TownSteel MSE-W-T-04-626 – Frequently Asked Questions

1) What backset and faceplate size does the TownSteel MSE-W mortise lock use?
The MSE-W mortise lock body is a 2-3/4 inch backset unit with a 1-1/4 by 8 inch stainless steel faceplate. That is the standard commercial mortise prep, so if the door is already mortised for a 2-3/4 inch backset lock with an 8 inch face, the body drops into the same pocket. The wide escutcheon trim measures 10-9/16 x 2-3/8 x 9/32 inches in brass, so it needs a stile wide enough to take a 2-3/8 inch plate.
2) Will the TownSteel MSE-W latch into my existing ANSI mortise strike?
It should. The lock ships with a plated or stainless steel ANSI strike and uses a 3/4 inch projection stainless steel latch bolt, split and anti-friction, plus a stainless guard bolt. A frame already prepped for an ANSI 4-7/8 inch mortise strike takes it without new frame work, and the 3/4 inch throw is the standard mortise latch engagement.
3) What does entry/office function mean on this TownSteel mortise lock, and is it the right one for a tenant office door?
Entrance/office function means the outside lever is locked or unlocked by key, and by the inside thumb turn, while the inside lever always retracts the latch for free egress. That is the usual choice for a tenant suite or office door that staff want to leave unlocked through the day and secure on the way out. If you need a door that stays locked at all times and is only opened by key from outside, order a storeroom function instead, such as the Cal-Royal NM8080.
4) Do I have to specify handing when I order the MSE-W mortise lock?
Yes, handing is a required selection. The four choices are LH (left hand), RH (right hand), LHR (left hand reverse) and RHR (right hand reverse). Stand outside the door, on the side that keys: hinges on your left is left hand, and if the door swings toward you it is the reverse version. Get this wrong and the lever and stop works will be oriented for the wrong swing. If you would rather not hand-specify, a field reversible body like the BEST 45H is an alternative approach.
5) Can I get the TownSteel MSE-W prepped for small format interchangeable core?
Yes. The cylinder choice is either Standard or SFIC Prep, Less Core. SFIC prep ships without a core, so you supply your own 6 or 7 pin SFIC in the keyway your facility already runs. That is the option to pick if a locksmith maintains your master key system in house. Pick Standard if you want the lock keyed and ready to hang.
6) Can I order several of these TownSteel mortise locks keyed alike for one building?
Yes. Keying is a required selection with three choices: KD keyed different, which is the standard, KA keyed alike when you want one key to run multiple locks, and Key Code for special keying, where you type the code into the key code field on the order. Property managers standardizing a floor or a common area usually take KA; a master keyed system typically goes SFIC prep and gets cored locally.
7) What is the closest cross-brand equivalent to the TownSteel MSE-W entry/office mortise lock?
The Cal-Royal NM8050 is the nearest match: a heavy duty Grade 1 mortise lockset with an Entrance/Office function, rated for 1-3/4 inch doors. The TownSteel MSE-W is also a Grade 1 heavy duty mortise lock in an Entrance/Office function, with a 2-3/4 inch backset and a wide brass escutcheon trim measuring 10-9/16 by 2-3/8 inches. The main difference a buyer notices on the door is trim style: the MSE-W is an escutcheon-trim lock offered in Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango lever designs in 626 satin chrome.
8) I need a mortise lock that always stays locked outside instead of an office function - what should I order?
For an always-locked exterior opening, a storeroom function is the right call rather than an entry/office lock like the TownSteel MSE-W, which is an Entrance/Office function single cylinder lock. 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 heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. Storeroom trim keeps the outside lever locked at all times with key entry only, while the MSE-W office function allows the outside lever to be left unlocked by the thumb turn.
9) I need privacy for a restroom - is the TownSteel MSE-W the right lock?
No. The MSE-W is a keyed single cylinder entrance/office lock, which is not a privacy function. For a bed, bath or restroom opening use a privacy body: 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 with a 2-3/4 inch backset for 1-3/4 to 2 inch doors, which matches the MSE-W backset.
10) Will a Baldwin 6301 mortise lock body drop into the same prep as the TownSteel MSE-W?
Not directly. The Baldwin 6301 entry/apartment mortise lock body is a 2-1/2 inch backset lock, offered knob by knob or lever by lever for doors 1-3/4 inch and over. The TownSteel MSE-W uses a 2-3/4 inch backset with a 1-1/4 by 8 inch stainless faceplate and an ANSI strike, so the cylinder and spindle centerlines land in different places. If you are replacing an existing 2-3/4 inch backset commercial mortise prep, stay with the MSE-W or another 2-3/4 inch backset body such as the Hager 3850E office mortise lock with lever and escutcheon.
11) Can I order the TownSteel MSE-W with a small format interchangeable core to match my keying system, or do I need another brand?
You can order it as-is. The TownSteel MSE-W is offered in a standard cylinder configuration or as SFIC prep less core, so an SFIC house can drop in its own core across every lever style, including Artistic, Gala, Imperial and Sentinel in 626 satin chrome, and keying is selectable key different, key alike or to a supplied key code. Among comparable mortise locks, the Cal-Royal NM8080 storeroom lockset also offers an interchangeable core option, but that body is a storeroom function rather than entrance/office.
12) Is the TownSteel MSE-W tough enough for a high traffic commercial entry?
It is built for it. The MSE Series is an ANSI Grade 1 heavy duty mortise lock rated commercial, with a stainless steel latch bolt, guard bolt, faceplate and rocker type stop works, and a brass escutcheon. Grade 1 is the highest ANSI/BHMA durability tier and the one normally specified for building entrances, schools and healthcare corridors. Levers are forged brass or cast zinc plated to match the finish.
13) Is this TownSteel mortise lock electronic or does it need any wiring?
It is a purely mechanical, keyed mortise lock, no power and no wiring. If your opening needs access control, card or keypad credentials, look at an electrified mortise instead, such as the BEST 45HW wired electromechanical mortise lock running 12V or 24V, or the Schlage CO-100 standalone keypad mortise lock.
14) Should I pick a wide escutcheon mortise lock or a rose trim version?
Escutcheon trim like the MSE-W covers a tall, narrow plate area, 10-9/16 by 2-3/8 inches here, which hides old prep scars and gives a more finished look on a flush commercial door. Rose trim is two small round plates and is the leaner choice on doors with tight glass or narrow lite framing where a full escutcheon would crowd the stile. Among comparable Grade 1 mortise locks, Hager offers the same function both ways, the 3810E with escutcheon and the 3810S with rose, if you want to see the difference.
15) What is an equivalent entrance/office mortise lock if the TownSteel MSE-W is not the right fit?
The closest match by function is the Cal-Royal NM8050, a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. If the door needs a non-keyed lever on the office side, the Hager 3850E is a Grade 1 office mortise lock with escutcheon and a 2-3/4 inch backset, so it shares the MSE-W prep. For classroom function on the same kind of opening, the Corbin Russwin ML2003 covers it.
16) Does the TownSteel MSE-W have a deadbolt?
No. It is a single cylinder entrance/office lock with a 3/4 inch latch bolt and a stainless guard bolt (the auxiliary deadlatch that blocks the latch from being carded), not a deadbolt. If the opening needs a separate throw bolt, look at a privacy/deadbolt mortise such as the Cal-Royal NM8440, or a dedicated mortise deadbolt like the Sargent 4874 double cylinder unit on a 2-3/4 inch backset.
17) Is there a keyless mortise lock I can use on a door that does not need a cylinder?
Yes. The TownSteel MSE-W is keyed with a single cylinder, so if the opening does not need a key, look at a non-keyed mortise body instead. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset covering 1-3/4 to 2-1/2 inch doors, which keeps the same backset and escutcheon look as the MSE-W. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating.
18) What is the difference between the TownSteel MSE-W escutcheon lock and a rose-trim mortise lock?
Trim coverage. The MSE-W uses a wide brass escutcheon plate measuring 10-9/16 inches by 2-3/8 inches by 9/32 inch that covers the cylinder, lever and thumb turn on one plate. A rose-trim lock uses separate small round plates instead: the Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset, and the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. Escutcheon trim is the choice when you want to cover existing prep marks or match a plate-trim look on adjacent doors.
19) Can I use an electronic mortise lock in place of the TownSteel MSE-W for access control?
Yes, if you want credentials at the door rather than a key. The MSE-W is a non-electronic mechanical mortise lock that is keyed single cylinder and is built to be integrated into an access control system with optional status sensors including REX, privacy, door ajar and mechanical key override. If you would rather the lock itself carry the reader, the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader for 1-3/4 inch doors, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V for hardwired systems.
20) Is an Emtek 3102 Memphis mortise entrance lockset a substitute for the TownSteel MSE-W?
No, despite the similar-sounding name. The Emtek 3102 Memphis mortise entrance lockset is a dummy function, meaning it has no latch or locking action and is used on inactive leaves. The TownSteel MSE-W is a keyed single cylinder entrance/office lock with a 3/4 inch projection stainless steel split anti-friction latch bolt, a stainless guard bolt and rocker type stop works. The same applies to the Emtek 3104 Hamilton and 3106 Manhattan, which are also dummy function.
21) What should I use instead of the TownSteel MSE-W on a narrow aluminum storefront door?
The MSE-W carries a wide escutcheon trim 2-3/8 inches across with a 2-3/4 inch backset, which is sized for a wide stile or hollow metal door rather than a narrow aluminum stile. For aluminum storefront, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is built for Adams Rite deadlatches, and the Dormakaba E-Plex E2066 is an electronic pushbutton keyless mortise lock listed for wide stile applications. For a glass door bottom rail, the Kaba Ilco BR Series is the bottom rail lock for that application.
22) Is the TownSteel MSE-W a complete lockset or just a lock body like the BEST 45H?
The MSE-W is supplied as a complete trimmed lockset: mortise body with a 3/4 inch stainless split anti-friction latch bolt, ANSI plated or stainless strike, 1-1/4 by 8 inch stainless faceplate, brass escutcheon trim, forged brass or cast zinc levers plated to match the finish, and a brass classic visible thumb turn. By contrast the BEST 45HCAC is a heavy duty mortise lock body in the public entrance function with field reversible operation, and the BEST 45HCAINL is a heavy duty mortise lockbody with intruder function, both of which are bodies you trim separately. The Sargent 130KB and 130W are thumbturns only.
23) I only need a deadbolt on the door, not a latch - what mortise option fits?
Then the MSE-W is more lock than you need; it is a latching entrance/office lockset with lever trim. For deadbolt only, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which matches the MSE-W backset dimension, and the Kaba Ilco 185 Series mortise lock is a deadbolt function supplied with no handing. If you want a keypad deadbolt, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 to 1-7/8 inch doors.
24) What lever styles and finish does the TownSteel MSE-W come in?
Seven lever designs are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango, each available with either a standard cylinder or SFIC prep. Finish is 626 satin chrome, which is the common commercial finish and matches most existing 626 hardware in an office or institutional building, so the levers and escutcheon will sit consistently alongside closers, exit devices and pulls already in that finish.
25) Is there a template for mortising the door for the TownSteel MSE Series lock?
Yes, TownSteel publishes the MSS template for the mortise pocket and trim prep, linked from the product information, and the body is cut for a 2-3/4 inch backset with a 1-1/4 by 8 inch faceplate. Fabricate or route the door to that template before the lock arrives and the install is a drop-in.
