TownSteel MSE-W-T-31-626 – Frequently Asked Questions

1) What does the exit function do on the TownSteel MSE-W mortise lock, and is there a key cylinder?
The MSE-W exit function is non-keyed. The inside lever always retracts the latch for free egress, and there is no key cylinder in this configuration; a brass thumb turn (Classic Visible style is standard) handles locking of the outside lever. If you need key control from the corridor side, this is the wrong configuration and you want a keyed mortise function such as storeroom or classroom instead.
2) What backset and latch throw does the TownSteel MSE-W mortise lock use, and will it hit my existing ANSI strike?
It's a 2-3/4 inch backset mortise body with a 3/4 inch stainless steel latch projection, split and anti-friction, plus a stainless guard bolt. That's the standard commercial mortise geometry, so it lines up with an existing ANSI-prepped frame; an ANSI strike in plated or stainless steel is part of the package.
3) Do I have to specify handing when ordering a TownSteel MSE-W mortise lock?
Yes, handing is a required selection. Choose LH (left hand), RH (right hand), LHR (left hand reverse), or RHR (right hand reverse). Reverse hands are for doors that swing out toward you from the secure side, which is common on exterior and stairwell openings. Get this wrong and the lever and latch orientation will be backwards on the opening.
4) I need the same heavy duty mortise body but with a key on the outside - what takes the place of the TownSteel MSE-W?
Move to a keyed function mortise lock. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. For a keyed classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors. The TownSteel MSE-W is a non-keyed exit function, so none of the outside key control those provide is present on it.
5) What is the closest equivalent to the TownSteel MSE-W exit function mortise lock from another manufacturer?
For an exit-function heavy duty Grade 1 mortise lock, the Sargent 7925 is the nearest peer: it is a heavy duty Grade 1 mortise lock listed with a corridor/dormitory exit function. The difference is trim style and keying - the TownSteel MSE-W is a non-keyed wide escutcheon lock in a Grade 1 heavy duty mortise body, while the Sargent 7925 uses rose trim and includes a single cylinder deadbolt. If the opening needs a cylinder and deadbolt at the exit function, the 7925 matches; if you want escutcheon trim with no key, the MSE-W does.
6) If the opening only needs free passage rather than an exit function, what mortise lock should I use instead of the TownSteel MSE-W?
Use a dedicated passage mortise lock. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset, which matches the escutcheon look and the 2-3/4 inch backset of the TownSteel MSE-W. The Falcon MA101 is another option - a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Schlage's PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. Any of these latch and retract from both sides with no locking at all, where the MSE-W carries an exit function.
7) How much door face does the wide escutcheon on the TownSteel MSE-W cover?
The escutcheon plate measures 10-9/16 x 2-3/8 x 9/32 inches and is brass, plated to the finish. The mortise faceplate is 1-1/4 by 8 inches in stainless steel. If you're replacing an older lock, that escutcheon footprint is what determines whether old trim screw holes and prep scars get covered.
8) Which lever styles and finish can I get on the TownSteel MSE-W escutcheon mortise lock?
Eight lever designs are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel, and Tango, all in 626 satin chrome. Levers are forged brass or cast zinc, plated to match the finish symbol, so they blend with other 626 hardware already on the building.
9) Is the TownSteel MSE-W heavy enough for a high-traffic commercial corridor?
It's a commercial, heavy duty, ANSI Grade 1 mortise lock, which is the top durability tier for cycle life and strength and the usual spec for schools, hospitals, and multi-family corridors. Stainless steel latch, guard bolt, faceplate, and rocker-type stop works back that up.
10) Is the TownSteel MSE-W an electronic or access control lock?
No. The MSE-W is a mechanical mortise lock, not electrified. If you need a card reader, keypad, or wired access control on the same opening, look at an electronic mortise lock such as the BEST 45HW wired electromechanical mortise lock with 12V/24V operation, or the Dormakaba E-Plex 2066 pushbutton keyless mortise lock.
11) What is the difference between the TownSteel MSE-W wide escutcheon lock and a rose trim mortise lock like the Hager 3810S?
It is the trim footprint on the door face. The TownSteel MSE-W uses a wide brass escutcheon measuring 10-9/16 by 2-3/8 by 9/32 inches, which covers a tall section of the stile. The Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset - a round plate at the lever only. Escutcheon trim is the choice when you are covering previous prep or want the wide-plate look across a set of doors; rose trim leaves more of the door visible. Note the 3810S is a passage function while the MSE-W is an exit function.
12) Is the Schlage L0170 a substitute for the TownSteel MSE-W non-keyed mortise lock?
No. Both are non-keyed Grade 1 heavy duty mortise products, but the Schlage L0170 is a half dummy trim - a lever that is fixed and operates no latch. The TownSteel MSE-W is a working exit function mortise lock with a 3/4 inch projection stainless steel anti-friction latch bolt, guard bolt and ANSI strike. Use the L0170 only on an inactive leaf or pull-side application, not where the door has to latch.
13) We want keypad or credential access on this opening - what replaces the mechanical TownSteel MSE-W?
The MSE-W is a mechanical, non-electronic mortise lock, so you would change platforms. Grade 1 electronic mortise options include the Alarm Lock DL3500CR Trilogy with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, the Schlage CO-100 standalone electronic mortise lock with keypad reader on a Grade 1 heavy duty body for 1-3/4 inch doors, and the Schlage LEMD-GRW Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader. Check the door thickness against your leaf before you commit, since those ranges differ.
14) For a bathroom or bedroom door, should I use the TownSteel MSE-W or a privacy mortise lock?
Use a privacy function. 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 is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors, matching the MSE-W's 2-3/4 inch backset. Those give the inside occupant a locking thumbturn dedicated to privacy; the TownSteel MSE-W is configured as an exit function instead.
15) Can I use a Baldwin 6301LS mortise lock body in place of the TownSteel MSE-W?
Not without changing the door prep. The Baldwin 6301 lever by lever is an entry/apartment mortise lock body on a 2-1/2 inch backset for doors 1-3/4 inch and over, while the TownSteel MSE-W is built on a 2-3/4 inch backset with a 1-1/4 by 8 inch stainless faceplate. A quarter-inch backset difference moves the lever centerline relative to the door edge, so the two are not drop-in interchangeable, and the functions differ as well.
16) What should I specify instead of the TownSteel MSE-W for a behavioral health or ligature resistant opening?
Look at the Marks USA 5PDN, a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel that is described as ligature resistant and ADA compliant. It operates with a paddle rather than a lever. The TownSteel MSE-W uses forged brass or cast zinc levers in eight lever styles on a wide brass escutcheon, which is a different operating shape for that environment.
17) Where do I get the door prep template for a TownSteel MSE mortise lock?
TownSteel publishes the MSS template for the mortise pocket and trim prep, and it is the drawing to cut from. The pocket must suit a 2-3/4 inch backset body with a 1-1/4 by 8 inch faceplate, and the escutcheon centers must match the 10-9/16 inch plate.
18) Is a BEST 45H mortise lock body the same thing as the TownSteel MSE-W?
They are both heavy duty mortise locks but they are sold at different levels of completeness and function. The BEST 45HCAC is a heavy duty mortise lock body with a public entrance function and field reversible operation, and the 45HCAINL is a heavy duty lockbody with an intruder function - lock bodies you then trim. The TownSteel MSE-W comes as a Grade 1 heavy duty exit function lock with its wide escutcheon, lever, ANSI strike and 1-1/4 by 8 inch stainless faceplate, and handing is selected at order as LH, RH, LHR or RHR rather than reversed in the field.
19) Would an Emtek 3106 Manhattan mortise entrance lockset work where the TownSteel MSE-W is specified?
No. The Emtek 3106 Manhattan is a dummy function mortise entrance lockset, as are the Emtek 3104 Hamilton and 3102 Memphis - decorative trim with no latching action. The TownSteel MSE-W is a commercial Grade 1 heavy duty exit function lock with a working anti-friction latch bolt and ANSI strike, intended for commercial openings.
20) Do I need a full mortise lock like the TownSteel MSE-W or just a mortise deadbolt or thumbturn?
If the opening already has a latching device and you only need a secondary bolt, a standalone deadbolt is the smaller scope: the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, the same backset the TownSteel MSE-W uses, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. If you are only replacing a broken turn piece, the Sargent 130KB and 130W are standard duty mortise thumbturns. The MSE-W is the full assembly - lock body, wide escutcheon, lever, brass thumb turn and ANSI strike.
