Sargent 10XG44 Grade 1 Cylindrical Lock — Service Station Function

The Sargent 10XG44 is a heavy-duty Grade 1 cylindrical leverset configured for the Service Station function (ANSI F92): the outside lever is always locked and can be unlocked by key or push-button; the inside lever releases via a coin-slot turn. This makes it the right choice for attended service counters, utility rooms, and controlled-access commercial spaces where staff need quick inside egress but outside entry must remain controlled at all times.

Sargent 10XG44 LB 26D – Frequently Asked Questions

1) What does the Sargent 10XG44 service station function actually do at the door?
Service station is ANSI F92: the outside lever stays locked at all times and is released by key or by the push-button, while the inside lever is always free to exit and can be released by a coin-slot turn. It suits an attended counter or a utility room where staff need to walk out without a key but nobody comes in from the outside without one. It is a single-cylinder, keyed lock with a deadbolting latch.
2) Do I have to specify handing when ordering a Sargent 10X cylindrical lever lock?
No handing to specify. The 10X Line cylindrical lock is non-handed, so one part number covers left and right hand openings. That is what makes it workable for a property manager stocking spares across a building: one lock on the shelf fits whichever door fails next.
3) Can the Sargent 10XG44 go on a fire rated door?
Yes. It is UL/cUL listed for use up to a 3-hour fire door and is NFPA 80 compliant. It is also ADA compliant and Florida Building Code approved under FL# 2998, with windstorm certification. For a stairwell or corridor opening in a hospital or school, that combination is usually what the AHJ is looking for.
4) Can I get the Sargent 10XG44 keyed into my existing Sargent master key system?
Yes. The lockbody takes every cylinder format Sargent offers, fixed core through interchangeable core, and works with all Sargent key systems including large format IC. On the order you pick the cylinder (6-pin standard, 60 for Sargent large format IC, or 70 for small format IC), the keying (keyed different, keyed alike, or master keyed), and the keyway. LA is the standard keyway, with 40 others available including the CA through CR, HA through HK, LB through LL, R, RA through RL, S and U families. Give us the existing keyway and system when you order and it can be pinned to match.
5) What is the closest Grade 1 cylindrical keyed lever to a Sargent 10XG44 if the door already runs a Corbin Russwin cylinder program?
Stay inside the Corbin Russwin CL3300 series. The Sargent 10XG44 is a Grade 1 cylindrical keyed leverset with the Service Station function, non-handed, and the Corbin Russwin CL3300 line covers the same Grade 1 cylindrical lever territory - the CL3300 series lever for the ED8000 pushpad device and CL3300 cylindrical lock series is listed for 1-3/4 inch to 2 inch doors. The functions are not the same part number for part number, so match the function on the door schedule before you swap the brand.
6) Service Station keeps the outside lever locked at all times - what should I use instead if staff need to key the outside lever open and leave it unlocked during business hours?
That is an entry/office function, not Service Station. The Sargent 10XG44 carries the Service Station function, where outside entry stays controlled. For an opening that needs to be set unlocked for the day, the Dexter C1000 Entry/Office is a Grade 1 cylindrical lever with the Entrance/Office function for 1-3/8 inch to 1-3/4 inch doors, and the Falcon B511CP6D is a Grade 2 cylindrical lever with the same Entrance/Office function.
7) I need a storeroom lock, not a service station lock - what is the equivalent?
Storeroom keeps the outside lever locked with no push-button or inside coin release, so it is a different function from the Sargent 10XG44 Service Station. 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, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. Both are Grade 2 where the 10XG44 is Grade 1, which matters if the spec calls for heavy duty.
8) What is the difference between service station and storeroom function, and which one do I want?
Both keep the outside lever locked and the inside lever always free. The difference is what unlocks the outside: on a storeroom lock like the Cal-Royal AG05 or the Hager 2580, only the key retracts the latch, and it relocks the moment you let go. Service station adds a push-button and a coin-slot release, so a staff member can button the outside lever open for a delivery window and turn it back off from inside. Want a door that can never be left unlocked by accident? Take storeroom. Want staff control over when the outside opens? Service station.
9) What lever and rose combinations does the Sargent 10X Line come in, and can I match my existing doors?
Three lever styles, B, L and P, on either a G Rose or an L Rose, across 14 finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B, 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 suede and WSP white suede powder coat. 26D is the usual commercial default. Pull the finish code off the back of an existing lock or the door schedule and order the same code so the new door reads identical to the rest of the floor.
10) Is there an electrified version of the Sargent 10X lock for access control?
The 10X Line's electromechanical variants use EcoFlex, which cuts energy draw by up to 92% against conventional electromechanical locksets without giving up cycle life or holding force. They work with Wave to Open, Request to Exit, and Door Position Switch applications. There is a dedicated installation instruction sheet for the 10X Line electrified bored lock. If the opening is card reader controlled, that is the path; the mechanical 10XG44 on its own has no electrical connection.
11) My door is thinner than 1-3/8 inch. Will the Sargent 10XG44 work?
No. The 10X Line cylindrical lock covers 1-3/8 to 2 inches and nothing below that. For a thinner door, the Lockey 1150 mechanical keypad lever set is rated from 1-1/8 inch up to 2 inches. Keep in mind that is a keypad lock, not a keyed cylindrical lock, so the keying and function behave differently.
12) The door next to my service counter does not need to lock at all - is there a cheaper Grade 1 lever that matches?
For an opening that only needs latching, a passage lever keeps the Grade 1 heavy duty level of the Sargent 10XG44 without a cylinder. The Falcon K101 is a Grade 1 heavy duty non-handed passage cylindrical lock, fire rated, for 1-3/8 inch to 2-1/4 inch doors; the Falcon T101 is a Grade 1 heavy duty passage lever in the T Series; and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for 1-3/4 inch to 2 inch doors. None of these are keyed - the 10XG44 is.
13) Can I use a Grade 2 lever in place of the Sargent 10XG44 on a high traffic service door?
Grade 2 is a lower ANSI/BHMA level than the Grade 1 heavy duty rating the Sargent 10XG44 carries, so it is a different spec, not a like-for-like swap - if the door schedule says Grade 1, a Grade 2 lever such as the Hager 2525 Grade 2 commercial entry lock or the Falcon B101 Grade 2 medium duty passage lever will not meet it. Grade 1 alternates in the same cylindrical lever class include the Dexter C1000 Classroom and the Corbin Russwin CL3110, both Grade 1, though each carries a different function.
14) Is a dummy lever trim an acceptable match for the Sargent 10XG44 on the inactive leaf of a pair?
A dummy is trim only - it has no latch and no cylinder, so it cannot do the keyed Service Station duty the Sargent 10XG44 does, but it is the correct part for a fixed inactive leaf you want to look the same. The BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim cylindrical lever, and the BEST 7KC Series 1DT is the Grade 2 medium duty single dummy equivalent.
15) What should go on a utility or behavioral health door where a Service Station lock is not the right function?
Those openings usually call for an asylum or institutional function, which keys both sides rather than leaving an inside release. The Sargent 10XG44 is a single cylinder Service Station lock with an inside coin-slot release. The Dexter C1000 Asylum is a Grade 1 cylindrical lock with the Asylum F87 function for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty Grade 2 asylum lock with a ball knob and a Schlage C keyway conventional cylinder.
16) The opening needs to release on a fire alarm or access control signal - what replaces the mechanical Sargent 10XG44?
Mechanical Service Station has no electrical release, so an electrified cylindrical lever is the swap. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC for 1-3/4 inch to 2 inch doors, available with an NZ lever and D rose. Note the 10XG44 is a keyed mechanical Grade 1 lock, so the door prep and the wiring path are the decision, not the grade.
17) I run Schlage keyways in the building - does that rule out the Sargent 10XG44?
The Sargent 10XG44 is built for Sargent key systems, with keyways from LA standard through the C, H, L and R families and R, S and U, in 6 pin standard, Sargent large format interchangeable core and small format interchangeable core. If the building is keyed Schlage C, levers cut for that keyway include the Cal-Royal AG00 entrance lever with a 6 pin Schlage C keyway keyed different on a 2-3/8 inch backset and the Cal-Royal AG03 classroom lever with the Schlage C keyway on a 2-3/4 inch backset. There is also an adapter path in the Accentra 107S Schlage cylinder adapter kit, though that one is made for Yale hardware.
18) What Grade 1 lever should I use on a classroom door where the Sargent 10XG44 Service Station function is not permitted?
Classroom and classroom security functions are written for those openings. The Sargent 10XG44 holds the outside lever locked at all times with a key or push-button unlock, which is not what a classroom schedule usually calls for. The Dexter C1000 Classroom is a Grade 1 keyed clutching cylindrical lever with the Classroom function for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Classroom Security is the Grade 1 clutching keyed version of the Classroom Security function over the same door thickness range.
19) My door is 1-3/8 inch thick - which comparable levers still fit if I move off the Sargent 10XG44?
The Sargent 10XG44 covers 1-3/8 inch to 2 inch doors, so thin doors are already in range. If you do substitute, the Falcon K101 spans 1-3/8 inch to 2-1/4 inch, the Dexter C1000 Asylum spans 1-3/8 inch to 2 inch, and the Hager 2510 spans 1-3/8 inch to 2 inch. Levers such as the Corbin Russwin CL3110 and the Design Hardware X75 start at 1-3/4 inch and will not cover a 1-3/8 inch door.
20) I need a matching dummy or passage lever for the other doors in the same suite. What pairs with a Grade 1 cylindrical leverset?
For the non-keyed openings on the same run, stay at Grade 1 so the feel and durability match: the BEST 9K Series 1DT single dummy trim and the Design Hardware X75 passage lever are both Grade 1 non-keyed cylindrical levers, and the Falcon K101 is a Grade 1 heavy duty passage lock rated for 1-3/8 to 2-1/4 inch doors with a fire rating. Dropping to a Grade 2 dummy like the BEST 7KC 1DT saves on a closet door nobody touches, but it will not wear the same as the keyed doors beside it.
21) What paperwork do I get for installing a Sargent 10X cylindrical lockset?
Sargent publishes the 10X Line cylindrical lockset installation instructions, a separate sheet for the electrified bored lock, a full 10X Line parts manual for replacement components down the road, and the Sargent full line catalog. The parts manual is the one a maintenance shop wants on file, since it lets you order a single spindle or rose rather than a whole lock when something wears.
22) Can I put a keypad lever on the service counter door instead of keying a Sargent 10XG44?
A keypad lever swaps the key for a code, which changes how the door is managed - no keyway, no master key hierarchy. The Sargent 10XG44 accepts Sargent large format and small format interchangeable cores and standard 6 pin cylinders, with keyed different, keyed alike and master keying. If codes suit the door better, 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, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Neither integrates into a Sargent key system.
23) Is a residential grade lever set an alternative to the Sargent 10XG44 for a small commercial building?
They are built to different standards. The Sargent 10XG44 is a Grade 1 heavy duty commercial cylindrical leverset. Grade 3 levers such as the Kwikset 200BRNL Breton passage set for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 300BRNL Breton privacy set, and the Callan Artino Grade 3 entrance leverset are residential grade and non-keyed or privacy-only in the passage and privacy cases, so they do not carry the Service Station function or the Grade 1 level.
24) Does a privacy lever do the same job as a Service Station lock?
No. Privacy locks from the inside with no key on the outside, while the Sargent 10XG44 Service Station keeps the outside lever locked and keyed, with a coin-slot release on the inside. If the door is a restroom or a changing room rather than a counter, the Hager 2540 Grade 2 privacy cylindrical lock with the Withnell lever covers 1-3/8 inch to 2 inch doors and the Arrow MK02-TA is a fire rated privacy cylindrical lock with a Tudor knob, non-keyed, for 1-3/4 inch to 2 inch doors.
