TownSteel MRX-L-34 Intruder Function Mortise Lockset with Anti-Ligature Stainless Steel Lever and Double Cylinder Deadbolt

The TownSteel MRX-L-34 is an ANSI Grade 1 mortise lockset with a ligature-resistant stainless steel lever, built for behavioral, mental, and psychiatric healthcare facilities housing patients at risk. Its double cylinder Intruder function includes a cylinder and fits doors with a 1-3/4" thickness range, mounting on both wood and metal doors. The 1-1/4" x 8" stainless steel face plate and 1-1/4" x 4-7/8" ASA strike add commercial-grade durability, and tamper-resistant mounting screws provide extra security.

TownSteel MRX-S-L-34-630 – Frequently Asked Questions

1) Will the TownSteel MRX-L-34 mortise lock fit a 1-3/4 inch door?
Yes, and only 1-3/4 inches. The MRX-L-34 is specified for a 1-3/4 inch door thickness, which is the standard commercial door. If your openings are thicker (a lead-lined or double-layer door in a behavioral health unit, for example), this is not the lock body to spec.
2) Can I use my existing ASA strike prep for the MRX-L-34?
The MRX-L-34 ships with a 1-1/4 by 4-7/8 inch ASA strike, which is the standard commercial frame prep, so it drops into a frame already cut for an ASA lip strike. The lock face plate is 1-1/4 by 8 inch stainless steel, so the door edge mortise needs to match that same standard ANSI mortise pocket.
3) What does the intruder function on the MRX-L-34 actually do?
It is a double cylinder intruder lock: a keyed cylinder on each side operates the deadbolt, with an auxiliary dead latch behind the latchbolt. In practice staff can lock the door from either side with a key, which is how behavioral health units handle lockdown of patient rooms and treatment areas without a thumbturn a patient could manipulate.
4) Is this lock suitable for a psychiatric or behavioral health facility?
That is what the MRX-L series is built for. The lever trim is ligature resistant stainless steel, the mounting screws are tamper resistant, and TownSteel states the lock is suitable for behavioral, mental, and psychiatric healthcare facilities housing at-risk patients. The lock body is ANSI Grade 1 heavy duty for high-traffic institutional openings.
5) Does the MRX-L-34 come with a cylinder, or can I use my own SFIC core?
Two choices. The standard build includes the cylinder. The other build is SFIC prep, less core, which leaves the housing ready for your own small format interchangeable core so the lock falls into an existing facility key system. Keying must also be specified: key different, key alike across multiple locks, or to a supplied key code.
6) What is the closest equivalent to the TownSteel MRX-L-34 intruder mortise lock from another manufacturer?
The MRX-L-34 is a Grade 1 heavy duty mortise lockset with intruder function and ligature-resistant lever trim. The closest functional match by lock function is the BEST 45HCA series heavy duty mortise lockbody with intruder function. The difference is scope: the BEST 45HCAINL is a lockbody, while the MRX-L-34 is supplied as a complete lockset with ligature-resistant stainless steel lever trim, tamper-resistant mounting screws, and a cylinder included.
7) Is there another ligature-resistant mortise trim option for a behavioral health door if a lever is not wanted?
Yes. 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 device, so it provides no locking; the TownSteel MRX-L-34 is a double cylinder intruder function lockset with a deadbolt and auxiliary deadlatch. Use the paddleset where the opening must stay free-swinging and the MRX-L-34 where the room must be secured.
8) What mortise lock should be used instead if the door is thicker than 1-3/4 inches?
The TownSteel MRX-L-34 is built for a 1-3/4 inch door. For thicker openings, the Hager 3810E passage mortise lock with escutcheon and the Hager 3850E office mortise lock both cover a 1-3/4 to 2-1/2 inch door thickness range, and the Baldwin 6301LS entry/apartment mortise lock body is listed for 1-3/4 inch and over. Those are passage, office, and entrance functions rather than an intruder function with ligature-resistant trim.
9) Should I order the escutcheon or the sectional trim on the MRX-L-34?
Both are offered in 630 satin stainless. Escutcheon (E) trim is a single full plate that covers the lever and cylinder area, which hides more of the door face and gives fewer edges on an anti-ligature opening. Sectional (S) trim uses separate roses and is the lighter-looking option, often chosen where existing doors already have sectional trim and you want the openings to match.
10) Can the MRX-L-34 be installed on a wood door, or steel only?
Either. TownSteel states the MRX-L mounts on both wood and metal doors, so the same lock can be standardized across hollow metal corridor doors and wood patient room doors in one facility.
11) How do I key several MRX-L-34 locks alike for a unit?
Pick the KA (key alike) option when ordering so the group operates on one key, which is the usual approach for a nursing unit or a wing. KD (key different) is standard if each door needs its own key, and a specific key code can be entered as text if you are extending an existing system. Alternatively order the SFIC prep less core version and pin your own cores.
12) I need a classroom or storeroom function mortise lock, not intruder. What else is there?
The MRX-L-34 is a double cylinder intruder lock and will not give you classroom or storeroom operation. For classroom function on a 1-3/4 inch door, the Cal-Royal NM8070 and the Corbin Russwin ML2003 are both Grade 1 classroom mortise locksets. For storeroom, the Cal-Royal NM8080 (with interchangeable core option) or the Accentra 8805FL are Grade 1 options.
13) If the opening only needs a classroom or storeroom mortise lock and not a ligature-resistant one, what are the alternatives?
For standard commercial openings, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, the Cal-Royal NM8080 is the Grade 1 storeroom version with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock with Arcadia lever. All are Grade 1 like the TownSteel MRX-L-34, but none carry the ligature-resistant stainless lever and tamper-resistant mounting screws that suit behavioral and psychiatric patient rooms.
14) Can a Sargent 4874 mortise deadbolt be used in place of the TownSteel MRX-L-34?
Only if the opening needs no latching. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset and no lever or latch. The MRX-L-34 is a double cylinder intruder lockset that combines a deadbolt with an auxiliary deadlatch and ligature-resistant lever trim, so it both latches and deadbolts on one mortise prep.
15) Would an electronic mortise lock work for a patient room instead of the TownSteel MRX-L-34?
Electronic mortise locks such as the Alarm Lock DL3500CR Grade 1 classroom lock with 300 user codes, the Schlage CO-100 standalone Grade 1 electronic mortise lock with keypad reader, and the Dormakaba E-Plex E5086 Grade 1 pushbutton and card mortise lock add credential-based access, but all present keypads, readers, and standard trim. The TownSteel MRX-L-34 is a non-electronic lockset whose value on a behavioral health door is the ligature-resistant stainless lever and tamper-resistant mounting screws.
16) What mortise lock matches the TownSteel MRX-L-34 if the room needs privacy instead of intruder function?
The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for a 1-3/4 inch door, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset covering 1-3/4 to 2 inch doors. Both match the MRX-L-34 on Grade 1 mortise construction for a 1-3/4 inch door, but they operate as bed and bath privacy sets rather than a double cylinder intruder lock with ligature-resistant trim.
17) Is the MRX-L-34 an electronic or access control lock?
No, it is purely mechanical and key operated. If you need credential or keypad control on a mortise prep, look at electronic mortise locks such as the Schlage CO-100 standalone keypad mortise lock or the Alarm Lock DL3500CR Trilogy, though neither is a ligature resistant design.
18) What finish does the MRX-L-34 lever mortise lock come in?
630 satin stainless steel, on every build. That matches the stainless face plate and is the standard finish on healthcare and institutional openings, so it will sit alongside existing 630 levers, push plates and hinges without a finish mismatch.
19) Are the Emtek mortise entrance sets a substitute for the TownSteel MRX-L-34?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance sets are dummy function, meaning they are trim only with no operating latch or bolt. The TownSteel MRX-L-34 is a working Grade 1 heavy duty intruder lockset with deadbolt, auxiliary deadlatch, and cylinder.
