TownSteel MSE-R-T-05-626 – Frequently Asked Questions

1) What backset and faceplate does the TownSteel MSE Series mortise lock use, and will it drop into an existing ANSI mortise pocket?
The MSE Series mortise lock is built on a 2-3/4 inch backset with a 1-1/4 x 8 inch stainless steel faceplate, which is the standard ANSI mortise prep dimension, and it ships with an ANSI strike in plated or stainless steel. If the door already has a 2-3/4 inch backset mortise pocket cut for a 1-1/4 x 8 inch face, the lock body drops in. What you still need to verify is the escutcheon cutout, since the trim measures 10-9/16 x 2-3/8 x 9/32 inches in brass and covers more of the door face than a rose trim lock.
2) Will the TownSteel MSE classroom mortise lock latch into a strike already in my frame?
The latch bolt throws 3/4 inch and is a stainless steel split, anti-friction design, with a separate stainless guard bolt that deadlocks it when the door closes. A 3/4 inch throw is what ANSI mortise strikes are cut for, so an existing ANSI strike pocket will take it. An ANSI strike is supplied with the lock, so if your frame prep matches the ANSI cutout you can use the new one.
3) How does a classroom function mortise lock actually work on the door?
Classroom function means the outside lever is locked and unlocked by key only, and the inside lever always retracts the latch for free egress. Nobody can lock or unlock the door from the corridor side without the key, and nobody gets trapped inside. The MSE Series version is single cylinder, so there is one keyed cylinder outside and a thumb turn on the inside, supplied in brass with the Classic Visible style as standard.
4) Do I have to specify handing when ordering the TownSteel MSE mortise lock?
Yes, handing is a required selection. Four options are offered: LH (left hand), RH (right hand), LHR (left hand reverse), and RHR (right hand reverse). Stand outside the opening on the key side: if the hinges are on your left it is left hand, on the right it is right hand, and if the door swings toward you it is the reverse version. Get this wrong and the lever and latch face the wrong way.
5) Can I get the TownSteel MSE mortise locks keyed alike across a building?
Keying is a required choice at order time. Key different is the standard, key alike is available when you want one key to run multiple locks on a floor or a building, and there is a special keying option where you supply the key code. If you are standardizing a school or office suite on one key system, choose key alike and order the whole group together.
6) Does the MSE Series mortise lock take small format interchangeable cores?
Two cylinder builds are offered: standard cylinder, or SFIC prep less core. The SFIC version arrives prepped but without a core, so a locksmith or facility can drop in cores from the site's existing small format system and keep the building on one key platform. Order cores separately if you go that route.
7) If the school wants keypad access instead of a key on the classroom door, what mortise lock should be used?
The TownSteel MSE Series is a mechanical, non-electronic keyed mortise lock, so access is by key only. For electronic classroom control, the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 classroom-function electronic mortise lock with a weatherproof design for 1-5/8 to 1-7/8 inch doors, and the Alarm Lock DL3500CR is a Grade 1 classroom-function electronic mortise lock carrying 300 user codes on the same door thickness range. Choose those when codes rather than cut keys will manage the opening.
8) Is the TownSteel MSE mortise lock rated for high traffic commercial openings?
It is a Grade 1, heavy duty commercial mortise lock, which is the top ANSI/BHMA durability tier and the usual specification for schools, hospitals, and other high-use openings. The internals back that up: stainless steel latch bolt, guard bolt, faceplate and rocker type stop works, with a brass escutcheon and forged brass or cast zinc levers plated to match the finish.
9) What lever styles and finishes can I get so the MSE locks match the rest of my doors?
Eight lever designs are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel, and Tango. Finishes run 605 bright brass, 606 satin brass, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless, and 630 satin stainless. Levers are forged brass or cast zinc plated to match the finish symbol, so trim across a set of openings will read consistently. Note that not every lever and finish pairing is necessarily built together, so match the combination to what you already have on site.
10) What are the alternatives to the TownSteel MSE classroom mortise lock from other brands?
Two close mechanical equivalents we carry: the Cal-Royal NM8070, a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch listed for 1-3/4 inch doors, and the Corbin Russwin ML2003 from the ML2000 Series, a Grade 1 mortise classroom lockset also listed at 1-3/4 inch door thickness. Both are rose or standard trim products rather than the full escutcheon look. If you want classroom control without cutting keys for every teacher, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with classroom function and 300 user codes, for 1-5/8 to 1-7/8 inch doors.
11) Is the TownSteel MSE mortise lock an electronic or access control lock?
No. The MSE Series is a mechanical, key operated mortise lock, not an electrified one. If the opening needs credential or card access, look at an electromechanical mortise lock instead, such as the BEST 45HW wired heavy duty mortise lock with 12V/24V operation or the Schlage Electronics LEMD-GRW Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader.
12) I need a storeroom or privacy lock instead of classroom for some doors in the same building. What should I order?
The MSE lock described here is classroom function only, so for other openings pick the function that matches use. For a storeroom door that always stays locked outside, the Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series. For restrooms and bedrooms, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt. The Cal-Royal units are listed for 1-3/4 inch doors.
13) Which mortise lock should be used on a restroom or bedroom instead of the TownSteel MSE classroom lock?
The TownSteel MSE Series is a keyed single-cylinder classroom lock, not a privacy set. For bed and bath openings, 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 of the 3800 Series is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors, matching the 2-3/4 inch backset the MSE uses.
14) Is a Sargent 130KB thumbturn a substitute for the TownSteel MSE classroom mortise lock?
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, both of which are trim pieces only. The TownSteel MSE Series is a complete Grade 1 heavy duty mortise lock with lock body, escutcheon trim, ANSI strike and a 3/4 inch stainless steel latch bolt. Order a thumbturn only when replacing that single component on an existing lock.
15) What is a simpler non-keyed mortise lock for corridor or closet doors that do not need the TownSteel MSE classroom keying?
Where no key control is needed, the Falcon MA101 of the MA Series is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Schlage PM010 of the PM Series is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Hager 3810E is a Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset. The TownSteel MSE Series by contrast is a keyed lock with a single cylinder.
16) The MSE classroom lock uses escutcheon trim. What mortise lock is available with rose trim instead?
The TownSteel MSE Series uses a brass escutcheon measuring 10-9/16 by 2-3/8 by 9/32 inches, offered in low and regular escutcheon styles. If the opening calls for rose trim, the Hager 3810S of the 3800 Series is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset, and the Sargent 7925 of the 7900 Series is a Grade 1 heavy duty corridor/dormitory mortise lock with rose trim and a single cylinder deadbolt.
17) Can an access-control mortise lock replace the TownSteel MSE classroom lock on the same opening?
The TownSteel MSE Series is a mechanical lock designed for single-opening, stand-alone use and prepared for integration into access control systems. If the electrified lock body itself is wanted, the Command Access ML190 Series is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation at 24VDC, and the BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V. Both require power to the door, which the MSE does not.
18) Will an Emtek mortise entrance lockset work in place of the TownSteel MSE classroom mortise lock?
No. The Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, meaning they do not latch or lock. The TownSteel MSE Series is a commercial Grade 1 keyed classroom mortise lock with a 3/4 inch anti-friction stainless steel latch bolt and guard bolt. Use a dummy set only on an inactive leaf.
19) For a 2-1/2 inch backset residential-style mortise body, what is used instead of the TownSteel MSE?
The TownSteel MSE Series is built on a 2-3/4 inch backset with a 1-1/4 by 8 inch stainless steel faceplate. For openings prepped to a 2-1/2 inch backset, the Baldwin 6301LS is an entry/apartment lever by lever mortise lock body for doors 1-3/4 inch and over, and the Baldwin 6310 is an entry/storeroom knob by knob mortise lock body for doors 1-3/8 inch and over. Confirm the existing mortise pocket before ordering either.
20) If the door needs a deadbolt only rather than a latching classroom lock, what mortise option applies?
The TownSteel MSE Series is a latching classroom lockset with a 3/4 inch latch bolt and guard bolt. For deadbolt-only openings, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, matching the MSE backset, and the Kaba Ilco 185 Series is a no-handing deadbolt-function mortise lock. Neither provides lever operation.
21) The MSE is ordered with SFIC prep. Which comparable mortise locks also take an interchangeable core?
The TownSteel MSE Series classroom lock can be ordered with SFIC prep less core or with a standard cylinder. Among comparable mechanical mortise locksets, the Cal-Royal NM8080 Grade 1 storeroom lockset is offered with an interchangeable core option, and the BEST 45H Series heavy duty mortise lock body is a public entrance function body from a line built around interchangeable core keying. Match your facility's existing core system when standardizing.
22) What is the difference between the MSE low and regular escutcheon options?
The escutcheon axis offers MSE Low and MSE Regular. Both are the full plate style trim rather than a round rose, with the brass escutcheon measuring 10-9/16 x 2-3/8 x 9/32 inches. Pick the profile that matches the trim already on your adjacent openings, since escutcheon trim covers a larger footprint of the door face than rose trim and a mismatch is visible from across the corridor.
23) Is there a template for prepping the door for the TownSteel MSE mortise lock?
Yes. TownSteel publishes the MSS template for this mortise prep, linked from the product information, and it gives the pocket, cross bore, and trim hole layout the installer needs before routing. Prep to that template with the 2-3/4 inch backset and the 1-1/4 x 8 inch faceplate, and confirm your handing selection before cutting.
