TownSteel MSE-R-T-08-626 – Frequently Asked Questions

1) What does the corridor function on the TownSteel MSE mortise lock actually do at the door?
Corridor (front door) function on the MSE Series is the single cylinder arrangement used on apartment entry and corridor openings: the key works the outside, and the inside thumb turn controls the outside lever. The thumb turn is brass, Classic Visible style as standard. Inside lever always retracts the latch for free egress. It is a mechanical lock, not electronic.
2) Will the MSE mortise lock latch into my existing ANSI strike and standard mortise pocket?
It is built to the standard commercial mortise prep: 2-3/4 inch backset, 1-1/4 x 8 inch stainless faceplate, and a 3/4 inch projection stainless latch bolt (split, anti-friction) with a stainless guard bolt. An ANSI strike in plated or stainless steel is part of the lock. If your door is already prepped for an ANSI A115.1 mortise pocket with a 2-3/4 inch backset and an ANSI strike in the frame, the lock body drops into that prep; the escutcheon holes are what you would need to verify, since the trim measures 10-9/16 x 2-3/8 x 9/32 inches in brass.
3) Do I have to specify handing when ordering a TownSteel MSE mortise lock?
Yes, handing is a required selection. Four choices: LH, RH, LHR, and RHR. Reverse handing refers to doors that swing out of the room, so an out-swinging apartment or corridor door takes LHR or RHR. Get it wrong and the lever and latch face the wrong way.
4) Can I key a run of MSE mortise locks alike for one building?
Keying is a required choice on the order: KD keyed different is standard, KA keys multiple locks alike, or you can supply a specific key code for special keying. For a property manager standardizing an apartment or corridor floor, KA across the group is the option to pick, with the key code field used when it has to match an existing system.
5) Does the MSE mortise lock take a small format interchangeable core?
You choose the cylinder at order time: SFIC prep less core, or a standard cylinder. SFIC prep ships without the core, so a locksmith or facility running its own SFIC system supplies and pins the core to match. If you are not running interchangeable cores, take the standard option.
6) If the door needs classroom function instead of corridor, what mortise lock should I use?
The TownSteel MSE is a corridor function lock with a single cylinder, so it will not give you classroom operation. For classroom function in a Grade 1 mortise, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors.
7) I need a storeroom function mortise lock, not corridor. What are the options?
The TownSteel MSE is built for corridor function. For storeroom, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The MSE also offers an SFIC prep less core cylinder option if interchangeable cores are what you are standardizing on.
8) What is the difference between the TownSteel MSE and the Schlage L9092EU corridor mortise lock?
Both are corridor function heavy duty mortise locks. The difference is electrification: the Schlage 03A L9092EU is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors. The TownSteel MSE is a mechanical, non-electronic lock with a single cylinder, though it can be integrated into access control systems and offers optional REX, PRIV, DAJ and MKO status sensors.
9) Can I use a Baldwin 6301 or 6310 mortise lock body in place of the TownSteel MSE?
Not as a direct drop-in. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, while the TownSteel MSE is built for a 2-3/4 inch backset, so the mortise pocket and cylinder hole locations differ. The Baldwin bodies are also entrance/apartment and entrance/storeroom functions rather than corridor.
10) What is the difference between the MSE low and regular escutcheon?
Two escutcheon heights are offered, MSE Low and MSE Regular. The regular plate is the full size listed at 10-9/16 x 2-3/8 x 9/32 inches in brass; the low version is the shorter plate for openings where the full-height trim does not suit the stile or where existing trim holes sit closer together. Either way it is escutcheon trim, not a rose.
11) Is this mortise lock heavy duty enough for a high traffic apartment building entrance?
The MSE Series is an ANSI Grade 1 heavy duty mortise lock built for commercial use, with stainless steel latch bolt, guard bolt, faceplate and rocker type stop works, and forged brass or cast zinc levers plated to the finish. Grade 1 is the top ANSI/BHMA durability tier, which is what you want on a building front door or corridor opening.
12) I need a corridor or dormitory function mortise lock but not TownSteel. What else is there?
Sargent's 7925 from the 7900 Series is a Grade 1 heavy duty corridor/dormitory exit function mortise lock, though it comes with rose trim and a single cylinder deadbolt rather than escutcheon trim. On the electrified side, Schlage's L9092EU with 03A lever is a heavy duty corridor function mortise lock with request to exit and 12/24VDC operation for 1-3/4 inch doors. The TownSteel MSE is the mechanical escutcheon-trim option of the three.
13) Should I use a mortise lock like the MSE or a cylindrical lockset on this opening?
A mortise lock needs a machined pocket in the door edge and gives you a heavier lock case, a 3/4 inch anti-friction latch with a separate guard bolt, and a 2-3/4 inch backset. A cylindrical lock, like the Schlage PC10 Grade 1 passage, only needs a bored hole and is faster to install but does not carry a separate deadlocking guard bolt in the same case. If the door is already mortise prepped, stay with mortise; converting a bored door to mortise means replacing the door or using a conversion kit.
14) Is the TownSteel MSE lock an electronic or access control lock?
No. The MSE Series here is a mechanical, keyed single cylinder mortise lock. If you need standalone or networked credential access on a mortise prep, look at an electronic mortise lock instead, such as the Alarm Lock DL3500CR Trilogy Grade 1 keypad lock with classroom function for 1-5/8 to 1-7/8 inch doors, or the Dormakaba E-Plex 2066 pushbutton keyless mortise lock.
15) Is there a simpler non-keyed mortise lock if the opening does not need a cylinder?
Yes. The TownSteel MSE is keyed with a single cylinder. If the opening needs no key, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, which keeps the escutcheon look. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors.
16) I need keypad or credential access on a corridor door. What should I look at instead of the TownSteel MSE?
The TownSteel MSE is a mechanical mortise lock, not electronic. For electronic access on a mortise prep, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 inch to 1-7/8 inch, the Schlage CO-100-MS is a Grade 1 heavy duty standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating.
17) Does a Sargent 4874 mortise deadbolt do the same job as the TownSteel MSE?
No. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset in the 4870 Series, so it provides deadbolt-only locking with no latch or lever operation. The TownSteel MSE is a complete corridor function mortise lockset with a single cylinder, escutcheon lever trim, a 3/4 inch projection anti-friction split latch bolt, and a stainless steel guard bolt. The two share the 2-3/4 inch backset but serve different purposes.
18) Is the BEST 45H mortise lock body an alternative to the TownSteel MSE?
The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA lockbody is offered in intruder function. Both are lock bodies rather than complete escutcheon locksets. The TownSteel MSE is a heavy duty Grade 1 corridor function lockset supplied with escutcheon trim, levers in eight styles, and handing specified as LH, RH, LHR or RHR at order.
19) Will an Emtek Brisbane or Manhattan mortise entrance set work as a substitute?
No. The Emtek 3019 Brisbane and 3106 Manhattan mortise entrance locksets are dummy function, meaning they are non-operating trim with no latch or locking action. The TownSteel MSE is a working corridor function mortise lock, keyed with a single cylinder, and is a commercial Grade 1 heavy duty product.
20) What lever styles and finishes can I get on the TownSteel MSE mortise lock?
Eight lever designs: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango. Seven finishes: 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 on adjacent openings in the same BHMA number will match.
21) Is there an installation template for prepping the door for this TownSteel mortise lock?
Yes. TownSteel publishes the MSS template PDF for this mortise prep, linked from the product information, and it gives the pocket, faceplate and trim hole layout. Prep to 2-3/4 inch backset with a 1-1/4 x 8 inch faceplate cutout.
22) Is there a push/pull paddle mortise option instead of a lever for an accessible or behavioral health opening?
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 passage function with no cylinder. The TownSteel MSE is a corridor function keyed lockset and is supplied with lever trim in styles including Artistic, Gala, Imperial and Sentinel.
