TownSteel MSE-R-T-14-626 – Frequently Asked Questions

1) What does storeroom function mean on this TownSteel mortise lock, and is it right for a stock room or mechanical room?
Storeroom function is the standard choice for stock rooms, mechanical rooms and utility closets: the outside lever stays locked at all times and is retracted only by the key, while the inside lever always retracts the latch for free egress. There is no way to leave the outside lever unlocked, so the door cannot be accidentally left open. The MSE is keyed and set up as a double cylinder configuration.
2) Do I have to specify handing when ordering the TownSteel MSE mortise lock?
Yes, handing is a required selection: LH, RH, LHR or RHR. Determine it from outside the door, standing on the side the key goes in. If the hinges are on your left it is left hand, and if that door swings away from you it is LH, toward you LHR. Getting it wrong means the latch bevel faces the wrong way on a keyed storeroom opening, so confirm the swing before you order.
3) Can I get these TownSteel mortise locks keyed alike across a building?
Keying is a required choice at order: keyed different (the standard), keyed alike for running multiple locks on one key, or a specific key code for special keying where you supply the code. Property managers standardizing a floor or a set of storage rooms usually take keyed alike; a key code order lets you add to an existing system rather than start a new one.
4) Does the TownSteel MSE mortise lock accept a small format interchangeable core?
Two cylinder builds are offered: standard cylinder, or SFIC prep supplied less core. The SFIC version comes without the core so you can drop in your own 6 or 7 pin small format core and keep the lock on the same system as the rest of the facility. If you are not running an IC system, order the standard cylinder version.
5) What is a direct equivalent to the TownSteel MSE storeroom mortise lock from another manufacturer?
The closest straight 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 for doors 1-3/4 inches thick. The TownSteel MSE Series is also Grade 1 heavy duty with a storeroom function, so all three cover the same opening; the difference is trim, since the MSE uses an escutcheon plate (offered in low and regular heights) rather than rose trim.
6) What should I use instead if the opening needs credential or keypad access rather than a mechanical key?
The MSE Series storeroom lock is a mechanical, non-electronic lock. For access control at the door itself, the Command Access ML190 is a heavy duty storeroom function motorized mortise lock with field selectable EL/EU operation on 24VDC, keeping the same storeroom function. Keypad options include the Alarm Lock DL3500CR Grade 1 electronic mortise lock with 300 user codes and the BEST 45HZ EZ Series electronic keypad mortise lock with key override. For credential reading, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating.
7) What is a non-keyed mortise lock alternative if I do not need a cylinder on the door?
The MSE Series lock here is keyed with a double cylinder function, so for an opening that needs no key control consider the Falcon MA101, a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Schlage PM010 Grade 1 passage latch mortise lock for 1-3/4 inch doors, or the Hager 3810E, a Grade 1 passage mortise lock with escutcheon trim and a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. The Hager 3810E is the nearest in appearance since it also uses escutcheon trim, matching the MSE's 2-3/4 inch backset.
8) Which mortise products look like a substitute for the MSE storeroom lock but will not actually latch a door?
Several mortise-family items carry similar names but do not operate a latch. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are dummy function mortise entrance locksets, and the Schlage L0170 is a Grade 1 heavy duty half dummy trim for 1-3/4 inch doors. The Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices, so despite having an escutcheon like the MSE it carries no lock body. The Sargent 130KB and 130W are mortise thumbturns only. The MSE Series is a complete Grade 1 keyed storeroom mortise lock with a 3/4 inch stainless steel anti-friction latch bolt and guard bolt.
9) My door is a narrow stile aluminum storefront - will the MSE mortise lock fit, or do I need something else?
The TownSteel MSE Series uses a 10-9/16 by 2-3/8 inch escutcheon and a 1-1/4 by 8 inch faceplate on a 2-3/4 inch backset, which suits a standard commercial door leaf rather than a narrow aluminum stile. For storefront and glass door work, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is listed for wide stile, and the Kaba Ilco BR Series is a glass door bottom rail lock.
10) Is this TownSteel mortise lock Grade 1, and is it heavy enough for a school or hospital corridor?
The MSE Series is an ANSI Grade 1 heavy duty mortise lock built for commercial use, which is the top ANSI/BHMA performance tier and the level normally specified for institutional and high traffic openings. It is a mechanical lock, not electronic, though the MS platform is built to be integrated into access control systems and offers status sensor options including REX, privacy, door ajar and mechanical key override.
11) What is the difference between the MSE low and regular escutcheon, and how much door face does the plate cover?
The escutcheon is brass and measures 10-9/16 x 2-3/8 x 9/32 inches, and it comes in two heights, MSE Low and MSE Regular. Escutcheon trim like this covers more of the door face than a rose, which is useful when you are replacing an older mortise lock and want to hide previous prep or wear marks. A plate this tall needs a door stile wide enough to take the 2-3/8 inch width clear of the glass stop.
12) Is the TownSteel MSE the right function for a classroom or an office door?
No. Storeroom means the outside lever is permanently locked and can never be left unlocked, which is wrong for a room people come and go from. For a classroom opening, look at the Cal-Royal NM8070 or the Corbin Russwin ML2003, both Grade 1 classroom mortise locksets for 1-3/4 inch doors. For an office or entrance door where the lever can be left free during the day, the Cal-Royal NM8050 office/entrance mortise lock with auxiliary deadlatch is the match.
13) If I only need a keyed deadbolt rather than a lever lockset, what mortise option covers that?
The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, the same backset the TownSteel MSE Series uses, and the Kaba Ilco 185 Series is a deadbolt function mortise lock with no handing required. The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for doors 1-5/8 to 1-7/8 inches. Unlike those, the MSE is a lever-operated storeroom lockset with escutcheon trim, so handing must be specified as LH, RH, LHR or RHR.
14) Can I use a mortise lock body alone if the door already has trim I want to keep?
Yes - the BEST 45H Series is a heavy duty mortise lock body with public entrance function and field reversible operation, and the BEST 45HCA Series is a heavy duty mortise lockbody with intruder function, both sold as bodies. The Baldwin 6310 is an entry/storeroom mortise lock body on a 2-1/2 inch backset for doors 1-3/8 inches and over, in knob by knob, with the 6310190RRLS as the right hand reverse lever by lever version. The TownSteel MSE Series ships as a complete lockset with brass escutcheon trim measuring 10-9/16 by 2-3/8 by 9/32 inches and a choice of eight lever styles.
15) For an office or entrance opening where staff need to lock and unlock the lever, what is the alternative to a storeroom lock?
A storeroom function like the TownSteel MSE keeps the outside lever locked at all times. Where the outside lever should be lockable and unlockable, the Cal-Royal NM8050 is a heavy duty Grade 1 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, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. The Baldwin 6301 covers entry/apartment function on a 2-1/2 inch backset for doors 1-3/4 inches and over, in knob by knob or, as the 6301LS, lever by lever.
16) What mortise option should I use for a restroom or patient room that needs privacy instead of key control?
The MSE Series lock is keyed on both sides as a double cylinder storeroom function, which is not a privacy arrangement. For privacy, the Cal-Royal NM8440 is a heavy duty Grade 1 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 for doors 1-3/4 to 2 inches. For a healthcare corridor needing hands-free operation, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
17) Is there a heavy duty mortise lock with a built-in deadbolt for a dormitory corridor?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. The TownSteel MSE Series differs in two ways that matter on a dorm door: it is a storeroom function with no deadbolt, and it uses escutcheon trim rather than rose, in low or regular height with a brass thumb turn as standard.
18) We are standardizing a building on SFIC cores - which mortise locks accept that?
The TownSteel MSE Series can be ordered with SFIC prep less core, so your own small format interchangeable cores drop in, or with a standard cylinder. Among comparable Grade 1 storeroom mortise locksets, the Cal-Royal NM8080 is offered with an interchangeable core option. Keying on the MSE side is specified at order as keyed different, keyed alike across multiple locks, or to a supplied key code.
19) What is the difference between the TownSteel MSE storeroom lock and an ornamental iron mortise lock like the Marks 21AC?
They suit different doors. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, listed for 1 inch door thickness - narrow gate and ornamental iron stiles. The TownSteel MSE Series is a Grade 1 heavy duty commercial mortise lockset with a 1-1/4 by 8 inch stainless faceplate and a 10-9/16 inch brass escutcheon, sized for a standard commercial door leaf. Both are double cylinder, so the distinction is door construction, not key function.
20) Is a Codelocks CL2255 a workable substitute for a Grade 1 mortise storeroom lock?
Not for the same duty level. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series, finished in brushed steel. The TownSteel MSE Series is a Grade 1 heavy duty mechanical mortise lockset for commercial use, with a stainless steel ANSI strike and rocker type stop works. For a high-traffic storeroom door the Grade 1 heavy duty bodies - the MSE, the Accentra 8805FL or the Cal-Royal NM8080 - are the like-for-like comparison.
21) What lever styles and finishes does the TownSteel MSE storeroom lock come in?
Eight lever designs are offered: Artistic, Congr, Gala, Imperial, Quest, Regal, Sentinel and Tango. Levers are forged brass or cast zinc, plated to match the finish. Seven finishes are available: 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 usual commercial standards.
22) What is the guard bolt on the TownSteel MSE for, and does it stop the latch being carded?
The guard bolt is a stainless steel auxiliary bolt that sits beside the main latch. When the door is closed it is depressed by the strike and deadlocks the latch bolt, so the latch cannot be shimmed or slipped with a card. The main latch itself is stainless, split and anti-friction, which lowers the drag on closers and gaskets at the strike.
