TownSteel MRX-S-L-14-630 – Frequently Asked Questions

1) Will the TownSteel MRX-L-14 mortise lock fit a 1-3/4 inch door?
Yes, and only 1-3/4 inches. The MRX-L-14 is listed for a 1-3/4 inch door thickness, which is the standard commercial door. Thicker doors (2 inch and up) are outside what this lockset covers, so for a heavier leaf you would need a lock body listed for a range, such as the Hager 3800 Series locks that cover 1-3/4 to 2-1/2 inches.
2) Does the MRX-L-14 mortise lock drop into an existing ANSI mortise prep?
It uses the standard ANSI prep. The strike is a 1-1/4 x 4-7/8 inch ASA strike and the lock face plate measures 1-1/4 x 8 inches in stainless steel. If the door and frame are already prepped for an ANSI/ASA mortise lock at 1-3/4 inch thickness, the pocket, face and strike cutout line up. The lever trim is what changes, so check your escutcheon or rose cutout against the trim you order.
3) What makes this lock ligature resistant, and where is it actually used?
The MRX-L uses a ligature-resistant stainless steel lever with no gap or projection to loop a cord over, plus tamper-resistant mounting screws so the trim cannot be removed with a common driver. It is intended for behavioral, mental and psychiatric healthcare facilities housing patients at risk. In those rooms it is the lever geometry, not the lock function, that is the reason to specify it.
4) What does the store door X levers function on the MRX-L-14 actually do?
The 14 is a store door function with a double cylinder, meaning it is keyed on both sides and the levers do not retract the latch when locked. Nobody gets through from either face without a key, so use it on a storage or utility room where free egress is not required by code for that opening. If you need the lever to always release from inside, a storeroom function like the Cal-Royal NM8080 or Accentra 8805FL is the pattern to look at instead.
5) Does the MRX-L-14 come with a cylinder, or can I use my own SFIC core?
Both routes are available. The standard cylinder build ships with the cylinder included. The SFIC prep version comes less core, so you supply and pin your own small format interchangeable core to match the facility keyway. Pick SFIC if the building is already on an SFIC system and your locksmith stocks the cores.
6) Is there another ligature-resistant mortise option if a behavioral health door needs push/pull rather than a lever?
Yes. The TownSteel MRX-L-14 uses a ligature-resistant stainless steel lever, either escutcheon or sectional trim. If the opening calls for no 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. The Marks unit is a passage paddle with no keyed control, while the MRX-L-14 is a keyed storeroom lock supplied with a cylinder.
7) What is an equivalent Grade 1 storeroom mortise lock to the TownSteel MRX-L-14 if ligature resistance is not required?
The TownSteel MRX-L-14 is a Grade 1 storeroom-function mortise lockset built around a ligature-resistant stainless steel lever with tamper-resistant mounting screws for behavioral and psychiatric healthcare openings. On a standard commercial opening where ligature resistance is not part of the spec, 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. All three hold storeroom function; the difference is the ligature-resistant trim and tamper-resistant fasteners on the MRX-L-14.
8) What should I use instead of the MRX-L-14 on a classroom door that needs classroom function?
The TownSteel MRX-L-14 is storeroom function, so the outside lever stays locked and the key retracts the latch. For a classroom opening, 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 for 1-3/4 inch doors. If the room needs a visual status indicator, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and steel escutcheon.
9) Should I order escutcheon or sectional trim on the MRX-L lever mortise lock?
Both are offered. Escutcheon (E) is a single long plate covering the lever and cylinder, which hides the old trim scars on a retrofit and gives a larger tamper-resistant footprint, so it is the usual pick for patient rooms. Sectional (S) uses separate rose and cylinder trim, leaves less surface on the door, and suits narrower stiles or a building already standardized on rose trim. The lock body and function are the same either way.
10) Can I get several of these mortise locks keyed alike for a facility?
Yes. Keying is a required selection: key different (KD) is standard, key alike (KA) ties multiple locks to one key, and a specific key code can be entered for special keying. For a wing of patient rooms on one staff key, choose KA and specify the quantity together on the order. Choose the SFIC less-core build instead if you want your own shop to key them into an existing system.
11) Will this mortise lockset work on a wood door, or is it metal frame only?
The MRX-L mounts on both wood and hollow metal doors, so the same part number works across a facility with mixed leaf construction. The prep is the ANSI mortise pocket with a 1-1/4 x 4-7/8 ASA strike in the frame in either case.
12) Is this a Grade 1 lock suitable for high traffic institutional use?
It is an ANSI Grade 1 heavy duty mortise lockset, the top commercial grade for cycle life and strength, in a commercial rather than residential build. That is the grade specifications call for on healthcare and institutional corridor and patient room openings.
13) Is there an electronic or access control version of this anti-ligature mortise lock?
No. The MRX-L-14 is a mechanical, key-operated lockset with no electronics, so it needs no power, wiring or credential system. If the opening has to run on access control, mortise options we carry include the Schlage CO-100 standalone keypad mortise lock and the BEST 45HW wired electromechanical mortise lock at 12V or 24V, neither of which is a ligature-resistant design.
14) I need a classroom or privacy function on the same doors, not store door. What else is there?
The 14 is double cylinder store door only. For other functions on comparable Grade 1 mortise bodies at 1-3/4 inch doors, we carry the Cal-Royal NM8070 classroom, NM8440 privacy with deadbolt, NM8050 office/entrance, and the Corbin Russwin ML2003 classroom. None of those are ligature-resistant trim, so on an at-risk patient opening stay within the MRX-L family and change the function code instead.
15) If the door needs keypad or credential access rather than a key, what mortise locks replace the MRX-L-14?
The TownSteel MRX-L-14 is a mechanical lock with no electronic components. For credential or code access on a mortise prep, the Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override and no deadbolt; the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors; and the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125 kHz proximity reader and a 3 hour fire rating. None of these carry the ligature-resistant lever and tamper-resistant screws of the MRX-L-14.
16) Will a BEST 45H mortise lock body substitute for the TownSteel MRX-L-14?
Not as a one-for-one. The MRX-L-14 is a complete Grade 1 storeroom lockset supplied with a cylinder, a 1-1/4 inch by 8 inch stainless face plate, and ligature-resistant lever trim in escutcheon or sectional form. The BEST 45HCAC is a heavy duty mortise lock body in public entrance function and the 45HCAINL is a heavy duty mortise lockbody with intruder function - both are lock bodies, so trim and cylinder are specified separately. Function also differs from storeroom.
17) What looks like a substitute for the MRX-L-14 but will not lock the door?
Several mortise-family items are trim or non-keyed only. The Schlage L0170 is a Grade 1 half dummy lever trim in dummy function, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Hager 3810E is a passage mortise lock with escutcheon and 2-3/4 inch backset. None of them secure the opening. The TownSteel MRX-L-14 is a keyed storeroom lockset supplied with a cylinder.
18) The MRX-L-14 is listed for 1-3/4 inch doors. What Grade 1 mortise locks cover thicker doors?
The TownSteel MRX-L-14 is specified for 1-3/4 inch door thickness. For a thicker leaf, the Hager 3810E and 3810S Grade 1 passage mortise locks cover 1-3/4 inch through 2-1/2 inch, as does the Hager 3850E Grade 1 office mortise lock with lever and escutcheon; the Baldwin 6301LS entry/apartment lever by lever mortise lock body is listed for 1-3/4 inch and over. Those are passage, office, and entrance/apartment functions rather than storeroom.
19) If a patient room needs privacy rather than keyed storeroom control, what mortise lock fits instead of the MRX-L-14?
The MRX-L-14 is storeroom function with a double cylinder keyed arrangement. For privacy, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, the Hager 3840S is a Grade 1 privacy mortise lock with 2-3/4 inch backset for 1-3/4 to 2 inch doors, and the Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors.
20) What is the difference between the TownSteel MRX-L-14 and the Command Access ML190 storeroom mortise lock?
Both are heavy duty storeroom-function mortise locks. The TownSteel MRX-L-14 is a mechanical Grade 1 lockset with no electronic components, ligature-resistant stainless lever trim, and a supplied cylinder. The Command Access ML190 Series is a motorized mortise lock with field selectable EL or EU operation on 24VDC, so it requires power and access control wiring to release the lever.
21) For a dormitory corridor door, is the MRX-L-14 the right function or is there a better mortise lock?
The MRX-L-14 is storeroom function, which keeps the outside lever locked at all times. For a dormitory or corridor opening where the occupant controls the deadbolt, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. Choose the MRX-L-14 where ligature-resistant trim and tamper-resistant mounting screws are required.
22) Can a mortise deadbolt be used in place of the MRX-L-14 storeroom lockset?
Only as an addition, not a replacement. The TownSteel MRX-L-14 is a lever-handled storeroom lockset with a 1-1/4 inch by 4-7/8 inch ASA strike, so it both latches and secures the opening. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, the Kaba Ilco 185 Series is a no-handing mortise deadbolt, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes for 1-5/8 to 1-7/8 inch doors. Deadbolts provide no latching and no lever operation.
