Sargent 28-10G05-LL-26D – Frequently Asked Questions

1) Is the Sargent 10G05 handed, or do I have to specify left or right?
No handing to specify. The 10G05 is a non-handed cylindrical lockset, and the B, L, J and P levers are themselves non-handed, so one part covers either swing. That is what makes it practical to stock a single lock for a whole building.
2) Will the Sargent 28-10G05 work with my existing Sargent LA key system?
Yes. The 10G05 is furnished with the Sargent LA keyway, so it keys into an existing LA master key system without changing cylinders. If your building runs a different Sargent section, order the matching keyway rather than assuming LA drops in.
3) Should I order the conventional cylinder or the interchangeable core version?
Three cylinder choices on the 10G05: conventional, LFIC (large format interchangeable core) and SFIC (small format interchangeable core). Pick conventional if the site has no core program. Pick LFIC or SFIC when the facility rekeys itself, since a core can be pulled with a control key and swapped in seconds instead of pinning a cylinder. Match whichever format the rest of the building already uses.
4) Is this Sargent lockset heavy duty enough for a high-traffic school or hospital corridor?
It is built for exactly that. The 10 Line carries Grade 1 certification to ANSI A156.2 Series 4000 and is tested past 4 million cycles, five times the Grade 1 requirement, and it withstands more than twice the standard abusive locked-lever torque without allowing entry. Sargent lists education, healthcare, government and industrial openings among its applications.
5) I need a Grade 1 lever that matches the Sargent 10 Line but for a door that should stay unlocked - what do I order?
The Sargent 28-10G05 is an entrance function lock, so it latches and locks. For a door that only needs latching, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, for 1-3/8 inch to 2-1/4 inch doors, and the Falcon T101 is a Grade 1 heavy duty passage lever. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 inch to 2 inch doors, and the Dexter C1000 passage is a Grade 1 clutching non-keyed lever for 1-3/8 inch to 1-3/4 inch doors.
6) What is a lighter-duty alternative to the Sargent 28-10G05 entry lever for a moderate-traffic office door?
The Sargent 28-10G05 is a Grade 1 heavy duty cylindrical entrance lever. If the opening does not need Grade 1, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever lock with the same Entry/Office function. The Hager 2525 is another Grade 2 commercial cylindrical entry lock with a lever handle, rated for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG00 entrance lever is a Grade 2 unit with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset. Note the Sargent uses a 2-3/4 inch backset, so a 2-3/8 inch prep is not a direct swap.
7) The door needs to stay locked from the outside at all times - is the Sargent 28-10G05 the right function?
No. The 28-10G05 is an entrance/office function lever, where the outside can be left unlocked or locked by the occupant. For a door that must always require a key from outside while free egress is maintained, look at a storeroom function lever such as the Cal-Royal AG05, a Grade 2 storeroom lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, or the Hager 2580 Grade 2 storeroom cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors.
8) We use Schlage C keyed systems - can we key the Sargent 28-10G05 into them, or should we pick a different lever?
The Sargent 10 Line lever is built around the LA keyway, which is Sargent's own profile, so it does not key into a Schlage C system. If your facility is standardized on Schlage C, the Cal-Royal AG00 entrance lever is a Grade 2 unit supplied with a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock also uses a conventional Schlage C keyway cylinder.
9) What does the entrance/office function actually do on this Sargent lever lock?
Entrance/office function: the outside lever is locked or unlocked by a pushbutton or key, the key retracts the latch from outside when locked, and the inside lever always retracts the latch for free egress. It is the normal choice for tenant suite doors and private offices where staff want to lock up on the way out without a key.
10) Is the lever on the Sargent 10G05 ADA compliant?
Yes, the 10 Line offers six ADA lever styles, and the lever design conforms to national and state fire and handicapped requirements. The L lever is the style supplied in satin chromium (26D) and satin bronze (10) here.
11) Can I use a cheaper Grade 2 entry lever instead of the Sargent 10 Line?
You can, on lower-traffic openings. The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever in the same entrance/office function, and the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 to 2 inch doors. The trade-off is cycle life and abuse resistance: the Sargent 10 Line is heavy duty Grade 1 tested past 4 million cycles. For a storage room or an interior suite door a Grade 2 is usually fine; for a main tenant entrance in a busy building it is not.
12) Can I get vandal-resistant or tamper-proof trim on the Sargent 10 Line lever?
Yes. Optional free wheeling vandal-resistant trim is available, along with Torx and spanner screws so the trim cannot be pulled with a standard driver. For higher security key control, the 10 Line also supports Signature Keso, BR-XC and XC key systems. These are ordering options, so they have to be called out when the lock is specified.
13) Does this Sargent lockset come keyed, or do I have to key it myself?
The 10G05 as configured ships non-keyed, meaning cylinders are not pre-keyed to a system. A locksmith or the facility pins it to the site's LA keyway, or, if you choose the LFIC or SFIC option, you simply install your own cores.
14) Is a classroom lock a substitute for the Sargent 28-10G05 entry lever?
No, they are different functions. The 28-10G05 is entrance/office. A classroom function lever is keyed from the outside only with no inside locking - the Dexter C1000 classroom is a Grade 1 clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway keyed different on a 2-3/4 inch backset. Dexter also offers a C1000 Classroom Security version in Grade 1 with keyed control of both sides.
15) What do I order to match the Sargent 28-10G05 on a door that only needs a fixed pull with no latch?
A dummy trim, not a lockset. The 28-10G05 is a working cylindrical entrance lever; for an inactive leaf or closet face, the BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed cylindrical lever dummy, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever. A medium duty option is the BEST 7KC Series single dummy trim in Grade 2.
16) Can I use a residential entry leverset instead of the Sargent 28-10G05 in an apartment building corridor?
They are not equivalent in duty rating. The Sargent 28-10G05 is a commercial Grade 1 heavy duty lever. Residential-grade entry levers such as the Cal-Royal AUS00 entrance/office lever and the Callan Artino entrance leverset are Grade 3, and the Callan Bennett is a Grade 3 entrance leverset with a deadbolt combo. For unit doors where a Grade 3 set is acceptable those work; for high-cycle common-area openings the Grade 1 Sargent is the heavier specification.
17) We want keypad access instead of a keyed entry lever - what replaces the Sargent 28-10G05?
The 28-10G05 is a keyed-cylinder lever using the LA keyway. For code-based access on the same style of opening, the Delaney LP250 is a Grade 2 electronic keypad leverlock, 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 Emtek offers a Classic keypad leverset. Note the Lockey is passage function, so it does not secure the opening the way the Sargent entrance lock does.
18) Is there an electrified Grade 1 cylindrical lever comparable to the Sargent 28-10G05 for an access control opening?
The 28-10G05 is a mechanical entrance lever with no electrical option in its configuration. For access control tie-in, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC for 1-3/4 inch to 2 inch doors, offered with an NZ lever and D rose.
19) For a restroom or bedroom door, is the Sargent 28-10G05 the right lock?
No - the 28-10G05 is an entrance/office function that takes a key from outside. A privacy function is the correct choice there: the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed and fire rated, and the Baldwin Estate 5103 is offered in a privacy lever with the 5048 rose.
20) What is the difference between the Sargent 28-10G05 and the Arrow HK11-BB entrance lock?
Both are entrance function bored locks with a conventional cylinder, but the trim and duty differ. The Sargent 28-10G05 is a Grade 1 heavy duty lever on a 2-3/4 inch backset with the LA keyway. The Arrow HK11-BB is a Grade 2 turn-pushbutton entrance cylindrical lock with a ball knob rather than a lever, fitting 1-3/8 inch to 1-3/4 inch doors. If ADA lever operation is required at the opening, the knob trim is not an equivalent.
21) Are there Grade 1 passage levers that share the Sargent 28-10G05's non-handed installation?
Yes. The Sargent 10 Line is non-handed, which lets one part number cover either swing. The Falcon K101 is a Grade 1 passage cylindrical lock specified with non-handed levers, and the Falcon B101 is a Grade 2 medium duty passage lever also built non-handed. Both simplify stocking the same way the Sargent does, though neither is a keyed entrance function.
22) Is the Corbin Russwin 585F715 lever a replacement trim for the Sargent 28-10G05?
No. The 585F715 is a Grade 1 lock lever component for Corbin Russwin ED8000 pushpad exit devices and the CL3300 cylindrical lock series, sized for 1-3/4 inch to 2 inch doors - it is trim hardware, not a complete lockset. The Sargent 28-10G05 is a full cylindrical entrance lockset that comes with an 808 ANSI strike.
