Sargent 28-10G24 LB 26D – Frequently Asked Questions

1) Does the Sargent 28-10G24 cylindrical lock need to be ordered left or right hand?
No handing to specify. The 28-10G24 is a non-handed cylindrical lever lock, so one part number covers both swings. That is useful if you stock spares across a building, since a single SKU covers every opening rather than two.
2) What function is the Sargent 10G24 lock, and where should it be used?
The 10G24 is an entrance/office function lever lock, so the outside lever can be locked and unlocked and the inside lever always retracts the latch for free egress. It suits tenant office doors, suites, and similar openings where staff lock up behind themselves. If you need a door that stays locked outside at all times and is only opened by key, a storeroom function such as the Cal-Royal AG05 or the Hager 2580 is the right call instead.
3) Is this Sargent lever lock Grade 1 for high traffic commercial doors?
Yes, the 28-10G24 carries BHMA Grade 1 certification, the top ANSI/BHMA cylindrical lock grade, which is what specs typically call for on schools, healthcare corridors, and high-use office entries. Grade 2 lever locks like the Hager 2525 entrance lock or Falcon B511 entry/office lock cover lighter traffic openings at the same function.
4) Can the Sargent 28-10G24 be master keyed into an existing system?
It ships with a conventional cylinder, which is the standard pin tumbler format used for keying and master keying, so it drops into a conventional Sargent key system. If your facility runs interchangeable core instead, this is not the right configuration and you want a small format IC lock such as the BEST 9K Series.
5) What is a Grade 1 alternative to the Sargent 28-10G24 LB entrance/office lever for a commercial office door?
The Sargent 28-10G24 LB is a Grade 1 cylindrical lever lock for entrance and office use with a conventional cylinder and a non-handed body. If you need another Grade 1 cylindrical lever, the Dexter C1000 Series Classroom lock is Grade 1 with a clutching lever and fits doors 1-3/8 inch to 1-3/4 inch, and the Corbin Russwin CL33903 is a Grade 1 electrified fail safe lever for 1-3/4 inch to 2 inch doors. Note that neither is an entrance/office function, so confirm the function code matches the opening before substituting.
6) Is there a lighter-duty entrance/office lever than the Sargent 28-10G24 LB for a low-traffic tenant door?
Yes. The Sargent 28-10G24 LB is Grade 1 for high-traffic commercial use. For lighter traffic, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever in entry/office function, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body that fits doors 1-3/8 inch to 1-3/4 inch. Both keep the same entrance/office operating behavior at a lower ANSI/BHMA grade.
7) I need a storeroom function instead of the Sargent 28-10G24 LB entrance/office - what else works?
Entrance/office on the 28-10G24 LB lets the lever be left unlocked by pushbutton, which is not what a storeroom door wants. For always-locked outside trim, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors.
8) What should I use instead of the Sargent 28-10G24 LB on a classroom or patient-room door?
The 28-10G24 LB is an entrance/office lock, which is not the function specified for classrooms or institutional rooms. For a classroom, the Dexter C1000 Classroom is Grade 1 with a clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, and the C1000 Classroom Security version adds inside keyed control. For asylum/institution/utility openings where both sides are keyed, the Dexter C1000 Asylum is Grade 1 and fits 1-3/8 inch to 2 inch doors.
9) I need access control on the door - what replaces the Sargent 28-10G24 LB mechanical lever?
The 28-10G24 LB is a mechanical lock with a conventional key cylinder. For credential or code entry on a cylindrical prep, the Corbin Russwin CL33903 is a Grade 1 electrified fail safe lever running 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 in passage function for doors 1-1/8 inch to 2 inch. Only the Corbin Russwin option holds a Grade 1 rating like the Sargent.
10) I need a Schlage C keyway on the door instead of the Sargent cylinder - what lever locks use that keyway?
The Sargent 28-10G24 LB ships with a conventional Sargent cylinder for master keying within a Sargent system. If your building is keyed to Schlage C, the Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, the Cal-Royal AG03 classroom lever uses the same 6-pin Schlage C keyway with a 2-3/4 inch backset, and the Arrow MK33-BD-CS is a Grade 2 asylum lock with a conventional Schlage C keyway cylinder.
11) What does 26D finish mean on a Sargent lever lock, and will it match my other door hardware?
26D is satin chrome, the standard dull chrome used on most commercial openings, so the 28-10G24 will match satin chrome closers, exit devices, and hinges already in the building. Cal-Royal's AG05 storeroom lever is also offered in 26D if you need a different function on the same finish across a floor.
12) Is the B lever on this Sargent lock ADA compliant?
The B lever design is a lever handle rather than a knob, which is the ADA-compliant operating style because it needs no tight grasping or wrist twisting. That is why lever trim is specified on public-access doors. Knob trim, like Arrow's ball or tudor knob cylindrical locks, is generally restricted to non-public openings.
13) Does the Sargent 28-10G24 LB have a fire-rated counterpart if the opening needs a labeled lock?
If the door carries a fire label, choose a lock with a stated fire rating. The Falcon K101 Grade 1 passage lever is fire rated and covers doors 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CL3110 Grade 1 passage/closet lever is fire rated for 1-3/4 inch to 2 inch doors, and the Arrow MK02-TA privacy lock is fire rated for 1-3/4 inch to 2 inch doors. Match the function your opening calls for, since these are non-keyed or privacy rather than the Sargent's entrance/office.
14) Will a dummy lever or a lever trim work in place of the Sargent 28-10G24 LB?
No. The 28-10G24 LB is a complete keyed cylindrical lock with a latch. Parts like the BEST 9K Series 1DT single dummy trim and the Accentra 455LN Augusta single dummy lever are dummy function only - they mount a lever with no latch and no cylinder. The Corbin Russwin 585F715 is a Grade 1 lock lever component for ED8000 exit devices and CL3300 cylindrical locks, not a standalone lockset. Order those only when you are matching appearance or replacing a lever, not securing an opening.
15) Can I use a Kwikset or Baldwin lever instead of the Sargent 28-10G24 LB on a commercial corridor door?
Those are built for different openings. The Sargent 28-10G24 LB is Grade 1 for high-traffic commercial use. The Kwikset 200BRNL Breton is a Grade 3 passage lever for doors 1-3/8 inch to 1-3/4 inch, and the Baldwin Estate 5103 comes as passage, privacy, and left or right hand half dummy - the half dummies are handed, unlike the non-handed Sargent. For a commercial corridor, stay with a Grade 1 cylindrical lock such as the Falcon T101 heavy duty lever if a non-keyed opening, or match function with another Grade 1 keyed lock.
16) What is a lever equivalent to the Sargent 28-10G24 LB if the door currently has a knob lockset?
The Sargent 28-10G24 LB uses a B design lever, which gives ADA-compliant operation on an entrance/office door. Knob versions of comparable openings include the Arrow HK11-BB turn-pushbutton entrance lock with a ball knob and conventional cylinder for doors 1-3/8 inch to 1-3/4 inch, and the Arrow MK02-TA privacy lock with a Tudor knob. If you are upgrading from a knob to meet accessibility requirements, the lever body is the change you want.
17) For a multi-family unit where I need privacy rather than the keyed entrance function of the Sargent 28-10G24 LB, what do I order?
The 28-10G24 LB is an entrance/office lock with a keyed conventional cylinder, which is not a bed/bath privacy function. For privacy, the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch, the Kwikset 300BRNL Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors, and the Baldwin Estate 5103 is available in privacy function with the 5048 rose.
