Schlage L9000 Series Electrified Mortise Lock Case - Lockbody Only

The Schlage L9000 Series electrified mortise lock case is sold as a lockbody only - no trim, no cylinder, no rose. It is the electrified chassis that accepts L Series trim and cylinders separately, giving integrators and contractors the flexibility to specify finish and function independently. The case auto-detects 12V or 24V DC input, is field-reversible for handing, and ships with mounting screws and templates. Case size is 4-7/16" x 3-5/8" x 1". Standard backset is 2-3/4". Door thickness: 1-3/4".

Four variants are available. L9090LB supports L9090 and L9092 functions. L9091LB supports L9091, L9093, and L9095 functions. The RX suffix (L9090LB RX, L9091LB RX) adds a request-to-exit output for access control integration. Select the variant that matches the function and access control wiring requirements of the opening.

Schlage L9090LB – Frequently Asked Questions

1) What actually comes with a Schlage L9090LB electrified mortise lock case? Does it include the lever and trim?
It is the lockbody only. The lock case is furnished with mounting screws and templates and nothing else, so the lever or knob, the rose or escutcheon, the strike and any cylinder are separate line items. It is also supplied non-keyed. That is the point of buying the case on its own: it is the part you swap when an electrified chassis fails or when you are converting an existing L Series opening, not a complete lockset. The body itself measures 4-7/16 x 3-5/8 x 1 inches and is cold rolled steel with zinc dichromate plating.
2) Which Schlage lock case do I order for an L9092 or an L9095 function?
Two chassis cover all five functions. The L9090LB is the electrified case for L9090 and L9092. The L9091LB is the case for L9091, L9093 and L9095. Each one is also offered with request-to-exit built in, ordered as L9090LB RX or L9091LB RX. Settle the function code before anything else, because the case is what fixes it.
3) Will the Schlage L9000 electrified mortise case fit the door prep I already have?
The geometry to check is 1-3/4 inch door thickness and a 2-3/4 inch backset, with a case body of 4-7/16 x 3-5/8 x 1 inches. The standard latch is a spring latch on that same 2-3/4 inch backset. An opening already mortised for an L9000 pocket at 2-3/4 backset in a 1-3/4 inch door takes this case as-is. This case is listed for 1-3/4 inch doors; other door thicknesses are handled as a separate option within the L Series rather than by this case.
4) Do I have to specify left hand or right hand when ordering the L9090LB mortise case?
No hand to specify. The L9000 electrified mortise case is field reversible, so the same part number goes on a left hand or a right hand door and the latchbolt is turned at the opening. For a property manager or a shop stocking spares, that means one case number covers every door in the building instead of two.
5) Is this lock fail safe or fail secure, and can I change it after it is installed?
You choose. The L9000 electrified cases are customer-selectable EL or EU, so the same case can be set up either way rather than being locked in at the factory. EL is electrically locked, which leaves the outside lever unlocked when power drops. EU is electrically unlocked, which leaves it locked when power drops. Decide from the code requirement on that opening and the behavior your access control system expects. The electrified functions are UL19X listed for single-point locking applications.
6) My power supply is 24 volt. Do I need a different part number than the 12 volt version?
Same part number either way. The L9000 electrified lock cases auto detect 12V and 24V DC, so there is no voltage suffix to get wrong on the order and no wrong-voltage chassis sitting on the shelf. Wire it to whichever supply the opening already has.
7) Can I get request-to-exit and door status signals back to the access control panel from a Schlage L9000 electrified lock?
Yes. The electrified L9000 functions offer RX, DPS, latchbolt monitor and deadbolt monitor. RX is built into the case, so it is ordered on the chassis itself as L9090LB RX or L9091LB RX rather than added later. If the integrator wants the panel to see the lever being turned from the inside and the door position without a separate switch in the frame, specify the RX case up front.
8) I need the access control system to pull the latch back, not just unlock the lever. Is a Schlage L9090 the right lock?
Probably not. The L9000 electrified cases are EL/EU functions, meaning power controls whether the outside lever is locked; the latchbolt itself is not retracted electrically. If the opening has a push button, a card reader tied to an automatic operator, or anything that needs the latch withdrawn on a signal, you want motorized latch retraction instead. SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control for 1-3/4 inch doors. Command Access LPM110ECH is an electrified latch retraction mortise lock chassis running on 24VDC.
9) Can a Schlage L9000 electrified mortise lock go on a 3-hour fire rated door?
Yes. The L9000 is UL listed for 3-hour fire doors and UL/cUL listed for A label single doors up to 4 by 10 feet and pairs up to 8 by 10 feet. On the installed lock, the letter F together with the UL symbol on the latch front is what an inspector looks for to confirm the listing. Two functions in the wider family, L9076 and L9077, are outside that fire listing; the electrified cases here are not among them.
10) Does the Schlage L9000 mortise lock meet a Grade 1 spec and Buy American requirements for a government job?
Grade 1, tested and certified under ANSI/BHMA A156.13 for both security and operational, and it meets the Buy American Act. It also carries ANSI/ASTM F476-76 Grade 40 and is UL listed. One detail that changes the submittal: with interchangeable core cylinders the assembly rates Grade 2 security, while a concealed shell cylinder holds A156.13 Grade 1 operational and security. If the spec says Grade 1 security without qualification, the cylinder choice matters as much as the lock.
11) Is there another Grade 1 electrified mortise lock that fits the same 1-3/4 inch door as the Schlage L9090 lock case?
The SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset listed for a 1-3/4 inch door thickness, which is the same door thickness the Schlage L9090 electrified lock case is built for, and the L9090 case is Grade 1 as well. The working difference is what the electricity does at the lock. The SDC 7600 drives the latch back under 24VDC control, while the L9090 electrified case auto detects 12V or 24V DC and offers customer selectable EL or EU control of the outside lever. Both go into a mortise pocket, so the decision is whether the opening needs the latch retracted electrically or the outside lever locked and unlocked electrically.
12) My access control panel puts out 12V DC - which electrified mortise lock chassis will run on that?
The Schlage L9090 electrified lock case auto detects 12V or 24V DC, so it takes a 12V supply as it comes, in either the L9090LB chassis for L9090 and L9092 functions or the L9091LB chassis for L9091, L9093 and L9095 functions. Among the alternatives, the Command Access LPM110ECH is a 24VDC electrified latch retraction chassis, the Command Access LPM190-M-EU-CH is a 24V motorized mortise lock with electric unlock, and the SDC 7600 Series works under 24VDC control. Those three are specified at 24V, so an opening fed at 12V is the case where the Schlage electrified case is the direct fit.
13) Is the Command Access LPM110ECH a straight swap for a Schlage L9090 electrified mortise lock case?
They are both heavy duty electrified mortise parts, but they do different electrical jobs and are not interchangeable on the same opening. The Command Access LPM110ECH is an electrified latch retraction chassis running at 24VDC, meaning the current pulls the latch bolt itself back - the setup used when an automatic operator or a remote release has to open the door without anyone touching the lever. The Schlage L9090 electrified case is selectable EL or EU, which controls whether the outside lever is locked or unlocked, and the latch stays mechanical. If the drawing calls for electric latch retraction, the LPM110ECH or the SDC 7600 motorized latch retraction lockset is the part that answers it; if it calls for electric control of the outside trim, the L9090LB or L9091LB case is.
14) Will the 10-072 strike that goes with this Schlage mortise lock match my existing frame cutout?
The standard strike specified with the L9000 case is the 10-072: a 1-1/4 by 4-7/8 inch square corner strike with box and a 1-3/16 inch lip. If your frame is already cut for a square corner mortise strike at 1-1/4 by 4-7/8, it lines up. A frame prepped with radius corners needs a curved corner strike instead, and lip length has to suit how far the stop sits from the face of the frame, so a deeper stop or an applied trim can call for a longer lip. The strike is not furnished with the case; it is ordered separately.
15) We already run Schlage L Series locks through the building. Will an electrified opening still match the rest of the doors?
Visually, yes, because the trim is where the match happens and the trim is ordered separately from the case. The L Series carries 33 lever designs, two knob designs, five roses and three escutcheons across 14 finishes, and levers suite with Von Duprin exit devices along with the LE, LM9200, LM9300 and LT lines. So a card reader opening on an electrified case, an exit device at the stair and a mechanical mortise lock down the corridor can all read the same. Specify the lever and rose design you already have when you order the trim.
16) What other electrified mortise lock chassis could I use instead of the Schlage L9090LB?
Pick by function first, because that is what the chassis fixes. For a storeroom function, DynaLock EML-1 Series is an electrified mortise lock in storeroom function and Command Access ML1080LB is a heavy-duty storeroom function mortise lock chassis. Command Access LPM190-M-EU-CH is a 24V motorized storeroom mortise lock with electric unlock and optional REX. For an asylum, institution or utility function, Command Access ML04EU is the institutional version. The Schlage cases are ordered by L Series function code instead, with the L9090LB covering L9090 and L9092 and the L9091LB covering L9091, L9093 and L9095.
17) Which electrified mortise lock gives me a request to exit signal back to the panel?
On the Schlage side, RX is ordered into the part itself: the L9090LB RX is the electrified chassis with RX for L9090 and L9092 functions, and the L9091LB RX is the same for L9091, L9093 and L9095 functions, with DPS, latchbolt monitor and deadbolt monitor also available on the electrified L Series. Among the alternatives, the Command Access LPM190-M-EU-CH is a 24V motorized storeroom function mortise lock with electric unlock and optional REX, so the exit signal is added as an option on that chassis. Either way the integrator gets a dry signal when the inside lever is turned; the difference is whether it is specified as a distinct chassis part number or as an option on one.
18) The opening only needs one storeroom function - what is the alternative to a multi function electrified case?
The Schlage electrified case is built around function range: one L9090LB body covers the L9090 and L9092 functions and one L9091LB body covers L9091, L9093 and L9095. When a single fixed storeroom opening is all that is being covered, the DynaLock EML-1 is an EML series electrified mortise lock in storeroom function, the Command Access ML1080LB is a heavy duty storeroom function mortise lock chassis, and the Command Access LPM190-M-EU-CH is a heavy duty storeroom function motorized mortise lock. Those come defined as storeroom, where the Schlage case is selected into its function when it is trimmed out, which matters most to a shop standardizing one body across several different openings.
19) What electrified mortise lock should I look at for an asylum or utility room opening in a behavioral health facility?
The Command Access ML04EU is an institutional function electrified mortise lock chassis, heavy duty, with the function listed as asylum, institution and utility - the pattern where both sides are controlled rather than free egress from the inside lever. The Schlage L9000 electrified case covers the L9090, L9091, L9092, L9093 and L9095 electrified functions instead, and the L Series carries Gold Standard ligature resistant trim for behavioral health applications, so a facility can pair Schlage ligature resistant trim on the patient side openings and use an institutional function chassis where the opening calls for that specific function.
20) Is this lock case heavy enough for a main entrance or a high traffic corridor?
It is a commercial mortise case, not a light duty tubular. The L9000 exceeds ANSI/BHMA Grade 1 security and operational standards, and the case is cold rolled steel with zinc dichromate plating at 4-7/16 x 3-5/8 x 1 inches. Grade 1 is the top commercial tier under A156.13 and is what gets specified for entrances, stairwells and anything on a school or hospital traffic pattern.
21) The L9090LB chassis is listed as non-keyed. What cylinder do I use if the function needs one?
The case ships non-keyed, so keying is decided when you order the cylinder rather than with the lockbody. Within the L Series, the high security option is a UL437 listed cylinder, specified as the Primus 20-500 Series. Keep in mind how the cylinder type moves the rating: interchangeable core puts the assembly at Grade 2 security, while a concealed shell cylinder keeps A156.13 Grade 1 operational and security.
22) How does the SDC 7800 PRO compare with the Schlage L9000 electrified case on a door that takes abuse?
The SDC Selectric 7800 PRO is a solenoid controlled mortise lock with a vandal resistant clutch, listed for a 1-3/4 inch door, so the abuse protection sits in a clutch that lets the outside lever move without driving the hub. The Schlage L9000 electrified case is built for the same 1-3/4 inch door and handles the same problem through the security blocking hub, which stops picking by removing the levers, with Vandlgard free wheeling outside trim offered on most functions including the electrified ones. Two different mechanisms for the same failure mode - a clutch inside the lock body versus a free wheeling trim option on the outside lever.
23) Do the Command Access alternatives come as bare chassis the way the Schlage L9000 electrified part does?
Yes. The Command Access LPM110ECH electrified latch retraction chassis, the ML1080LB storeroom function chassis and the ML04EU institutional function chassis are all chassis level parts, the same scope of supply as the Schlage L9000 electrified lock case, which is furnished with mounting screws and templates only. On the Schlage side that means levers, rose or escutcheon, cylinder and strike are ordered separately, with the 10-072 1-1/4 by 4-7/8 inch square corner box strike as the standard strike and a 2-3/4 inch backset spring latch as the standard latch. A distributor quoting any of these needs to price the trim package alongside the body rather than assuming a complete lockset.

    My Honest Take on the Schlage L9000 Electrified Mortise Lock!

    Posted by Lucas on Aug 7th 2023

    I got the Schlage L9000 Electrified Mortise Lock from ZenSupply. The lockbody's quality is excellent, ensuring sturdy security for my business. However, the installation instructions were a bit unclear, making it a bit challenging to set up initially. Once installed, though, it has been working flawlessly, and I'm satisfied with its performance.
