TownSteel MSE-W-T-08-626 – Frequently Asked Questions

1) What backset and faceplate size does the TownSteel MSE-W mortise lock use, and will it drop into an existing mortise pocket?
The MSE-W mortise lock runs a 2-3/4 inch backset with a 1-1/4 inch x 8 inch stainless steel faceplate, which is the standard commercial mortise pocket prep. The latch bolt is a split, anti-friction stainless bolt with 3/4 inch projection and it ships with an ANSI strike in plated/stainless steel, so it lands in a standard ANSI 4-7/8 inch strike prep. If your existing pocket was cut for a 2-3/4 inch backset ANSI lock body, this goes in the same cutout.
2) What does the front door / corridor function actually do on a day to day basis?
Corridor function means the outside lever is locked or unlocked by the key from outside, and the inside lever always retracts the latch for free egress. It is a single cylinder lock, so there is a cylinder outside and a thumb turn inside (brass, Classic Visible style as standard) rather than a second keyed cylinder. Typical uses are building front entrances, dormitory corridor doors and apartment corridor doors where staff want to key the outside open during business hours.
3) Do I have to specify handing when I order this TownSteel mortise lock?
Yes, handing is a required selection: LH, RH, LHR or RHR. Reverse bevel (LHR/RHR) is the one people get wrong on out-swinging exterior doors, so stand outside the door, note which side the hinges are on and whether the door swings toward you or away, before you pick. Keying is also a required choice at order time: keyed different, keyed alike for a group of locks, or a specific key code you supply.
4) How much door face does the wide escutcheon cover, and will it fit a narrow stile door?
The escutcheon measures 10-9/16 x 2-3/8 x 9/32 inches and is brass, plated to match the lever finish. At 2-3/8 inches across the narrow dimension it needs a reasonably wide stile, so it is aimed at flush wood or hollow metal doors, not narrow stile aluminum storefront. For an aluminum glass door you would be looking at a different lock type entirely, such as the Kaba Ilco BR Series bottom rail lock.
5) Can I get the TownSteel MSE-W set up for our small format interchangeable core system?
Yes. The cylinder choice is either Standard or SFIC Prep, Less Core. Ordering SFIC prep means the lock arrives without a core so you can drop in your own small format interchangeable core and keep the whole building on one system. Pick Standard if you want a conventional cylinder supplied with the lock.
6) Is the TownSteel MSE-W an electronic lock, and can it be tied into access control?
The MSE-W is a mechanical, key-operated mortise lock, not electronic. If you need the opening on a credential system, look at an electrified mortise instead, such as the Schlage L9092EU with electric lock/unlock outside lever and request-to-exit at 12/24VDC, or the BEST 45HW wired electromechanical mortise lock in 12V/24V.
7) I need a corridor lock but with a separate deadbolt. Is this the right one?
No. The MSE-W is a single cylinder corridor lock with a latch bolt and guard bolt only, no deadbolt. For a corridor/dormitory opening with a single cylinder deadbolt built in, the Sargent 7925 dormitory exit function Grade 1 mortise lock covers that. If you only need the deadbolt itself, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, which matches this lock's backset.
8) What is the closest mechanical equivalent to the TownSteel MSE-W corridor mortise lock from another manufacturer?
The Sargent 7925 is the nearest match in mechanical terms: it is a Grade 1 heavy duty mortise lock in the 7900 Series with a corridor/dormitory function and a single cylinder deadbolt. The TownSteel MSE-W is also Grade 1 heavy duty with a corridor function and single cylinder keying. The difference is trim style - the MSE-W uses a wide escutcheon measuring 10-9/16 inches by 2-3/8 inches, while the Sargent 7925 is furnished with rose trim, so the door face prep and appearance differ even though the lock function lines up.
9) If the opening needs a storeroom function instead of corridor, what mortise lock should I use?
Move to a storeroom-function lock body rather than the TownSteel MSE-W, which is built as a corridor function. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset offered with an interchangeable core option, which matters if you are keying into an SFIC system - the MSE-W itself can be ordered with SFIC prep less core.
10) I need a classroom function mortise lock for a school corridor - is the TownSteel MSE-W the right choice?
No. The TownSteel MSE-W is a corridor function with a single cylinder, so it does not give the classroom keyed-outside-lever behavior. For classroom duty, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors.
11) If I need access control on a corridor door, what electrified mortise lock compares to the TownSteel MSE-W?
The TownSteel MSE-W is a mechanical lock, not electronic, though it is built to be integrated into access control systems and can be ordered with status sensors such as REX, privacy, door ajar, and mechanical key override. If you want the electrified lock body itself, the Schlage L9092EU with 03A trim is a heavy duty corridor-function mortise lock, keyed outside, with electric lock/unlock of the outside lever, request-to-exit, and 12/24VDC operation on 1-3/4 inch doors. The Command Access ML190 is a motorized mortise lock with field selectable EL/EU operation at 24VDC in a storeroom function.
12) Is this TownSteel mortise lock rated for high traffic commercial openings?
It is a Grade 1 heavy duty commercial mortise lock. The wear parts back that up: stainless steel latch bolt and guard bolt, stainless faceplate, stainless rocker-type stop works, and forged brass or cast zinc levers plated to the finish. Grade 1 is the top ANSI/BHMA tier and the usual spec for schools, healthcare, multi-family and institutional corridors.
13) Which lever styles can I get on the MSE-W, and can I match the rest of the building?
Eight lever styles are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango. Finish is 626 satin chrome, with the levers in forged brass or cast zinc plated to match. Since 626 is the most common commercial finish, it lines up with the satin chrome hardware already on most institutional and multi-family openings.
14) Should I use an escutcheon trim mortise lock or a rose trim one?
Escutcheon trim like the MSE-W uses a single long plate covering the cylinder, lever and thumb turn, which hides old prep scars and gives a more finished look on a front entrance. Rose trim uses separate round plates and is lighter on the door face. Hager's 3800 Series shows both approaches in the same function: the 3810E passage is the escutcheon version and the 3810S is the rose version, both on a 2-3/4 inch backset. Pick escutcheon when you want coverage and a heavier appearance, rose when you are matching existing round trim.
15) Can I order a run of these keyed alike for a building?
Yes. Keying is a required choice on every order: KD keyed different is standard, KA keyed alike is the option when you want one key to run several openings, and you can supply a specific key code for special keying. Ordering SFIC prep less core instead lets your locksmith core them into an existing masterkey system.
16) What is the difference between the TownSteel MSE-W corridor lock and a storeroom function mortise lock?
Corridor function lets a key change the state of the outside lever, so staff can leave the door unlocked during the day and key it locked after hours. Storeroom function keeps the outside lever locked at all times, with the key only retracting the latch, and there is nothing to accidentally leave unlocked. If storeroom is what the drawing calls for, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock with the Arcadia lever.
17) Is there a non-keyed mortise lock with escutcheon trim similar to the TownSteel MSE-W?
Yes. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon trim, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches thick, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon on the same 2-3/4 inch backset. Both share the 2-3/4 inch backset used by the TownSteel MSE-W, which is a keyed single cylinder lock, so the Hager options suit openings where no key is wanted.
18) Which mortise lock should I use for a privacy bathroom door instead of the TownSteel MSE-W?
The TownSteel MSE-W is a keyed corridor function, not a privacy set. For bed and bath privacy, 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 for doors 1-3/4 to 2 inches thick.
19) What is the difference between the TownSteel MSE-W and the Baldwin 6301 entry/apartment mortise lock?
Backset and trim are the two practical differences. The Baldwin 6301 is an entry/apartment function mortise lock body on a 2-1/2 inch backset, offered knob by knob or, as the 6301LS, lever by lever, for doors 1-3/4 inches and over. The TownSteel MSE-W is a corridor function on a 2-3/4 inch backset with a wide brass escutcheon 10-9/16 inches by 2-3/8 inches and a 1-1/4 by 8 inch stainless faceplate, so the two are not interchangeable in an existing door prep.
20) Can I standardize a facility on the TownSteel MSE-W, or do I need a passage lock on some openings?
Openings that must never lock - hall and closet doors - take a passage lock rather than the keyed single cylinder TownSteel MSE-W. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. Keeping the MSE-W on corridor and entry doors and a passage lock elsewhere gives one mortise prep across the building.
21) What heavy duty mortise lock bodies are comparable if I only need the lock body without trim?
The BEST 45H Series is a heavy duty mortise lock body in a public entrance function with field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody with an intruder function. Both are body-only items. The TownSteel MSE-W is supplied as a complete heavy duty Grade 1 unit with lever, wide brass escutcheon, ANSI strike and thumb turn, and it is ordered handed as LH, RH, LHR or RHR rather than field reversed.
22) Is a mortise thumbturn like the Sargent 130KB a substitute for the TownSteel MSE-W?
No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, and the Sargent 130W is a mortise thumbturn with a round backplate in the 7800 Series - both are trim pieces, not lock bodies. The TownSteel MSE-W is a complete heavy duty Grade 1 mortise lock with lever, wide brass escutcheon, latch bolt, guard bolt, ANSI strike and a brass Classic Visible thumb turn already included.
23) Is the Emtek 3102 Memphis mortise entrance lockset an alternative to the TownSteel MSE-W?
It is not a functional alternative. The Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function, meaning inactive trim with no latching or keying. The TownSteel MSE-W is a keyed single cylinder corridor lock with a 3/4 inch stainless anti-friction split latch bolt and stainless guard bolt, so it is the one that actually secures the opening.
