TownSteel MRX-S-L-04-630 – Frequently Asked Questions

1) Will the TownSteel MRX-L-04 mortise lock work on a behavioral health or psychiatric patient room door?
That is exactly what the MRX-L is built for. It is an ANSI Grade 1 mortise lock with a ligature-resistant stainless steel lever, suitable for behavioral, mental and psychiatric healthcare facilities housing patients at risk. Tamper-resistant mounting screws come with it so the trim cannot be easily removed from the patient side. The -04 designation is the Entrance/Office function, so the outside lever is locked or unlocked by key and the inside lever always retracts the latch for free egress.
2) What door thickness does the TownSteel MRX-L mortise lockset fit?
1-3/4 inches, which is the standard commercial door thickness. It mounts on either a wood or a metal door. If your openings are thicker than 1-3/4 inches, this is not the lock for that job.
3) Do I have to re-prep my frame, or will the MRX-L-04 drop into the existing strike cutout?
It uses a 1-1/4 inch by 4-7/8 inch ASA strike, the standard commercial mortise strike, so a frame already prepped for an ASA strike takes it without re-cutting. The faceplate is 1-1/4 by 8 inches in stainless steel, which is the normal mortise lock body prep, so an existing 1-3/4 inch door mortised for a standard mortise lock should accept it.
4) Does the TownSteel MRX-L-04 come with a cylinder, and can I use my own small format interchangeable core?
Two cylinder choices. The Standard option ships with a cylinder included. The SFIC Prep, Less Core option comes prepped for a small format interchangeable core but without the core, so you supply and keep control of your own SFIC to match the rest of the facility. It is a single cylinder function, keyed outside only.
5) Can I get a run of these TownSteel mortise locks keyed alike for a whole wing?
Yes. Keying is a required selection: KD key different is the standard, KA key alike puts multiple locks on one key, and Key Code lets you specify an existing key code so new locks work on the keys already in your maintenance crew's hands. If you are standardizing an SFIC system instead, order the SFIC prep less core version and key the cores yourself.
6) I need a ligature-resistant lock but the opening takes a push/pull, not a lever. What should I use instead of the MRX-L-04?
The Marks USA 5PDN is the alternative for that opening. It is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant, in satin stainless steel. Because it is a passage paddleset it does not lock, so it suits doors that only need latching. The MRX-L-04 is a keyed entrance/office lever lockset with a single cylinder, so if the door has to be secured, the lever lock is the one that does it.
7) What is the closest equivalent to the TownSteel MRX-L-04 in a standard entrance/office mortise lock?
The Cal-Royal NM8050 is the nearest match on function and grade: it is a Grade 1 heavy duty entrance/office mortise lockset for 1-3/4 inch doors, the same function, grade and door thickness the MRX-L-04 carries. The difference is the trim. The MRX-L-04 uses a ligature-resistant stainless steel lever with tamper-resistant mounting screws, intended for behavioral, mental and psychiatric healthcare openings where patients are at risk. The NM8050 is a conventional lever lockset and adds an auxiliary deadlatch. On an ordinary office or corridor door the NM8050 covers the same function; on a patient room door the ligature-resistant trim is the reason to stay with the MRX-L-04.
8) Should I order escutcheon or sectional trim on the TownSteel MRX-L?
Both are offered on the MRX-L in 630 satin stainless. The E escutcheon is a single full-length plate covering the lever and cylinder, which hides more of the door face and any old prep scarring from a lock you removed. The S sectional uses separate roses for the lever and cylinder, so it shows less hardware on the door. On retrofits over an existing escutcheon-trim lock, the E option is the safer cover. Functionally the lock body is the same either way.
9) What is the difference between the MRX-L-04 and a classroom or storeroom mortise lock?
Function is the difference. The MRX-L-04 is Entrance/Office: the outside lever can be left unlocked for normal traffic and locked by key when you want it secure, which suits offices, staff rooms and unit entry doors. If you need the outside lever permanently locked and key-only, that is a storeroom function, like the Cal-Royal NM8080 or the Accentra 8805FL. For a door that must be locked or unlocked from outside by key only while the inside always exits, look at a classroom function such as the Cal-Royal NM8070 or Corbin Russwin ML2003. Only the MRX-L carries the ligature-resistant lever.
10) Is the TownSteel MRX-L rated for high traffic institutional doors?
It is an ANSI Grade 1 heavy duty commercial mortise lock, the top grade, which is what you want on hospital, school and multi-family corridor doors that cycle all day. The lever and trim are stainless steel and the mounting screws are tamper-resistant.
11) If I want the same opening on a credential or keypad instead of a key, what replaces the MRX-L-04?
The MRX-L-04 is a mechanical lockset with no electronics. For credentialed access on a mortise prep, the Schlage CO-100 is a standalone electronic mortise lock with a keypad reader, Grade 1, heavy duty, for 1-3/4 inch doors, and the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes for doors 1-5/8 to 1-7/8 inches. Both change the door prep and power considerations, and neither is described with the ligature-resistant stainless lever and tamper-resistant screws the MRX-L-04 carries for at-risk patient areas.
12) What is the alternative to the MRX-L-04 if the door needs a bathroom or privacy function?
Two Grade 1 privacy mortise locksets cover that opening: the Cal-Royal NM8440, a privacy/bed/bath lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S, a Grade 1 privacy/bed/bath mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches. The MRX-L-04 is entrance/office with a single cylinder, so it is keyed rather than privacy-only. Note that neither privacy lock is described as ligature resistant, so for a patient toilet or bath in a behavioral setting the MRX-L-04 trim is what carries that characteristic.
13) Can I use a storeroom mortise lock in place of the MRX-L-04?
Only if the opening is meant to stay locked. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Storeroom trim keeps the outside lever locked at all times and requires a key on every entry. The MRX-L-04 entrance/office function lets the outside lever be left unlocked for normal use, which is usually what an office or patient corridor door wants.
14) Will a Baldwin 6301LS mortise lock work as a replacement for the MRX-L-04?
They are not interchangeable in the same application. The Baldwin 6301LS is an entry/apartment lever by lever mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over, a decorative residential-style lock body. The MRX-L-04 is a commercial Grade 1 heavy duty stainless steel lockset with a 1-1/4 by 8 inch stainless face plate and a 1-1/4 by 4-7/8 inch ASA strike, sold as a complete lockset with cylinder and ligature-resistant lever trim. Backset and trim differ, so a swap would require confirming the existing mortise pocket and prep.
15) Can I buy just a mortise lock body and reuse my existing trim instead of the MRX-L-04?
Yes, if the trim on the door is staying. The BEST 45HCAC is a heavy duty mortise lock body in the 45H series with public entrance function and field reversible operation, and the 45HCAINL is a heavy duty 45HCA lock body with intruder function. Those are lock bodies sold to pair with separate trim. The MRX-L-04 is a complete lockset that includes the cylinder and its ligature-resistant lever trim in escutcheon or sectional form, so it is the right call when the trim itself is what you are changing.
16) My opening needs a dormitory or corridor function with a deadbolt. What should I look at instead of the MRX-L-04?
The Sargent 7925 covers that. It is a Grade 1 heavy duty corridor/dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. The MRX-L-04 is an entrance/office single cylinder lockset without a deadbolt, and its trim is a ligature-resistant stainless lever in escutcheon or sectional form rather than a rose. Choose the 7925 where the specification calls for a deadbolt at a dorm or corridor door.
17) What finish does the TownSteel MRX-L anti-ligature mortise lockset come in?
630 satin stainless steel is the only finish, on both the escutcheon and sectional trims. That is the standard institutional finish, so it will match existing 630 hinges, closers and push plates on healthcare and school openings without a special order.
18) Is a passage mortise lock like the Schlage PM010 or Falcon MA101 an option instead of the MRX-L-04?
Only for openings that never need to lock. 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 fire rated mortise passage lock with field reversible operation. Neither takes a key. The MRX-L-04 is single cylinder keyed and ships with the cylinder, and it is ordered with a keying selection of key different, key alike or a specific key code, so it is the choice wherever the door has to secure.
19) Is a dummy mortise trim such as the Schlage L0170 a substitute for the MRX-L-04 on an inactive leaf?
For an inactive leaf, yes, and that is what it is for. The Schlage L0170 is a Grade 1 heavy duty non-keyed half dummy mortise lever trim for 1-3/4 inch doors in the L Series, with no latch and no locking. The MRX-L-04 is a working Grade 1 lockset with a latch, a single cylinder and an ASA strike, so it is the one to use on any leaf that actually operates.
