Schlage L9453R03A626 – Frequently Asked Questions

1) Will the Schlage L9453 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
Yes on both counts. The L9453 is built for 1-3/4 inch doors and uses the standard 2-3/4 inch mortise backset, which is the normal commercial mortise prep. The lock case itself measures 4-7/16 x 6-1/16 x 1 inches and mortises into the edge of the door. If your doors are thicker than 1-3/4 inches, this is not the right lock as specified.
2) What does the L9453 entry/office function actually do at the door?
It is an entrance/office function with a deadbolt. The latchbolt retracts by lever from either side until the outside lever is made inoperative, either by key from outside or by the inside thumbturn. With the outside locked, the key outside or the inside lever still retracts the bolt, so the inside is always free for egress. An auxiliary deadlatch holds the latchbolt against carding. That makes it the usual choice for an office or suite door where staff lock down the outside lever when they leave and want a deadbolt thrown as well.
3) Is the Schlage L9453 mortise lock rated for a fire door?
It is UL Listed for a 3-hour fire door and is certified to ANSI/BHMA A156.13-2012, Grade 1, function F04. That covers most commercial and institutional stair, corridor and suite openings where a labeled door is required. It is a heavy duty, commercial-rated lock, not a residential one.
4) What strike comes with the L9453 and will it drop into my existing mortise frame prep?
The standard strike is the Schlage 10-072, a 1-1/4 by 4-7/8 inch square corner strike with a box and a 1-3/16 inch lip length. That is the common ANSI mortise strike size, so if your frames are already prepped for an ANSI 4-7/8 inch strike it lands in the existing cutout. Frames with a T-strike or a non-ANSI prep will need to be modified or a different strike ordered.
5) Does the Schlage L9453 need to be ordered handed, or is it field reversible?
Order it handed. The L9453 is listed as handed, so you need to establish the hand of the opening before you order. Determine it from outside the door: if the hinges are on your right and the door swings away from you, that is right hand.
6) What keyway and cylinder does the Schlage L9453 use, and can I key it into my existing Schlage master system?
It ships with a conventional 6-pin cylinder in the Schlage C keyway, single cylinder keyed. If your building is already on Schlage C, it keys alike or masters into that system without swapping keyways. Buildings running a restricted or non-C keyway will need cylinders in that keyway instead.
7) What is the closest cross-brand equivalent to the Schlage L9453R entrance/office mortise lock?
The Cal-Royal NM8050 is the nearest match by function and door prep. It is a heavy duty Grade 1 mortise lockset with entrance/office function and an auxiliary deadlatch, fitted to 1-3/4 inch doors - the same Grade 1 entrance/office duty and the same 1-3/4 inch door thickness the L9453 is built for. The difference to confirm before ordering is trim and keying: the L9453 runs the Schlage C keyway with a conventional 6-pin cylinder and 2-3/4 inch backset.
8) What is the difference between the Schlage L9453 and a storeroom mortise lock like the Accentra 8805FL?
Function is the whole difference. The L9453 is entrance/office: the latchbolt retracts from either side unless the outside is made inoperative by key or by the inside thumbturn, so staff can secure the door from within. The Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom lockset with an interchangeable core option - storeroom keeps the outside lever locked at all times and entry is by key only. Choose entrance/office where the room is occupied and needs to be locked from inside, storeroom where it should never be left unsecured.
9) Will a Baldwin 6301 or 6310 mortise lock body drop into the same prep as the L9453?
Not without checking the prep. The Baldwin 6301 entrance/apartment and 6310 entrance/storeroom mortise lock bodies are both 2-1/2 inch backset, while the L9453 is 2-3/4 inch backset with a 1-1/4 x 4-7/8 inch ANSI square corner strike. That quarter inch difference moves the cylinder and spindle centerline relative to the door edge, so the two are not interchangeable in an existing cutout.
10) Which lever and rose options do I have to pick when ordering the Schlage L9000 mortise lock?
Two choices on the order form. Lever design comes as 02, 03, 06, 07 or 17, and the rose comes as A wrought rose or B wrought rose. All combinations are offered in 626 satin chrome. Pick the lever design that matches the other openings in the building, since the 03 and 06 have different shapes and will look obviously different side by side on the same corridor.
11) What is the L9453 lock body made of and will it hold up in a high traffic corridor?
The case is cold rolled steel with zinc dichromate plating, and the lock is rated Heavy Duty, ANSI/BHMA Grade 1. Grade 1 is the highest commercial rating in A156.13, which is what you want on school corridors, hospital wings and multi-family entries rather than a Grade 2 lock.
12) I need the same opening but with classroom or storeroom function instead of office. What should I look at?
Entry/office is not the right function for a classroom or a storeroom, because the outside lever can be left unlocked. For classroom function, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset. For storeroom, where the outside lever is always locked and the key retracts the latch, look at the Accentra 8805FL or the Cal-Royal NM8080.
13) Is there a non-keyed mortise lock I can use on interior doors that do not need a cylinder?
Yes. The L9453 is a keyed single-cylinder entrance/office lock, so it is more than you need on a door that never locks. For passage, 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 - the same backset the L9453 uses. The Hager 3850E is a non-keyed office mortise lock with lever and escutcheon, also 2-3/4 inch backset.
14) Can I get the same office function with a keypad instead of a key?
Not from the L9453 itself - it is a mechanical, non-electronic lock keyed to a 6-pin C keyway cylinder. If you want credential entry on the same opening, the Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock covering privacy, office and apartment functions, rated Grade 2, 3 hour fire rating, for 1-3/4 inch doors. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for 1-5/8 to 1-7/8 inch doors. Confirm grade and door thickness against your spec before swapping.
15) I only need to add a deadbolt to an existing door - do I have to buy the full L9453 lockset?
No. The L9453 is a complete mortise lockset combining latchbolt, deadbolt and lever trim. If the opening already has a latch and you only need the bolt, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, matching the L9453 backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. Those are bolt-only and carry no lever trim.
16) Are the Emtek mortise entrance locksets a substitute for the L9453?
No. The Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are all dummy function - they mount trim only and have no working latch, bolt or cylinder. The L9453 is a keyed single-cylinder entrance/office lock with a working latchbolt and deadbolt in a 4-7/16 x 6-1/16 x 1 inch mortise case. Use the Emtek dummy sets on an inactive leaf, not as a replacement for an operating lock.
17) What mortise lock should I use for a behavioral health or ligature-resistant opening instead of the L9453?
The L9453 uses a 03-style lever with a 2-13/16 inch projection, which is not suited to anti-ligature applications. For those rooms, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. All three are passage function, so they will not give you the keyed office locking the L9453 provides.
18) I need a mortise lock that supports interchangeable cores for a keying program - what are my options?
The L9453R is supplied for large format interchangeable core in the Schlage C keyway, with a conventional 6-pin cylinder as the standard cylinder reference. If you are specifying across brands, the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset offered with an interchangeable core option on 1-3/4 inch doors. Note the function change from entrance/office to storeroom when you make that swap.
19) For a dormitory corridor door, is the L9453 the right function or is there a better mortise lock?
The L9453 entrance/office locks the outside lever by key or inside thumbturn and leaves the inside always free. For a dorm corridor where the occupant needs a deadbolt with exit function, the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory mortise lock with rose trim and a single cylinder deadbolt. Both carry a deadbolt; the difference is the dormitory exit sequence versus the office thumbturn lock the L9453 uses.
20) I need a privacy mortise lock with a deadbolt for a restroom rather than an office lock - what should I order?
The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset - the same backset as the L9453. Both give you the privacy bolt without the keyed outside cylinder that the L9453 carries as a single cylinder keyed lock.
21) Is the Schlage L9453 an electronic or access control lock?
No. It is a purely mechanical, key and thumbturn operated mortise lock with no electronics, no reader and no wiring. If the opening needs credentials or audit trail, a mortise lock like the Schlage Electronics LEMD Grade 1 ENGAGE wireless mortise lock or the Dormakaba E-Plex 5086 pushbutton mortise lock covers that instead.
22) How far does the lever stick out from the door face on the Schlage L9000 mortise lock?
The lever runs 4-3/4 inches long with a 2-13/16 inch projection off the face, on a 2-1/8 inch diameter rose. Worth checking on narrow corridors, door pockets and wall stops, and against the latch faceplate size of 1-1/4 by 8 inches when you lay out the door prep.
23) Is the Codelocks CL2255 a lighter-duty alternative to the L9453?
It is a different class of product. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in brushed steel from the CL2000 Series. The L9453 is a heavy duty Grade 1 mechanical mortise lockset with a full 4-7/16 x 6-1/16 x 1 inch case, latchbolt and deadbolt. If the opening is specified Grade 1 commercial, the CL2255 will not meet it.
24) Can I replace just the mortise lock body and keep my existing trim instead of buying the complete L9453?
If the trim is staying, a lock body on its own may be the cleaner order. The BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA Series is a heavy duty mortise lockbody with intruder function. The L9453 ships as a complete lockset with lever and rose trim and is handed, so confirm handing and trim before deciding which way to go.
