Sargent 10XG24 LB 26D – Frequently Asked Questions

1) Will the Sargent 10XG24 entrance lock fit a 1-3/8 inch door?
Yes. The 10XG24 cylindrical lock covers door thicknesses from 1-3/8 inches up to 2 inches, so it works on older 1-3/8 inch interior doors as well as standard 1-3/4 inch commercial doors and thicker 2 inch openings. That range is the whole span the lock accepts, so you do not need a separate thick-door kit anywhere inside it.
2) Do I need to specify handing when ordering a Sargent 10XG24 lever lock?
No handing to specify. The 10XG24 is non-handed, so one lock covers a left- or right-hand door and you can stock a single part across a building instead of splitting your inventory two ways. What you do have to specify is backset, strike, cylinder type, keying and keyway.
3) Can the Sargent 10XG24 take an interchangeable core so it works with our existing key system?
Cylinder format is an ordering choice. You can take the 6 pin standard cylinder, the 60 prefix Sargent large format interchangeable core (FSIC), or the 70 prefix small format interchangeable core (SFIC). The lockbody accepts all cylinder formats from fixed through interchangeable core and works with SARGENT key systems, so a facility already on SFIC can add these locks to the existing system rather than starting a second one.
4) Can I get Sargent 10X Line entrance locks keyed alike or on a master key system?
Yes, all four keying setups are available: standard keying, keyed different, keyed alike, and master keying. Keyed alike is what you want when one key should open a run of doors in the same suite; master keying is for a building where a maintenance key needs to open everything under individual tenant keys. Keyway is specified separately, with LA as the standard and 40 further keyways available including the CA, HA, LB, RA and S families.
5) Is the Sargent 10XG24 fire rated and ADA compliant for a healthcare or school corridor?
Both. The 10X Line entrance lock is UL-cUL fire rated up to 3 hours, ADA compliant, Florida Building Code approved and windstorm certified. It is also Grade 1 and independently verified at 20 million cycles under the UL Cycle Above and Beyond test, which is well past what ANSI/BHMA Grade 1 requires. On a rated corridor door in a hospital or school, that combination covers the fire assembly, the accessibility requirement and the traffic.
6) Is there a lighter duty entrance lever than the Sargent 10XG24 for a low traffic office door?
Yes. The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever in the same Entrance/Office function, and the Hager 2525 is a Grade 2 commercial cylindrical entry lever for doors 1-3/8 inch to 2 inch. Both deliver the entrance function without the 20 million cycle heavy duty construction of the Grade 1 Sargent 10XG24. Interior office and tenant suite doors that see light daily traffic are where the Grade 2 options fit; main entries and corridor doors are where the 10XG24 belongs.
7) The door needs to stay locked at all times with key entry only. What do I use instead of the 10XG24?
The 10XG24 is an entrance function lock, where a push button on the inside controls whether the outside lever is locked. For an opening that must remain locked continuously, a storeroom function lock is the right part: the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. Storeroom keeps the outside lever locked and the key retracts the latch every time, with no button for an occupant to leave in the unlocked position.
8) What should I order for a classroom door instead of the Sargent 10XG24 entrance lock?
Classroom doors call for a classroom function rather than entrance. The Dexter C1000 classroom lever is Grade 1 with a clutching keyed design for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Classroom Security lever is Grade 1 in the classroom security function for the same thickness range. The Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset. The Sargent 10XG24 entrance function uses an inside push button to control the outside lever, which is not how a classroom opening is meant to be secured.
9) The building is keyed to Schlage C. Does that rule out the Sargent 10XG24?
It is the question to settle before ordering. The Sargent 10XG24 ships in SARGENT keyways, with LA standard and CA through U available, and the lockbody integrates with SARGENT key systems in 6 pin standard, large format interchangeable core and small format interchangeable core cylinders. Peers built around the Schlage C keyway include the Cal-Royal AG00 entrance lever, Grade 2, with a 6-pin Schlage C cylinder keyed different and a 2-3/8 inch backset. There is also the Accentra 107S Schlage cylinder adapter kit, a Grade 1 part made for fitting Schlage cylinders to Yale hardware.
10) Can I standardize a whole facility on the Sargent 10XG24, or do I need other functions from the same class?
The 10XG24 covers the entrance/office doors. To hold Grade 1 across the rest of the facility, the Corbin Russwin CL3110 handles passage and closet as a Grade 1 vandal resistant fire rated lever, the Dexter C1000 covers classroom, classroom security and asylum in Grade 1, and the BEST 9K 1DT provides Grade 1 dummy trim for inactive leaves. The 10XG24 itself is non-handed with a 2-3/4 inch standard backset and backsets from 2-3/8 inch to 5 inch, which keeps one part number working across doors with different bore locations.
11) Is a Grade 1 cylindrical lock worth it over a Grade 2 entry lever on a high-traffic door?
On a door that gets hundreds of cycles a day, yes. The Sargent 10X Line is Grade 1 heavy duty, verified at 20 million cycles, and resists over 3,100 in-lb of locked lever torque and 1,600 lbs of offset lever pull. Grade 2 entry levers like the Hager 2525 or the Falcon B511CP6D are medium duty and are the sensible pick on a low-traffic interior office door where nobody hangs off the lever. Where the cost of a failure is a callback on a tenant entrance or a school corridor, the heavier lock is the cheaper one.
12) What is EcoFlex on the Sargent 10X Line, and do I need it for a card reader or wave-to-open door?
EcoFlex is the energy-saving electrification on the 10X Line, cutting current draw by up to 92 percent on electromechanical functions. It matters when the lock is tied into wave to open, request to exit or a door position switch, because a lower draw means smaller power supply budget across a building full of electrified openings. On a straight mechanical entrance door with a key and push button, EcoFlex is not something you have to design around.
13) Is a cylindrical lock like the Sargent 10XG24 the right choice, or should I be looking at a mortise lock?
A cylindrical bored lock goes into two round holes plus a latch bore, so it is faster to install and to replace than a mortise lock and it is what most commercial doors are already prepped for. The 10X Line takes that format to Grade 1 heavy duty with 20 million verified cycles, which closes most of the durability gap people used to cite as the reason to mortise. If your doors are already mortise-prepped, stay with a mortise lock rather than filling and re-boring. If you are prepping new doors or replacing existing bored hardware, cylindrical is the straightforward path.
14) I need an electrified version of a Grade 1 cylindrical lever. Is the Sargent 10XG24 it?
The 10XG24 is a mechanical single cylinder entrance lever built on the 10X Line body, which carries EcoFlex technology for up to 92 percent energy savings on the line's electromechanical functions. If the opening needs an electrified lock now, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever at 12VAC/DC for 1-3/4 inch to 2 inch doors, available with the NZ lever and D rose. Fail safe unlocks on loss of power, so confirm the opening's egress and fire strategy calls for that behavior before specifying it.
15) Which non-keyed Grade 1 lever matches the Sargent 10XG24 for doors that do not need a key?
For openings on the same run that only need to latch, the Falcon K101 is a Grade 1 heavy duty passage lever, fire rated, with non-handed levers for 1-3/8 inch to 2-1/4 inch doors, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for 1-3/4 inch to 2 inch doors. The Sargent 10XG24 is keyed with a single cylinder, so on a corridor of mixed doors the passage units cover the closets and non-secured rooms while the 10XG24 handles the ones that lock.
16) Can I use a Grade 3 entrance lever like the Cal-Royal AUS00 in place of the Sargent 10XG24?
They share the Entrance/Office function but not the duty class. The Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for doors 1-3/8 inch to 1-3/4 inch, and the Callan Artino is a Grade 3 entrance leverset. The Sargent 10XG24 is Grade 1 heavy duty, verified at 20 million cycles and rated for more than 3,100 in-lb of locked lever torque. Where a specification or facility standard calls out Grade 1, the Grade 3 levers will not satisfy it; for a light-use interior door in a small building they carry the same function.
17) Is a dummy lever like the BEST 9K 1DT a substitute for the Sargent 10XG24 on an inactive leaf?
No, and the distinction matters when ordering for a pair of doors. The BEST 9K 1DT is a Grade 1 non-keyed heavy duty single dummy trim lever, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever. A dummy is a fixed pull with no latch and no cylinder. The Sargent 10XG24 is a keyed single cylinder entrance lock with a working latchbolt, so the active leaf takes the 10XG24 and the inactive leaf takes the dummy trim.
18) For a restroom or bedroom door, what do I use instead of a keyed entrance lever?
A privacy function, not an entrance function. The Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed and fire rated. The Sargent 10XG24 is keyed with a single cylinder for outside key entry, which a restroom does not want. Note the Arrow is a knob rather than a lever, so it will not meet an ADA-driven lever requirement.
19) What is the difference between the Sargent 10XG24 and a keypad lever like the Lockey 1150?
Credential type and cylinder. The Lockey 1150 is a heavy duty mechanical keypad lever set with a double combination for doors 1-1/8 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those open on a code with no key. The Sargent 10XG24 is a keyed single cylinder lock whose lockbody accepts fixed, large format interchangeable and small format interchangeable cylinders and integrates with SARGENT key systems, so it belongs on a building already on a master key system rather than one running codes.
20) Which lever should I use for a detention or utility room instead of the 10XG24 entrance lock?
An asylum or institution function. The Dexter C1000 Asylum is a Grade 1 asylum/institution/utility cylindrical lock for doors 1-3/8 inch to 2 inch, matching the thickness range of the Sargent 10XG24, 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 is keyed on both sides with no free egress from the inside lever, which is the opposite of the 10XG24 entrance function where the inside lever always retracts the latch.
21) I need a Grade 1 lever with a decorative look for a hospitality corridor. How does the 10XG24 compare to the Baldwin and Emtek levers?
Different products for different jobs. The Baldwin Estate 5103 with the 5048 rose comes in passage, privacy and left or right hand half dummy, and the Emtek Classic Cortina and Arts and Crafts levers are sold as dummy pairs. Those are decorative trim functions, with the half dummy and dummy versions having no latch at all. The Sargent 10XG24 is a Grade 1 heavy duty keyed entrance lock offered in B, L and P levers on G or L roses, in finishes from bright brass and satin bronze through oil rubbed dark bronze and black or white suede powder coat, so the decorative range sits on a commercial lockbody.
22) Will a Grade 1 passage lever from Design Hardware or Falcon work on a 2 inch door like the Sargent 10XG24 does?
Check the thickness before you commit. The Sargent 10XG24 covers 1-3/8 inch to 2 inch doors. The Design Hardware X75 is a Grade 1 passage lever specified for 1-3/4 inch doors, and the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology. The Falcon K101 Grade 1 passage covers 1-3/8 inch to 2-1/4 inch, so on a thick door it is the passage counterpart that keeps pace with the 10XG24 range.
23) What lever and rose styles does the Sargent 10X Line come in, and what finishes are available?
Three lever profiles, B, L and P, on either a G rose or an L rose, in wrought brass or bronze. Fourteen finishes are offered, including 26D satin chrome and 26 bright chrome, 03 and 04 brass, 09 and 10 bronze, the 10B, 10BE and 10BL dark oxidized bronzes, 14 and 15 nickel, 20D dark statuary bronze, and black or white suede powder coat. If you are matching existing hardware across a building, 26D satin chrome is the usual commercial standard.
24) Will the push button on a Sargent 10X Line lever survive being slammed into a door stop?
That is the case it was built for. The 10X Line uses a push/turn button design that avoids damage from door stops and walls, and the lock prohibits entry after more than 100 vertical impacts, twenty times the ANSI/BHMA requirement. On a door that swings hard into a wall stop, or in a corridor where levers get kicked and hung on, that vandal resistance is what keeps the button working.
