TownSteel MRX-A-12-630-RHR – Frequently Asked Questions

1) Will the TownSteel MRX-A-12 mortise lock fit a 1-3/4 inch door?
Yes, and only that thickness. The MRX-A-12 is built for 1-3/4 inch doors, which is the standard commercial door thickness. It mounts on either wood or metal doors, so a hollow metal frame opening or a solid core wood door both work as long as the door is 1-3/4 inches and prepped for a mortise lock body.
2) What does the -12 dormitory/exit with T-turn function actually do on the door?
On the MRX-A-12, the outside is key operated and the inside always allows free egress. The T-turn on the secure side lets an occupant throw the lock without a key, so a resident can secure the room from inside while the key still gets staff in. It is a single cylinder function, keyed from one side only, and it is the typical dormitory or patient room arrangement rather than a classroom or storeroom function.
3) Is this TownSteel mortise lock suitable for a behavioral health or psychiatric patient room?
That is exactly what the MRX-A is built for. It uses a 5-point ligature-resistant stainless steel arch trim instead of a lever, so there is no protrusion to loop a cord over, and it ships with tamper-resistant mounting screws so the trim cannot be taken off the door with a common driver. TownSteel lists it for behavioral, mental, and psychiatric healthcare facilities housing patients at risk.
4) Which handing do I order for the MRX-A-12, and is it reversible?
Handing has to be specified at order. The MRX-A-12 is sold in four hands: LH, LHR, RH and RHR. Reverse hands (LHR, RHR) are the ones you need when the door swings out toward you, which covers most patient room and corridor openings where the door swings into the corridor. Stand outside the door, on the key side: if the hinges are on your left it is a left hand or left hand reverse.
5) Does the MRX-A-12 come with a cylinder, or do I need to supply my own?
Both routes are available. Ordered with the standard cylinder, the lock ships complete and keyed. Ordered as SFIC prep less core, you get the housing prepped for a small format interchangeable core but no core, which is what you want if the facility is already on an SFIC system and your locksmith pins and installs the cores in house.
6) What strike and faceplate prep does the MRX-A mortise lock need?
It uses a 1-1/4 by 4-7/8 inch ASA strike, which is the standard commercial mortise strike cutout, and the faceplate is 1-1/4 by 8 inch stainless steel. If your frame already carries an ASA mortise prep from a previous Grade 1 mortise lock, the strike pocket should line up without new frame work. New wood door installs need the mortise pocket cut to the MRX-A template.
7) Is there another ligature-resistant option if a mortise lockset is not needed on the opening?
Yes. 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 device, so it latches without keying. The TownSteel MRX-A-12 is a keyed single cylinder dormitory/exit lock with a ligature-resistant arch trim, so it is the choice where the room has to be locked and keyed; the 5PDN suits patient room or corridor doors that only need controlled latching.
8) What is the closest equivalent to the TownSteel MRX-A-12 dormitory/exit mortise lock from another brand?
The Sargent 7925 is the nearest functional match. It is a Grade 1 heavy duty mortise lock in the 7900 Series with a corridor/dormitory function, rose trim, and a single cylinder deadbolt. The TownSteel MRX-A-12 is also Grade 1 and heavy duty with a single cylinder keyed function, but it carries a 5-point ligature-resistant stainless steel arch trim and tamper-resistant mounting screws, which the Sargent rose trim version does not. If the opening is a behavioral health or psychiatric room where ligature resistance is required, the arch trim version is the one to specify; for a standard dormitory corridor, the 7925 covers the same lock function.
9) Can I get a run of these TownSteel ligature resistant locks keyed alike across a wing?
Yes. Keying is a required selection: keyed different (the default), keyed alike for a group of locks that should share one key, or a specific key code if the building is already on a master system and you need the new locks cut to it. For a facility standardizing a corridor or wing, keyed alike or key code is the way to keep one staff key working every door. If you order the SFIC prep less core version instead, keying is handled by whoever supplies the cores.
10) Is this lock heavy duty enough for a high traffic institutional corridor?
The MRX-A-12 is an ANSI Grade 1 mortise lock rated heavy duty, which is the top commercial grade and the level normally specified for healthcare, education and other institutional openings. Grade 1 mortise is a different class of product from a cylindrical lock; the lock body sits inside a pocket cut in the door edge rather than through a bored hole.
11) Is the TownSteel MRX-A-12 an electronic or access control lock?
No, it is purely mechanical, key and T-turn operated with no wiring, credential reader or battery. If the project calls for card or keypad access on a mortise prep, something like the Dormakaba E-Plex E5086 Grade 1 electronic pushbutton/card mortise lock or the BEST 45HW wired electromechanical mortise lock with 12V/24V operation covers that instead, though neither is a ligature resistant trim.
12) What should I use instead of the MRX-A-12 if the door is a classroom rather than a dorm room?
For a classroom function on a 1-3/4 inch door, the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset with an auxiliary deadlatch, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series, both listed for 1-3/4 inch doors. The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an ANSI strike and steel escutcheon for 1-3/4 inch doors if you need an occupancy indicator. The TownSteel MRX-A-12 is an apartment/dormitory function and also fits a 1-3/4 inch door, but its ligature-resistant arch trim is aimed at behavioral health rooms rather than classrooms.
13) Which mortise lock covers an apartment entry if I do not need the ligature-resistant trim?
The Baldwin 6301 is an entrance/apartment function mortise lock body for doors 1-3/4 inch and over, offered as knob by knob or, as the 6301LS, lever by lever. The Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. The TownSteel MRX-A-12 carries an apartment/dormitory function as well and is Grade 1 heavy duty, but it is built around a 5-point ligature-resistant stainless steel arch trim with tamper-resistant mounting screws for at-risk patient housing.
14) Can I use a Schlage or Alarm Lock electronic mortise lock in place of the TownSteel MRX-A-12?
They are not direct substitutes. The MRX-A-12 is a mechanical lockset with no electronics, keyed single cylinder, and a ligature-resistant arch trim. The Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes and a classroom function for doors 1-5/8 to 1-7/8 inch, and the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in a privacy function for 1-3/4 inch doors. Both add credential-based access but neither is described with ligature-resistant trim, so on a behavioral health opening they change the character of the hardware.
15) What looks like a substitute for the MRX-A-12 but is only a lock body or trim piece?
Several items in the mortise family are components rather than complete locksets. The BEST 45H is a heavy duty mortise lock body in a public entrance function and the 45HCA is a heavy duty lockbody with an intruder function, both bodies without trim. The Sargent 130KB and 130W are mortise thumbturns, not locks. The Schlage L0170 is a Grade 1 half dummy trim with no latching. The TownSteel MRX-A-12 ships as a complete lockset with its ligature-resistant arch trim and a cylinder included, so ordering a bare body or thumbturn against it will leave the opening short of parts.
16) If the spec calls for a privacy or bath function instead of dormitory/exit, what mortise lock fits?
The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with a 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 inch. The TownSteel MRX-A-12 is a keyed single cylinder dormitory/exit lock with a T-turn, so it holds the door secure from the corridor side while allowing free egress, which is a different behavior than a privacy set.
17) Which mortise lock should I order if I need SFIC compatibility across a facility?
The TownSteel MRX-A-12 is available with an SFIC prep, less core cylinder option alongside the standard cylinder, in all four handings. The Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors if a storeroom function is what the opening calls for. Standardizing on a single core system across both is a matter of specifying the SFIC prep at order time.
18) What is the difference between the TownSteel MRX-A-12 and the Accentra 8805FL mortise lock?
Both are Grade 1 mortise locks. The Accentra 8805FL is an 8800 Series storeroom function with an Arcadia lever, meaning the outside lever is always locked and requires a key. The TownSteel MRX-A-12 is an apartment/dormitory function with a T-turn and a 5-point ligature-resistant stainless steel arch trim rather than a lever, with tamper-resistant mounting screws, fitting a 1-3/4 inch door with a 1-1/4 by 4-7/8 inch ASA strike. Lever trim is a ligature point, which is why the arch trim version is specified on at-risk patient doors.
19) What finish does the TownSteel MRX-A-12 come in?
630 satin stainless steel is the finish across every configuration of the MRX-A-12, in all four hands and both cylinder options. 630 is the standard institutional finish, so it matches satin stainless hinges, push plates and closers already on most healthcare and dormitory openings.
20) Is a Falcon MA101 or Schlage PM010 a valid alternative to the MRX-A-12?
Only if the opening does not need to lock. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating, and the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors. Both are non-keyed passage devices. The TownSteel MRX-A-12 is a keyed single cylinder dormitory/exit lockset, so a passage latch will not provide the secured condition the dormitory function does.
