Sargent 10XG71-LL-26D-LC – Frequently Asked Questions

1) Will the Sargent 10XG71 fail secure cylindrical lock fit a 1-3/4 inch door?
Yes. The 10XG71 covers doors from 1-3/8 to 2 inches thick, so a standard 1-3/4 inch commercial door is in the middle of the range, and the same lock carries over to a 1-3/8 inch older interior door or a 2 inch heavy door without a different part number.
2) What does fail secure mean on an electrified Sargent 10XG71 lock, and is it the right choice for my door?
Fail secure means the outside lever stays locked when power drops. Access control energizes the lock to let someone in; kill the power and the door is secured from outside, while free egress from the inside is unaffected. That is what you want on a stairwell, a server room, a supply room, or any exterior opening. If your local code or life-safety plan requires the door to release on power loss (some fire-alarm-tied openings do), you need a fail safe lock instead, such as the Corbin Russwin CL33903 electrified cylindrical lever in 12V AC/DC.
3) Does the Sargent 10XG71 lock come with a cylinder?
No. The 10XG71 ships less cylinder, so you supply the cylinder and keying separately. The lockbody takes any cylinder format Sargent offers, fixed or interchangeable core, and works with all SARGENT key systems, so it drops into an existing Sargent master key plan without changing the lockset. If you are standardizing on a different keyway, order the cylinder to match that system before install.
4) What is the closest Grade 1 electrified cylindrical lever lock to the Sargent 10XG71-LC if a different manufacturer is specified on the job?
The Corbin Russwin CL33903 is the nearest Grade 1 electrified cylindrical lever lock in the set. It is listed as a fail safe lever running 12VAC/DC, where the Sargent 10XG71-LC is a fail secure cylindrical lock. That is the decisive difference for a security integrator: fail secure holds the outside lever locked when power drops, fail safe releases it. Confirm which behavior the door's egress and access control sequence calls for before swapping, since the two are not interchangeable on the same opening. Door thickness on the CL33903 is 1-3/4 inch to 2 inch, while the Sargent 10X body covers 1-3/8 inch to 2 inch.
5) Which Grade 1 lever lock should be used instead of the Sargent 10XG71 on a door with no electrified access control?
If the opening has no power and no card reader, a mechanical Grade 1 lever is the match rather than an electrified body. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors. The Falcon T101 is a Grade 1 heavy duty passage lever as well. Both are passage function, so they latch without locking; for a keyed mechanical opening the Dexter C1000 Entry/Office is Grade 1 and keyed with a clutching lever for 1-3/8 inch to 1-3/4 inch doors. The Sargent 10XG71 is a keyed fail secure cylindrical lock and only earns its keep where an access control circuit is actually driving it.
6) What is the right lock for a classroom or a classroom security opening rather than the Sargent 10XG71 fail secure?
Classroom and classroom security are distinct mechanical functions and the fail secure electrified body does not provide them. The Dexter C1000 Classroom is a Grade 1 clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Classroom Security is the Grade 1 clutching keyed version with classroom security function over the same thickness range. The Cal-Royal AG03 classroom lever is offered with a 6-pin Schlage C keyway keyed different on a 2-3/4 inch backset. Pick the classroom function when a teacher needs to lock or unlock the outside lever by key from a specific side; the Sargent 10XG71 answers the opening whose lock state is driven by a power supply and a credential reader instead.
7) Does a Schlage cylinder adapter kit let a Sargent 10XG71 accept an existing Schlage keyway?
No. The Accentra 107S is a Schlage cylinder adapter kit made for Yale hardware, not for the Sargent 10X body. The 10XG71 lockbody supports all cylinder formats from fixed to interchangeable core and integrates with SARGENT key systems, and it ships less cylinder so the cylinder is ordered to the facility's existing keying. A locksmith consolidating a building already on a Schlage C keyway should note that the Cal-Royal AG00 entrance lever and AG03 classroom lever are supplied with 6-pin Schlage C keyway cylinders keyed different, and the Arrow MK33 uses a conventional Schlage C keyway cylinder.
8) Do I have to specify handing for a Sargent 10X Line lever lock?
No handing to specify. The 10XG71 is non-handed, so one part covers left and right hand openings and you can stock a single lock across a building instead of splitting inventory. That also means a lock pulled off one door can go back on a door of opposite hand.
9) What is the difference between a Grade 1 and a Grade 2 cylindrical lever lock for a commercial building?
Grade is the ANSI/BHMA durability and strength tier, and it decides where the lock belongs. The Sargent 10X Line is Grade 1 heavy duty, tested to 20 million cycles, and it is the tier for main entrances, corridors, classrooms, and anything the public touches all day. Grade 2 is medium duty and suits interior offices and lower-traffic openings, for example the Falcon B511CP6D entry/office lever or the Hager 2580 storeroom lever. Grade 3 is residential-level, like the Cal-Royal AUS00 entrance lever. Buying down a grade on a high-traffic door is the usual reason a lockset gets replaced early.
10) I need a Grade 1 electrified cylindrical lever lock but not Sargent keying. What else is there?
The closest cross-brand equivalent carried is the Corbin Russwin CL33903, a Grade 1 electrified cylindrical lever in 12V AC/DC for 1-3/4 to 2 inch doors. Note the difference in function: the CL33903 is fail safe, unlocking on power loss, while the Sargent 10XG71 is fail secure and stays locked. They are not interchangeable on an opening where the life-safety plan specifies one behaviour. The Corbin also starts at 1-3/4 inch thickness, so on a 1-3/8 inch door the Sargent is the one that fits.
11) I need a matching non-keyed passage or dummy lever to go with a keyed Grade 1 cylindrical lock. What works?
The 10XG71 is a keyed single cylinder lock, so for the closets, corridors, and inactive leaves on the same job you need a separate non-keyed set. Grade 1 options carried include the Falcon K101 passage lever, which is fire rated and covers 1-3/8 to 2-1/4 inch doors, the Corbin Russwin CL3110 vandal resistant passage lever for 1-3/4 to 2 inch doors, and the BEST 9K Series 1DT single dummy trim for a door that needs a pull only. Trim styles will not match Sargent exactly across brands, so if appearance across the floor matters, keep the non-keyed sets within one line.
12) Is a Grade 2 cylindrical lever like the Hager 2580 an acceptable substitute for a Sargent 10XG71 on a high traffic opening?
They are built to different standards. The Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors, and 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. Both are mechanical and non-electrified. The Sargent 10XG71 is Grade 1 heavy duty, UL tested to 20 million cycles, and resists over 3,100 in-lb of locked lever torque and 1,600 lbs of offset lever pull. On a stairwell, corridor, or entry seeing constant use and abuse, the cycle and torque numbers are the reason a specifier writes Grade 1; a Grade 2 storeroom lever suits lower traffic doors such as storage and back of house.
13) Will an Emtek or Baldwin lever lock work as a replacement for a Sargent 10XG71 on a commercial door?
Those are residential and decorative trim lines rather than commercial cylindrical bodies. The Baldwin Estate 5103 comes as passage, privacy, and left or right hand half dummy levers with a 5048 rose, and the Emtek Classic Cortina and Arts and Crafts levers are sold as dummy pairs. Dummy levers have no latch at all and privacy levers use a thumbturn rather than a cylinder. The Sargent 10XG71 is a Grade 1 heavy duty commercial cylindrical lock, keyed single cylinder, non-handed, with a lockbody accepting fixed and interchangeable core cylinders. For a commercial opening with an access control circuit, the decorative levers are not a functional equivalent.
14) What Grade 1 lever pairs with a Sargent 10XG71 opening for the non-secured doors in the same corridor?
To keep the same grade across a corridor while only powering the controlled doors, the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for 1-3/4 inch to 2 inch doors, and the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. The Falcon K101 is a Grade 1 heavy duty non-handed passage lock covering 1-3/8 inch to 2-1/4 inch. Any of the three gives Grade 1 latching on the doors that need no lock function, while the Sargent 10XG71 handles the keyed fail secure openings. Lever style and rose design differ between the makers, so a facility standardizing on appearance should confirm trim before mixing brands.
15) Can a keypad lever such as the Delaney LP250 or Lockey 1150 replace a Sargent 10XG71 for controlled access?
They control access by a different method. The Delaney LP250 is a Grade 2 electronic keypad leverlock and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination, passage function, for 1-1/8 inch to 2 inch doors; the Emtek Classic keypad leverset is a further keypad option. All three put the credential in the lock itself as a code. The Sargent 10XG71 is a Grade 1 fail secure body that takes its lock signal from a building access control system and accepts fixed or interchangeable core cylinders keyed into a SARGENT key system. Standalone keypads suit a single door with no head end; the 10XG71 suits doors that must report to and be released by central access control.
16) For a healthcare or detention opening, is the Sargent 10XG71 the correct lock or is an asylum function needed?
Asylum function is its own thing and is keyed on both sides. The Dexter C1000 Asylum is the F87 asylum function in Grade 1 for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is an asylum lock with a ball knob and a conventional cylinder in Schlage C keyway. The Sargent 10XG71 is a keyed single cylinder fail secure lever and is offered with an optional Microshield antimicrobial coating for healthcare and food service environments. Use asylum function where both faces must be key controlled; use the 10XG71 where the opening is on access control and staff pass through on a credential.
17) Which lever should be used on a Sargent 10XG71 opening that is being converted to an exit device?
A cylindrical lock body does not carry over to a pushpad exit device. The Corbin Russwin 585F715 is a Grade 1 lock lever built as trim for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, for 1-3/4 inch to 2 inch doors, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim in entry function. If the opening changes from a bored lock to a rim or mortise exit device, the trim lever is the part to order and the 10XG71 body no longer applies. The Sargent 10XG71 remains the choice where the door keeps a bored cylindrical prep with a 2-3/8 inch to 5 inch backset.
18) What is the difference between the Sargent 10XG71 and a dummy lever when only the pull side of a pair of doors is being trimmed?
The inactive leaf of a pair takes a dummy, which has no latch and no lock function. The BEST 9K Series 1DT single dummy trim is a Grade 1 non-keyed heavy duty lever, the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever. Matching the Grade 1 dummy to a Grade 1 active leaf keeps the trim consistent across the pair. The Sargent 10XG71 is the keyed fail secure body for the active leaf that actually latches and locks.
19) Does an electrified Sargent 10X lock need a lot of power at the door?
Less than a conventional electrified lock. The electromechanical functions in the 10X Line use Sargent EcoFlex technology for up to 92 percent energy savings, which matters when you are sizing a power supply across a run of doors or feeding the lock through a transfer hinge. Fewer amps at each opening means more doors on the same supply.
20) Is there an antimicrobial lever option for a hospital or food service door?
Yes, the 10X Line offers an optional Microshield antimicrobial coating for healthcare, food service, and other spaces where surface contamination control matters. It is an ordering option on the lever and rose, not a separate lock, so the Grade 1 mechanical performance is unchanged.
21) What lever, rose, and finish does the Sargent 10XG71 come in?
The configuration is the L lever on the L rose in 26D satin chromium plated over nickel. 26D is the standard satin chrome that matches most commercial hardware already hanging in an office or institutional building, so a replacement on one door will not stand out against the closers, hinges, and exit devices on the rest of the openings.
22) Can I use a Sargent 10X Line cylindrical lock on an apartment or multi-tenant building?
Yes, it is a commercial-rated lock and multi-tenant residential is one of its intended applications, along with offices, schools, healthcare, retail, warehouses, and government buildings. For a property manager standardizing across a building, the draw is that it is non-handed and takes all Sargent key systems, so one lock covers every opening and every door can sit on the same master key plan.
23) Is a Grade 3 residential lever ever the right call over a Sargent 10XG71 in a multi-family building?
For interior unit doors, often yes; for the controlled entrances, no. 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 passage and Artino entrance leversets are Grade 3. Those suit bedroom, bath, and closet doors inside an apartment. The Sargent 10XG71 is a Grade 1 heavy duty commercial fail secure lever built for the building entry, corridor, and amenity doors that carry traffic from every tenant and sit on the access control system.
