Sargent 28-10U65 LL 26D – Frequently Asked Questions

1) Will the Sargent 28-10U65 privacy lock fit a 1-3/4 inch commercial door?
Yes. The Sargent 10 Line 28-10U65 privacy lock covers doors from 1-3/4 inches up to 2 inches thick, so a standard commercial 1-3/4 inch door is right in range. Below that, on an older 1-3/8 inch interior door, it is the wrong lock. The other prep number to check is the stile: the lock needs at least 4-1/2 inches of stile width, which rules out most narrow stile aluminum entrances.
2) What backset does the Sargent 10 Line 28-10U65 need, and can it go into an existing 2-3/8 inch bore?
Standard on the 28-10U65 is a 2-3/4 inch backset, which is what most commercial doors are prepped for. Sargent also builds the 10 Line in 2-3/8 inch, 3-3/4 inch, and 5 inch backsets, so an existing 2-3/8 inch residential-style prep can be matched by specifying that backset on the order rather than moving the cross bore. The 3-3/4 and 5 inch options exist for wide stile and glass-adjacent openings where the lever has to sit farther off the edge.
3) Can a privacy bathroom lock be used on a fire rated restroom door?
The Sargent 10 Line privacy lock is UL-cUL listed for 3 hour fire doors, so it can go on a rated restroom opening. It is also listed for windstorm applications. Privacy function means it locks from inside with no key cylinder, which is standard practice for a single-occupancy restroom on a rated door.
4) Is the Sargent 28-10U65 keyed, and how does anyone get in if someone is locked in the bathroom?
Privacy bathroom function, which means no key cylinder. It locks from the inside only. There is no keyway to pin, no keyway family to match to the rest of the building. If you need a lock a key can override, the privacy function is the wrong choice and you want a keyed function from the same 10 Line family instead.
5) Is a Grade 1 lock worth it on a restroom door, or will Grade 2 do?
It comes down to traffic. The Sargent 10 Line is ANSI/BHMA Grade 1 with 9.6 million cycles of testing and torque resistance 1.5 times the standard, which is what a public restroom in an office, school, or hospital actually sees. For a lower-traffic bath or bedroom door, a Grade 2 privacy set does the job. ZenSupply carries the Hager 2540 with the Withnell lever as a Grade 2 cylindrical privacy option, and the Kwikset 300BRNL Breton as a Grade 3 residential privacy lever.
6) The restroom door does not need to lock at all - what do I use instead of a privacy lock?
For an opening that only needs latching with no locking, the Grade 1 passage locks are the substitute. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever lock, fire rated, for 1-3/4 inch to 2 inch doors, which matches the door range the Sargent 28-10U65 covers. The Falcon K101 is a Grade 1 heavy duty passage lock, fire rated, with non-handed levers and a wider 1-3/8 inch to 2-1/4 inch door range. Both omit the inside thumbturn and emergency release that make the Sargent 28-10U65 a privacy bathroom lock.
7) What is the closest Grade 1 privacy cylindrical lock to the Sargent 28-10U65 if I need a knob instead of a lever?
The Arrow MK02-TA covers the same privacy/bed/bath function at Grade 1 with a Tudor knob instead of a lever, is non-keyed like the Sargent, carries a fire rating, and fits the same 1-3/4 inch to 2 inch door thickness range the Sargent 28-10U65 accommodates. The Sargent 28-10U65 uses the L lever, which is the trim style most commercial restroom specs call for on ADA-governed openings; the Arrow is the knob-trim equivalent when the opening does not require lever operation.
8) Is there a lighter-duty privacy lever lock for restrooms that do not see commercial traffic?
The Hager 2540 privacy cylindrical lock with the Withnell lever is Grade 2 and fits doors from 1-3/8 inch to 2 inch, so it takes in thinner doors than the Sargent 28-10U65, which starts at 1-3/4 inch. For lighter residential-style openings, the Kwikset 300BRNL Breton privacy lever set is Grade 3 and fits 1-3/8 inch to 1-3/4 inch doors. The Sargent 28-10U65 is the Grade 1, heavy duty option rated at 9.6 million cycles and UL-cUL listed for 3-hour fire doors, which is what a high-traffic public restroom or a rated opening calls for.
9) I need staff to be able to lock the restroom from the outside with a key - is the Sargent 28-10U65 the right lock?
No. The Sargent 28-10U65 is a non-keyed privacy bathroom lock, so there is no outside cylinder. For a keyed function on the same kind of cylindrical prep, the Hager 2580 is a Grade 2 storeroom lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. Storeroom function keeps the outside lever locked at all times and releases only by key.
10) What is the difference between a privacy lock and an asylum function lock for a behavioral health restroom?
The Sargent 28-10U65 is a privacy bathroom lock: it locks from inside the room and is non-keyed. An asylum or institutional function locks and unlocks by key from both sides with no inside thumbturn, so an occupant cannot secure themselves in. The Dexter C1000 is a Grade 1 asylum (F87) cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob and a conventional cylinder in the Schlage C keyway. Behavioral health and detention specs normally call for the asylum function rather than privacy.
11) The restroom door is only 1-3/8 inch thick - what privacy or passage lever fits it?
The Sargent 28-10U65 starts at 1-3/4 inch. For a 1-3/8 inch door, the Hager 2540 privacy lock with the Withnell lever is Grade 2 and covers 1-3/8 inch to 2 inch, and the Hager 2510 is the Grade 2 Withnell passage lever over the same 1-3/8 inch to 2 inch range if no locking is needed. The Falcon K101 Grade 1 passage lock also reaches down to 1-3/8 inch and up to 2-1/4 inch, with a fire rating and non-handed levers.
12) Do I have to specify handing when I order a Sargent 28-10U65 lever lock?
No handing to call out. The L lever on the 28-10U65 is non-handed, so one part number works on a left or right hand door swinging either way. For a property manager stocking spares across a building, that means one SKU on the shelf instead of two.
13) I want a privacy function but with a knob instead of a lever. What is the equivalent?
The lever is not interchangeable on a bored lock, so a knob means a different part. The Arrow MK02-TA is a privacy bed and bath cylindrical lock with a Tudor knob, non-keyed, fire rated, and it covers the same 1-3/4 to 2 inch door thickness range as the Sargent. Worth noting that lever hardware is what ADA-driven specs generally call for on commercial restrooms, so a knob is usually a residential or back-of-house choice.
14) Can I order a dummy lever to match a Sargent 28-10U65 privacy lock on an inactive leaf?
A dummy trim is a different part, not a substitute: it mounts a fixed lever with no latch. The BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim cylindrical lever lock, and the BEST 7KC Series 1DT is the Grade 2 medium duty single dummy trim. The Accentra 455LN Augusta is a Grade 1 heavy duty single dummy in the 5400 Series. Use one of those on the inactive leaf and keep the Sargent 28-10U65 on the leaf that actually latches and locks.
15) Does a keypad lever set do the same job as a privacy bathroom lock?
No. 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 control who gets in by code; neither gives an occupant the inside thumbturn and outside emergency release that a bathroom privacy function provides. The Sargent 28-10U65 is a non-electronic privacy lock for 1-3/4 inch to 2 inch doors. Code-controlled staff restrooms sometimes use both concepts on different openings, but they are not interchangeable on the same door.
16) Is there a decorative privacy lever for an executive or hospitality restroom instead of a commercial cylindrical lock?
The Baldwin Estate 5103 privacy lever with the 5048 rose gives the same privacy/bed/bath function in a decorative Estate-line trim, and the matching 5103 passage lever and left- and right-hand half dummy levers let one design run across every door in the suite. The Sargent 28-10U65 is the heavy duty commercial route: Grade 1, 9.6 million cycles, and UL-cUL listed for 3-hour fire doors, which is what a rated or high-traffic public restroom opening needs.
17) What is the Sargent 10 Line privacy lock made of, and will it hold up in a humid restroom?
Roses are wrought brass and bronze, the latch is stainless steel, and the cylindrical housing is steel. That combination is what gives it corrosion resistance in a wet restroom environment, and the heavy duty rating is the reason it gets specified in commercial washrooms rather than a residential set.
18) What finish does the Sargent 28-10U65 come in, and will it match the rest of my door hardware?
26D, satin chromium plated over nickel. That is the brushed chrome look that dominates commercial openings, so it lines up with the satin chrome closers, hinges, and push plates already on most office, school, and healthcare doors.
19) Does the Sargent 28-10U65 need power or wiring run to the door?
No. It is a purely mechanical bored lock, no wiring, no transfer hinge, no power supply. If the job actually calls for an electrified cylindrical lever on the same kind of opening, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever running 12V AC/DC for 1-3/4 to 2 inch doors.
