Schlage L9457P 06A 626 – Frequently Asked Questions

1) How does the L9457 classroom security function actually work for a teacher locking down a room?
The teacher locks the door from inside the classroom with a key, no need to step into the corridor. Either key throws the deadbolt, and throwing the deadbolt locks the outside lever. The inside lever is always free, and turning it retracts both the deadbolt and the latchbolt at once while unlocking the outside lever, so a single motion gets everyone out and doesn't leave the door dead-bolted behind them. Both sides take a key, which is what the double cylinder designation means.
2) Will the Schlage L9457 latch into the strike already in my frame?
It ships with the 10-072 strike, a 1-1/4 x 4-7/8 inch square corner box strike with a 1-3/16 inch lip. If your frame is cut for a standard ANSI 4-7/8 inch square corner mortise strike, the prep lines up. Rounded-corner frame preps and older non-ANSI cutouts do not, and the frame will need to be modified or a matching strike specified. Lip length is worth checking against your frame reveal, since 1-3/16 inches is what the standard strike gives you.
3) Do I have to specify handing when I order the L9457?
The L9457 lock body is field reversible, so for most lever designs you don't specify hand at all. The exception is the 12 lever, which is handed and requires you to call out right hand or left hand on the order. The other eight lever designs (01, 02, 03, 05, 06, 07, 17, 18) don't need it.
4) Can I get the L9457 keyed alike with the rest of my building's locks?
Yes. Keyed alike is a selectable option, alongside keyed different, which is the standard. The stock cylinder is a conventional 6-pin in the C keyway. If your facility runs its own keyway or an existing masterkey system, order it less cylinder and install your own cylinders, then key them into the system you already have. Special keying instructions can be written into the order.
5) Is the Schlage L9457 rated for a fire door?
The L Series latch is UL listed for 3-hour fire doors, and the listing covers 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 you confirm a given lock carries it. It is ANSI/BHMA A156.13 Series 1000 Grade 1 Operational and Grade 1 Security, and the function code is F33.
6) Does putting an interchangeable core in the L9457 change its ANSI grade?
It changes the security grade, not the operational grade. With the standard conventional cylinder the lock is Grade 1 operational and Grade 1 security. Fit an FSIC interchangeable core and it stays Grade 1 operational but drops to Grade 2 security; with an SFIC core it's Grade 1 operational and Grade 3 security. If your spec calls for Grade 1 security outright, stay with the conventional 6-pin cylinder or a concealed shell cylinder, which holds A156.13 Grade 1 operational and security.
7) What's the difference between the L9457 classroom security lock and a plain classroom function lock?
A standard classroom function is keyed on the outside only, so locking the room means going into the corridor and locking from that side. The L9457 adds a deadbolt keyed from both sides, so the room can be secured from inside without opening the door, and throwing that deadbolt is what locks the outside lever. If you want ordinary corridor-side classroom locking instead, a straight classroom function mortise lock such as the Cal-Royal NM8070 or the Corbin Russwin ML2003 covers it, both Grade 1 for 1-3/4 inch doors.
8) Can I put the L9457 on a 1-3/8 inch interior wood door?
No. The L9457 is specified for 1-3/4 inch doors, and 1-3/8 inches is the common older interior thickness that this lock is not cut for. A thinner leaf also may not carry a mortise pocket sized for a 4-7/16 x 6-1/16 x 1 inch case. For classroom-type locking on a lighter door, look at a bored lockset instead of a mortise, or replace the leaf with a 1-3/4 inch door.
9) What is the closest Grade 1 mortise classroom lock to the Schlage L9457 from another manufacturer?
The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series built for 1-3/4 inch doors, the same door thickness the L9457 is built for. The Cal-Royal NM8070 is another Grade 1 heavy duty classroom mortise lockset for 1-3/4 inch doors, with an auxiliary deadlatch. Note the function difference: the L9457 is classroom security, where the deadbolt is thrown or retracted by key from either side and throwing the deadbolt locks the outside lever, while the ML2003 and NM8070 are catalogued with the standard classroom function.
10) What should I use if I want keypad or credential control on a classroom door instead of a keyed mortise lock?
The Schlage L9457 is a mechanical lock with no electronic component, keyed with a conventional 6-pin C keyway cylinder. For credential-based control on a classroom opening, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the FME-4000 adds an electronic intruder classroom function with RFID on the same 1-3/4 inch door thickness. The Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with classroom function and 300 user codes for doors 1-5/8 to 1-7/8 inches thick.
11) Can I use a Sargent 4874 double cylinder deadbolt in place of the Schlage L9457?
No, they do different jobs on the door. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which is deadbolt only with no latchbolt and no lever. The L9457 also runs a 2-3/4 inch backset and is keyed double cylinder, but it combines a latchbolt retracted by lever from either side with a key-operated deadbolt, and the inside lever retracts both bolts for immediate egress. If a lever and latching function are needed on the opening, a deadbolt-only body such as the 4874 or the Kaba Ilco 185 Series will not cover it.
12) The door is 1-5/8 inches thick. Will the Schlage L9457 fit, and what else is available?
The Schlage L9457 is specified for a 1-3/4 inch door thickness. For a thinner leaf, the Alarm Lock DL2700CR is a Grade 1 classroom function electronic mortise lock with weatherproof design covering 1-5/8 to 1-7/8 inch doors, and the DL3500CR covers the same 1-5/8 to 1-7/8 inch range with 300 user codes. Both are keypad locks rather than keyed mechanical locks.
13) Will a Baldwin 6301 mortise lock body work where a Schlage L9457 is specified?
The backsets do not match. The Baldwin 6301 is an entrance/apartment mortise lock body with a 2-1/2 inch backset, offered knob by knob and as the 6301LS lever by lever, for doors 1-3/4 inch and over. The Schlage L9457 uses a 2-3/4 inch backset with a 4-7/16 by 6-1/16 by 1 inch case, so the door prep is different and the two are not interchangeable in an existing mortise pocket.
14) Can I tell from the hallway whether a classroom door is locked?
Not with the base L9457, which is a mechanical lock with no status display. Schlage offers a 180 degree visibility indicator as an L Series option, so specify the indicator version if staff need to read lock status at a glance. If an indicator is a requirement and you're open to other brands, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches.
15) What do I need to pick before ordering a Schlage L9457?
Four choices plus keying. Lever design: 01, 02, 03, 05, 06, 07, 12, 17 or 18, with hand called out only on the 12. Rose or escutcheon: A wrought rose, B wrought rose, L full face escutcheon, or N escutcheon. Finish: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, or 630 satin stainless. Cylinder: conventional 6-pin in the C keyway, or less cylinder if you're supplying your own. Then keyed different, keyed alike, or your own keying instructions.
16) Will the L9457 lever match the exit devices and other locks already in my building?
Schlage L Series levers suite with Von Duprin exit devices and with the related L Series products LE, LM9200, LM9300 and LT, so a classroom door on the L9457 can carry the same lever and finish as the exit device on the stair door down the hall. Match the lever design and the finish code across the openings, since both are specified per lock. Eight finishes are offered, from 605 bright brass through 630 satin stainless.
17) Is the L9457 mortise lock built for high traffic school corridors?
It's a heavy duty commercial lock, ANSI/BHMA A156.13 Series 1000 Grade 1 for both operation and security. The case is cold rolled steel with zinc dichromate plating. Deadbolt functions carry an anti-saw pin in the bolt against cut-through, and a security blocking hub keeps the lock from being picked by pulling the levers off. It also meets ADA requirements and the Buy American Act.
18) Can the L9457 be tied into an access control system or card reader?
No. The L9457 is a mechanical lock with no electrified option in this configuration. For credentialed access on a mortise prep, Schlage Electronics has the CO-100 standalone keypad mortise lock and the ENGAGE LEMD wireless mortise lock with a 125kHz proximity reader, and TownSteel's FME-2000 is a Grade 1 classroom mortise lockset with RFID for 1-3/4 inch doors. Schlage's L Series also offers motor-driven electrified functions with 12V/24V DC auto detect and selectable EL/EU, ordered as a different function.
19) I need a plain deadbolt, not a full lockset. Is the L9457 the wrong part?
Yes, if all you want is a bolt. The L9457 is a complete lever lockset with both a latchbolt and a deadbolt in one mortise case, sized 4-7/16 x 6-1/16 x 1 inches. For a deadbolt alone on a mortise prep, the Sargent 4874 is a double cylinder mortise deadbolt with the same 2-3/4 inch backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt.
20) What other Grade 1 mortise locks work for a 1-3/4 inch classroom door if the Schlage L9457 isn't a fit?
Several mechanical Grade 1 options cover the same 1-3/4 inch door. The Corbin Russwin ML2003 from the ML2000 Series is a Grade 1 mortise classroom lockset. Cal-Royal's NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch, and the NM8080 is the storeroom version with an interchangeable core option. For behavioral health or other anti-ligature settings, TownSteel's MRX-L-01 and MRX-A-01 are Grade 1 heavy duty ligature resistant mortise locksets for 1-3/4 inch doors, though both are passage function rather than keyed.
21) Does the L9457 meet ADA and California code for lever return?
The L Series meets ADA requirements, and under the California Referenced Standards Code all levers with a return to door of 1/2 inch or less comply. Since the L9457 is a lever lock, pick a lever design that carries that return if you're building in California. The lock also holds Miami-Dade NOAs and Florida Building Commission listings, and ANSI/ASTM F476-76 Grade 40, UL listed.
22) Can I get a high security cylinder in the Schlage L9457?
Yes. A UL437 listed locking cylinder is an option on the L Series, specified as a Primus 20-500 Series cylinder. The lock ships standard with a conventional 6-pin cylinder in the C keyway, so if you want the high security cylinder either specify it or order the lock less cylinder and fit your own.
23) Which mortise lock should I order if the door does not need a deadbolt, only keyed entry?
The Schlage L9457 carries a deadbolt actuated by either key, which is what makes it a classroom security function. Where the opening only needs keyed entry with no deadbolt, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For an office style opening, the Cal-Royal NM8050 is a Grade 1 entrance/office mortise lockset on the same 1-3/4 inch door thickness.
24) What is the difference between the Schlage L9457 and the Sargent 7925 for a dormitory corridor door?
The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. The Schlage L9457 is a heavy duty Grade 1 mortise lock with a double cylinder keyed deadbolt operated by key from either side, and throwing that deadbolt locks the outside lever. The single versus double cylinder deadbolt is the deciding detail: the 7925 takes a cylinder on one side, the L9457 is keyed on both.
25) Is the BEST 45HCA intruder function lockbody the same thing as the Schlage L9457 classroom security lock?
They are close in intent but not the same part. The BEST 45HCA is a heavy duty mortise lockbody with intruder function in the 40H Series, sold as a lock body. The Schlage L9457 is a complete heavy duty classroom security lockset with lever trim, where the deadbolt is thrown or retracted by key from either side, throwing the deadbolt locks the outside lever, and actuating the inside lever retracts both bolts. Trim on the L9457 is ordered as part of the lock across nine lever styles and four rose and escutcheon designs.
26) I need a mortise lock for a behavioral health room, not a classroom. What replaces the Schlage L9457?
The TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function on 1-3/4 inch doors with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. All three are passage function with no locking, where the L9457 is a keyed classroom security lock with a double cylinder deadbolt.
27) Which Schlage mortise lock gives me access control reporting instead of the mechanical L9457?
The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile enabled deadbolt with LED and Greenwich trim, right hand, fire rated 3 hours. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors. The L9457 is a mechanical Grade 1 mortise lock, keyed with a conventional 6-pin C keyway cylinder and no electronic component.
28) What mortise lock matches the Schlage L9457 door prep if the opening only needs passage or privacy?
The Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset, the same backset the L9457 uses, and the 3810E is the escutcheon version, both for doors 1-3/4 to 2-1/2 inches. The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors, and the 3850E is a Grade 1 office function mortise lock with lever and escutcheon, non-keyed, on the same 2-3/4 inch backset. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, matching the field reversible handing of the L9457.
29) Is the Marks USA 21AC or 22AC a substitute for the Schlage L9457 double cylinder mortise lock?
Both are double cylinder mortise locks, but they are built for different doors. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, listed for a 1 inch door thickness. The Schlage L9457 is a commercial heavy duty lock for a 1-3/4 inch door with a 4-7/16 by 6-1/16 by 1 inch case, so an ornamental iron narrow stile door will not take it.
30) I need an electrified mortise lock on the same opening as a Schlage L9457. What are the options?
The Command Access ML190 is a heavy-duty motorized mortise lock in storeroom function with field selectable EL/EU operation on 24VDC. The BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation. The Schlage L9457 itself is a mechanical lock with no electronic component, though electrified functions exist within the L Series and auto detect 12V/24V DC with customer-selectable EL/EU.
31) Does an Emtek mortise entrance lockset work as a lower cost alternative to the Schlage L9457?
No, those are not functional locks. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are all dummy function, meaning trim with no latching or locking mechanism. The Schlage L9457 is a Grade 1 keyed classroom security lock whose latchbolt retracts by lever from either side with a key-operated deadbolt, so a dummy set cannot stand in for it on an operating door.
32) Can I order a Sargent 130KB thumbturn to convert a Schlage L9457 to inside thumbturn operation?
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, both trim pieces for Sargent mortise locks rather than Schlage. The L9457 is a double cylinder function where the deadbolt is thrown or retracted by key from either side, so it takes a conventional 6-pin C keyway cylinder on both sides, not a thumbturn.
33) Does the L9457 come with matching trim on both sides of the door?
Yes. The standard build gives you the same lever, rose and finish on both sides, with the coordinating latch and strike included. You pick one lever design and one rose or escutcheon (A or B wrought rose, L full face escutcheon, or N escutcheon) and it applies to both faces. The lever bushing locks in place so there are no exposed screws on the inside levers.
34) For a public entrance rather than a classroom, what mortise lock replaces the Schlage L9457?
The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, matching the field reversible handing of the L9457. If the entrance needs a lockable outside lever tied to a keyed deadbolt, the L9457 keeps that behavior: the deadbolt is thrown by key from either side and throwing it locks the outside lever, while the inside lever stays free for immediate egress.
35) What Grade 1 mortise lock should I use for a bed or bath opening instead of the Schlage L9457?
The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches. Both are privacy function with no keying. The L9457 is a keyed double cylinder lock built for classroom security, where the deadbolt is operated by key rather than by an inside turn.
