TownSteel MRX-S-L-20-630 – Frequently Asked Questions

1) Will the TownSteel MRX-L-20 mortise lock fit a 1-3/4 inch door?
Yes, 1-3/4 inches is the door thickness the MRX-L-20 is built for, which is the standard commercial door thickness. It mounts on wood or metal doors. If your leaf is thicker or thinner than 1-3/4, this is not the lock body to specify.
2) Will the MRX-L-20 drop into an existing ASA mortise prep and strike?
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, so it lands in a standard ASA mortise pocket and frame prep. If the frame already has an ASA lip strike cutout at that size, the existing prep works.
3) What makes the MRX-L-20 an anti-ligature lock, and where is it used?
The lever and trim are ligature resistant, formed so a cord or strap cannot be looped and held, and the mounting screws are tamper resistant. TownSteel sells it for behavioral, mental health, and psychiatric facilities housing patients at risk, including patient room and dormitory doors. The lever is stainless steel.
4) How does the -20 function work for an apartment or dorm room door?
It is an entrance/apartment/dormitory function with a single cylinder outside and a T-turn inside. The key retracts the latch from the outside; the inside T-turn locks and unlocks the outside lever, and the inside lever always retracts the latch for egress. That is the usual arrangement for resident room and apartment doors.
5) Does the MRX-L-20 come with a cylinder, or can I use my own small format interchangeable core?
Two cylinder choices. Standard ships with a TownSteel cylinder included. SFIC Prep, Less Core comes prepped for a small format interchangeable core that you supply, which is what you want if the building is already keyed on an SFIC system.
6) What is a comparable Grade 1 entrance/office mortise lock if ligature resistance is not required?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch, rated for 1-3/4 inch doors, matching the MRX-L-20's Grade 1 rating, heavy duty level and 1-3/4 inch door thickness. What it does not carry is the MRX-L-20's ligature-resistant stainless steel lever and tamper-resistant mounting screws, which are the reason the MRX-L-20 is specified in behavioral health settings.
7) What is the closest ligature-resistant alternative to the TownSteel MRX-L-20 mortise lockset?
The MRX-L-20 is a Grade 1 mortise lockset with a ligature-resistant stainless steel lever and tamper-resistant mounting screws, intended for behavioral and psychiatric healthcare openings. The closest ligature-resistant peer is the Marks USA 5PDN, a Grade 1 hospital passage mortise push/pull paddleset described as ligature resistant and ADA compliant in satin stainless steel. The difference is operation: the MRX-L-20 is a keyed single-cylinder entrance/apartment/dormitory lock with a lever, while the 5PDN is a passage paddleset with no keyed function, so it suits openings that do not need to be locked.
8) If the opening needs classroom function instead of entrance/apartment, what mortise lock should be used?
The MRX-L-20 is built for entrance/apartment/dormitory duty with a T-turn and single cylinder. For a classroom opening, the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset for 1-3/4 inch doors, the same door thickness the MRX-L-20 is built for, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset also listed at 1-3/4 inch. Neither carries the ligature-resistant lever trim of the MRX-L-20, so they suit standard institutional doors rather than at-risk patient areas.
9) Should I order the escutcheon or the sectional trim on the MRX-L-20?
Both are offered, in 630 satin stainless steel. The E escutcheon is one continuous plate covering lever and cylinder, which hides old prep marks and gives fewer edges and fasteners exposed on a patient-facing door. The S sectional uses separate roses for lever and cylinder, a lighter look and less material to mount. Ligature-resistant lever is the same either way.
10) Can I get several MRX-L-20 locks keyed alike for a wing of rooms?
Yes. Keying is a required selection: KD key different (standard), KA keyed alike for multiple locks on one key, or a specific key code for special keying on an existing system. Order KA when a whole wing or a staff-access group should run on one key.
11) Is this mortise lock rated Grade 1 for a high-traffic institutional door?
Grade 1, heavy duty, commercial rated. Grade 1 is the top ANSI/BHMA durability tier for mortise locks, which is what a hospital corridor, dorm, or apartment entry sees for traffic.
12) What other ligature-resistant options are there if a lever is not allowed on the opening?
Where a facility bans levers entirely, a push/pull paddle is the alternative: the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant, ADA compliant, in satin stainless. It is passage only though, no keyed control, so it will not replace the keyed entrance/apartment function the MRX-L-20 provides.
13) Does the MRX-L-20 substitute for a storeroom mortise lock?
No. The MRX-L-20 is an entrance/apartment/dormitory function with a T-turn, so the inside lever always retracts the latch and the turn controls outside locking. For storeroom function, where the outside lever is always locked and key retracts the latch, use the Accentra 8805FL Grade 1 storeroom mortise lock with Arcadia lever or the Cal-Royal NM8080 Grade 1 storeroom mortise lockset, which also offers an interchangeable core option.
14) Is the Baldwin 6301LS entry/apartment mortise lock an equivalent to the TownSteel MRX-L-20?
They share the entrance/apartment function and a lever-by-lever configuration, but they are built for different jobs. The Baldwin 6301LS is a 2-1/2 inch backset mortise lock body listed for doors 1-3/4 inch and over, with decorative lever trim. The MRX-L-20 is a Grade 1 heavy duty stainless steel assembly with a ligature-resistant lever and tamper-resistant mounting screws for 1-3/4 inch doors. For behavioral health or high-abuse openings the MRX-L-20 is the one specified; for residential and light commercial entry doors the Baldwin is the closer fit.
15) What should I use if the dormitory opening needs an exit function with a separate deadbolt instead of a T-turn entrance lock?
The MRX-L-20 is a single cylinder entrance/apartment/dormitory lock operated by a T-turn. If the specification calls for dormitory exit function with a deadbolt, the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. It uses conventional rose trim rather than the ligature-resistant escutcheon or sectional trim offered on the MRX-L-20.
16) Can an electronic mortise lock replace the MRX-L-20 on a patient room door?
Electronic mortise locks such as the Schlage CO-100 Grade 1 standalone keypad mortise lock for 1-3/4 inch doors or the Alarm Lock DL3500CR Grade 1 Trilogy classroom mortise lock are Grade 1 mortise bodies, but they carry keypads, batteries and projecting trim. The MRX-L-20 is a non-electronic mechanical lock with a ligature-resistant stainless steel lever and tamper-resistant mounting screws, which is what behavioral and psychiatric facilities specify for at-risk patient areas. Use the electronic options on staff, office or classroom doors where access control is the requirement.
17) What is the simpler non-keyed alternative to the MRX-L-20 for corridor or closet doors?
The MRX-L-20 is a keyed single cylinder lockset. Where no locking is needed, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Both keep the mortise pocket prep while removing the cylinder and turn.
18) Is the BEST 45H mortise lock body a drop-in substitute for the MRX-L-20?
Not as a complete assembly. The BEST 45H is a heavy duty mortise lock body with public entrance function and field reversible operation, sold as a lock body that needs trim specified separately. The MRX-L-20 ships as a complete Grade 1 lockset with the ligature-resistant lever trim, escutcheon or sectional, and a cylinder included. If you are only replacing a failed lock body behind existing trim, a body-only item is the right scope; if you need the ligature-resistant trim itself, it is not.
19) Is the MRX-L-20 an electronic or access-control lock?
No, it is fully mechanical, key and T-turn only. If the opening needs credential access or audit trail, a mortise electronic lock is the direction to go, for example the Schlage CO-100 standalone keypad mortise lock, Grade 1 heavy duty for 1-3/4 inch doors, though it does not carry ligature-resistant trim.
20) What finish does the MRX-L-20 come in, and will it match other stainless hardware in the building?
One finish: 630 satin stainless steel, across both escutcheon and sectional trim. 630 is the standard institutional satin stainless, so it lines up with the satin stainless hinges, push plates, and closers typically specified in healthcare corridors.
21) What mortise privacy lock pairs with the MRX-L-20 on bathroom doors in the same facility?
For bath and bedroom doors alongside MRX-L-20 entrance openings, 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. Both match the MRX-L-20's Grade 1 rating and 1-3/4 inch door thickness, though neither carries ligature-resistant lever trim.
22) Will a mortise thumbturn like the Sargent 130KB work in place of the MRX-L-20's T-turn?
No. The Sargent 130KB is a standard duty mortise thumbturn, a trim piece for an 8200 Series mortise lock, not a lockset. The MRX-L-20 is a complete Grade 1 heavy duty mortise lockset whose T-turn is part of the ligature-resistant trim and is not interchangeable with a conventional projecting thumbturn.
