Schlage L9456P 17A 626 OS-LOC – Frequently Asked Questions

1) Will the Schlage L9456 corridor mortise lock fit my 1-3/4 inch commercial door with a 2-3/4 inch backset prep?
That is exactly the prep the L9456 is built for. It's a 2-3/4 inch backset mortise lock made for 1-3/4 inch doors, with a lock case measuring 4-7/16 x 6-1/16 x 1 inches and a 1-1/4 x 8 inch armor front. If your existing pocket was cut for a standard ANSI mortise body, the case drops in. Doors thicker or thinner than 1-3/4 inches need a different door thickness option specified.
2) What does corridor function actually do on a Schlage L9456, and how is it different from a classroom lock?
Corridor function is a deadbolt-and-latch combination. Levers on both sides always retract the latchbolt. Throwing the deadbolt, by key outside or thumbturn inside, locks the outside lever. Turning the inside lever pulls back both the deadbolt and the latch and unlocks the outside lever again, so egress is never blocked and the door self-restores to unlocked on the way out. A classroom lock has no deadbolt and stays locked outside until re-keyed. Pick corridor where someone inside the room needs to lock the door instantly by thumbturn and where an exiting occupant should not leave it locked behind them.
3) Does the LOCKED/UNLOCKED indicator on the Schlage L9456 read from the outside of the door?
Yes, this build carries the 180 degree visibility indicator on the outside face, showing LOCKED or UNLOCKED. That is why buyers spec it for restrooms, exam rooms, and single-occupancy corridor doors, staff can read the door status from down the hall without touching the lever. The indicator reports the deadbolt position, which is what actually locks the outside lever on a corridor function.
4) Do I have to order a cylinder with the Schlage L9456, or can I use my building's existing cores?
Four cylinder choices cover it. P gives you a conventional 6-pin cylinder in C keyway, ready to key. J is Schlage FSIC prepped and shipped less core, B is SFIC prepped less core, both for buildings already running interchangeable cores. L is less conventional cylinder, for a locksmith supplying the mortise cylinder. If you already stock cores, order B or J and drop your own in. A note for spec writers: the description states Grade 1 operational and security with the standard cylinder, Grade 2 security with FSIC and Grade 3 security with SFIC.
5) Will the Schlage L9456 latch into the strike already in my frame?
The lock ships with a 10-072 strike, 1-1/4 x 4-7/8 inches, square corner, 1-3/16 inch lip, with a box. That is the standard ANSI square-corner mortise strike, so if your frame is prepped for an ANSI 4-7/8 inch strike it lines up. Two things to check on a retrofit: your frame may have a curved (radius) corner cutout rather than square, and the 1-3/16 inch lip has to clear your stop and trim without projecting into the opening. Also confirm the frame has depth for the box, a corridor function throws a deadbolt as well as a latch.
6) Can the Schlage L9456 go on a 3-hour fire rated door?
Yes. The L9000 mortise locks are UL listed for 3-hour fire doors (the exceptions are the L9076 and L9077 functions, not this one), and UL/cUL listed for A label single doors up to 4 by 10 feet and pairs up to 8 by 10 feet. The letter F and the UL symbol stamped on the latch front are how the inspector confirms the listing in the field. The latch is ANSI/BHMA A156.13-2012 Series 1000 Grade 1 operational and Grade 1 security, and it meets ADA requirements and the Buy American Act.
7) My building has 1-3/8 inch interior doors. Will the Schlage L9456 work on them?
No. This build is a single door thickness lock, 1-3/4 inches, which is the standard commercial door. A 1-3/8 inch door needs a different door thickness option specified from the L Series options portfolio, which includes different door thicknesses. Don't try to shim it, the case, spindle length and trim are all cut for 1-3/4.
8) What is the closest equivalent to a Schlage L9456 corridor mortise lock from another manufacturer?
The Sargent 7925 is the nearest match in function. Both are Grade 1 heavy duty mortise locks carrying a corridor/dormitory function with a single cylinder deadbolt: the Sargent 7925 is listed as a Dormitory Exit Function Mortise Lock with Rose Trim and Single Cylinder Deadbolt, and the Schlage L9456 is a Grade 1 corridor function with a single cylinder keyed lever and a deadbolt thrown by key outside or inside thumbturn. Both throw a deadbolt that locks the outside lever while the inside lever stays free for egress. The Schlage comes with a 2-3/4 inch backset and a 10-072 1-1/4 inch x 4-7/8 inch square corner box strike, so confirm the Sargent trim and strike prep against the existing door cutout before swapping.
9) Is a Grade 1 storeroom mortise lock a substitute for the Schlage L9456?
No - they secure the door differently. The Accentra 8805FL and the Cal-Royal NM8080 are both Grade 1 storeroom function mortise locks, which keep the outside lever locked at all times with key entry. The Schlage L9456 is a corridor function: the outside lever operates freely until the deadbolt is thrown by key or inside thumbturn, and turning the inside lever retracts both bolts and unlocks the outside lever again. If the occupant needs to be able to secure the door from inside without a key, storeroom function will not do it.
10) Which mortise lock fits a 1-5/8 inch thick door if the Schlage L9456 does not?
The L9456 is built for a 1-3/4 inch door. If the leaf is thinner, the Alarm Lock Trilogy locks cover a 1-5/8 inch to 1-7/8 inch range: the DL2700CR is a Grade 1 classroom function electronic mortise lock with weatherproof design, the DL3500CR is a Grade 1 classroom function with 300 user codes, and the DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad. All three are electronic rather than keyed, so confirm the function matches how the opening has to be secured before ordering.
11) Can I key the Schlage L9456 alike with the other locks I'm ordering for the same building?
Keyed alike is a selectable option, alongside keyed different as standard and a less-cylinder choice for shops doing their own keying. Order keyed alike when a set of doors should open on one key, keyed different when each opening needs its own. If you're running an existing masterkey system, take the less-core or less-cylinder route and pin to your own system rather than the factory C keyway.
12) Which rose or escutcheon do I pick for a Schlage L9456, and does it change the door prep?
Four trim styles: A wrought rose, B wrought rose, L full face escutcheon, and N escutcheon. Roses are the compact round trim; escutcheons are the tall plate that covers more of the door face. On an indicator corridor lock the escutcheon options carry the trim differently than a rose does, so this is a decision to make before the door is prepped, not after. If you're replacing an older lock and want to hide existing screw holes or a previous escutcheon footprint, the L full face is the one that covers the most face. Match whatever is on the adjacent openings if you're standardizing a floor.
13) What finishes does the Schlage L9456 come in to match the rest of my building's hardware?
Twelve finishes: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, and 643E aged bronze. In commercial buildings 626 satin chrome and 630 satin stainless are the two that show up most, so if you're matching existing corridor doors those are the likely codes on your current hardware. The 17 lever design and the finish carry on both sides of the door with a matching latch and strike.
14) Will the Schlage L9456 levers match the Von Duprin exit devices already on my building?
They will. All L Series levers suite with Von Duprin exit devices and with the related L Series products LE, LM9200, LM9300 and LT. That matters on a floor where the stair doors run exit devices and the corridor doors run mortise locks, you can hold one lever design and one finish across both. The 17 lever is the design on this build.
15) What's the difference between a Schlage L9456 corridor lock and a Sargent 7925 dormitory function mortise lock?
Both are Grade 1 heavy duty mortise locks with a single cylinder deadbolt for the same kind of opening. The Sargent 7925 is a 7900 Series dormitory/exit function with rose trim. The Schlage L9456 is L Series corridor function with a deadbolt that locks the outside lever, and it's specified here with the outside LOCKED/UNLOCKED indicator, which is the reason to choose it over the Sargent if staff need to read door status from the hallway. If your building is already standardized on Sargent keyways and prep, the 7925 keeps you in one system; if it's a Schlage house, stay with the L9456.
16) I need a mortise lock with a status indicator but I'm not a Schlage house. What else is there?
The Marks USA LA318GJ is the other indicator mortise lockset carried here, a classroom security indicator lockset, Grade 1, for 1-3/4 inch doors, supplied with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches. Note the functional difference before you swap: the Marks is a classroom security function, keyed from inside to lock the outside lever, while the L9456 is corridor function where a thumbturn throws a deadbolt and the inside lever clears it on the way out. For a restroom or single-occupancy door the corridor thumbturn is what people expect; for a classroom lockdown the Marks is the closer match.
17) Is the Schlage L9456 an electronic lock, and what should I order instead if I want access control on that opening?
No, the L9456 is a mechanical lock, key and thumbturn only, no wiring or credentials. If the opening needs credentialed access, ZenSupply carries the Schlage Electronics LEMD Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and mobile-enabled operation, 3 hour fire rating, and the TownSteel FME-2000 Grade 1 RFID mortise lockset for 1-3/4 inch doors. One caution on mixing: those are credential-based openings and won't read the same as a mechanical indicator door, so decide per opening rather than per floor.
18) How secure is the Schlage L9456 deadbolt against someone attacking the lock or pulling the lever off?
Two specific defenses. The deadbolt carries an anti-saw pin inside the bolt to stop cut-through, and a security blocking hub prevents picking the lock by removing the levers, which is the attack a lot of older mortise locks are open to. The lock case is cold rolled steel with zinc dichromate plating, rated heavy duty, and the L9000 line exceeds ANSI/BHMA Grade 1 security and operational standards plus ANSI/ASTM F476-76 Grade 40. If you need a high security cylinder on top of that, the UL437 listed option is a Primus 20-500 Series cylinder.
19) Does the Schlage L9456 need to be ordered handed?
Order the trim to the door's hand. On a corridor function the inside is the side with the thumbturn and the free lever, and the outside is the keyed, indicated side, so which face gets which is not something you can flip after the fact the way you can with a plain passage lock. Stand outside the door, note whether the hinges are on your left or right and which way the door swings, and give that hand with the order.
20) Which office function mortise lock should I look at instead of a corridor lock?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for a 1-3/4 inch door, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset. Office function locks and unlocks the outside lever without throwing a deadbolt. The Schlage L9456 corridor function ties the outside lever to the deadbolt - throwing it locks the outside lever, and turning the inside lever retracts both bolts. Pick office where the tenant wants to lock up without projecting a bolt into the frame.
21) If I want keypad access instead of a keyed mortise lock on a corridor door, what replaces the L9456?
The L9456 is a mechanical, non-electronic keyed lever mortise lock with a conventional 6-pin C keyway cylinder. For credential access on the same door, the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader for a 1-3/4 inch door, and the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes. Both are electronic locksets rather than key-and-thumbturn, so the deadbolt behavior of the L9456 corridor function does not carry over - check the function each one offers against how the corridor door needs to be secured.
22) Is there a simpler mortise lock than the L9456 for a door that only needs a privacy deadbolt and no key?
Yes. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a deadbolt for a 1-3/4 inch door, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset. Both drop the keyed cylinder that the L9456 carries - the L9456 is a keyed single cylinder lock supplied with a conventional 6-pin C keyway cylinder. Choose privacy only where no one needs key access from the corridor side.
23) Can a Baldwin 6301 mortise lock body replace a Schlage L9456?
Not without changing the door prep. The Baldwin 6301 is an entrance/apartment mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over, offered knob by knob or lever by lever. The Schlage L9456 uses a 2-3/4 inch backset with a 4-7/16 inch x 6-1/16 inch x 1 inch case, so the cylinder hole and case pocket sit differently in the stile. The functions differ as well - entrance/apartment against the L9456 corridor function where throwing the deadbolt locks the outside lever.
24) What mortise lock do I use for a behavioral health room instead of the L9456?
For ligature resistant openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with a passage function for a 1-3/4 inch door, and the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless. All three are passage function, so they do not lock - the L9456 is a keyed corridor lock with a deadbolt, and if the room needs to be secured you need a ligature resistant trim on a locking function rather than these.
25) What do I order if the door only needs a passage mortise lock and no cylinder at all?
The Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset, with the 3810E as the escutcheon version. All are passage function with no locking. The Schlage L9456 is keyed single cylinder with a deadbolt, so dropping to passage removes both the key control and the deadbolt - the 2-3/4 inch backset on the Hager units matches the L9456 backset if you are reusing the door prep.
26) What is the difference between the Schlage L9456 and the Schlage LE mortise locks?
The L9456 is a mechanical Grade 1 keyed mortise lock with a conventional 6-pin C keyway cylinder and a corridor deadbolt function. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED on Greenwich trim, right hand, with a 3 hour fire rating. The LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions on a 1-3/4 inch door with a 3 hour fire rating. If credentials and audit are part of the spec, the LE units carry the reader; the L9456 is key and thumbturn.
27) Can the Schlage L9456 lock body be converted to another function later if the room's use changes?
To a degree, yes. The L Series uses a universal lock case that supports 10 different functions from a single lock body, and the series carries 55 plus standard functions overall. For a facility standardizing on one part number across a floor, that means a case installed today can be reconfigured rather than replaced when a room changes use. The 180 degree indicator and Vandlgard free-wheeling outside trim are options on the line, and Vandlgard is available on most functions.
28) How does the Schlage L9456 compare to a BEST 45H public entrance mortise lock?
The BEST 45H is a heavy duty mortise lock body with a public entrance function and field reversible operation, and the 45HCA intruder version is a heavy duty lock body with an intruder function. Both of those are lock bodies. The Schlage L9456 is supplied as a complete keyed lever lockset with a 17 lever design, a conventional 6-pin C keyway cylinder and a 10-072 square corner box strike, in a 4-7/16 inch x 6-1/16 inch x 1 inch case. If you already have Schlage trim on the door and only need the case, a body-only BEST unit is a different order shape than a complete lockset.
29) Is an Emtek mortise entrance lockset an alternative to the Schlage L9456?
No. The Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane mortise entrance locksets are all dummy function - they are trim that does not latch or lock. The Schlage L9456 is a commercial Grade 1 heavy duty keyed lockset whose latchbolt is retracted by the lever from either side with a deadbolt thrown by key or thumbturn. Emtek dummy trim belongs on an inactive leaf, not on a corridor door that has to secure.
30) Is a Sargent 130KB thumbturn a replacement for the inside thumbturn on an L9456?
No - the Sargent 130KB is a standard duty mortise thumbturn from the 8200 series and the 130W is a standard duty mortise thumbturn with a round backplate from the 7800 series. Those are trim pieces for Sargent mortise cases. The Schlage L9456 is a complete Grade 1 heavy duty lockset whose deadbolt is thrown or retracted by key outside or inside thumbturn, with its thumbturn matched to the L series case. Order the thumbturn against the lock body brand it mounts to.
