Sargent 28-10G24-LL-10B – Frequently Asked Questions

1) What does the Entrance/Office function do on the Sargent 10 Line 28-10G24 lockset?
Entrance/Office is the function where the outside lever can be locked, and the inside lever always retracts the latch for free egress. It's the usual choice for tenant suite doors, offices and staff rooms where someone secures the door from inside at the end of the day. The 10 Line is a cylindrical (bored) lock, Grade 1, heavy duty.
2) What backset does the Sargent 10 Line lever lock use, and can it work in an existing 2-3/8 inch prep?
Standard backset is 2-3/4 inches, which is the normal commercial bore location. For retrofit work the 10 Line also takes optional latches at 2-3/8 inch, 3-3/4 inch and 5 inch backsets, so an older door bored at 2-3/8 or a wide-stile opening at 5 inches can be covered by specifying the right latch rather than re-prepping the door.
3) Will the Sargent 10 Line lever lock latch into my existing frame strike?
It ships with the 808 ANSI strike, which is the standard 4-7/8 inch ANSI strike prep found in most commercial hollow metal frames. If your frame is already cut for an ANSI 4-7/8 strike, it drops straight in. Frames with a small T-strike or residential round-corner cutout will need the frame prepped or the existing opening modified.
4) Is the Sargent 10 Line lever handed, and do I need to specify left or right?
No handing to specify. The 10 Line lever lock is non-handed, and the B, L, J and P levers are all non-handed ADA styles. That's why facilities stock it: one part number covers left and right hand openings, which cuts what you have to warehouse.
5) What keyway does the Sargent 10 Line use and can it go on a high security key system?
The LA keyway is the Sargent profile it comes set up for, so it keys into an existing Sargent LA system without a cylinder swap. For higher security the 10 Line also works with Signature Keso, BR-XC and XC key systems. Note that the 28-10G24 as listed is supplied non-keyed, so the cylinder and keying are specified separately.
6) What is the closest cross-brand match to the Sargent 28-10G24 for an entrance/office opening?
The Sargent 28-10G24 is a Grade 1 cylindrical entrance/office leverset. If you need the same entrance/office function from another brand, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever lock with entry/office function, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever. The Sargent sits at Grade 1 heavy duty, so on a high-traffic office door the Falcon and Cal-Royal step down in duty rating while keeping the same lock function.
7) I need a Grade 1 lever lock for a door thicker than standard - does the Sargent 28-10G24 or something else fit?
The Sargent 28-10G24 is specified with a 2-3/4 inch backset and is a Grade 1 heavy duty cylindrical lever. If your door thickness is the deciding factor, the Falcon K101 is a Grade 1 heavy duty cylindrical lock rated for 1-3/8 inch to 2-1/4 inch doors, and the Dexter C1000 asylum version covers 1-3/8 inch to 2 inch. Note those two are passage and asylum functions respectively, not entrance/office, so you would be changing how the door locks as well.
8) What should I use instead of the Sargent 28-10G24 on a classroom door?
The Sargent 28-10G24 is an entrance/office function lock, which is not the right function for a classroom opening. For that door, the Dexter C1000 classroom lever is Grade 1 with a clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, the Dexter C1000 classroom security version is Grade 1 with the same clutching keyed design, and the Cal-Royal AG03 is a Grade 2 classroom lever on a 2-3/4 inch backset, matching the Sargent's backset.
9) What looks like a substitute for the Sargent 28-10G24 but will not work on an office entry door?
Dummy trim is the most common mistake. The Accentra 455LN Augusta, BEST 9K 1DT and BEST 7KC 1DT single dummy levers, and the Callan Bentley BN5051 are dummy function only - they have no latch and no locking mechanism, so they mount as a pull, not as a working lock like the Sargent 28-10G24 entrance/office lockset. Privacy levers such as the Hager 2540 and the Kwikset 300BRNL Breton are also not equivalents; privacy trim locks from the inside with no key control.
10) The Sargent 28-10G24 uses the LA keyway - what if my building is keyed to Schlage C?
The Sargent 28-10G24 is specified with the LA keyway. If your masterkey system runs Schlage C, the Cal-Royal AG00 entrance lever and AG03 classroom lever are supplied with 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock uses a conventional cylinder in Schlage C keyway. Matching the keyway to the existing system avoids carrying a second key on the route.
11) Which lever and finish combinations can I order on the Sargent 28-10G24?
Two lever styles, B and L, each in 10 Satin Bronze clear coated or 26D Satin Chromium Plated over Nickel. 26D is the usual match for commercial openings already running satin chrome hardware; 10 suits bronze-toned buildings. The broader 10 Line offers 11 architectural finishes including the Coastal Series Gulfport and Yarmouth designs.
12) How durable is the Sargent 10 Line lockset for a high-traffic door?
Tested past 4 million cycles, which is five times the Grade 1 requirement under ANSI 156.2 Series 4000, and it takes more than double the standard abusive locked-lever torque without releasing. The lever is one-piece cast rather than assembled tube. For a main corridor, a school classroom wing or a hospital door that sees constant use, that's the reason to spend up from a Grade 2 lock.
13) What are the other Grade 1 cylindrical lever locks comparable to the Sargent 10 Line?
Across the same class: Corbin Russwin CL3100 Series (CL3110 is the vandal resistant passage version, fire rated, 1-3/4 to 2 inch doors), Falcon K Series K101, a Grade 1 heavy duty fire rated lever for 1-3/8 to 2-1/4 inch doors, and the Dexter C1000 Series, Grade 1 in classroom, classroom security and passage functions. Those listed versions are non-keyed or other functions, so match the function you need before substituting for an entrance/office opening.
14) Is there a vandal resistant version of the Sargent 10 Line for an abuse-prone door?
Yes. Free Wheeling (FW) trim is available on the 10 Line for high-abuse environments, where the outside lever spins freely when locked instead of transferring force into the lock body. It's offered with classroom security and other locking functions. If the door is in a corridor or a public restroom where levers get hung on, specify FW.
15) Can I standardize a whole building on the Sargent 10 Line and mix functions door to door?
That's how it's usually spec'd. The same 10 Line bored chassis, 2-3/4 inch backset and 808 ANSI strike prep run through the building, and you change function door by door, entrance/office on suites, and the line also covers classroom security and other locking functions with the FW trim. Levers are non-handed, so one lever part number stocks both hands for the whole facility.
16) Does the Sargent 10 Line lever meet ADA requirements for an accessible opening?
The lever styles are ADA compliant, with six ADA lever designs in the 10 Line including the non-handed B, L, J and P levers. The B and L levers are the two offered on the 28-10G24. A lever handle rather than a knob is what accessible openings require, so this is the correct trim type for an ADA path of travel.
17) Is there a simpler non-locking lever I can use on interior doors alongside the Sargent 28-10G24?
Yes. The Sargent 28-10G24 controls entrance/office function, which is more than an interior corridor or closet door needs. For those openings, the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 inch to 2 inch doors; the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release; and Design Hardware X75 is a Grade 1 passage lever with a flat lever for 1-3/4 inch doors. All three keep Grade 1 durability while dropping the locking function.
18) I need a storeroom function instead of entrance/office - what replaces the Sargent 28-10G24?
The Sargent 28-10G24 is entrance/office, where the lever can be left unlocked. For an always-locked storeroom door, 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 with Withnell lever is a Grade 2 storeroom cylindrical lock for 1-3/8 inch to 2 inch doors. Both are Grade 2 rather than the Sargent's Grade 1.
19) If I want keypad or electrified access control rather than the keyed Sargent 28-10G24, what are the options?
The Sargent 28-10G24 is a mechanical cylindrical leverset. For credential or code-based control on the same style of opening, the Corbin Russwin CL33903 is a Grade 1 electrified fail safe cylindrical lever running on 12VAC/DC for 1-3/4 inch to 2 inch doors, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 1150 is a mechanical keypad lever set for 1-1/8 inch to 2 inch doors. The Corbin Russwin requires power to the door; the Delaney and Lockey do not.
20) Is the Arrow HK11-BB an equivalent to the Sargent 28-10G24?
Not directly. The Arrow HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for 1-3/8 inch to 1-3/4 inch doors. The Sargent 28-10G24 uses a lever handle, which is the trim style required where ADA lever operation is specified. If you are replacing knobs with levers across a building, the Sargent is the lever equivalent of that entrance function.
21) Is the Sargent 10 Line a residential lock or strictly commercial?
Commercial. It's a heavy duty Grade 1 bored lever lock built for office buildings, schools, healthcare, government and multi-tenant properties. For a house or light interior work, a Grade 3 set like the Kwikset 200BRNL Breton passage lever is the right class of product instead; putting a 10 Line on an interior closet door is money spent on cycle life nobody will use.
22) What lever options exist for residential-grade doors where the Sargent 28-10G24 is more lock than needed?
The Sargent 28-10G24 is a commercial Grade 1 heavy duty leverset. On light residential or light-traffic interior doors, the Callan Artino 360201 is a Grade 3 entrance leverset, the Callan Bennett BN3001R is a Grade 3 entrance leverset with a deadbolt combo, and the Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 to 1-3/4 inch doors. These are Grade 3 rather than Grade 1, so they suit lower cycle counts than a commercial office entry.
