TownSteel MSE-R-T-32-626 – Frequently Asked Questions

1) What does the Intruder function on the TownSteel MSE mortise lock actually do?
Intruder function on the MSE Series means the lock is keyed on both sides (double cylinder), so it can be locked or unlocked with a key from either the corridor side or the room side. That is what classroom-security or lockdown openings use: a teacher or occupant can secure the door from inside without stepping into the hallway. It is a mechanical lock, not electronic.
2) Will a TownSteel MSE mortise lock latch into the ANSI strike already in my frame?
It should. The MSE ships with a plated/stainless steel ANSI strike and uses a 2-3/4 inch backset with a 3/4 inch projection stainless steel split anti-friction latch bolt. The faceplate is 1-1/4 x 8 inches, which is the standard ANSI mortise pocket prep, so an existing ANSI-prepped frame and door pocket will take it. TownSteel publishes the MSS template if you need to check the prep before cutting.
3) Do I have to specify handing when ordering a TownSteel MSE mortise lock?
Yes, handing is a required selection: LH, RH, LHR or RHR. Reverse bevel doors (doors that swing out toward you) take the LHR or RHR option. Get this wrong and the lever and latch orientation will be backwards on the opening.
4) Can I get a set of these TownSteel mortise locks all on the same key?
Keying is a required choice at order time. KD (key different) is standard, KA keys multiple locks alike so one key runs a group of doors, and a specific key code can be requested for special keying. Property managers standardizing a building usually want KA across the group, or a key code to match an existing system.
5) Is the TownSteel MSE the right lock for a classroom, or should I use a classroom function lock?
Intruder (double cylinder) locks key from both sides so the door can be secured from inside the room. A true classroom function keys only from the corridor. If your spec calls for classroom function instead, Grade 1 options include the Cal-Royal NM8070 classroom mortise lockset and the Corbin Russwin ML2003, both for 1-3/4 inch doors. For a keyed storeroom opening, the Cal-Royal NM8080 or Accentra 8805FL cover that function.
6) What is the closest equivalent to the TownSteel MSE intruder mortise lock from another manufacturer?
The BEST 45HCAINL is the nearest match on function: it is a heavy duty mortise lockbody with an intruder function, the same function the TownSteel MSE Series carries. The difference is scope - the TownSteel MSE is supplied as a complete heavy duty escutcheon lockset, keyed double cylinder, with lever style, finish and escutcheon height selected as part of the order, while the BEST 45HCAINL is the lock body. If you are specifying intruder function classroom-security openings and want the trim to arrive with the lock, the TownSteel MSE covers that in one part number.
7) We only need a keyed storeroom mortise lock, not intruder function. What is the alternative?
Two straightforward options. The Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series supplied with the Arcadia lever. The Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Both give you outside-always-locked, key-to-enter operation. The TownSteel MSE Series instead runs an intruder function with a double cylinder, which is what you want when the room must be locked and unlocked by key from inside as well.
8) What is the difference between the MSE Low and Regular escutcheon?
Both are escutcheon (plate) trim rather than round rose trim. The escutcheon measures 10-9/16 x 2-3/8 x 9/32 inches in brass, and the Low versus Regular choice changes the plate profile. Because the plate is 2-3/8 inches across its short dimension, check your stile has room before committing, especially on narrow frame doors.
9) Is the TownSteel MSE heavy duty enough for a school or hospital corridor?
It is an ANSI Grade 1 heavy duty commercial mortise lock, which is the top grade for commercial use and the level normally specified for high traffic institutional openings. Wear parts are stainless steel: the split anti-friction latch bolt, guard bolt, faceplate, and rocker type stop works. Levers are forged brass or cast zinc plated to the finish.
10) What lever styles and finishes can I get on the TownSteel MSE mortise lock?
Eight lever designs are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango. Finishes run 605 bright brass, 606 satin brass, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless and 630 satin stainless. For matching existing openings in a building, 626 satin chrome and 630 satin stainless are the common commercial standards.
11) I need an intruder function mortise lock but not with escutcheon trim. What else is there?
For a lock body only in the same intruder function, the BEST 45HCA heavy duty mortise lockbody with intruder function is the alternative. The TownSteel MSE is a complete double cylinder intruder lockset with brass escutcheon trim and lever, so pick it when you want trim and body together; pick the BEST lockbody when you are reusing or separately specifying trim.
12) Can the TownSteel MSE be tied into an access control system?
The MSE itself is a mechanical lock, built for single opening stand-alone use but prepared for integration into access control, with optional status sensors available: REX (request to exit), PRIV (privacy), DAJ (door ajar) and MKO (mechanical key override). If you need a credential reader or electric control at the lock instead, look at electrified mortise locks such as the BEST 45HW wired 12V/24V mortise lock or the Schlage L9092EU with RX.
13) Which mortise lock takes a small format interchangeable core besides the TownSteel MSE?
The TownSteel MSE Series can be ordered with SFIC prep less core or with a standard cylinder. Among comparable mechanical mortise locksets, the Cal-Royal NM8080 heavy duty Grade 1 storeroom lockset is offered with an interchangeable core option for 1-3/4 inch doors, and the BEST 45HCAINL heavy duty intruder lockbody is the body side of a BEST core system. Match the core format to the keyway your facility already standardizes on.
14) Is the Sargent 4874 double cylinder a substitute for the TownSteel MSE double cylinder mortise lock?
No. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset - bolt only, with no latch and no lever trim. The TownSteel MSE Series is a complete latch bolt lockset with a 3/4 inch projection stainless steel anti-friction latch, guard bolt, lever trim and escutcheon, also on a 2-3/4 inch backset. The 4874 would be an addition to an opening that already has a latchset, not a replacement for one.
15) What mortise lock should I use if the opening needs a keypad instead of keys?
If you want to drop keys entirely, the Alarm Lock DL3500CR is a Grade 1 electronic Trilogy mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors. The TownSteel MSE Series is a mechanical lock with no electronics, keyed double cylinder, so pick it when the site is managing brass keys rather than codes.
16) I need a non-keyed passage or privacy mortise lock on the same escutcheon look. What are my options?
For passage on an escutcheon, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors - the same backset the TownSteel MSE Series uses. For privacy with a deadbolt, the Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset for 1-3/4 inch doors. The TownSteel MSE is keyed on both sides, so use these where the door must never require a key.
17) Can I use the Sargent 7925 dormitory lock in place of the TownSteel MSE intruder lock?
They serve different openings. The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory exit function mortise lock from the 7900 Series with rose trim and a single cylinder deadbolt. The TownSteel MSE Series is intruder function, double cylinder, on an escutcheon rather than a rose, with the escutcheon offered in low and regular heights. If the existing door has an escutcheon cutout and pattern, the rose-trim 7925 will leave a different footprint.
18) What is the difference between the TownSteel MSE and the Corbin Russwin ML2003 for a classroom door?
The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, keyed outside to lock and unlock the outside lever. The TownSteel MSE Series is also Grade 1 but is an intruder function with a double cylinder, meaning the door can also be secured by key from the classroom side. Choose on whether your district's security plan requires locking from inside the room.
19) For a narrow ornamental iron door, can I use the TownSteel MSE double cylinder lock?
The Marks USA 21AC and 22AC are the ones built for that condition - both are entrance double cylinder ornamental iron mortise locks with round knobs, sized for 1 inch thick doors. The TownSteel MSE Series carries a 10-9/16 inch by 2-3/8 inch escutcheon and a 1-1/4 inch by 8 inch faceplate, which suits a standard commercial door rather than a narrow iron stile.
20) Does the TownSteel MSE include a thumbturn on the inside?
A brass thumb turn is part of the trim, Classic Visible style as standard. Stop works are stainless steel rocker type. Note this is the double cylinder intruder configuration, so the inside is keyed as well, which is the point of the function.
21) Is the BEST 45HCAC a drop-in for the same opening as the TownSteel MSE?
Not on function. The BEST 45HCAC is a heavy duty mortise lock body in public entrance function with field reversible operation. The TownSteel MSE Series is intruder function and is ordered to a specific hand - left hand, right hand, left hand reverse or right hand reverse. Public entrance leaves the outside lever unlocked or locked by key without the inside keying that intruder function provides, so confirm the function code on the door schedule before swapping.
22) Is an Emtek Brisbane or Manhattan mortise entrance set an alternative to the TownSteel MSE?
No. The Emtek 3019 Brisbane and 3106 Manhattan mortise entrance locksets are dummy function - trim only, with no working latch or keyed operation. The TownSteel MSE Series is a commercial Grade 1 heavy duty keyed lock with a double cylinder and a working latch bolt. Use the Emtek dummy sets only on an inactive leaf.
