Sargent 10XU15 LB 26D – Frequently Asked Questions

1) Will the Sargent 10XU15 passage lever fit a 1-3/8 inch door, or does it need a full 1-3/4 inch commercial door?
Door thickness range on the 10X Line passage lock runs 1-3/8 inches to 2 inches, so it covers both the older 1-3/8 interior doors and standard 1-3/4 commercial doors without any special order. That range also means it drops onto thicker 2 inch doors that stop a lot of Grade 2 leversets. No thickness suffix to specify, the same lock body handles the span.
2) Is the Sargent 10XU15 handed? I need to order for doors swinging both directions.
Non-handed. The 10XU15 passage lever installs on a left or right hand door with no field reversing and no separate part number, so a property manager ordering for a whole floor can buy one configuration and not sort by swing.
3) Does a passage lock lock at all? I need something for a corridor door that latches but never locks.
That is exactly what the 10XU15 is. It is a passage function lock, non-keyed, with no cylinder and no button, so the lever always retracts the latch from both sides. It holds the door closed against a strike, it never secures it. For a door that needs to lock you want a different function in the same 10X Line: storeroom, classroom, office, or privacy. Ordering passage for a door someone expects to lock is the most common mistake on this part.
4) Is the Sargent 10XU15 fire rated for a labeled corridor door?
The 10X Line passage lock carries UL-cUL fire ratings up to 3 hours, along with Florida Building Code approval and ADA compliance. It is an ANSI/BHMA F75 passage function. On a labeled opening, the lock is only part of the assembly, the frame, door, and closer all have to carry their own listings for the door to hold its label.
5) Is a dummy lever the same as a Sargent 10XU15 passage lock?
No. The Sargent 10XU15 is a cylindrical passage lock, so it carries a working latch that the lever retracts. A dummy trim is fixed and has no latch at all - the BEST 9K Series 1DT is a Grade 1 non-keyed heavy duty single dummy trim cylindrical lever, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever from the 5400 Series. Order dummy trim only for an inactive leaf or a door held by a ball catch; a latched door needs the passage lock.
6) Which Grade 1 passage lever covers doors thicker than 2 inches?
The Falcon K101 is a Grade 1 heavy duty non-handed passage cylindrical lock, fire rated, in the K Series, with a door thickness range of 1-3/8 inch to 2-1/4 inch. The Sargent 10XU15 passage lock is rated for 1-3/8 inch to 2 inch doors. For a thick leaf beyond 2 inches, the K101 is the one that reaches it.
7) What should I order if the door needs to lock instead of a passage function?
The Sargent 10XU15 is non-keyed with a passage function, so the lever always retracts the latch and the door never secures. For a keyed opening 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, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Dexter C1000 entry/office is a Grade 1 clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors. For a bed or bath door, the Hager 2540 privacy lock with Withnell lever covers 1-3/8 inch to 2 inch.
8) What do I order for an electrified opening rather than the mechanical Sargent 10X passage lock?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running 12VAC/DC, available with the NZ lever and D rose, for 1-3/4 inch to 2 inch doors. The Sargent 10XU15 is a mechanical passage lock; the 10X Line itself carries electromechanical functions with EcoFlex technology for Wave to Open, Request to Exit and Door Position Switch applications, so an access-controlled door stays within the same line rather than needing the passage unit.
9) Can I match a Sargent 10X passage lever to the keyed locks already on my other doors?
Trim matches across the 10X Line: three lever designs (B, L, and P) and two rose styles (G and L), in 14 finishes running from 03 bright brass and 04 satin brass through 10B oil rubbed bronze, 26D satin chrome, and BSP black or WSP white suede powder coat. Spec the same lever, rose, and finish code as your keyed 10X openings and the passage doors read identically down the corridor. The lock itself carries no cylinder, since it is non-keyed, so there is nothing to key alike.
10) Is a Grade 1 passage lock worth it over a Grade 2 for a school corridor, or am I paying for a spec I do not need?
On a high traffic opening the difference shows up in abuse, not in normal use. The 10XU15 is Grade 1 heavy duty and was run through UL's Cycle Above and Beyond test at 20 million cycles, holds against more than 3,100 in-lb of locked lever torque, and takes 1,600 lbs of offset lever pull while still restricting entry. It also resists more than 100 vertical impacts, and the push/turn button design keeps door stops and walls from breaking the trim. If the door sees students, carts, or public traffic, that is the case. A back office closet does not need it, and a Grade 2 passage lever like the Falcon B101 or the Hager 2510 covers that.
11) What else could I buy instead of the Sargent 10XU15 if I want a Grade 1 heavy duty passage lever?
Three real equivalents sit alongside it. The Falcon K101 is Grade 1 heavy duty passage, fire rated, and covers 1-3/8 to 2-1/4 inch doors, so it reaches thicker doors than the Sargent's 1-3/8 to 2 inch span. The Falcon T101 is Grade 1 heavy duty passage as well. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, but limited to 1-3/4 to 2 inch doors, which rules it out on a 1-3/8 inch door where the Sargent works. Design Hardware X75 is a Grade 1 flat lever passage option for 1-3/4 inch doors.
12) Can a Sargent 10X passage lock be converted to a keyed or electrified function later?
The 10X lockbody accepts all cylinder formats, fixed through interchangeable core, and works with every SARGENT key system, so the platform carries across the line. The 10XU15 itself is built as a non-keyed passage lock and has no cylinder in it. If a door might need to lock down the road, order the keyed function up front rather than planning a conversion. On the electrified side, the 10X Line runs EcoFlex, up to 92 percent energy savings on electromechanical functions, and supports Wave to Open, Request to Exit, and Door Position Switch, but those are electrified 10X models, not this passage lock.
13) Is there a Grade 2 passage lever for lower traffic doors instead of the Sargent 10X passage lock?
Several. The Falcon B101 is a Grade 2 medium duty non-handed cylindrical passage lever in the B Series. The Accentra 5301LN Augusta is a Grade 2 cylindrical lever in passage/closet function from the 5300 Series, and the Accentra 4601LN is a Grade 2 passage lever with Augusta trim from the 4600 Series. The Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell design covering 1-3/8 inch to 2 inch doors. The Sargent 10XU15 is Grade 1 heavy duty, which is the specification for high traffic openings; the Grade 2 units suit interior doors that see lighter use.
14) Can I use a residential passage lever on a commercial corridor door instead of the Sargent 10X?
The Kwikset 200BRNL Breton passage lever is 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 10XU15 is a Grade 1 heavy duty commercial lock tested to 20 million cycles and rated ANSI/BHMA F75. For a corridor or any opening with commercial traffic the Grade 1 unit is the one written into the spec; the Grade 3 levers are built for residential interior doors.
15) Is there a keypad lever that replaces a passage lock where the door now needs code access?
The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function, fitting doors from 1-1/8 inch to 2 inch. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The Sargent 10XU15 is a non-keyed passage lock with no access control of any kind, so if the door has to restrict who comes through, the keypad units are the change; a keypad unit and a passage lock are not interchangeable in the same opening.
16) Is a knob lockset an acceptable substitute for a Grade 1 lever passage lock?
Not where lever operation is required. The Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob and the Arrow HK11-BB is an entrance cylindrical lock with a ball knob for 1-3/8 inch to 1-3/4 inch doors - both are knob trim, and both are also different functions from passage. The Sargent 10XU15 is a lever handle lock and the 10X Line is stated as ADA compliant, which is the reason a lever gets specified on accessible openings in the first place.
17) For a patient room or utility door, what replaces a passage lock?
The Dexter C1000 Series asylum lock is a Grade 1 cylindrical lock in the F87 asylum function for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum, institution and utility cylindrical lock with a ball knob and a conventional cylinder in the Schlage C keyway. The Sargent 10XU15 is a non-keyed passage lock, so it has no cylinder and cannot deliver key control from either side; asylum openings need the keyed unit.
18) What is the Grade 1 classroom equivalent when a passage lock will not hold the door secure?
The Dexter C1000 Series classroom lever is a Grade 1 clutching keyed cylindrical lock for 1-3/8 inch to 1-3/4 inch doors, and the C1000 classroom security version adds key control from both sides in the same Grade 1 clutching keyed construction and thickness range. The Sargent 10XU15 is the Grade 1 passage function, correct for corridors and closets that never need to lock, and both classroom units are keyed alternatives on the same class of door.
19) Can I use a Sargent 10XU15 on an apartment interior door, or is it overkill for residential?
It is a commercial lock, built and graded for commercial traffic, and it will work fine on an apartment hall or closet door. Whether it is the right spend depends on the door. In a multi-tenant building where a maintenance team wants one lever family across common areas and units, standardizing on 10X makes sense. For an in-unit closet door with light traffic, a Grade 3 passage lever like the Kwikset 200BRNL Breton, which fits 1-3/8 to 1-3/4 inch doors, or a Grade 2 Bravura Atlanta passage leverset covers it.
20) Which passage lever matches a decorative interior door rather than a commercial corridor?
The Baldwin Estate 5103 passage lever with the 5048 rose is a decorative passage unit, and the same 5103 trim is offered in privacy and in left hand and right hand half dummy so a suite of doors can match. Bravura also lists Grade 2 passage leversets in the Atlanta, Orlando and Miramar round trim styles and the Tampa square trim style. The Sargent 10XU15 is a commercial Grade 1 lock offered with B, L and P levers on a G or L rose in finishes from bright brass through black and white suede powder coat.
