TownSteel MSS-R-T-41-626 – Frequently Asked Questions

1) What does the single dummy function on the TownSteel MSS mortise lock actually do?
Single dummy means one side only, and it does not latch. The MSS single dummy is a non-keyed pull trim: the lever is fixed, there is no latchbolt operation and no key cylinder. It is used on inactive leaves of a pair, on closet or communicating doors, or wherever you want the same lever look as the working openings without any locking. If you need a lever that retracts a latch but stays unlocked, that is a passage function, not a dummy.
2) Why do I have to pick a hand on a dummy lever if it does not latch?
Handing is a required selection on the MSS dummy trim, with LH, RH, LHR and RHR offered. Lever throw direction and the escutcheon orientation follow the hand, so the trim matches the swing of the door it goes on. Pick the hand of the leaf the dummy is mounting to, not the active leaf beside it.
3) Will the MSS dummy trim match the other TownSteel mortise locks already on my doors?
That is what it is for. The MSS dummy uses the same sectional escutcheon trim and the same lever families as the working MSS mortise locks, so a dummy leaf reads identically to the latching openings. Levers come in Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango, and the escutcheon is offered in Low or Regular. Match the lever style, escutcheon height and finish to what is already installed.
4) Do I need to cut a full mortise pocket in the door for a dummy lever?
No lock body ships with the single dummy, so there is no latch or deadbolt to house and no 2-3/4 inch backset to lay out the way you would on a latching MSS lock. Prep the escutcheon mounting only. TownSteel publishes an MSS template, and that is what you should work from for hole centers.
5) I need the door to actually latch, not just carry a lever. What should I order instead of the TownSteel MSS dummy?
The MSS single dummy is a dummy function with no latching mechanism, so it is only for inactive leaves and pull applications. For a latching non-keyed mortise opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating. Hager also lists the 3810E passage mortise lock with escutcheon on a 2-3/4 inch backset.
6) What is the closest Grade 1 dummy mortise trim to the TownSteel MSS single dummy lever?
The Schlage L0170 half dummy trim is the nearest equivalent: it is a Grade 1, heavy duty, non-keyed mortise dummy lever listed for 1-3/4 inch doors in the L Series. The TownSteel MSS single dummy is also a Grade 1 heavy duty non-keyed mortise dummy, built with sectional trim and offered with eight lever styles including Artistic, Imperial, Regal and Tango across seven finishes from 605 Bright Brass to 630 Satin Stainless Steel.
7) What finishes does the TownSteel MSS sectional mortise trim come in?
Seven: 605 Bright Brass, 606 Satin Brass, 622 Matte Black, 625 Bright Chrome, 626 Satin Chrome, 629 Bright Stainless Steel and 630 Satin Stainless Steel. For a commercial corridor standardized on satin chrome or satin stainless, 626 and 630 are the usual picks. Levers are forged brass or cast zinc plated to match the finish symbol, so the dummy plates to the same code as the keyed locks in the series.
8) How big is the MSS escutcheon plate, and will it cover my old trim?
The MSS escutcheon measures 10-9/16 x 2-3/8 x 9/32 inches and is brass. On a retrofit, lay those numbers over the existing prep: a narrow sectional rose it will more than cover, but a wider escutcheon from another brand may leave witness marks. As a comparison, the Marks USA LA318 escutcheon is listed at 8-1/2 inch H x 2-3/4 inch W x 7/16 inch, so it is shorter and wider than the TownSteel plate.
9) Is the MSS dummy a Grade 1 commercial lock or a residential trim?
Commercial, heavy duty, and part of TownSteel's ANSI Grade 1 MSS mortise family. That matters on a dummy because the lever still gets pulled all day on an inactive leaf in a school or multi-family corridor. If you want a decorative brass dummy for a residential entrance instead, the Emtek mortise dummy sets like the 3104 Hamilton or 3106 Manhattan are that kind of product.
10) Does the MSS single dummy come with a cylinder, thumbturn or strike?
None of those. It is non-keyed, so no cylinder and no key override, and with no latch there is no strike to install. The ANSI plated or stainless strike, the 3/4 inch projection anti-friction latchbolt, the guard bolt and the brass thumbturn belong to the keyed and privacy MSS lock bodies, not to the dummy trim.
11) Is the MSS dummy electrified or can it take access control sensors?
Not electrified. The MSS dummy is a mechanical, non-electronic trim with no REX, privacy, door ajar or key override sensor options. If you need a mortise lock that ties into access control on that opening, look at a motorized or electromechanical body such as the Command Access ML190 with field selectable EL/EU operation on 24VDC, or the BEST 45HW wired electromechanical mortise lock for 12V/24V.
12) Is there a decorative dummy mortise lockset alternative to the TownSteel MSS for a residential-style entrance?
Emtek lists several dummy mortise entrance locksets in ornamental styles: the 3019 Brisbane in brass, the 3102 Memphis, the 3104 Hamilton and the 3106 Manhattan, all dummy function. The TownSteel MSS single dummy is specified for commercial use at ANSI Grade 1 heavy duty with sectional trim, a brass escutcheon in Low or Regular height, and forged brass or cast zinc levers plated to the finish symbol.
13) Can the Falcon MESC600DT dummy trim be used in place of the TownSteel MSS dummy mortise lock?
No. The MESC600DT is a dummy escutcheon lever trim made for Falcon M9900 Series exit devices and is fire rated for that application, so it mounts to an exit device opening rather than a mortise lock pocket. The TownSteel MSS single dummy is a mortise dummy with sectional trim and a 10-9/16 inch by 2-3/8 inch brass escutcheon for a mortise-prepped door.
14) What keyed mortise locks pair with the TownSteel MSS dummy on the active leaf of a pair of doors?
The MSS single dummy is non-keyed and handles the inactive leaf. For the active leaf, keyed Grade 1 mortise options include the Accentra 8805FL storeroom mortise lock in the 8800 Series, the Cal-Royal NM8080 Grade 1 storeroom lockset with an interchangeable core option for 1-3/4 inch doors, and the Corbin Russwin ML2003 Grade 1 classroom lockset in the ML2000 Series.
15) If the opening needs credential access instead of a dummy lever, what mortise locks cover that?
The TownSteel MSS single dummy is non-electronic and non-keyed. For access control at the door, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125 kHz proximity reader and a 3 hour fire rating, the Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with cylinder override, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors.
16) For a bathroom or bedroom door, what replaces the TownSteel MSS dummy function?
A dummy does not lock, so it is not a privacy solution. Privacy mortise options include the Hager 3840S Grade 1 privacy mortise lock on a 2-3/4 inch backset for 1-3/4 to 2 inch doors and the Cal-Royal NM8440 Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. The TownSteel MSS single dummy remains a non-keyed Grade 1 heavy duty mortise dummy for inactive leaves.
17) Our doors are prepped for a cylindrical bore, not a mortise pocket. What is the alternative to the TownSteel MSS?
The TownSteel MSS single dummy is a mortise lock type and needs a mortise pocket with a 1-1/4 inch by 8 inch faceplate prep. For a bored door, the Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors.
18) What is the difference between the Low and Regular escutcheon on the MSS trim?
It is the escutcheon profile on the sectional trim, and it is a required choice, so order the one that matches the other MSS openings in the building. Mixing Low and Regular on adjacent doors is the most common way a dummy leaf ends up looking wrong next to the active leaf.
