TownSteel MSE-W Series Storeroom with Deadbolt Function - Heavy Duty Wide Escutcheon Mortise Lock, Double Cylinder

The MSE-W mortise lock is built on a 2-3/4 inch backset with a 1-1/4 x 8 inch stainless steel faceplate, which is the standard commercial mortise pocket and faceplate size. If the door is already prepped for a 2-3/4 inch backset mortise body with an 8 inch face, the lock body will drop in. The escutcheon trim measures 10-9/16 x 2-3/8 x 9/32 inches in brass, so check that your existing trim cutouts fall inside that footprint before you swap.

Storeroom function means the outside lever is always locked and a key retracts the latch; the inside lever always retracts the latch for free egress. The double cylinder part refers to the deadbolt: it is keyed on both sides, so it must be thrown and retracted by key from either face, not by a thumbturn. That suits stockrooms, mechanical rooms, and IT closets where you do not want anyone throwing the deadbolt by hand. Note that a key-both-sides deadbolt is restricted on egress doors in many jurisdictions, so it is worth confirming your local code before you specify it on a path of egress.

It should. The MSE-W ships with an ANSI strike in plated or stainless steel, and the latch bolt is a stainless steel split anti-friction bolt with 3/4 inch projection. Any frame already prepped for a standard ANSI 4-7/8 inch mortise strike will take it, and the 3/4 inch throw is the normal engagement for that prep. There is also a stainless guard bolt that deadlocks the latch when the door is closed.

Yes, handing is a required selection and there are four choices: LH (left hand), RH (right hand), LHR (left hand reverse), and RHR (right hand reverse). Reverse bevel applies when the door swings out toward you from the secure side, which is common on exterior and stair doors. Get this wrong and the lever and bevel will be backwards on the opening.

Keying is a required choice at order: KD keyed different (the standard), KA keyed alike for multiple locks on one key, or a specific key code for special keying into an existing system. If you are adding to a master keyed facility, choose the key code option and supply the code. There is also an SFIC prep, less core version if your locksmith is already running small format interchangeable cores and wants to pin and install their own.

The MSE-W is a keyed double cylinder storeroom mortise lock with lever trim and a thumb turn, so it does more than hold a door bolted. If the opening needs only a bolt, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset - the same backset the MSE-W uses - and the Kaba Ilco 185 Series is a deadbolt-function mortise lock supplied with no handing. Neither provides latching or lever operation, so they suit a secondary bolt or a door with separate push/pull hardware.

No. The MSE-W is a mechanical, non-electronic mortise lock, keyed with a double cylinder. If the opening is tied to access control, the Command Access ML190 is a heavy-duty motorized mortise lock with storeroom function and field selectable EL/EU operation on 24VDC, the BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, 12/24VDC, for 1-3/4 inch doors.

Two Grade 1 mortise locksets carry the same storeroom function as the TownSteel MSE-W: the Accentra 8805FL from the 8800 Series, and the Cal-Royal NM8080, which lists a 1-3/4 inch door thickness and an interchangeable core option. The MSE-W itself is a Grade 1 heavy duty mortise lock with a 2-3/4 inch backset, 3/4 inch stainless latch projection, and a 1-1/4 inch by 8 inch stainless faceplate, so confirm the existing door prep matches before swapping brands. The MSE-W differs from both in trim: it uses a 10-9/16 inch by 2-3/8 inch brass wide escutcheon rather than rose trim.

The MSE-W is a storeroom function lock, so the outside lever stays fixed and key access controls entry. For classroom control, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series, also listed for 1-3/4 inch doors. If the requirement is a dormitory or corridor exit function with a single cylinder deadbolt, the Sargent 7925 is a Grade 1 heavy duty option in the 7900 Series with rose trim.

Several mortise-family items share the look but provide no keyed security. The Schlage L0170 is a Grade 1 mortise non-keyed half dummy trim, and the Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan, and 3019 Brisbane are dummy-function mortise entrance locksets. The Schlage PM010 and Falcon MA101 are Grade 1 passage mortise locks, non-keyed, and the Sargent 130KB and 130W are mortise thumbturns only. The MSE-W, by contrast, is a keyed double cylinder storeroom lock with a 3/4 inch stainless latch bolt and stainless guard bolt.

The MSE-W uses lever trim in forged brass or cast zinc with a brass thumb turn, which is not suited to a ligature-resistant 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 a passage function, so it provides no keyed control where the MSE-W provides double cylinder storeroom keying.

The standard cylinder version arrives with TownSteel conventional cylinders in place, ready to use once keyed. The SFIC prep, less core version comes machined for a small format interchangeable core but ships without the core, so you supply and install your own to match an existing SFIC system. Both are offered across every lever style. Because this is a double cylinder storeroom lock, remember the deadbolt is keyed on both faces, so SFIC buyers need cores for both sides.

It is an ANSI Grade 1 heavy duty commercial mortise lock, which is the top durability classification for institutional openings and what most school, healthcare, and government specs call for. Grade 1 mortise is the usual standard for high traffic doors. The lock is mechanical, not electronic, so it has no power or battery requirement.

A wide escutcheon plate covers a larger area of the door face, which hides old prep holes and scarring from a previous lockset and gives a single plate for lever and cylinder. The MSE-W escutcheon is brass and measures 10-9/16 x 2-3/8 x 9/32 inches. Rose trim uses two small separate roses and shows more of the door, so it is the choice when the door face is clean or the spec calls for a minimal look. Hager's 3800 Series, for instance, is offered both ways, the 3810E with escutcheon and the 3810S with rose.

Two straightforward options. The Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option, listed for 1-3/4 inch doors. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. Both give you storeroom function without the key-both-sides deadbolt, which matters on egress doors where a double cylinder deadbolt is often not permitted.

Not directly - the MSE-W is a keyed mechanical lock with lever trim and a thumb turn, so credential management stays with the key system. Keypad mortise locks change how the door is operated: the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock listed for wide stile. Note the DL3500CR door thickness range and function differ from a 2-3/4 inch backset mechanical storeroom lock, so verify the door before treating it as a swap.

The MSE-W ships as a complete lockset with forged brass or cast zinc levers, a brass escutcheon, and a brass thumb turn. If existing trim is being reused, the BEST 45HCA heavy duty mortise lock body is offered in public entrance function with field reversible operation and in intruder function, and the Baldwin 6310 is a 2-1/2 inch backset entrance/storeroom mortise lock body for 1-3/8 inch and over doors, in knob by knob or as the 6310190RRLS right hand reverse lever by lever. Note that the Baldwin bodies use a 2-1/2 inch backset where the MSE-W uses 2-3/4 inch.

A storeroom function such as the MSE-W keys from outside and gives no inside privacy control beyond its thumb turn. For dedicated privacy openings, the Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset listed for 1-3/4 to 2 inch doors - the same backset dimension the MSE-W uses, which keeps the door prep consistent.

The MSE-W is fixed as a storeroom function with double cylinder keying. For office or entrance control, the Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, non-keyed, for 1-3/4 to 2-1/2 inch doors. The Baldwin 6301 entry/apartment mortise lock body is another route, offered knob by knob or as the 6301LS lever by lever on a 2-1/2 inch backset.

For openings where a published fire rating drives the submittal, the Falcon MA101 Grade 1 heavy duty mortise passage lock is listed as fire rated, the Schlage Electronics LEMD-GRW Grade 1 ENGAGE wireless mortise lock carries a 3 hour rating, and the LEBMB-ADD mobile-enabled mortise lock is also listed at 3 hours for 1-3/4 inch doors. These differ in function from the MSE-W, which is a keyed Grade 1 storeroom lock with double cylinder keying, so match function first and confirm the label requirement with the door manufacturer.

The MSE-W can be ordered with a standard cylinder or with SFIC prep, less core, so a facility keyway can be dropped in. Among comparable Grade 1 storeroom mortise locksets, the Cal-Royal NM8080 lists an interchangeable core option for 1-3/4 inch doors. The Accentra 8805FL is the other Grade 1 storeroom mortise lockset in the same function class if you are standardizing a keyway across a building.

Seven lever styles are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel, and Tango. All of them come in 626 satin chrome, which is the standard commercial finish for matching existing satin chrome exit devices, closers, and hinges. Levers are forged brass or cast zinc plated to match the finish.

A brass thumb turn in the Classic Visible style is standard on the MSE Series, and the stop works is stainless steel of the rocker type. Keep in mind that on the double cylinder configuration the deadbolt is key operated from both faces, so plan your hardware schedule around key control rather than a turn on the deadbolt.

The MSE-W is rated heavy duty and Grade 1. The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series rated medium duty in a brushed steel finish, and the Dormakaba Saffire LX-I-M002 electronic RFID mortise lockset is BHMA Grade 2. Both trade the Grade 1 heavy duty construction of the MSE-W, which includes a stainless steel split anti-friction latch bolt and stainless rocker-type stop works, for lighter-duty hardware.
