Sargent 10XG08 LB 26D – Frequently Asked Questions

1) Will the Sargent 10XG08 classroom lock fit a 1-3/8 inch door?
Yes. The 10X Line 10XG08 cylindrical lock covers door thicknesses from 1-3/8 inch through 2 inch, so it drops onto older 1-3/8 inch interior classroom doors as well as standard 1-3/4 inch commercial doors and thicker 2 inch leaves. One lock body handles the whole range, which is useful when a building has a mix of vintages.
2) Do I have to specify handing on a Sargent 10X classroom lever lock?
No handing to specify. The 10XG08 is non-handed, so the same lock works on a left or right hand door and you do not need to know the swing before ordering. That also means a distributor can stock one part for both hands across a school.
3) What does the communicating classroom function on the Sargent 10XG08 actually do?
Communicating/classroom function on the 10XG08 is a single cylinder lock: the key works one side, and the outside lever is locked or unlocked by key rather than by a button on the inside. It is the function used where staff control access from the corridor side and the room side stays free-egress. If you need the teacher to be able to lock the door from inside the room without stepping into the hallway, that is a classroom security function instead, such as the Dexter C1000 Classroom Security.
4) Can I get the Sargent 10XG08 with an interchangeable core so I can key it myself?
Yes. Cylinder format is a required selection: a 6 pin standard conventional cylinder, the 60 prefix for Sargent large format interchangeable core (FSIC), or the 70 prefix for small format interchangeable core (SFIC). Facilities that rekey in-house usually take 60 or 70 so a locksmith can pull and swap a core with a control key instead of taking the lock apart. The lock body accepts all of these formats and all Sargent key systems.
5) Can Sargent 10X classroom locks be keyed alike or put on our building master key system?
Keying is specified on the order: keyed different (KD), keyed alike (KA), master keyed (MK), or standard keying. Keyway is a separate selection with 41 choices, LA being the standard, plus the CA through CR, HA through HK, LB through LL, R, RA through RL, S and U keyways. If you are adding doors to an existing Sargent system, give the same keyway and master key bitting your other openings already use and the new locks fold straight into the system.
6) What is the closest Grade 1 classroom cylindrical lever lock to the Sargent 10XG08?
The Dexter C1000 Series classroom cylindrical lever lock is the nearest peer in function and grade: it is a Grade 1 clutching keyed classroom lever with a 1-3/8 inch to 1-3/4 inch door thickness range. The Sargent 10XG08 is a Grade 1 heavy duty cylindrical lever with a communicating/classroom function and covers 1-3/8 inch to 2 inch doors, so it reaches thicker doors than the Dexter. The Sargent also runs a much wider keying program - 6 pin standard, Sargent large format interchangeable core (60) and small format interchangeable core (70) across roughly 40 keyways - where the Dexter is offered as a keyed classroom lock without that cylinder range.
7) For a classroom door where the teacher must be able to lock the door from inside during a lockdown, what should be used instead of a communicating classroom lock?
Look at the Dexter C1000 Series classroom security lever, a Grade 1 clutching keyed lock built for the classroom security function on 1-3/8 inch to 1-3/4 inch doors. A classroom security function is keyed on both sides so the room can be secured from inside without opening the door. The Sargent 10XG08 is a communicating/classroom single cylinder lock, so the keyed control is on one side only. Sargent's 10X lockbody family covers a broad function range, so a different 10X function number is the other route if the opening must stay in the Sargent keyway program.
8) Can I use the Sargent 10X lock on a school in a hurricane zone in Florida?
Windstorm certified to comply with Florida Building Code requirements, and UL listed. That makes it usable on openings in hurricane-prone regions where the door assembly has to hold up under extreme weather loading. Confirm the certification covers your specific door and frame assembly, since windstorm approval is assembly-based.
9) What lever and rose styles can I get on the Sargent 10X, and can I match the black hardware on our other doors?
Three lever designs (B, L and P) and two rose shapes (G rose and L rose). Finishes run to fourteen: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE, 10BL, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, BSP black suede powder coat and WSP white suede powder coat. BSP is the one to specify for a black hardware package, and 26D satin chrome is the usual institutional default.
10) What is a Grade 1 alternative to the Sargent 10X classroom lock from another brand?
Two close options if you are cross-shopping Grade 1 cylindrical classroom hardware. The Dexter C1000 Series classroom lever lock is Grade 1 with a clutching lever, keyed, and covers 1-3/8 inch to 1-3/4 inch doors. The Corbin Russwin CL3300 Series is the other Grade 1 cylindrical family here. The Sargent 10X carries the wider 1-3/8 inch to 2 inch door range and the 20 million cycle test, so on thicker leaves or a genuinely abusive opening it is the one that still fits.
11) I only need a passage or storeroom lever on the same doors, not a classroom function. What should I look at?
Classroom function is the wrong buy for a door that never locks or always locks. For a Grade 1 passage lever, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch doors, is fire rated and non-handed, or the Corbin Russwin CL3110 passage/closet is Grade 1 vandal resistant and fire rated for 1-3/4 inch to 2 inch doors. For storeroom function, where the outside lever is always locked and the key retracts the latch, the Hager 2580 with the Withnell lever is a Grade 2 option for 1-3/8 inch to 2 inch doors.
12) What Grade 1 lever should go on the corridor and closet doors that do not need to be keyed, alongside Sargent 10XG08 classroom locks?
Two Grade 1 non-keyed peers fit that role. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever, fire rated, for 1-3/4 inch to 2 inch doors. Both leave out the cylinder entirely, so they carry no keyway decision. The Sargent 10XG08 is keyed, single cylinder, and non-handed, so a mixed opening schedule of 10XG08 classroom doors and either passage lever keeps the same lever-operated cylindrical prep.
13) Can a Grade 2 cylindrical lever be used on a high traffic school corridor instead of a Grade 1?
It is a different durability class. Peers such as the Hager 2580 storeroom lever and the Cal-Royal AG05 storeroom lockset are Grade 2, and the Falcon B511CP6D entry/office lever is Grade 2 medium duty. The Sargent 10XG08 is Grade 1 heavy duty and was tested to 20 million cycles under the UL Cycle Above and Beyond program, holding more than 3,100 in-lb locked lever torque and 1,600 lbs offset lever pull. Where a specification calls for ANSI/BHMA Grade 1, a Grade 2 lever does not meet it regardless of function match.
14) What is the difference between a Sargent 10XG08 and an asylum or institutional function lever?
Function, not build class. The Dexter C1000 Series asylum lock (F87) is a Grade 1 asylum/institution/utility lever for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum lever with a conventional cylinder in the Schlage C keyway on a ball knob. An asylum function is keyed on both sides so neither side is free-turning. The Sargent 10XG08 is a single cylinder communicating/classroom lever, so one side operates without a key. Pick by which sides of the opening need key control.
15) Does an electrified cylindrical lever replace a Sargent 10XG08 on an access controlled classroom door?
Only if the opening is being wired. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for 1-3/4 inch to 2 inch doors - it releases on loss of power and needs a power transfer and a wired frame. The Sargent 10XG08 is a mechanical single cylinder classroom lock; the 10X lockbody family does include electromechanical functions if the door is later brought onto access control, and 10X electrified bored lock installation instructions are published separately from the mechanical set.
16) Will a residential grade lever work on a school or office door that calls for a Sargent 10XG08?
No. Peers like the Kwikset 200BRNL Breton passage lever and the Kwikset 300BRNL Breton privacy lever are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AUS00 entrance/office lever is Grade 3. The Sargent 10XG08 is a Grade 1 commercial cylindrical lock rated heavy duty for 1-3/8 inch to 2 inch doors, with UL certification and windstorm compliance to Florida Building Code. Grade 3 hardware does not answer a Grade 1 line on a door schedule.
17) Will the Sargent 10X lever get damaged where the door swings back against a wall?
The 10X uses a push/turn button design specifically so the button is not sheared off by door stops or a wall on the backswing, which is the usual failure point on button-operated cylindrical locks in tight corridors. The family offers 26 mechanical and 2 electromechanical functions, so if you need an electrified version on the same door prep it exists within the line.
18) Is the Sargent 10XG08 suitable for anything besides schools, like a hospital or an apartment building?
It is a commercial-rated lock, not residential, and the communicating/classroom function shows up well beyond education. Healthcare rooms, government and municipal buildings, commercial offices, multi-tenant residential, and industrial or warehouse doors all use this function where the corridor side is key-controlled. The Grade 1 heavy duty build is aimed at high-traffic openings, so it is over-specified for a low-use interior door where a Grade 2 lever would do.
19) Is a keypad lever an alternative to a keyed classroom lock?
It changes how the door is controlled. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Both credential the user by code rather than key. The Sargent 10XG08 is a keyed lock whose lockbody accepts all Sargent key systems from fixed cylinder to interchangeable core, which is what keeps a classroom door on the building master key. A keypad lever takes that door off the key system.
20) What Grade 1 lever pairs with a Sargent 10XG08 on a door that needs a decorative or designer trim look?
The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors, and the Falcon T101 is a Grade 1 heavy duty cylindrical passage lever with pressure release technology. Both hold Grade 1 while changing the lever profile. On the Sargent 10XG08 the trim decision is made within the same lock: B, L and P levers, G and L roses, and fourteen finishes from 26D satin chromium and 15 satin nickel through 10B oil rubbed bronze and BSP black suede powder coat.
