Sargent 28-10G17-LL-26D – Frequently Asked Questions

1) What does the Utility/Asylum/Institutional function on the Sargent 28-10G17 actually do on the door?
It is the institutional function in Sargent's 10 Line cylindrical family, the one specified where staff need cylinder control from both sides of an opening rather than a free-turning inside lever. Think secure storage, mechanical and utility rooms, and patient or detention-adjacent spaces in healthcare and institutional buildings. If you want a lever that always releases from the inside, this is the wrong function and you should be looking at a storeroom or classroom lock instead.
2) Will the Sargent 10 Line lever lock fit a door already bored for a 2-3/8 inch backset?
Yes, with the right latch. The 28-10G17 ships on a 2-3/4 inch backset as standard, and Sargent offers optional 2-3/8 inch, 3-3/4 inch and 5 inch backset latches for retrofit openings. 2-3/8 and 2-3/4 are the two backsets you will meet on most existing doors, so specify the latch to match what is already bored rather than re-drilling the door.
3) Do I have to order the Sargent 28-10G17 handed for a left or right hand door?
No. The L lever is non-handed, so one part number covers left and right hand openings. That is worth knowing if you are stocking spares across a building, since you carry one lockset instead of two.
4) Will the Sargent 10 Line lockset work with my existing frame strike prep?
It uses the 808 ANSI strike, which is the standard commercial frame prep. If your frames were prepped for an ANSI strike on a previous commercial cylindrical lock, the new lock drops into the same cutout. Frames prepped for a small residential T-strike will need work.
5) Should I order the Sargent 28-10G17 with a conventional cylinder or LFIC?
Two cylinder builds are offered: conventional, and LFIC for large format interchangeable core. Choose conventional if the building is keyed on standard cylinders and rekeying is done by a locksmith. Choose LFIC if your facility already runs interchangeable cores and your maintenance staff rekeys by pulling and swapping cores with a control key. The lock is built on the LA keyway, and Sargent security key systems including Signature, Keso, BR-XC and XC are compatible for higher-security keying.
6) If the opening only needs a latch with no locking, what takes the place of the 28-10G17?
For a non-locking opening in the same Grade 1 heavy duty class, the Falcon K101 is a Grade 1 passage cylindrical lock with non-handed levers, a fire rating, and a 1-3/8 inch to 2-1/4 inch door thickness range; the Falcon T101 is also a Grade 1 heavy duty passage leverset. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever for 1-3/4 inch to 2 inch doors. The Sargent 28-10G17 is a utility/asylum/institutional function, which is a keyed-style institutional control rather than free passage.
7) Which levers look similar to the Sargent 28-10G17 but will not work as a substitute?
Dummy trims are the common mix-up: the BEST 9K Series 1DT is a Grade 1 non-keyed single dummy trim, the BEST 7KC 1DT is a Grade 2 medium duty dummy, and the Accentra 455LN Augusta is a Grade 1 single dummy. None of them latch or lock - they are pull trim only. The Sargent 28-10G17 is a full cylindrical lockset with an 808 ANSI strike and a utility/asylum/institutional function.
8) Is this Sargent lockset heavy duty enough for a high-traffic school or hospital corridor?
It is a Grade 1 heavy duty cylindrical lock tested past 4 million cycles, five times the ANSI 156.2 Series 4000 Grade 1 requirement, with a solid one-piece cast lever. Sargent also rates it to take more than twice the ANSI abusive locked-lever torque without allowing entry. That is the durability tier institutional and MRO specifiers write for corridor and utility doors.
9) Does the Sargent L lever meet ADA requirements for accessible openings?
The lever trim on the 10 Line is ADA compliant, and Sargent offers six ADA lever styles in the family if the L lever does not match the design elsewhere in the building. A lever operates without tight grasping or wrist twisting, which is why it is specified over a knob on accessible openings.
10) What is a Grade 1 alternative to the Sargent 28-10G17 asylum lock from another brand?
The Dexter C1000 Series asylum lock (F87 function) is the closest cross-brand match we carry: Grade 1, same asylum/institution/utility function, and it lists a 1-3/8 to 2 inch door thickness range. If you are working to a lighter grade, the Arrow MK33-BD-CS is a heavy duty Grade 2 asylum lock, but it uses a ball knob rather than a lever, so it is not a like-for-like swap on an opening that needs lever trim.
11) Is there a lower-grade asylum function lock if Grade 1 is more than the opening needs?
The Arrow MK33-BD-CS is an Asylum/Institution/Utility cylindrical lock rated Grade 2 with a heavy duty level, using a ball knob rather than a lever and a conventional cylinder in a Schlage C keyway. The Sargent 28-10G17 is Grade 1 with a lever handle and an LA keyway, so the Arrow is a knob-trim option on a different key system.
12) What should I use on a classroom door instead of the Sargent 28-10G17?
The Dexter C1000 Series classroom lock (DEX-C1000-CLRM) is a Grade 1 keyed clutching cylindrical lever for 1-3/8 inch to 1-3/4 inch doors, and the C1000 Classroom Security version (DEX-C1000-CSEC) adds inside-key locking of the outside lever. Cal-Royal AG03 is a Grade 2 classroom lever on a 6-pin Schlage C keyway with a 2-3/4 inch backset, the same backset the Sargent 28-10G17 uses.
13) I need a storeroom function lever for a back-of-house door, not an institutional lock. What fits?
The Cal-Royal AG05 is a Grade 2 storeroom leverset 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 the Withnell lever for 1-3/8 inch to 2 inch doors. Both keep the outside lever locked at all times; the Sargent 28-10G17 carries the utility/asylum/institutional function, which is keyed on both sides.
14) Is there an electrified cylindrical lever alternative if the door needs to tie into access control?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for doors 1-3/4 inch to 2 inch thick, offered with an NZ lever and D rose. The Sargent 28-10G17 is a mechanical Grade 1 cylindrical lockset with no electrical connection.
15) Can I use a Grade 2 or Grade 3 residential-style lever on a high-traffic institutional door instead?
Those are built for a lighter cycle load. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Callan Asheville is a Grade 3 passage leverset. The Sargent 28-10G17 is a Grade 1 heavy duty commercial lockset with solid one-piece cast lever construction, tested past 4 million cycles.
16) What finish does the Sargent 28-10G17 come in, and will it match other hardware in the building?
It is supplied in 26D, satin chromium plated over nickel, which is the standard satin chrome look on most commercial openings and matches typical satin stainless closers, hinges and exit devices. The 10 Line family is produced in 11 architectural grade finishes if you are matching a different spec across a facility.
17) Can I use the Sargent 10 Line lockset on apartment or residential interior doors?
You can, but it is built for commercial service and priced and specified that way. For residential interior doors, the Grade 2 and Grade 3 leversets we carry, such as the Hager 2510 passage lever for 1-3/8 to 2 inch doors or the Kwikset 200BRNL Breton passage lever for 1-3/8 to 1-3/4 inch doors, are the usual choice. Where a multi-tenant building has abuse-prone common area and utility doors, the Sargent is the one that survives.
