Sargent 10XG38 LB 26D – Frequently Asked Questions

1) Will the Sargent 10XG38 fit a 1-3/8 inch door, and what about a thicker 2 inch door?
Both work. The 10X Line classroom security lock covers door thickness from 1-3/8 inches through 2 inches, which takes in older 1-3/8 inch interior doors as well as standard 1-3/4 inch commercial doors and heavier 2 inch leaves. No separate thickness kit to specify.
2) Do I have to worry about handing when ordering the Sargent 10X classroom security lever?
No. The 10X Line cylindrical lock is non-handed, so one part number covers left and right hand doors. You still need to pick lever style (B, L, or P), rose style (G or L), finish, backset, strike, and the cylinder and keying options.
3) Can I key this Sargent lock into our existing small format interchangeable core system?
Yes. The 10XG38 can be ordered with a 70 Sargent small format interchangeable core prep, a 60 large format interchangeable core, or a conventional 6 pin standard cylinder. The lockbody accepts all cylinder formats from fixed to interchangeable core and all Sargent key systems, so it drops into an existing Sargent keyed facility.
4) What is the difference between a classroom security lock like the Sargent 10XG38 and a standard classroom lock?
A standard classroom function, such as the Dexter C1000 classroom lever lock, is keyed on the outside only - the lever is locked and unlocked with a key from the corridor side. The Sargent 10XG38 is a double cylinder classroom security lock, with a cylinder on both sides, so a teacher can lock the outside lever from inside the room without stepping into the hallway. If lockdown from inside the classroom is a requirement, the standard classroom function will not satisfy it.
5) What is the closest cross-brand equivalent to the Sargent 10XG38 classroom security lock?
The Dexter C1000 series classroom security lever lock is the nearest match in function and grade. Both are Grade 1 keyed cylindrical lever locks carrying the classroom security function, meaning two cylinders so the door can be locked or unlocked from either side without opening it. The Dexter C1000 classroom security model lists a door thickness range of 1-3/8 inch to 1-3/4 inch, while the Sargent 10XG38 covers 1-3/8 inch to 2 inch, so on a door thicker than 1-3/4 inch the Sargent is the one that fits.
6) What keyways and keying options can I specify on the Sargent 10X classroom security lock?
LA is the standard keyway, and 40 more Sargent keyways are selectable: CA, CB, CC, CE, CF, CG, CJ, CK, CL, CR, HA, HB, HC, HE, HF, HG, HH, HJ, HK, LB, LC, LE, LF, LG, LJ, LK, LL, R, RA, RB, RC, RE, RF, RG, RJ, RK, RL, S, and U. Keying is ordered as standard keying, KD keyed different, KA keyed alike, or MK master keyed, so a school can run these on an existing master system.
7) Sargent 10XG38 or Dexter C1000 classroom security lever - what is the difference?
Both are Grade 1 cylindrical classroom security locks. The Dexter C1000 classroom security model lists a door thickness range of 1-3/8 to 1-3/4 inches, while the Sargent 10X classroom security covers 1-3/8 to 2 inches, so the Sargent is the one for a 2 inch leaf. The Sargent also offers backsets out to 5 inches and Sargent FSIC or SFIC core prep for facilities already on a Sargent key system.
8) We just need a keyed classroom lock without the inside cylinder. Is there a cheaper alternative to the Sargent 10XG38?
If you do not need to lock the outside lever from inside the room, a standard classroom function is enough. The Dexter C1000 classroom lever is a Grade 1 clutching classroom lock, and the Cal-Royal AG03 is a Grade 2 classroom lever with a 6 pin Schlage C keyway and 2-3/4 inch backset. Neither gives you the inside-key lockdown that the double cylinder 10XG38 provides, so only step down if lockdown from inside the classroom is not part of your security plan.
9) Does the Sargent 10X cylindrical lock meet Florida Building Code for hurricane zones?
The lock is windstorm certified to comply with Florida Building Code requirements and UL listings, which is what lets it be used on openings in hurricane-prone regions where the door assembly has to hold up under extreme wind pressure.
10) Is the Cal-Royal AG03 classroom lever a substitute for the Sargent 10XG38?
They are not the same function. The Cal-Royal AG03 is a classroom lever with a 2-3/4 inch backset in the AG series, keyed from the outside with a Schlage C keyway. The Sargent 10XG38 is a double cylinder classroom security lock rated Grade 1 heavy duty, with cylinder options covering 6-pin standard, Sargent large format interchangeable core and small format interchangeable core across the full range of Sargent keyways. Use the AG03 only where outside-only keying is acceptable and a Schlage C keyway suits the existing system.
11) We need a Grade 1 lever on the same classroom doors but with no keying - what should we order?
For the non-keyed openings in the same run, Grade 1 cylindrical passage levers include the Falcon K101, which lists a door thickness range of 1-3/8 inch to 2-1/4 inch and is fire rated, the Falcon T101 heavy duty passage lever, the Corbin Russwin CL3110 vandal resistant passage lever, and the Dexter C1000 passage lever. All carry Grade 1 like the Sargent 10XG38, so the openings stay at one grade while only the keyed classroom security doors take the 10XG38.
12) Is a Grade 2 storeroom lever an acceptable alternative to the Sargent 10XG38 on a classroom door?
Only if the opening does not need classroom security behavior. Grade 2 storeroom levers such as the Cal-Royal AG05, which lists a deadlocking latchbolt and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Hager 2580 with the Withnell lever, keep the outside lever locked at all times and are released by key. The Sargent 10XG38 is Grade 1 and double cylinder, so the outside lever can be locked or unlocked from the inside as conditions change. Storeroom function gives no inside key control of the outside lever.
13) What should I use instead of the Sargent 10XG38 if the door needs electric access control?
For an electrified cylindrical opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock in 12VAC/DC, listed for 1-3/4 inch to 2 inch doors, with a version offered on the NZ lever and D rose. The Sargent 10XG38 is the mechanical double cylinder classroom security lock in the 10X Line; the 10X Line does offer electromechanical functions with Wave to Open, Request to Exit and Door Position Switch options if you want to stay within Sargent.
14) For a healthcare or behavioral health door, should I specify the Sargent 10XG38 or an asylum function lock?
Asylum function is the one to look at there: the Dexter C1000 asylum lock is Grade 1 with an F87 function and a 1-3/8 inch to 2 inch door thickness range, and the Arrow MK33-BD-CS is a heavy duty asylum lock on a ball knob with a conventional Schlage C keyway. Asylum function keeps both levers keyed and always locked. The Sargent 10XG38 classroom security function also uses cylinders on both sides but allows free egress lever operation, which is what a classroom needs.
15) What finishes does the Sargent 10X classroom security lever come in for matching existing school hardware?
Fourteen finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze lacquered, 26 bright chrome, 26D satin chrome, plus BSP black suede and WSP white suede powder coats. 26D is the usual match for institutional openings.
16) Can I use the Sargent 10X line for electrified openings with request to exit or door position switch?
Yes, the 10X Line offers electromechanical functions with Wave to Open, Request to Exit, or Door Position Switches, using Sargent EcoFlex technology for reduced power draw. Those are a different ordering path from the mechanical 10XG38 classroom security lock, and Sargent publishes a separate installation instruction for the 10X Line electrified bored lock.
17) Is there an antimicrobial option on the Sargent 10X lever for a healthcare or school setting?
Optional Microshield antimicrobial coating is available on the 10X Line, which is what facilities spec for clinics, patient rooms, and high touch school corridors. It is an added coating option rather than a different lock body.
18) What is a Grade 1 dummy lever to pair with Sargent 10XG38 openings on inactive leaves?
The BEST 9K series 1DT single dummy trim cylindrical lever is a Grade 1 heavy duty non-keyed dummy, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever in the 5400 series. Either holds the grade line on inactive leaves while the operating leaves carry the Sargent 10XG38 Grade 1 classroom security lock. A dummy has no latch and no cylinder, so it is for pull-only leaves.
19) Would a keypad leverset work in place of the Sargent 10XG38 on a classroom door?
They solve different problems. The Delaney LP250 is a Grade 2 electronic keypad leverlock and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function, listed for 1-1/8 inch to 2 inch doors. Neither provides the double cylinder classroom security arrangement of the Sargent 10XG38, which is Grade 1 and keyed on both sides so the outside lever can be secured from within the room. Keypads suit code-managed offices and storage rather than classroom lockdown.
