TownSteel MSE-W-T-33-626 – Frequently Asked Questions

1) What does the intruder deadbolt function on the TownSteel MSE-W mortise lock actually do?
It is a lockdown function. The MSE-W is a keyed mortise lock with a double cylinder deadbolt, so the deadbolt can be thrown or retracted by key from either side of the door. In a classroom or office lockdown, staff secure the opening without stepping into the corridor. Because both sides are cylinder operated rather than thumbturn, egress requires a key on the inside as well, so confirm your local egress code allows double cylinder on that opening.
2) What backset and latch projection does the MSE-W mortise lock have, and will it hit my existing ANSI strike?
The MSE-W runs a 2-3/4 inch backset with a 3/4 inch projection stainless steel split anti-friction latchbolt, and it ships with an ANSI strike in plated or stainless steel. If the door already has a standard ANSI mortise prep with a 2-3/4 backset, the latch lines up. The faceplate is 1-1/4 by 8 inches stainless, which is the standard ANSI mortise faceplate footprint.
3) Do I have to specify handing when ordering the TownSteel MSE-W mortise lock?
Yes, handing is a required selection: LH, RH, LHR, or RHR. Determine it from the hinge side and whether the door swings toward you or away. Get it wrong and the lever and latch orientation will be backwards on the opening.
4) Can I get the TownSteel MSE-W keyed alike with the other locks in my building?
Keying is a required choice at order: keyed different as standard, keyed alike for multiple locks on one key, or a specific key code for an existing system. Property managers standardizing a floor or a building should pick keyed alike, or supply the key code if you are matching an existing master system.
5) Does the TownSteel MSE-W take small format interchangeable cores?
It can. Each lever style is offered either with a standard cylinder or with SFIC prep less core, so locksmiths running a house SFIC system order the SFIC prep version and drop in their own cores. Note the less-core option ships without cores, so you need to supply them.
6) If I only need a double cylinder deadbolt and not a full lockset, what should I use instead of the TownSteel MSE-W?
The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which matches the 2-3/4 inch backset the TownSteel MSE-W uses. The 4874 is deadbolt only, with no latch or lever trim, so it suits an opening where a separate handle or pull already carries the door. The MSE-W is a complete intruder function lockset that adds a 3/4 inch projection anti-friction stainless latch bolt, guard bolt and lever trim on both sides.
7) What is the closest equivalent to the TownSteel MSE-W intruder mortise lock from another manufacturer?
The closest match on function is the BEST 45HCAINL, a heavy duty mortise lock body with an intruder function. The TownSteel MSE-W is also a heavy duty mortise lock with an intruder function, so the two line up on what the lock does at the opening. The difference is scope: the BEST 45HCAINL is supplied as a lock body, while the MSE-W is a complete double cylinder assembly with wide brass escutcheon trim measuring 10-9/16 inch by 2-3/8 inch and a choice of Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel or Tango levers.
8) How big is the escutcheon plate on the TownSteel MSE-W, and will it cover the old trim holes?
The wide escutcheon measures 10-9/16 x 2-3/8 x 9/32 inches and is brass, plated to match the finish. That is a tall, narrow plate, so it covers a lot of vertical prep on the door face but only about 2-3/8 inches across. If you are replacing rose trim, measure the exposed holes against that width before assuming it hides them.
9) Is the TownSteel MSE-W heavy duty enough for a school or other high traffic commercial opening?
It is a Grade 1 heavy duty commercial mortise lock, the top ANSI/BHMA durability tier for door hardware. Internals back that up: stainless steel latchbolt, stainless guard bolt, stainless rocker type stop works, and forged brass or cast zinc levers plated to the finish.
10) Is the TownSteel MSE-W an electronic or access control lock?
No, it is a mechanical key operated mortise lock. If you need a standalone electronic mortise lock on the same kind of opening, ZenSupply carries the Schlage CO-100 standalone electronic mortise lock with keypad reader and the Alarm Lock DL3500CR Trilogy Grade 1 electronic mortise lock with 300 user codes.
11) What is an alternative to the TownSteel MSE-W if I need a different lock function on the same mortise prep?
Function drives the choice. For a classroom function instead of intruder, the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset. For storeroom, the Cal-Royal NM8080 offers an interchangeable core option like the SFIC prep version here. If you want another intruder function lock body, the BEST 45HCA heavy duty mortise lockbody carries the same intruder function.
12) Can I add request-to-exit or door ajar monitoring to the TownSteel MSE series?
The MSE series offers optional status sensors: REX (request-to-exit), PRIV (privacy), DAJ (door ajar), and MKO (mechanical key override). Those are what let the lock report into an access control system on a single opening. Specify them at order time, since they are not standard on the base mechanical lock.
13) Is there an electronic version if we want keypad access instead of the TownSteel MSE-W mechanical lock?
The TownSteel MSE-W is a non-electronic mechanical lock. For keyed-entry replaced by codes, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 to 1-7/8 inch thick, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. The Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card back-to-back mortise lock. None of these carry the MSE-W double cylinder intruder configuration.
14) What is a storeroom function mortise alternative to the TownSteel MSE-W for a back-of-house door?
For storeroom function, the Accentra 8805FL is a Grade 1 mortise lock in the 8800 Series with an Arcadia lever, 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. Storeroom keeps the outside lever always locked with key entry, whereas the TownSteel MSE-W is a double cylinder intruder function lock keyed on both sides.
15) We use small format interchangeable cores across the building - does the TownSteel MSE-W support that, or do we need a different brand?
No brand change is needed. The TownSteel MSE-W is offered with SFIC prep, less core, alongside the standard cylinder option, so it accepts your existing core program. The Cal-Royal NM8080 also offers an interchangeable core option but is a storeroom function lock rather than a double cylinder intruder lock.
16) What mortise locks look similar to the TownSteel MSE-W with escutcheon trim but are not keyed?
The Hager 3810E is a Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inch, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, also 2-3/4 inch backset. They share the escutcheon look and the 2-3/4 inch backset of the TownSteel MSE-W but provide no key control, while the MSE-W is keyed on both sides in a double cylinder intruder configuration.
17) Our doors are thinner than standard commercial - is the TownSteel MSE-W still the right lock?
The TownSteel MSE-W is a commercial heavy duty mortise lock built for standard commercial openings with a 2-3/4 inch backset and a 1-1/4 inch by 8 inch faceplate. For thin ornamental iron stiles, the Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with round knob for 1 inch doors. Both share the double cylinder keying approach but are sized to a very different stile.
18) What lever styles and finish does the TownSteel MSE-W wide escutcheon mortise lock come in?
Eight lever designs are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel, and Tango. All are supplied in 626 satin chrome, the standard commercial finish, so the whole set will match existing 626 hardware on adjacent openings. The thumb turn is brass in the Classic Visible style.
19) Can I use a Sargent 130KB thumbturn in place of the TownSteel MSE-W double cylinder trim?
No. The Sargent 130KB is a standard duty mortise thumbturn for the 8200 Series, and the Sargent 130W is a mortise thumbturn with a round backplate for the 7800 Series - both are trim pieces, not locks. The TownSteel MSE-W is a complete heavy duty Grade 1 mortise lock, and its double cylinder configuration is keyed on both sides rather than thumbturn operated, although a brass Classic Visible thumbturn is the standard part where one is used.
20) Is the Emtek 3106 Manhattan mortise entrance set a substitute for the TownSteel MSE-W?
No. The Emtek 3106 Manhattan is a dummy function mortise entrance lockset, as are the Emtek 3019 Brisbane and 3104 Hamilton - dummy trim has no latch or key operation and is used on inactive leaves. The TownSteel MSE-W is a commercial Grade 1 heavy duty keyed mortise lock with a double cylinder intruder function.
