TownSteel MSE-R-T-30-626 – Frequently Asked Questions

1) What does the double cylinder function on the TownSteel MSE mortise lock actually do on the door?
Double cylinder means a keyed cylinder on both sides of the opening, so the lever is controlled by key from inside and outside. TownSteel calls this the institutional function (asylum, institution and utility use), which is why it shows up on doors where staff need to control passage in both directions rather than allow free egress. If you need free egress from inside, this is the wrong function: a storeroom or classroom lock such as the Cal-Royal NM8080 storeroom or NM8070 classroom mortise lockset is what you want instead.
2) Will the MSE mortise lock drop into an existing 2-3/4 inch backset mortise prep?
Yes on the backset: the MSE lock body uses a 2-3/4 inch backset, the standard commercial mortise backset, with a 1-1/4 by 8 inch stainless steel faceplate. The latch bolt projects 3/4 inch and is a split, anti-friction stainless design, and an ANSI strike in plated or stainless steel is part of the set, so if your frame already has an ANSI strike prep the latch lines up. TownSteel publishes the MSS template for the pocket and trim through-bolt layout, so check your existing mortise against that before cutting.
3) What do I have to specify when ordering a TownSteel MSE escutcheon mortise lock?
Four things beyond the basic lock. Handing is required: LH, RH, LHR or RHR. Keying is required: key different (standard), key alike for multiple locks, or a special key code, and if you pick key code you enter that code with the order. You also choose the cylinder as standard or SFIC prep less core, and the escutcheon as MSE low or MSE regular. Lever style comes from eight options: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango.
4) Can I key these TownSteel mortise locks into my building's existing small format interchangeable core system?
Order the SFIC prep, less core version and you install your own small format interchangeable cores, so the lock joins whatever SFIC keyway your facility already runs. If you are not on an SFIC system, take the standard cylinder version and order it key alike across multiple locks, or supply a key code for special keying. Key different is the default.
5) Is the TownSteel MSE mortise lock electronic or can it be tied into access control?
The MSE escutcheon lock itself is a mechanical, non-electronic lock. TownSteel's MS motorized mortise platform is what handles stand-alone or access-control-integrated openings, with optional status sensors for request-to-exit, privacy, door ajar and mechanical key override. If your project needs a credential reader or wired electric control at the lock, look at an electrified mortise such as the BEST 45HW wired electromechanical mortise lock with 12V/24V operation or the Command Access ML190 Series motorized mortise with field selectable EL/EU operation on 24VDC.
6) What is the closest Grade 1 mortise storeroom lock to the TownSteel MSE if the opening does not need a double cylinder?
The MSE Series is a Grade 1 heavy duty mortise lock built in a double cylinder keyed function, so it takes a key on both sides. For an opening that only needs key entry from the outside with free egress, the Accentra 8805FL is a Grade 1 storeroom function mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors.
7) I need a classroom function mortise lock instead of the TownSteel MSE double cylinder - what should I order?
The MSE Series is keyed as a double cylinder institutional function lock. For classroom function on a mortise prep, the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors in the ML2000 Series, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors.
8) If I want keypad or credential access on the same mortise prep instead of the TownSteel MSE, what are the options?
The MSE Series is a mechanical lock with no electronics. For access control on a mortise prep, the Schlage CO-100-MS-40-KP is a Grade 1 standalone electronic mortise lock with a keypad reader for 1-3/4 inch doors, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes in classroom function, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader.
9) For a behavioral health or ligature-resistant opening, is the TownSteel MSE the right choice or is there a better fit?
The MSE Series is a Grade 1 heavy duty mortise lock in an asylum, institution and utility function with escutcheon trim and a double cylinder. Where the opening calls for a push/pull rather than a lever, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset described as ligature resistant and ADA compliant in satin stainless steel - though it is passage function, so it does not key.
10) Is the TownSteel MSE lock heavy duty enough for a hospital or correctional corridor?
It is an ANSI Grade 1 heavy duty mortise lock built for commercial use, with a stainless steel latch bolt, stainless guard bolt, stainless faceplate and stainless rocker-type stop works. Grade 1 is the highest ANSI/BHMA operational grade, which is the level institutional and MRO specs normally call for on high-traffic openings. The lever is forged brass or cast zinc plated to match the finish, and the escutcheon is brass.
11) How big is the escutcheon plate on the TownSteel MSE lock, and will it fit a narrow door stile?
The MSE escutcheon measures 10-9/16 x 2-3/8 x 9/32 inches in brass. At 2-3/8 inches across the plate, you need a stile that accommodates that width plus edge clearance, so it suits wide stile wood and hollow metal doors rather than narrow aluminum stiles. Two heights are offered, MSE low and MSE regular. If you are working on an aluminum storefront bottom rail instead, that is a different animal, a Kaba Ilco BR Series glass door bottom rail lock.
12) How do I determine handing for the TownSteel MSE mortise lock, and is it field reversible?
Handing must be specified at order: left hand, right hand, left hand reverse or right hand reverse. Reverse means the door swings out toward you from the secure side. Stand outside the opening, note which side the hinges are on and which way the leaf swings, then pick from those four. If you need a lock you can flip on site instead, a field reversible body like the BEST 45H Series public entrance mortise lock body or the Falcon MA101 passage mortise lock covers that.
13) What are the alternatives to the TownSteel MSE double cylinder lock if I need a thumbturn or privacy instead of a second key?
The MSE set includes a brass thumb turn, classic visible style as standard, but the keyed function is double cylinder, so the outside and inside are both key controlled. Where you want occupant privacy rather than key control on the inside, a Grade 1 privacy mortise lockset such as the Cal-Royal NM8440 with deadbolt or the Hager 3840S covers that. For a double keyed deadbolt only, without a latch and lever, the Sargent 4874 double cylinder mortise deadbolt uses the same 2-3/4 inch backset.
14) Should I use a mortise lock like the TownSteel MSE or a cylindrical lock on an institutional door?
A mortise lock like the MSE requires a machined pocket in the door edge and gives you a heavy duty Grade 1 body with a guard bolt, anti-friction latch and full escutcheon trim, which is what institutional and high-abuse openings usually get specified. A cylindrical lock bores through the face of the door instead, which is faster to install and cheaper to retrofit, for example the Schlage PC10 Grade 1 passage cylindrical lock. If the door is already mortise prepped, stay with mortise. Converting a bored door to mortise means replacing or heavily modifying the leaf.
15) Does the TownSteel MSE mortise lock come with a strike, or do I order that separately?
An ANSI strike in plated or stainless steel comes as part of the MSE lock. The latch bolt throws 3/4 inch into it and is a split anti-friction type, with a separate stainless guard bolt that deadlocks the latch when the door is closed. Cylinders are the item to watch: if you order the SFIC prep version, it arrives less core and you supply the cores.
16) Is there an escutcheon-trim mortise lock alternative to the TownSteel MSE for a non-keyed opening?
The MSE Series is a keyed double cylinder lock with escutcheon trim and a 2-3/4 inch backset. If the opening is non-keyed, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the Hager 3850E is an office function mortise lock with lever and escutcheon, non-keyed, on the same 2-3/4 inch backset.
17) Can a Sargent 4874 replace the TownSteel MSE double cylinder mortise lock?
Not as a one-for-one. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset - it is deadbolt only, with no lever or latch. The MSE Series is a complete heavy duty lockset with escutcheon trim, a 3/4 inch anti-friction latch bolt, guard bolt and levers, on the same 2-3/4 inch backset. Use the 4874 where you only need the bolt.
18) What looks like a substitute for the TownSteel MSE mortise lock but will not work?
Several mortise-named parts are not locksets. The Sargent 130KB and 130W are mortise thumbturns only, the Schlage L0170 is half dummy trim with no latching function, and the Emtek 3102 Memphis and 3104 Hamilton are dummy mortise entrance locksets. The Schlage PC10 is a cylindrical passage lock, which needs a bored prep rather than the mortise pocket the MSE Series requires.
19) I need a privacy mortise lock rather than the TownSteel MSE double cylinder - what is comparable?
The MSE Series keys from both sides as a double cylinder lock, which is not a privacy arrangement. For 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 on a 2-3/4 inch backset for 1-3/4 to 2 inch doors - the same backset the MSE Series uses.
20) Can I order just a mortise lock body instead of the complete TownSteel MSE lockset?
The MSE Series ships as a complete lockset with escutcheon trim, levers and a thumb turn. If you only need the body because trim is already on the door, the BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody with intruder function.
21) Does the TownSteel MSE work on a 1 inch ornamental iron door, or is there a double cylinder lock made for that?
For narrow ornamental iron doors, the Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, both listed for 1 inch door thickness. The TownSteel MSE Series is a heavy duty commercial escutcheon lockset with a 10-9/16 inch by 2-3/8 inch brass escutcheon and a 1-1/4 inch by 8 inch faceplate, which is sized for standard commercial door stiles rather than narrow iron work.
22) What is an alternative to the TownSteel MSE for a dormitory or corridor opening with a deadbolt?
The MSE Series is a double cylinder institutional function lock with escutcheon trim. For a dormitory opening, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt in the 7900 Series - rose rather than escutcheon, so confirm the trim prep on the door.
23) The TownSteel MSE can be ordered SFIC prep less core - which comparable locks also take an interchangeable core?
The MSE Series is offered with an SFIC prep less core as well as a standard cylinder arrangement. Among comparable mortise locksets, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset is listed with an interchangeable core option, which lets it join the same core keying system on a 1-3/4 inch door.
24) Which finishes does the TownSteel MSE mortise lock come in for matching other hardware in a building?
Seven finishes, by BHMA number: 605 bright brass, 606 satin brass, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. Levers are plated to match the finish symbol, so trim and escutcheon read consistently. For commercial corridors 626 satin chrome and 630 satin stainless are the usual standards to match existing openings.
