TownSteel MSE-W-T-07-626 – Frequently Asked Questions

1) How does the storeroom function work on the TownSteel MSE-W mortise lock?
Storeroom function: the outside lever is always locked and the key retracts the latch to get in, while the inside lever always retracts the latch for free egress. It's the standard choice for janitor closets, storage rooms, IT and electrical rooms where the door must never be left unlocked. The MSE-W is a single cylinder lock, so there is one keyed cylinder on the outside only.
2) What backset and latch throw does this TownSteel mortise lock have, and will it hit my existing ANSI strike?
It's a 2-3/4 inch backset mortise lock with a 3/4 inch projection stainless steel split anti-friction latch bolt, plus a stainless guard bolt. The faceplate is 1-1/4 x 8 inches stainless, and an ANSI strike in plated/stainless steel is part of the package. If your frame already has a standard ANSI 4-7/8 inch strike prep and your door has a 2-3/4 backset mortise pocket, the lock lines up; reuse the frame prep and install the supplied strike.
3) Do I have to specify handing when ordering this TownSteel wide escutcheon mortise lock?
Handing is required. You choose LH (left hand), RH (right hand), LHR (left hand reverse) or RHR (right hand reverse). Stand outside the door: if the hinges are on your left it's left hand, and if the door swings toward you it's a reverse hand. Get this wrong on a lever mortise lock and the lever points the wrong way.
4) Can I get these TownSteel storeroom locks keyed alike across a building?
Yes. Keying is selected at order: KD (key different, the standard), KA (key alike) for multiple locks that should share one key, or a specific key code for special keying, entered in the key code field. Property managers standardizing a set of storage and mechanical rooms typically take KA so one key runs the whole group.
5) Should I order the standard cylinder or the SFIC prep less core version?
Two cylinder builds are offered. Standard comes with the cylinder and keys supplied. SFIC Prep, Less Core ships prepped for a small format interchangeable core with no core included, which is what a locksmith or institutional shop wants if the facility already runs its own SFIC keyway and stocks cores. If you have no existing core program, take the standard.
6) Will a TownSteel MSE-W drop into a cylindrical lock prep?
No. This is a mortise lock, so the door needs a machined mortise pocket in the edge plus through holes for the lever spindle and cylinder, not a 2-1/8 inch cross bore. If your doors are prepped cylindrical, either the door gets re-prepped or you go with a cylindrical lock such as the Schlage PC10 Grade 1 cylindrical.
7) What is a direct equivalent to the TownSteel MSE-W storeroom mortise lock from another manufacturer?
Two close equivalents are the Accentra 8805FL, a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080, a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option. Both match the MSE-W on the two things that decide a storeroom opening: Grade 1 and storeroom function. The MSE-W differs in trim style, using a wide brass escutcheon measuring 10-9/16 inches by 2-3/8 inches rather than rose trim, and it is ordered with either a standard cylinder or SFIC prep less core.
8) Can I get this storeroom opening on an access control system instead of a key?
The MSE-W is a mechanical lock, not electronic, though its housing is built for integration with access control and offers optional REX, privacy, door ajar and mechanical key override sensors. If you want the credential reader in the lock itself, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and Greenwich trim, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock. For a motorized mortise body that stays wired to a panel, the Command Access ML190 is a heavy-duty storeroom function motorized mortise lock with field selectable EL/EU operation on 24VDC.
9) Is this TownSteel mortise lock rated for high traffic commercial openings?
It's an ANSI Grade 1 heavy duty commercial mortise lock, the top grade in the standard, which is what you specify for schools, hospitals, dorms and other high cycle openings. Internals are stainless steel where it counts: split anti-friction latch bolt, guard bolt, faceplate and rocker type stop works.
10) Is this an electronic or access controlled lock?
No. The MSE-W is a mechanical, key operated mortise lock, not electrified. If you need a credential reader or standalone keypad on a Grade 1 mortise, look at the Schlage CO-100 standalone electronic mortise lock or the BEST 45HW wired electromechanical mortise lock instead.
11) The opening does not need to be keyed - is there a non-keyed mortise lock to use instead?
The MSE-W is a keyed single cylinder lock, so for a non-keyed opening look at a passage or privacy mortise instead. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and is fire rated. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset, matching the MSE-W backset, for doors 1-3/4 to 2-1/2 inches. For a bed or bath opening, the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset.
12) Is the Sargent 7925 a substitute for the TownSteel MSE-W?
No. The Sargent 7925 is a Grade 1 heavy duty mortise lock in the 7900 Series with corridor/dormitory exit function, rose trim and a single cylinder deadbolt. The MSE-W is a storeroom/closet function single cylinder lock with wide escutcheon trim and no deadbolt, using a 3/4 inch projection stainless steel latch bolt with a guard bolt. The functions behave differently at the door, so specify by function rather than by grade alone.
13) I only need to replace the mortise lock body, not the trim - what are my options?
The MSE-W ships as a complete storeroom lock with wide escutcheon trim and lever, so it is not a body-only order. If the existing trim is staying, the BEST 45H Series heavy duty mortise lock body is sold as a lock body with public entrance function and field reversible operation, and the BEST 45HCA heavy duty mortise lockbody covers intruder function. Baldwin 6310 is a mortise lock body for entrance/storeroom use, but note it is a 2-1/2 inch backset against the 2-3/4 inch backset of the MSE-W.
14) We standardize on small format interchangeable core keying across the building - which storeroom mortise locks support that?
The MSE-W can be ordered with SFIC prep less core, so your existing cores drop in, and keying is specified as keyed different, keyed alike, or to a key code. Among comparable Grade 1 storeroom mortise locksets, the Cal-Royal NM8080 heavy duty Grade 1 storeroom lockset also offers an interchangeable core option for 1-3/4 inch doors, which is useful if you are matching an existing facility standard on a second door type.
15) What lever designs and finish can I get on the TownSteel MSE-W?
Eight lever styles are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango, each in 626 satin chrome. Levers are forged brass or cast zinc, plated to match the finish symbol, so lever and escutcheon read the same across a floor. The thumb turn is brass, Classic Visible as standard.
16) Is there a template for prepping the door for this TownSteel mortise lock?
Yes, TownSteel publishes the MSS template for the mortise pocket and trim hole locations, linked from the product resources. Use it with the 2-3/4 inch backset and the 1-1/4 x 8 inch faceplate dimensions when laying out the door edge, and prep the frame for the supplied ANSI strike.
17) What is the difference between the TownSteel MSE-W and the Schlage L0170 for a storeroom door?
The Schlage L0170 is a Grade 1 heavy duty half dummy trim in the L Series, a non-keyed dummy lever for 1-3/4 inch doors, so it neither latches nor locks. The MSE-W is a keyed Grade 1 storeroom mortise lock with a latching bolt and single cylinder. Use a dummy like the L0170 only on an inactive leaf, and the MSE-W on the leaf that has to secure.
