TownSteel MRX-A-08-630-RH – Frequently Asked Questions

1) Will the TownSteel MRX-A-08 mortise lock fit a 1-3/4 inch door, and does it work on wood as well as hollow metal?
The MRX-A-08 is built for 1-3/4 inch doors, and that is the only thickness it covers. It mounts on either a wood or a metal door, so the same part number works across a mixed opening set in one building. On a 1-3/4 inch hollow metal frame door with standard commercial prep this drops in; anything thicker or thinner is the wrong lock.
2) What does the 08 corridor function on a TownSteel MRX-A actually do at the door?
Corridor function, single cylinder. Key on the outside retracts the latch and controls the outside lever; the inside arch trim always retracts the latch for free egress. That is the pattern used on patient room and dormitory corridor doors, where staff key in from the hall and anyone inside can always get out. It ships with the cylinder included, so you are not sourcing one separately.
3) Is the TownSteel MRX-A safe for a behavioral health or psychiatric patient room door?
That is what it was built for. The MRX-A carries a 5-point ligature-resistant stainless steel arch trim, so there is no lever, knob, or gap that will hold a cord or strap. Tamper-resistant mounting screws keep a patient from taking the trim off the door. TownSteel lists it for behavioral, mental, and psychiatric healthcare facilities housing patients at risk. A standard lever mortise lock is not an acceptable substitute on those openings.
4) Will the MRX-A-08 mortise lock latch into the strike already in my frame?
The MRX-A-08 comes with a 1-1/4 inch by 4-7/8 inch ASA strike, which is the standard commercial strike prep in hollow metal frames. If your existing frame is cut for an ASA strike of that size, the new lock latches into it and you can reuse the prep. The lock face plate is 1-1/4 inch by 8 inch stainless steel, so the door edge mortise needs to match that standard mortise cutout as well.
5) How do I figure out the handing to order on a TownSteel MRX-A mortise lock?
Handing has to be specified, and there are four choices: LH, LHR, RH, and RHR. Stand outside the opening, on the key side. If the hinges are on your left it is left hand; on your right, right hand. If the door swings toward you rather than away, it is the reverse version, LHR or RHR. Get this wrong on a corridor door and the key side ends up on the patient side of the opening.
6) Can I get the TownSteel MRX-A prepped for our small format interchangeable core keyway?
Two cylinder choices, and they cover both approaches. Standard ships with the TownSteel cylinder installed and ready to key. SFIC Prep, Less Core comes prepped for a small format interchangeable core but with no core in it, so a facility already standardized on its own SFIC keyway drops in its cores and pins the whole building to one system. Both options are available in every handing.
7) What is the difference between a ligature-resistant arch trim mortise lock and a standard Grade 1 lever mortise lock?
The lock body work is comparable, the trim is the whole difference. The MRX-A uses a 5-point stainless arch trim with no projecting lever to anchor a ligature, plus tamper-resistant screws so it cannot be removed from the patient side. A conventional Grade 1 lever mortise such as the Cal-Royal NM8070 classroom or the Corbin Russwin ML2003 gives you a standard lever at the same Grade 1 level and the same 1-3/4 inch door thickness, and it is the right choice on an office, classroom, or back-of-house door. Use the arch trim only where patient risk is the reason.
8) Is there another ligature-resistant option if the opening needs push/pull rather than a keyed corridor lock?
The Marks USA 5PDN is the ligature-resistant alternative for that opening. It is a Grade 1 hospital passage mortise push/pull paddleset, described as ligature resistant and ADA compliant, in satin stainless steel. It is a passage device, so it does not lock; the TownSteel MRX-A-08 is a keyed corridor function with a single cylinder. Use the 5PDN on patient room or toilet doors that must never be secured against staff, and the MRX-A-08 where the corridor side must key.
9) What is the closest equivalent to the TownSteel MRX-A-08 corridor mortise lock from another manufacturer?
The Sargent 7925 is the nearest peer on function. It is a Grade 1 heavy duty mortise lock listed with a corridor/dormitory exit function, and it carries rose trim with a single cylinder deadbolt. The TownSteel MRX-A-08 is also Grade 1 heavy duty and corridor function, but it carries a 5-point ligature-resistant stainless steel arch trim and tamper-resistant mounting screws rather than rose trim. Where the opening is in a behavioral or psychiatric unit, the arch trim is the reason to stay with the MRX-A-08; on an ordinary dormitory corridor, the 7925 covers the same function with conventional trim.
10) Does a Grade 1 mortise lock from Cal-Royal or Accentra give the same patient-safety protection as the TownSteel MRX-A-08?
No. 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 from the 8800 Series. Both match the MRX-A-08 on grade, and the MRX-A-08 also offers an SFIC prep less core option. What they do not match is trim: the MRX-A-08 carries a 5-point ligature-resistant stainless steel arch trim and tamper-resistant mounting screws, which is what suits it to behavioral, mental, and psychiatric facilities housing patients at risk. A lever-trim storeroom lock does not serve that opening.
11) If I am ordering a dozen MRX-A locks for a patient wing, can they all run on one key?
Keying is a required selection on the MRX-A. Key Different is the standard, and each lock gets its own key. For a wing where staff should carry one key, choose Key Alike and the whole order is cut to a common key. If your facility already runs a keying system, Key Code lets you enter the specific code so the new locks match the master already in service. Non-keyed functions take the N/A option.
12) Is the TownSteel MRX-A a Grade 1 lock, and is it rated for high traffic?
ANSI Grade 1 and heavy duty, which is the top commercial classification and what a spec on an institutional corridor door normally calls for. Grade 1 mortise is the durability tier for doors that cycle constantly, so a behavioral health wing, a dorm corridor, or a hospital patient room is inside its intended service. It is a mechanical lock with no electronics.
13) Do I need to buy a cylinder, strike, or trim separately with the TownSteel MRX-A-08?
It is a complete lockset. Cylinder included on the Standard version, arch trim on both sides, tamper-resistant mounting screws, a 1-1/4 inch by 8 inch stainless face plate, and the 1-1/4 inch by 4-7/8 inch ASA strike. The one thing you supply is the core if you order the SFIC Prep, Less Core version, since that ships prepped but empty for a facility using its own keyway.
14) I want an electronic or card-access lock on my patient corridor doors. Is the MRX-A the right lock?
No. The MRX-A is fully mechanical, key operated only, with no electronics of any kind. For a credentialed opening, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader. Neither of those carries ligature-resistant trim, so on an at-risk patient room the mechanical arch trim lock is still the correct specification.
15) Can a TownSteel MRX-A replace an existing Grade 1 mortise lock without recutting the door?
If the door is 1-3/4 inches and already carries a standard mortise pocket with an ASA strike in the frame, the lock body and the 1-1/4 inch by 8 inch face plate go back into that prep. What changes is the trim: the 5-point arch trim covers a different footprint than a lever rose or an escutcheon, so plan on the old trim screw holes and rose diameter not lining up. That is a face-of-door patching question, not a re-mortise.
16) What is a simpler mortise lock for a door that does not need a cylinder at all?
For a non-keyed opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, the same thickness the TownSteel MRX-A-08 is built for. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock that is field reversible and carries a fire rating. The MRX-A-08 is a single cylinder keyed corridor lock and includes a cylinder, so a passage lock is the shorter order where nothing needs to key.
17) Is the Schlage L9092EU 03A a substitute for the TownSteel MRX-A-08 corridor lock?
They share the corridor function, are both heavy duty, and both are built for 1-3/4 inch doors, but they are not interchangeable. The Schlage 03A is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, so it needs power to the door and a means of control. The TownSteel MRX-A-08 is mechanical, not electronic. Choose the Schlage where the corridor side is tied to an access control system, and the MRX-A-08 where the opening runs on keys alone.
18) What Grade 1 mortise lock should be specified if the door needs privacy with a deadbolt instead of corridor function?
The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, matching the door thickness the TownSteel MRX-A-08 is built for. The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. The MRX-A-08 is a corridor function with a single cylinder, which does not give the occupant a privacy throw, so on bed and bath doors one of the privacy locks is the correct specification.
19) Can an electronic mortise lock replace the TownSteel MRX-A-08 on a 1-3/4 inch door?
Watch the door thickness before assuming it drops in. The Alarm Lock DL3500CR and DL2700CR are Grade 1 electronic mortise locks with classroom function, and both are listed for doors 1-5/8 inch to 1-7/8 inch. The Schlage CO-100 standalone electronic mortise lock is Grade 1 heavy duty with a keypad reader and a privacy function on 1-3/4 inch doors, which is the thickness the TownSteel MRX-A-08 is built for. The MRX-A-08 itself is mechanical, so any of these changes the opening from a keyed corridor lock to a credentialed one.
20) What is the difference between the TownSteel MRX-A-08 and a mortise lock body sold without trim, like the BEST 45H?
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 mortise lockbody with intruder function. Those are lock bodies, so trim is a separate order. The TownSteel MRX-A-08 is a complete lockset: it ships with the 5-point ligature-resistant arch trim, a cylinder, and tamper-resistant mounting screws, on a 1-1/4 by 8 inch stainless steel face plate with a 1-1/4 by 4-7/8 inch ASA strike. If the trim is already on the door and only the body is failing, a lock body is the right line item; if the whole opening is being built out, the complete lockset is.
21) If a facility is standardizing on one mortise family, which peers cover the other functions the TownSteel MRX-A-08 does not?
The Cal-Royal NM series runs the same Grade 1 heavy duty mortise platform across functions at 1-3/4 inch doors, matching the door thickness the MRX-A-08 is built for: NM8050 office/entrance with auxiliary deadlatch, NM8070 classroom, NM8080 storeroom, and NM8440 privacy with deadbolt. The Hager 3800 Series covers 3810S passage with rose and 3850E office with lever and escutcheon, both non-keyed variants on a 2-3/4 inch backset. The MRX-A-08 remains the corridor function piece and the one carrying the ligature-resistant arch trim for patient-occupied openings.
22) I need to match the satin stainless finish on the rest of the doors in my facility. What finish does the MRX-A-08 come in?
630 satin stainless steel, and that is the only finish on the MRX-A-08. It matches the 630 hardware already hanging on most institutional openings, and the trim itself is stainless steel rather than plated, so scuffs on a high-traffic patient corridor do not show a different metal underneath.
23) Are the Emtek mortise entrance locksets an alternative to the TownSteel MRX-A-08?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are all dummy function, meaning they operate nothing and mount for appearance and pull only. The TownSteel MRX-A-08 is a keyed corridor function lockset with a cylinder. If a dummy is what the inactive leaf needs, those Emtek trims serve it; they cannot secure a corridor opening.
