Sargent 10XG53 LB 26D – Frequently Asked Questions

1) What does the corridor/dormitory function on the Sargent 10XG53 actually do?
Corridor function, also called dormitory function: the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. It is the function you want on a dorm room or a corridor door where staff need to key-control the outside and occupants need to always get out. The 10XG53 is a single-cylinder lock, so the keyed side is the outside only.
2) Will the Sargent 10XG53 fit a 1-3/4 inch commercial door?
Yes. The 10X Line cylindrical lock covers door thickness from 1-3/8 inches to 2 inches, so 1-3/4 inch (the standard commercial thickness) sits in the middle of the range. Thicker doors up to a full 2 inches work without a special kit, which is useful on older wood doors and on some fire-rated assemblies that run heavy.
3) Do I have to specify handing when ordering a Sargent 10XG53 lever lock?
No handing to specify. The 10XG53 is non-handed, so one part number covers left and right hand doors. For a property manager stocking spares across a building, that means a single lock on the shelf fits any opening in the fleet regardless of swing.
4) Can I get the Sargent 10XG53 keyed to my existing Sargent master key system?
Yes. The 10X lockbody takes every Sargent cylinder format, from fixed conventional to interchangeable core, and works with Sargent Key Systems. On the order you pick the cylinder (6-pin standard, 60 large format interchangeable core, or 70 small format interchangeable core), the keying (keyed different, keyed alike, or master keyed), and the keyway. Forty keyways are offered, LA being the standard, plus the CA through CR, HA through HK, LB through LL, R, RA through RL, S and U families. Give us the keyway and bitting your existing system runs on and the lock comes keyed into it.
5) Is the Sargent 10X lock tough enough for a high-abuse door like a school corridor or a public restroom?
This is the reason to buy this lock over a Grade 1 that just meets the minimum. It holds against more than 3,100 in-lb of locked lever torque (2.6 times the ANSI/BHMA requirement) and 1,600 lbs of offset lever pull (8 times the requirement), stays locked after more than 100 vertical impacts (20 times the ANSI/BHMA A156.2 requirement), and completed a UL Cycle Above and Beyond test at 20 million cycles. If your failure mode is people hanging on the lever or kicking it, that is the spec set that matters.
6) Is this lock approved for hurricane zones and Florida Building Code?
Yes. The 10X Line is windstorm certified for Florida Building Code compliance, with UL listings covering ASTM E330, ASTM E1996, ASTM E1886, and TAS 201, TAS 202 and TAS 203. For coastal and hurricane-prone work where the opening is part of the impact assembly, that is the certification list a spec writer is looking for.
7) Do I really need a Grade 1 lock like the Sargent 10X, or will a Grade 2 lever do?
It comes down to traffic and abuse. Grade 1 is the commercial heavy duty tier; Grade 2 is medium duty and Grade 3 is residential. On a low-traffic interior office or closet door, a Grade 2 lever such as the Hager 2510 passage or the Cal-Royal AG05 storeroom is the normal choice and both cover 1-3/8 inch to 1-3/4 inch or 2 inch doors. On a corridor, stairwell, dorm or restroom door that gets hit all day, the 10X is the one built for it, with 20 million cycles behind it. Do not spend Grade 1 money on a janitor closet, and do not put Grade 2 on a school corridor.
8) The opening needs a classroom lock instead of corridor function - what cylindrical lever should be ordered?
The Dexter C1000 Series classroom lock is a Grade 1 cylindrical lever with classroom function for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom security version adds keyed control of the inside lever. The Cal-Royal AG03 is a classroom lever in the AG Series with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset. The Sargent 10XG53 carries corridor/dormitory function, in which the outside lever is locked and released by key, so it is a different operating sequence than a classroom lock where the key locks and unlocks the outside lever from the corridor side.
9) Is the Corbin Russwin CL3100 a substitute for the Sargent 10XG53?
Not for the same opening. The Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock in the CL3100 Series, fire rated, for doors 1-3/4 inch to 2 inch, but it is passage/closet function with no cylinder. The Sargent 10XG53 is keyed with a single cylinder and carries corridor/dormitory function. They share the Grade 1 rating and the cylindrical lever format, so the CL3110 works where the door only needs to latch, while the 10XG53 covers the opening that has to be secured by key.
10) Can a Schlage keyed lock be swapped in when the building is on a Sargent key system?
Several peers are built around a Schlage C keyway, including the Cal-Royal AG00 entrance lever and the Cal-Royal AG03 classroom lever, both 6-pin Schlage C keyed different, and the Arrow MK33-BD-CS asylum lock with a conventional Schlage C cylinder. The Sargent 10XG53 is ordered with a 6-pin standard cylinder, the 60 large format interchangeable core or the 70 small format interchangeable core across the LA standard keyway and the C, H, L and R keyway families, and its lockbody supports all SARGENT Key Systems. Keep the keyway family consistent with the building master key system rather than mixing platforms on one floor.
11) What lever, rose and finish combinations can I get on the Sargent 10XG53?
Three lever designs (B, L and P), two rose shapes (G rose and L rose), and fourteen finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE and 10BL dark oxidized satin bronze variants, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, plus BSP black and WSP white suede powder coat. 26D satin chrome is the usual commercial default if you are matching existing institutional hardware.
12) Is there an antimicrobial option for a healthcare door?
Yes. Microshield antimicrobial coating is offered as an option on the 10X Line, for healthcare, food service and other environments where surface contamination control is part of the spec. Ask for it by name when you place the order, since it is an added coating rather than one of the standard finishes.
13) Can the Sargent 10X be electrified for access control or a wave-to-open opening?
Electromechanical functions are available in the 10X Line using EcoFlex technology, with up to 92 percent energy savings, and they cover wave to open and request to exit applications. Note that the 10XG53 itself is the mechanical corridor function lock; an electrified opening is a different configuration in the same line, and there is a separate 10X Line Electrified Bored Lock installation instruction for it.
14) What is the Grade 1 alternative to the Sargent 10X if I need a different lock function?
Function is fixed per model, so if corridor/dormitory is not what the opening needs, you change models. Within Grade 1 cylindrical levers, the Corbin Russwin CL3110 covers passage/closet and is fire rated, the Dexter C1000 Series covers classroom, classroom security, entry/office and asylum, and the Falcon K101 is a Grade 1 heavy duty passage lock with a 1-3/8 inch to 2-1/4 inch door thickness range. Falcon T101 is another Grade 1 heavy duty passage option. Pick the model whose function matches the door, then match backset and finish.
15) Can I convert an existing Sargent 10X to interchangeable core later without buying a new lock?
The lockbody is built to accept all cylinder formats, from fixed conventional through interchangeable core, so the chassis is not the limiting factor. What you specify at order time is which cylinder goes in: 6-pin standard, 60 Sargent large format interchangeable core, or 70 Sargent small format interchangeable core. For a facility that plans to move to SFIC across the building, ordering the 70 up front saves a cylinder swap later.
16) What is a lighter duty alternative to a Sargent 10XG53 for a low traffic interior door?
For interior openings that do not see corridor traffic, the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever for 1-3/8 inch to 2 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever over the same thickness range. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. The Sargent 10XG53 is a Grade 1 heavy duty lock built for high traffic, high abuse commercial environments and rated through 20 million cycles, so the Grade 2 options are a step down in cycle life, not a like-for-like swap.
17) Which lock should be used for a patient room or holding room instead of a corridor lock?
The Dexter C1000 Series asylum lock is a Grade 1 cylindrical lock with asylum/institution/utility function for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a heavy duty asylum cylindrical lock with a ball knob and a conventional cylinder in the Schlage C keyway. Asylum function keys both sides, so neither lever retracts the latch without a key. The Sargent 10XG53 carries corridor/dormitory function, where the inside lever always allows egress, which is why it is not the right choice for a room requiring key control from both sides.
18) What cylindrical lever matches the Sargent 10XG53 on the non-keyed doors of the same corridor?
To keep the same Grade 1 heavy duty level on doors that only need to latch, 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 Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. For a door leaf that carries trim only, the BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim cylindrical lever. The Sargent 10XG53 is non-handed as well, so a mixed run of keyed and non-keyed openings does not require handing to be specified.
19) If the opening needs an electrified lever instead of a mechanical corridor lock, what is available?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running 12VAC/DC for doors 1-3/4 inch to 2 inch, offered with the NZ lever and D rose, and in a keyed version. The Sargent 10XG53 is a mechanical cylindrical lock with corridor/dormitory function; the 10X Line does offer electromechanical functions with EcoFlex technology for access controlled openings including Wave to Open and Request to Exit, and those carry a separate electrified bored lock installation instruction.
20) Can a keypad lever be used in place of a keyed corridor lock to avoid issuing keys?
The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function, covering doors 1-1/8 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Both replace a key with a code at the door. The Sargent 10XG53 is keyed with a single cylinder and its lockbody accepts fixed, large format interchangeable and small format interchangeable cylinders across all SARGENT key systems, so it is the option when the opening has to sit inside an existing master key system rather than stand alone on a code.
21) Will a residential grade lever like the Kwikset Breton work on a commercial corridor door?
The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors and the Kwikset 300BRNL Breton is a Grade 3 privacy lever over the same thickness range; the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors. The Sargent 10XG53 is a Grade 1 heavy duty commercial cylindrical lock rated to 20 million cycles and tested against more than 3,100 in-lb of locked lever torque, which is the performance level a specification calling for Grade 1 corridor hardware is asking for.
22) What is the difference between the Sargent 10XG53 and an entry or office function lever like the Falcon B511?
The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function, and the Dexter C1000 entry/office is a Grade 1 clutching keyed lever for doors 1-3/8 inch to 1-3/4 inch. Entry/office function lets the occupant lock the outside lever from inside, typically with a button or turn. The Sargent 10XG53 uses corridor/dormitory function, so the outside lever state is set from the corridor by key rather than from inside the room, which is what facilities choose when they do not want occupants changing the locked state of the door.
23) I need a matching dummy lever on the inactive leaf, what goes with a heavy duty cylindrical lever set?
A dummy trim is a separate part, not a variant of the working lock. In Grade 1 heavy duty cylindrical trim, the BEST 9K Series 1DT single dummy and the Accentra 455LN Augusta are both single dummy levers at the same grade. The BEST 7KC Series 1DT is the medium duty Grade 2 equivalent if the inactive leaf is not taking abuse. Match the lever design and finish to the working lock so the pair reads the same.
24) Does a dummy or half dummy lever replace a corridor lockset on an inactive leaf?
No, a dummy lever has no latch at all - it is pull trim. The BEST 7KC Series 1DT is a Grade 2 medium duty non-keyed single dummy trim cylindrical lever, the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever in the 5400 Series, and the Callan Bentley is a Grade 2 dummy lever. Use one of those only on the inactive leaf where nothing latches, and keep the Sargent 10XG53, a keyed cylindrical lock with corridor/dormitory function, on the active leaf that has to secure the opening.
25) Is a decorative lever like the Baldwin Estate 5103 or a Deltana entry lever appropriate where a corridor lock is specified?
Those are different products for different openings. The Baldwin Estate 5103 comes in passage, privacy and half dummy versions with the 5048 rose, and the Deltana Manchester 6201, Morant 6411 and Linstead 6431 are entry levers for doors 1-3/8 inch to 2 inch. None of them carry corridor/dormitory function. The Sargent 10XG53 is a Grade 1 heavy duty keyed cylindrical lock with corridor/dormitory function, offered with B, L and P levers on a G or L rose and finishes from 26D satin chromium to 10B oil rubbed bronze, so the appearance can be matched without leaving the commercial function.
