TownSteel MRX-S-L-46-630 – Frequently Asked Questions

1) What door thickness does the TownSteel MRX-L-46 anti-ligature mortise lock fit?
The MRX-L-46 is built for 1-3/4 inch doors, which is the standard commercial door thickness. It mounts on either wood or metal doors. If your openings are thicker or thinner than 1-3/4, this is not the lockset for them.
2) What does the -46 function actually do on a patient room door?
It is institutional privacy with a key locked feature. The occupant can secure the door for privacy, and staff can override from the outside with a key, so a room can never be locked against the people who need to get in. That is the reason this function shows up on behavioral health and psychiatric patient rooms rather than a plain privacy set with a thumbturn emergency release.
3) Will the MRX-L-46 drop into my existing ASA strike prep?
The lock ships with a 1-1/4 x 4-7/8 inch ASA strike and a 1-1/4 x 8 inch stainless steel face plate, which is the standard mortise prep. If your frames are already cut for an ASA strike and your doors carry a standard mortise pocket with an 8 inch face, the swap is straightforward. Pull the old lock and check the face plate size before you commit a whole floor to it.
4) Does the MRX-L-46 come with a cylinder, or do I need to supply one?
Two ways to order it. The Standard cylinder version arrives with the cylinder included. The SFIC Prep, Less Core version is prepped for a small format interchangeable core but ships without the core, so your locksmith or facility keying program supplies and pins it. Order SFIC prep if your building is already standardized on interchangeable cores.
5) Can I key a run of these MRX-L-46 locks alike across a unit?
Yes. Keying is a required selection: KD keyed different is standard, KA keys multiple locks alike, and Key Code lets you specify a particular code to match an existing system. If you are ordering a batch for one wing and want staff carrying a single key, choose KA on every lock in that order.
6) What makes this lock ligature resistant compared with a normal Grade 1 mortise lever?
The lever itself is a ligature-resistant stainless steel shape that will not hold a cord or strap, and the trim is fastened with tamper-resistant mounting screws so a patient cannot back the plates off the door. A conventional Grade 1 lever lock gives the same durability but leaves a lever that can be looped, which is why it does not belong on an at-risk patient room.
7) Can I use a standard Grade 1 privacy mortise lock instead on a behavioral health room?
Not if the room houses at-risk patients. A set like the Cal-Royal NM8440, a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, is a fine bed/bath privacy lock but has no ligature-resistant trim. Same door thickness, same grade, very different application. Use the MRX-L-46 where ligature resistance is part of the spec and save the conventional privacy set for staff restrooms and offices.
8) What is the closest ligature-resistant alternative to the TownSteel MRX-L-46 mortise lockset?
The Marks USA 5PDN is the nearest ligature-resistant peer. It is a Grade 1 hospital passage mortise push/pull paddleset described as ligature resistant, ADA compliant, and satin stainless steel. The functional difference matters: the 5PDN is a passage paddleset with no locking, while the MRX-L-46 is an institutional privacy lock with a key locked feature, single cylinder, on a stainless steel anti-ligature lever. Use the 5PDN on a patient corridor or utility opening that must stay free-swinging, and the MRX-L-46 where staff need to secure or override the room.
9) If the opening does not need anti-ligature trim, what Grade 1 privacy mortise lock can be used instead of the MRX-L-46?
Two standard-trim privacy mortise locks cover that case. 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 doors 1-3/4 to 2 inches. Both are conventional privacy sets; neither carries the ligature-resistant stainless lever and tamper-resistant mounting screws that make the MRX-L-46 suitable for behavioral and psychiatric rooms.
10) Should I order escutcheon or sectional trim on the MRX-L anti-ligature lockset?
Both are offered, in 630 satin stainless. The E escutcheon is a single full plate covering the lock area, which hides more of the door face and suits retrofits where the old trim left marks or extra holes. The S sectional uses separate roses at lever and cylinder for a lighter look. Security and lever function are the same either way, so pick on what the door face needs.
11) Is this lockset heavy duty enough for a hospital corridor or patient room?
It is an ANSI Grade 1 heavy duty mortise lock, the top commercial grade and the one specified for high-traffic institutional openings. Grade 1 mortise is what a healthcare facility standardizes on for patient rooms, corridors, and utility doors.
12) I need a ligature resistant mortise lock but the door takes a push/pull, not a lever. What else is there?
For an opening that calls for a paddle instead of a lever, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless. The MRX-L-46 is the lever answer with a keyed privacy function; the Marks paddleset is passage only, so it will not give you the key locked privacy the -46 provides.
13) We need classroom function instead of privacy on the same institutional doors - what mortise lock should we order?
For classroom function in a Grade 1 mortise body, the Cal-Royal NM8070 is a heavy duty classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset, also 1-3/4 inch. Both use conventional lever trim rather than the ligature-resistant stainless steel lever of the MRX-L-46, so they suit administrative and teaching areas rather than patient rooms.
14) What mortise lock should I use if the bathroom door needs privacy with electronic access control rather than a key override?
The Schlage CO-100-MS-40-KP is a standalone electronic mortise lock in privacy function with a keypad reader, Grade 1, heavy duty, for 1-3/4 inch doors - the same door thickness the MRX-L-46 is built for. The tradeoff is power and credential management: the CO-100 is an electronic keypad lock, while the MRX-L-46 is a mechanical single-cylinder set with no electronics, keyed KD, KA, or to a supplied key code.
15) Is the BEST 45HCA intruder function lockbody an equivalent to the MRX-L-46?
No. The BEST 45HCAINL is a heavy duty mortise lockbody with intruder function, sold as a lock body - trim and cylinder are separate line items. The MRX-L-46 ships as a complete institutional privacy lockset with a ligature-resistant stainless steel lever, escutcheon or sectional trim, and a cylinder included. If you are building from a lockbody up, the 45HCAINL or the 45HCAC public entrance body are the right starting points; if you need a finished ligature-resistant opening, they are not a drop-in.
16) We need a storeroom mortise lock to pair with MRX-L-46 privacy sets on the same floor - what are the options?
The Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. The NM8080's IC option lines up with the MRX-L-46's SFIC prep, less core, build if you are keying a facility on small format cores; both use conventional lever trim rather than a ligature-resistant lever.
17) Can I use the Sargent 7925 dormitory lock on patient rooms instead of the MRX-L-46?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. It suits corridor and dormitory openings in student housing. For behavioral, mental, and psychiatric rooms housing patients at risk, the MRX-L-46 is the one built for it, with a ligature-resistant stainless steel lever and tamper-resistant mounting screws; the 7925 uses conventional rose trim and adds a deadbolt.
18) Is the MRX-L-46 an electronic or access-control lock?
No, it is fully mechanical, key and lever only. If the opening needs credentials or audit trail, that is a different product entirely, for example the Schlage CO-100 standalone electronic mortise lock in privacy function with a keypad reader, Grade 1 heavy duty for 1-3/4 inch doors. But no electronic mortise lock in that group carries the anti-ligature trim this one does.
19) What finish does the MRX-L anti-ligature lockset come in?
630 satin stainless steel, on every trim and cylinder combination. That is the standard institutional finish, so it will match existing 630 hinges, closers, and push plates on the same openings. No other finish is offered in this series.
20) Will the Alarm Lock Trilogy DL2700CR fit the same doors as the MRX-L-46?
Not on the same door thickness. The Alarm Lock DL2700CR is a Grade 1 Trilogy T2 electronic mortise lock in classroom function rated for doors 1-5/8 to 1-7/8 inches, as is the DL3500CR. The MRX-L-46 is specified for 1-3/4 inch doors, which falls inside that band, but the Trilogy sets are keypad electronic classroom locks, not mechanical institutional privacy locks, and carry no ligature-resistant trim.
21) What is the difference between the MRX-L-46 and a passage mortise lock like the Falcon MA101 or Schlage PM010?
Function. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock, fire rated, with field reversible operation, and the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. Neither locks - the lever always retracts the latch. The MRX-L-46 is an institutional privacy set with a single cylinder key locked feature so staff can secure or release the room.
