TownSteel MRX-A-05-630-RH – Frequently Asked Questions

1) What does classroom function mean on the MRX-A-05, and is it the right lock for a patient room?
Classroom function means the outside trim is locked and unlocked by key from the outside only; there is no inside locking control, so a patient or occupant can't lock themselves in, and the inside always releases for egress. That's why it's the common choice for behavioral health corridors and patient rooms where staff control access. The MRX-A is intended for behavioral, mental, and psychiatric facilities housing at-risk patients.
2) What makes the TownSteel MRX-A ligature resistant compared to a standard lever mortise lock?
Instead of a lever or knob that a cord can be looped over, the MRX-A uses a 5-point ligature-resistant stainless steel arch trim, so there is no protruding graspable handle. It also ships with tamper-resistant mounting screws so the trim can't be pulled off with common tools. A standard lever mortise lock offers neither.
3) Do I need to order a cylinder separately for the MRX-A-05?
Not with the standard cylinder option, the MRX-A ships with a cylinder included. If your facility keys to a small format interchangeable core system, order the SFIC Prep, Less Core version instead and supply your own core. Both cylinder choices are offered in all four handings.
4) How do I determine the handing I need for the MRX-A-05 mortise lock?
Four handings are offered: LH, LHR, RH, and RHR. Stand outside the door (the keyed side). If the hinges are on your left it's left hand; on your right, right hand. If the door swings toward you rather than away, it's the reverse version, LHR or RHR. Getting this wrong on a mortise lock means the wrong bevel and latch orientation.
5) Will the MRX-A-05 drop into an existing ANSI mortise pocket and strike prep?
It uses a 1-1/4 x 8 inch stainless steel face plate and a 1-1/4 x 4-7/8 inch ASA strike, which are the standard ANSI mortise dimensions. If the door you're replacing already has a standard ANSI mortise pocket and ASA strike prep in the frame, the lock body and strike line up. The change you will still be cutting for is the arch trim footprint, which differs from lever rose or escutcheon prep.
6) What is a standard lever mortise classroom lock alternative to the TownSteel MRX-A-05 for a non-behavioral-health opening?
The MRX-A-05 is a Grade 1 classroom mortise lockset built around a ligature-resistant stainless steel arch trim for behavioral, mental and psychiatric healthcare openings. On a standard corridor or classroom door where ligature resistance is not required, the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. All three carry the same classroom function and Grade 1 rating; the difference is the trim style and the ligature-resistant construction.
7) Is there another ligature-resistant mortise option if the opening needs push/pull rather than a keyed classroom lock?
Yes. The TownSteel MRX-A-05 is a keyed classroom function with a single cylinder, so it locks and unlocks by key. If the opening calls for free passage instead, 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. Use the MRX-A-05 where the door must be secured by key and the 5PDN where the door is a passage opening with no locking requirement.
8) Can I get several MRX-A locksets keyed alike across a wing?
Yes. Keying is a required selection at order: keyed different (the standard), keyed alike for multiple locks on one key, or a specific key code if your facility already has a keyway and code on file. There is also a non-keyed option for functions that don't take a cylinder. For an SFIC house key system, take the SFIC prep version and set your own cores.
9) Is the MRX-A-05 heavy duty enough for a hospital corridor?
It's an ANSI Grade 1 mortise lock rated heavy duty, which is the top commercial grade and the level normally specified for institutional traffic. Grade 1 mortise construction is what a healthcare or education spec typically calls for on corridor and patient room doors.
10) Are the Alarm Lock Trilogy DL2700CR and DL3500CR direct substitutes for the TownSteel MRX-A-05?
They share the classroom function and Grade 1 rating but they are not equivalents. The MRX-A-05 is a mechanical, non-electronic lockset with a cylinder and ligature-resistant stainless arch trim, prepped for a 1-3/4 inch door. The Alarm Lock DL2700CR is a Trilogy T2 electronic mortise lock with a classroom function and weatherproof design, and the DL3500CR is a Trilogy electronic mortise lock with 300 user codes and classroom function; both are keypad locks listed for 1-5/8 inch to 1-7/8 inch doors. Choose the MRX-A-05 when the specification is a key-operated ligature-resistant lock and the Trilogy units when access is to be granted by user code.
11) If the opening needs storeroom rather than classroom function, what takes the place of the TownSteel MRX-A-05?
The MRX-A-05 is the classroom function in the ligature-resistant arch trim mortise family, where the outside lever is locked and unlocked by key. For a storeroom opening, where the outside trim stays locked at all times and entry is by key only, the Cal-Royal NM8080 is a heavy duty 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 with an Arcadia lever. Neither carries the ligature-resistant arch trim of the MRX-A-05.
12) Can I use a BEST 45H mortise lock body in place of the TownSteel MRX-A-05?
Not as a complete assembly. The MRX-A-05 is a full lockset supplied with the cylinder, a 1-1/4 inch by 8 inch stainless face plate, an ASA strike measuring 1-1/4 inch by 4-7/8 inch, and the 5-point ligature-resistant arch trim with tamper-resistant mounting screws. The BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA is a heavy duty mortise lockbody in intruder function. Those are lock bodies, so trim is specified separately, and neither is offered in the classroom function that the MRX-A-05 carries.
13) What is the difference between the TownSteel MRX-A-05 and the Sargent 7925 for a dormitory or patient room corridor door?
Both are Grade 1 heavy duty mortise locks. The MRX-A-05 is a classroom function with a single cylinder and 5-point ligature-resistant stainless arch trim intended for behavioral, mental and psychiatric healthcare openings. The Sargent 7925 is a dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. The deadbolt and projecting rose trim on the 7925 are the deciding point: on a patient room at risk, the arch trim of the MRX-A-05 is the ligature-resistant profile.
14) I need the same ligature-resistant look but on a privacy or restroom door instead of a classroom opening. What are my options?
The MRX-A-05 is the keyed classroom function with a single cylinder. For a privacy opening, the Cal-Royal NM8440 is a heavy duty 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 1-3/4 inch to 2 inch doors. Both are conventional lever and rose trim rather than the 5-point ligature-resistant arch trim, so confirm the trim profile against your facility's requirements before specifying either on a patient-accessible door.
15) Does the TownSteel MRX-A-05 work with a small format interchangeable core like the Cal-Royal NM8080?
Yes, if you order the right build. The MRX-A-05 is offered with a standard cylinder or with an SFIC prep less core, in 630 satin stainless steel, in left hand, left hand reverse, right hand and right hand reverse. The Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option, so a facility standardizing on SFIC can carry both, keeping in mind the NM8080 is storeroom function while the MRX-A-05 is classroom.
16) What finish does the TownSteel MRX-A-05 come in?
630 satin stainless steel, across every handing and both cylinder options. Satin stainless is the usual match for the other stainless trim, push plates and frames in a behavioral health build, so it'll sit consistently with existing hardware in most institutional settings.
17) Does the MRX-A-05 have any electronic access control or keypad?
No, it's a purely mechanical mortise lock, key operated. If you need credential or code access on a classroom door, electronic mortise options include the Alarm Lock DL3500CR, a Grade 1 classroom function electronic mortise lock with 300 user codes for 1-5/8 to 1-7/8 inch doors. Note that thickness range differs from the MRX-A's 1-3/4 inch.
18) Will a Schlage PM010 or L0170 work on a door where the TownSteel MRX-A-05 is specified?
They fit the same 1-3/4 inch door thickness but they do not do the same job. The MRX-A-05 is a keyed classroom function with a single cylinder. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock, and the L0170 is a Grade 1 non-keyed half dummy trim with no latching at all. Use those only where the opening is genuinely passage or dummy; neither will secure a classroom or patient room.
