TownSteel MRX-S-L-12-630 – Frequently Asked Questions

1) What does the -12 dormitory/exit with T-turn function actually do at the door?
It is a dormitory or exit function operated by a T-turn on the inside. The deadbolt is thrown or retracted by the inside T-turn, and the key in the single outside cylinder also operates it, so a resident or staff member can secure the room from inside without a key. Inside lever always allows free egress. It is a single cylinder lock, so there is one keyed side.
2) Is this mortise lock suitable for a behavioral health or psychiatric unit?
That is what the MRX-L is built for. The lever trim is ligature resistant stainless steel and the mounting screws are tamper resistant, which is why it is specified for behavioral, mental health, and psychiatric facilities housing patients at risk. The ligature-resistant lever geometry is what separates it from a standard Grade 1 mortise lever.
3) Will the MRX-L-12 drop into an existing ANSI mortise pocket and strike prep?
It uses a 1-1/4 x 4-7/8 inch ASA strike and a 1-1/4 x 8 inch stainless steel face plate, which is standard ANSI mortise prep. If the door and frame already carry an ASA strike cut and a standard mortise pocket, the body and strike line up without new frame work. Confirm the existing pocket depth against the MRX mortise template before you cut anything.
4) Does the MRX-L-12 come with a cylinder, or can I use my own small format interchangeable core?
Two ways to buy it. The Standard cylinder version ships with a cylinder included. The SFIC Prep, Less Core version is machined for a small format interchangeable core but ships without the core, so you supply your own to match the facility's existing SFIC keying. If you are standardizing a building on one core system, take the SFIC prep.
5) What is the closest equivalent to the TownSteel MRX-L-12 dormitory/exit mortise lock in a conventional lever trim?
The Sargent 7925 is a Grade 1 heavy duty mortise lock with a dormitory/corridor exit function and a single cylinder deadbolt, using rose trim. The MRX-L-12 covers the same dormitory or exit with T-turn function at Grade 1 heavy duty, but with a ligature-resistant stainless steel lever and escutcheon or sectional trim with tamper-resistant mounting screws. Choose the 7925 where standard rose trim is acceptable and the MRX-L-12 where the opening is in a behavioral or psychiatric area.
6) Is there another ligature-resistant option for a behavioral health door instead of the MRX-L-12?
The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant, and finished in satin stainless steel. It is a passage set, so it does not key or latch secure; the MRX-L-12 is a keyed dormitory or exit with T-turn function supplied with a cylinder. Use the 5PDN on a free-swinging patient door and the MRX-L-12 where the room must be secured with a key.
7) Should I order the escutcheon or the sectional trim version?
Both trims are offered on the MRX-L-12. Escutcheon (E) gives you a single full plate covering the lock area, which hides older prep and gives less exposed hardware edge, a common choice on patient room doors. Sectional (S) uses separate roses and a smaller footprint, which suits matching existing sectional trim elsewhere in the facility. Function and lock body are the same either way; both come in 630 satin stainless.
8) Can I get multiple MRX-L-12 locks keyed alike for a whole wing?
Yes. Keying is a required selection: KD key different (the standard), KA keyed alike for multiple locks, or a specific key code if you are matching an existing system. Non-keyed functions take N/A. Order all the locks for a wing on one KA line so they come keyed together rather than rekeying in the field.
9) Is this a Grade 1 lock, and is it heavy enough for high traffic institutional doors?
ANSI Grade 1, heavy duty, and rated commercial. Grade 1 is the highest ANSI/BHMA durability tier and the level normally specified for hospital, dormitory, and institutional corridor doors that see constant use.
10) Do I need to order the strike, trim, and cylinder separately?
No. The MRX-L-12 is a complete lockset: mortise body, ligature-resistant lever trim in your choice of escutcheon or sectional, ASA strike, stainless face plate, tamper-resistant mounting screws, and a cylinder if you select the Standard cylinder option. The only thing you supply is the core if you order SFIC prep less core, plus your keying instructions.
11) What Grade 1 mortise lock should I use if the opening is a classroom rather than a dorm room?
The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors. The MRX-L-12 is a dormitory or exit with T-turn function on the same 1-3/4 inch door thickness, so the substitution is a function change rather than a prep change.
12) Can I use the Cal-Royal NM8440 privacy mortise lockset in place of the TownSteel MRX-L-12?
Only if the opening needs privacy rather than dormitory function. The NM8440 is a Grade 1 privacy/bed/bath mortise lockset with deadbolt for 1-3/4 inch doors. The MRX-L-12 is a keyed dormitory or exit with T-turn function with a single cylinder, and it carries a ligature-resistant stainless steel lever, which the NM8440 is not described as having.
13) What is the difference between the TownSteel MRX-L-12 and the Accentra 8805FL?
The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, so the outside lever is always locked and entry is by key only. The MRX-L-12 is Grade 1 dormitory or exit with T-turn, with a ligature-resistant stainless steel lever and tamper-resistant mounting screws, and mounts on wood or metal doors.
14) I need keypad access on a dorm door - what takes the place of the MRX-L-12?
The Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes and 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 for 1-3/4 inch doors. The MRX-L-12 is a mechanical lockset with no electronic operation, so switching to either of these changes both the credential and the door prep.
15) What mortise lock should I order if the door is thicker than 1-3/4 inch?
The Hager 3810E passage mortise lock with escutcheon and 2-3/4 inch backset covers 1-3/4 to 2-1/2 inch doors, and the Baldwin 6301LS entry/apartment lever by lever mortise lock body is rated 1-3/4 inch and over. The MRX-L-12 is specified for a 1-3/4 inch door, so an oversized leaf calls for one of those instead.
16) Can I order just a mortise lock body instead of the full MRX-L-12 lockset?
Yes, if you already have trim. The BEST 45HCAC is a heavy duty mortise lock body with public entrance function and field reversible operation, and the 45HCAINL is a heavy duty mortise lockbody with intruder function. Neither comes with the lever trim. The MRX-L-12 ships as a complete set with a ligature-resistant stainless steel lever, escutcheon or sectional trim, and a cylinder.
17) For an office or entrance opening rather than a dorm room, what Grade 1 mortise lock fits the same 1-3/4 inch door?
The Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option at the same thickness. The MRX-L-12 also fits a 1-3/4 inch door and is offered with either a standard cylinder or SFIC prep less core.
18) What finish does the anti-ligature MRX-L lever come in?
630 satin stainless steel, across both trim styles and both cylinder options. That is the usual finish for behavioral health and institutional openings, and the lever itself is stainless, not plated, so scratches don't show a different base metal.
19) Is the MRX-L-12 electronic or does it need any wiring?
Purely mechanical. No power, no wiring, no card reader. If the project calls for access control on these openings you are looking at a different platform, such as the Schlage CO-100 standalone electronic mortise lock or the BEST 45HW wired electromechanical mortise lock, neither of which offers the ligature-resistant trim.
20) Would a Sargent 130KB thumbturn work as a substitute for the T-turn on the MRX-L-12?
No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, a trim piece only, and the 130W is a similar thumbturn with a round backplate in the 7800 Series. The MRX-L-12 is a complete Grade 1 heavy duty mortise lockset with lever handle, cylinder, an ASA strike of 1-1/4 by 4-7/8 inch, and a 1-1/4 by 8 inch stainless steel face plate.
