TownSteel MRX-L-29 Classroom Deadlock T-Turn Mortise Lockset with Anti-Ligature Stainless Steel Lever

The TownSteel MRX-L-29 is an ANSI Grade 1 heavy-duty mortise lockset engineered with a ligature-resistant stainless steel lever, purpose-built for behavioral, mental, and psychiatric healthcare facilities where patient safety is critical. Featuring classroom function with single cylinder keyed operation and a T-Turn deadlock design, this lockset includes a cylinder and tamper-resistant mounting screws for added security. Designed to accommodate doors with a 1-3/4" thickness range, the MRX-L-29 mounts onto both wood and metal doors for versatile commercial installation.

Key Features

  • ASA Strike Plate: 1-1/4" x 4-7/8" ASA strike ensures secure, reliable engagement with the door frame.
  • Ligature-Resistant Lever Design: Stainless steel lever construction minimizes ligature points, supporting patient safety protocols in behavioral and psychiatric healthcare settings.
  • Tamper-Resistant Mounting Screws: Specialized screws help prevent unauthorized disassembly or tampering in at-risk environments.

TownSteel MRX-S-L-29-630 – Frequently Asked Questions

1) Will the TownSteel MRX-L-29 mortise lock fit a 1-3/4 inch door?
Yes, and 1-3/4 inches is the only thickness the MRX-L-29 is built for. It mounts on wood or metal doors, so a hollow metal opening and a solid core wood opening both take the same lock. If your doors run thicker than 1-3/4, this is not the lock for that opening.
2) Is the TownSteel MRX-L-29 anti-ligature lock suitable for a behavioral health unit?
That is exactly what it is built for. The MRX-L lockset uses a ligature-resistant stainless steel lever and tamper-resistant mounting screws, and TownSteel positions it for behavioral, mental and psychiatric healthcare facilities housing patients at risk. It is a commercial, heavy duty, ANSI Grade 1 mortise lock, so it is also rated for the traffic those doors see.
3) What does the -29 classroom deadlock T-turn function actually do on a door?
The 29 function is a classroom deadlock with a T-turn: the deadbolt is thrown by key from the outside and by the turn piece on the inside, which is how a teacher or staff member locks the room down from inside without stepping into the corridor. It is a single cylinder keyed lock, so there is one cylinder, outside, and the T-turn replaces an inside cylinder.
4) Will the MRX-L-29 drop into an existing ANSI mortise 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 the standard ANSI mortise pocket and frame prep. If the door you are replacing already has a standard ANSI mortise pocket and ASA strike prep in the frame, the MRX-L-29 goes in without new frame work. Doors prepped for a non-ANSI or older T-strike will need the frame reworked.
5) Can I get the TownSteel MRX-L-29 prepped for small format interchangeable core?
Yes. Two cylinder choices are offered: Standard, which ships with a cylinder included, or SFIC Prep less core, for facilities keying into their own interchangeable core system. If you run a BEST-style SFIC masterkey system across the building, order the SFIC prep version and supply your own cores.
6) What is a comparable Grade 1 classroom mortise lockset if ligature resistance is not required?
The TownSteel MRX-L-29 is a Grade 1 mortise lockset with classroom function, built with a ligature-resistant stainless steel lever and tamper-resistant mounting screws for behavioral and psychiatric healthcare openings. Where that ligature resistance is not part of the spec, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series, also listed for 1-3/4 inch doors. Both carry conventional lever trim rather than a ligature-resistant lever.
7) Is there a ligature-resistant mortise option for an opening that needs push/pull rather than a keyed lever?
The TownSteel MRX-L-29 is a keyed classroom mortise lockset with a ligature-resistant lever and a single cylinder. For an opening that should not have a keyed lever at all, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset described as ligature resistant and ADA compliant in satin stainless steel. It operates as passage, so it gives no key control at the door, where the MRX-L-29 locks and unlocks by key.
8) Escutcheon or sectional trim on the MRX-L lock - which should I order?
Both are offered and both carry the ligature-resistant lever. The E escutcheon trim is a single full plate covering the lever and cylinder area, which gives a larger continuous surface and fewer edges on the door face. The S sectional trim uses separate rose and cylinder plates. Escutcheon is the usual choice on patient-room doors where you want minimal exposed hardware; sectional is the lighter-looking option. Both come in 630 satin stainless.
9) Can I order several of these locks keyed alike for a wing of patient rooms?
Yes. Keying is a required selection at order: KD key different (the standard), KA keyed alike when you want one key to run multiple locks, or a specific key code if you are matching an existing system. If you choose a key code, enter it in the key code field so the locks come cut to your system rather than needing a locksmith visit after delivery.
10) Is this an electronic lock, and is there an electronic classroom mortise alternative?
No, the MRX-L-29 is entirely mechanical, keyed with a cylinder and a T-turn, with no wiring or power required. If you want credential or code control on a classroom-function mortise door, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with classroom function and 300 user codes, and the DL2700CR is the weatherproof T2 version. Both list a 1-5/8 to 1-7/8 inch door thickness range rather than the single 1-3/4 the TownSteel is built to.
11) Can an electronic keypad mortise lock replace the MRX-L-29 on a classroom door?
The MRX-L-29 is a mechanical lockset with no electronic components. For keypad access control in classroom function, the Alarm Lock DL2700CR is a Grade 1 electronic mortise lock with classroom function and a weatherproof design, and the Alarm Lock DL3500CR is a Grade 1 electronic classroom mortise lock with 300 user codes. Both are listed for 1-5/8 to 1-7/8 inch doors, while the MRX-L-29 is listed for 1-3/4 inch doors, and neither carries the ligature-resistant lever trim.
12) If the opening needs storeroom rather than classroom function, what heavy duty mortise lock fits?
Classroom function on the MRX-L-29 lets a key lock and unlock the outside lever. Where the door must stay locked at all times with key entry only, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. Neither is built with the ligature-resistant lever the MRX-L-29 carries.
13) Does a Sargent 130KB thumbturn work as a substitute for the T-turn on the MRX-L-29?
No. The MRX-L-29 is a complete Grade 1 mortise lockset that includes the lock body, ligature-resistant lever trim, cylinder, a 1-1/4 inch by 8 inch stainless steel face plate and a 1-1/4 inch by 4-7/8 inch ASA strike. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, a trim piece only, as is the Sargent 130W thumbturn with round backplate for the 7800 Series. Those are ordered to add or replace a turn on a Sargent lock body, not to replace a full lockset.
14) What is the difference between the MRX-L-29 and a BEST 45H mortise lock body?
The MRX-L-29 ships as a complete classroom lockset with ligature-resistant stainless steel lever trim, cylinder and tamper-resistant mounting screws. The BEST 45HCAC is a heavy duty mortise lock body in the 45H series with public entrance function and field reversible operation, and the BEST 45HCAINL is a heavy duty 45HCA lock body with intruder function. Those are lock bodies, so trim and cylinder are specified separately.
15) Do I need to specify handing for the MRX-L-29?
Handing is not an option axis on the MRX-L-29; the ordering choices are trim (escutcheon or sectional), cylinder (standard or SFIC prep), finish, and keying. Confirm your door swing against the TownSteel MRX-L installation guide and MRX mortise template before cutting the pocket.
16) What finish does the MRX-L anti-ligature mortise lockset come in?
630 satin stainless steel, across every trim and cylinder combination. That matches the stainless lever and stainless face plate, so a wing outfitted with these locks stays consistent and there is no plated finish to wear through in a high-contact environment.
17) For a dormitory or corridor door instead of a classroom, what Grade 1 mortise lock applies?
The MRX-L-29 covers classroom function. For a corridor or dormitory opening, the Sargent 7925 is a Grade 1 heavy duty mortise lock in the 7900 Series with dormitory exit function, rose trim and a single cylinder deadbolt. It uses rose trim rather than the escutcheon or sectional ligature-resistant trim of the MRX-L-29.
18) If the room only needs privacy with a deadbolt rather than keyed classroom control, what else fits a 1-3/4 inch door?
The MRX-L-29 is a keyed single cylinder classroom lockset for 1-3/4 inch doors. If the opening only needs occupant privacy, the Cal-Royal NM8440 is a 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. Neither carries the ligature-resistant lever construction of the MRX-L-29.
