TownSteel MSE-R-T-06-626 – Frequently Asked Questions

1) What does the holdback function do on the TownSteel MSE Series mortise lock?
Holdback lets you retract the latchbolt and hold it back so the door stays push-open, then release it back to normal latching. It's the function property managers use on laundry rooms, mail rooms, and doors that need to stay free during business hours and lock up after. The MSE is keyed, single cylinder, so the key controls the outside lever and there's a brass thumb turn inside as standard.
2) Do I have to specify handing when ordering a TownSteel MSE mortise lock?
Yes, handing is required. You pick LH, RH, LHR, or RHR. Reverse bevel (LHR/RHR) applies when the door swings out away from you with the hinges on that side, which is common on exterior and stair doors. Get it wrong and the lever and latch bevel face the wrong way.
3) Can I get the TownSteel MSE keyed alike with the other locks in my building?
Keying is a required selection: key different is standard, key alike is offered for running multiple locks on one key, and there's a key code option where you supply the code to match an existing system. If you're standardizing a property on one key, choose key alike or give the key code at order time.
4) Does the TownSteel MSE mortise lock take a small format interchangeable core?
You can order it either as standard cylinder or with SFIC prep, less core. The SFIC version arrives without a core, so a locksmith or facility with its own keying program supplies and pins the core to the existing system. Institutions already running SFIC across a campus usually want that version.
5) What is a comparable Grade 1 mortise lock if I need a storeroom function instead of holdback?
The TownSteel MSE Series mortise lock is built for a holdback function at Grade 1, so it will not give you storeroom operation. For storeroom, the Accentra 8805FL is a Grade 1 mortise lock in the 8800 Series with a storeroom function, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option. The NM8080 is specified for 1-3/4 inch doors.
6) I need a classroom function mortise lock for a school corridor - what should I order instead of the TownSteel MSE?
The MSE Series is a holdback function lock, so it will not meet a classroom spec. Mechanical Grade 1 classroom options include the Corbin Russwin ML2003 in the ML2000 Series and the Cal-Royal NM8070 with auxiliary deadlatch, both specified for 1-3/4 inch doors. If the facility wants keypad credentials instead of keys, the Alarm Lock DL3500CR is a Grade 1 electronic classroom mortise lock for 1-5/8 inch to 1-7/8 inch doors with 300 user codes.
7) Is there a version of this kind of mortise lock with electronic access control instead of a mechanical cylinder?
The TownSteel MSE Series is a mechanical, non-electronic lock that is ready for integration into an access control system. If you want the credential reader built into the lock itself, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock with a keypad reader for 1-3/4 inch doors, the Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad and cylinder override, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. For wired electrified operation, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation.
8) We need privacy function on restrooms - can the MSE Series cover that?
No. The TownSteel MSE Series is a keyed single cylinder lock in a holdback function. For bed and bath privacy, the Cal-Royal NM8440 is a 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 inch to 2 inch doors, which matches the MSE's 2-3/4 inch backset prep.
9) What should I use if the opening is an aluminum storefront rather than a standard mortise prep?
The TownSteel MSE Series is a heavy duty mortise lock with a 1-1/4 inch by 8 inch faceplate and a 2-3/4 inch backset, which suits a standard mortise pocket rather than a narrow storefront stile. For aluminum openings, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is made for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock specified for wide stile doors. For a glass door bottom rail, the Kaba Ilco BR Series is the bottom rail lock.
10) Is the TownSteel MSE mortise lock rated for high traffic commercial doors?
It's an ANSI Grade 1 heavy duty mortise lock built for commercial use, with a stainless steel split anti-friction latchbolt, stainless guard bolt, and stainless rocker-type stop works. Grade 1 is the highest ANSI/BHMA durability tier, which is what schools, hospitals, and multi-family corridors normally spec.
11) What is the difference between the MSE low and regular escutcheon options?
The MSE is escutcheon trim rather than rose trim, and you choose between the low and regular escutcheon profiles. The escutcheon plate itself is brass, 10-9/16 by 2-3/8 by 9/32 inches. Escutcheon trim covers more of the door face, which is useful when you're replacing older trim and want to hide previous prep marks. If you want a compact round trim instead, a rose-trim mortise lock like the Hager 3810S is the other approach.
12) Is the TownSteel MSE an electronic lock, and what if I need access control later?
No, the MSE holdback lock is purely mechanical, no electronics. If the opening needs credentials or audit trail, look at an electrified or standalone mortise instead, such as the Schlage CO-100 standalone electronic mortise with keypad reader, the BEST 45HW wired electromechanical mortise running 12V/24V, or the Command Access ML190 motorized mortise with field selectable EL/EU on 24VDC.
13) What are the Grade 1 mortise alternatives if I need a different function than holdback?
Function is fixed per lock, so pick the body that matches the opening. For a classroom, the Corbin Russwin ML2003 and the Cal-Royal NM8070 are both Grade 1 classroom mortise locks. For storeroom, the Accentra 8805FL or Cal-Royal NM8080, which offers an interchangeable core option. Office/entrance is the Cal-Royal NM8050, and privacy with a deadbolt is the NM8440. Those Cal-Royal bodies are listed for 1-3/4 inch doors.
14) Can the TownSteel MSE be tied into an access control system?
The MSE body is built for single opening, stand-alone use but is ready for integration into access control, and TownSteel offers status sensor options on the platform: REX request-to-exit, PRIV privacy, DAJ door ajar, and MKO mechanical key override. Those monitoring points are what a system integrator needs to report door state back to a panel.
15) The MSE is keyed - what is the equivalent if the opening does not need a cylinder?
The TownSteel MSE Series is a keyed, single cylinder mortise lock. Where no key is required, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors, matching the MSE's 2-3/4 inch backset and escutcheon presentation. The Falcon MA101 is a Grade 1 heavy-duty mortise passage lock 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.
16) What is the difference between the TownSteel MSE and a BEST 45H mortise lock body?
The TownSteel MSE Series ships as a complete heavy duty mortise lock with escutcheon trim, lever, thumb turn and ANSI strike, in a holdback function with a single cylinder. The BEST 45HCAC is a heavy duty mortise lock body in the 45H Series with a public entrance function and field reversible operation, and the BEST 45HCAINL is a heavy duty mortise lockbody with an intruder function. Those are lock bodies, so trim is specified separately, and their functions differ from holdback.
17) Which mortise products look like a substitute for the MSE but are not?
Several mortise-named items are not functional replacements for the TownSteel MSE Series, which is a complete keyed single cylinder lock. The Emtek 3102 Memphis and 3106 Manhattan mortise entrance locksets are dummy function, as is the Schlage L0170 Grade 1 half dummy trim, so none of them latch. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset and no latch operation, and the Sargent 130KB and 130W are mortise thumbturns only. The Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices.
18) For a dormitory or corridor opening, what heavy duty mortise lock compares to the TownSteel MSE?
The TownSteel MSE Series is a heavy duty Grade 1 mortise lock with escutcheon trim and a single cylinder in a holdback function. For a dormitory opening, the Sargent 7925 in the 7900 Series is a heavy duty Grade 1 dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. The trim style is the main visual difference: the Sargent uses a rose while the MSE uses a 10-9/16 inch by 2-3/8 inch brass escutcheon.
19) Our doors are thicker than 1-3/4 inches - which mortise locks are rated past that?
Among comparable mortise locks, the Hager 3810E and 3810S passage locks are specified for 1-3/4 inch to 2-1/2 inch doors and the Hager 3850E office lock covers the same 1-3/4 inch to 2-1/2 inch range, all with a 2-3/4 inch backset that matches the TownSteel MSE Series prep. The Baldwin 6301 entry/apartment mortise lock bodies are listed for 1-3/4 inch and over, though they use a 2-1/2 inch backset rather than 2-3/4 inches.
20) The MSE takes an SFIC prep - which other mortise locks accept an interchangeable core?
The TownSteel MSE Series can be ordered with an SFIC prep less core or with a standard cylinder. Among comparable mechanical mortise locksets, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset offered with an interchangeable core option for 1-3/4 inch doors. If you are standardizing a facility on one core system, that keeps the keying consistent across both storeroom and holdback openings.
21) Is there an ADA push/pull alternative to a lever mortise lock for a healthcare corridor?
The TownSteel MSE Series uses lever trim, with lever styles including Artistic, Gala, Imperial, Quest, Regal, Sentinel and Tango. Where a facility wants no lever at all, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in the 195 Series, described as ligature resistant and ADA compliant in satin stainless steel. It is a passage function, so it does not key like the MSE single cylinder.
22) We need a fire rated mortise lock - which comparable options state a rating?
Among comparable mortise products, the Falcon MA101 Grade 1 heavy-duty passage mortise lock carries a fire rating, and the Schlage Electronics LEMD-GRW Grade 1 ENGAGE Series wireless mortise lock states a 3 hour fire rating, as does the Schlage LEBMB-ADD Grade 2 mobile-enabled mortise lock. The TownSteel MSE Series is a Grade 1 heavy duty commercial mortise lock; confirm the opening's fire requirement against the door and frame label before selecting trim.
23) What finishes and lever styles can I get on the TownSteel MSE mortise lock?
Seven finishes: 605 bright brass, 606 satin brass, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless, and 630 satin stainless. Eight lever designs: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel, and Tango. Levers are forged brass or cast zinc plated to match the finish symbol, so trim across a floor stays consistent. 626 satin chrome and 630 satin stainless are the usual commercial matches.
