is a key cylinder on both the outside and the inside. A teacher can lock the outside lever from inside the room with a key without opening the door and stepping into the corridor, and the inside lever always retracts the latch for free egress. That is the difference from a standard classroom function, where the outside lever can only be locked with a key from the corridor side.
2) Can the Sargent 11G38 be keyed into our existing school master key system?
It accepts SARGENT key systems including Degree and Signature, plus SFIC, and Schlage and Medeco LFIC. On the order you pick the cylinder type (6 pin standard, 60 Sargent large format interchangeable core, or 70 Sargent small format interchangeable core), the keying (keyed different, keyed alike, or master keyed) and the keyway, with LA as the standard and 40 keyways available including the CA through CR, HA through HK, LB through LL, R, RA through RL, S and U families.
3) Is the Sargent 11G38 rated for a high traffic school corridor?
It is ANSI/BHMA A156.2 Series 4000 Grade 1, heavy duty, and independently verified to 7.6 million cycles under UL Verification ID V584148. T-Zone construction resists twisting on the lever, which is the usual failure mode when students hang on a corridor lever.
4) I only need a standard classroom lock, not classroom security - what should I order instead?
A standard classroom function keys from the outside only and has no inside cylinder. The Dexter C1000 Series classroom lever lock is a Grade 1 clutching cylindrical lever with a Classroom function, for doors 1-3/8 inch to 1-3/4 inch thick. The Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset. The Sargent 11G38 is the double-cylinder classroom security version, which adds an inside cylinder so a teacher can lock the door from within the room.
5) Do I need to specify handing when ordering the Sargent 11 Line 11G38?
No handing to specify. The 11G38 is non-handed, so one lock covers left and right hand openings and you do not need to stock both versions for a building.
6) If the function needs to change later, do I have to replace the whole Sargent 11G38 lock?
No. The 11 Line uses a modular design and functions can be changed in the field without swapping out the lock, and the cylinder pulls with a simple removal system. For a facility that re-purposes rooms, that means a classroom security opening can be converted without re-prepping the door.
7) What lever, rose and finish combinations can I get on the Sargent 11 Line classroom security lock?
Levers come in B, J, L and P designs. Roses are the B and O at 2-3/4 inches, the L at 3-1/8 inches, and the E at 3-1/2 inches, which matters if you are covering scarring from previous hardware. Finishes run 14 options: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed, 10BE, 10BL, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, plus BSP black and WSP white suede powder coat. 26D is the usual match for existing institutional hardware.
8) Do I need through bolts or surface screws to install the Sargent 11G38?
No. The T-Zone mounting system holds the lock without through bolts or surface screws, so there is nothing exposed on the door face to attack or loosen. Install to a standard 161 prep using the manufacturer templates and torque the mounting per the installation instructions.
9) We need Grade 1 lever locks for a school but not every door needs a keyed classroom function. What else works with these?
For the openings that just need free passage, Grade 1 non-keyed cylindrical levers that sit alongside a classroom security lock include the Falcon K101, which covers 1-3/8 to 2-1/4 inch doors and is fire rated, the Corbin Russwin CL3110 vandal resistant passage for 1-3/4 to 2 inch doors, and the Falcon T101 heavy duty passage. Keep the 11G38 on the classrooms themselves, where the inside key cylinder is what gives the lockdown capability.
10) What should I use on the non-classroom doors in the same corridor to match the Sargent 11G38?
For corridor and closet doors that do not need keying, the Falcon K101 is a Grade 1 heavy duty cylindrical passage lock with non-handed levers, fire rated, for doors 1-3/8 inch to 2-1/4 inch. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for 1-3/4 inch to 2 inch doors. For a storeroom door, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. The Sargent 11G38 itself is non-handed, and its modular design allows functions to be changed in the field without replacing the lock.
11) Is the Dexter C1000 asylum lock a substitute for the Sargent 11G38 classroom security lock?
No. The Dexter C1000 F87 is a Grade 1 cylindrical lock with an Asylum/Institution/Utility function, meaning both sides are key operated at all times with no free egress lever action of a classroom lock. The Sargent 11G38 is a Grade 1 double-cylinder Classroom Security lock, where the inside cylinder locks the outside lever and the inside lever always retracts the latch. The Arrow MK33-BD is also an asylum function lock, supplied as a ball knob with a Schlage C keyway, so it is not a lever trim match either.
12) We need an electrified lever on one classroom door - what pairs with the Sargent 11G38?
The Corbin Russwin CL33903 is a Grade 1 electrified fail safe cylindrical lever lock operating on 12V AC/DC, for doors 1-3/4 inch to 2 inch thick, and is available with the NZ lever and D rose or as a keyed version. The Sargent 11G38 is a mechanical double-cylinder classroom security lock with no electrification, so use the CL33903 where an access control tie-in is required and the 11G38 on the mechanical openings.
13) Does the Sargent 11 Line count toward LEED credits on a school project?
The lock is built from 68 percent post-consumer recycled content, which is stated as meeting LEED MR credit 4 requirements. That is the figure to hand your sustainability consultant on a green building submittal.
14) Can I use a keypad lever instead of the Sargent 11G38 to avoid issuing keys?
There are keyless options, but they are different animals. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in a passage function, fitting doors 1-1/8 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock. Neither provides the Grade 1 double-cylinder classroom security operation of the Sargent 11G38, which lets staff lock the outside lever from inside the room using a key and accepts Sargent Degree and Signature, SFIC, and Schlage and Medeco LFIC cylinders.
15) Is a Grade 1 dummy trim available to match a Sargent 11G38 lever on an inactive leaf?
The BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim cylindrical lever, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever from the 5400 Series. Both are trim only with no latch, for inactive leaves. They will not carry the Sargent B, J, L or P lever or the Sargent rose sizes, so the visual match to the 11G38 will not be exact.
