Both. The MRX-A-04 ligature-resistant mortise lockset mounts on wood or metal doors, and it is built for 1-3/4 inch door thickness. If your openings are anything other than 1-3/4 inch, this is the wrong lock for them.

You pick one of four: left hand, left hand reverse, right hand, or right hand reverse. Reverse handing applies where the door swings out toward you (typical of a patient room pulling into a corridor), so check the swing direction from the secure side before you order. Every handing is offered in 630 satin stainless steel.

It should. The MRX-A ships with a 1-1/4 inch by 4-7/8 inch ASA strike, which is the standard commercial mortise strike prep, and the lock face plate is 1-1/4 inch by 8 inch stainless. If your frame is already cut for a standard ASA mortise strike and the door is prepped for a 1-1/4 x 8 face, the swap is straight across.

Entrance/office function: the outside trim can be locked or unlocked, key retracts the latch from outside, and the inside trim always retracts the latch for free egress. It is a single-cylinder keyed lock, so there is no key required on the inside. That is the right function for a staff office or a unit entry where you want the door left on latch during the day and secured after hours.

That is what it was built for. The MRX-A is an ANSI Grade 1 mortise lock with 5-point ligature-resistant stainless steel arch trim and tamper-resistant mounting screws, and TownSteel specifies it for behavioral, mental, and psychiatric healthcare facilities housing at-risk patients. The arch shape sheds a cord or strap rather than holding it, which a standard lever will not do.

Two ways to order it. The Standard cylinder option ships with the cylinder included. The SFIC Prep, Less Core option comes prepped for a small format interchangeable core but no core in the box, which is what you want if your facility is already on an SFIC keying system and your locksmith pins its own cores.

The MRX-A-04 is a keyed single-cylinder entrance/office mortise lockset with ligature-resistant arch trim. Where the opening calls for a non-keyed push/pull instead, the Marks USA 5PDN is the alternative: a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. It is a passage device, so it provides no key control at that opening, while the MRX-A-04 keeps single-cylinder keyed operation.

The MRX-A-04 is a Grade 1 entrance/office mortise lockset for 1-3/4 inch doors, built with a 5-point ligature-resistant stainless steel arch trim for behavioral and psychiatric settings. On a standard corridor or office door where ligature resistance is not part of the spec, the Cal-Royal NM8050 is the direct functional match: it is a heavy duty Grade 1 entrance/office mortise lockset for 1-3/4 inch doors with an auxiliary deadlatch, using conventional lever trim instead of the arch trim.

The TownSteel MRX-A-04 is built for entrance/office function only. For a classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset for 1-3/4 inch doors with an auxiliary deadlatch. Where the classroom door also 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. None of those three carries the ligature-resistant arch trim the MRX-A-04 uses.

The MRX-A-04 is a non-electronic mechanical mortise lockset with single-cylinder key control. Electronic mortise options include the Alarm Lock DL3500CR, a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100 standalone electronic mortise lock, Grade 1 heavy duty with a keypad reader in privacy function for 1-3/4 inch doors. Both replace key-only access with code-based credentials and neither is built with ligature-resistant arch trim, so for a behavioral health opening specified for ligature resistance the MRX-A-04 is the one that meets that requirement.

The MRX-A-04 is entrance/office function, which is not a privacy configuration. For a bed or bath 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 3800 Series Grade 1 privacy mortise lock with 2-3/4 inch backset for 1-3/4 to 2 inch doors. Neither carries the ligature-resistant arch trim, so on a behavioral health bathroom confirm the trim against the same requirement the MRX-A-04 was chosen for.

Yes. Keying is a required selection at order: keyed different (the standard), keyed alike for a group of locks that should share one key, or a specific key code if you are matching an existing system. Give the key code in the text field when you choose that option. Non-keyed is also listed for functions that do not take a cylinder.

Both are Grade 1 mortise locks, but the function differs. The MRX-A-04 is entrance/office, so the outside trim can be locked and unlocked by the occupant. The Accentra 8805FL is a Grade 1 storeroom function mortise lock in the 8800 Series with an Arcadia lever, where the outside stays locked at all times and requires a key for entry. The Cal-Royal NM8080 is another Grade 1 storeroom mortise lockset for 1-3/4 inch doors, offered with an interchangeable core option. The MRX-A-04 is the only one of the three with a 5-point ligature-resistant stainless steel arch trim.

Only if the opening truly needs no key control. The MRX-A-04 is single-cylinder keyed in entrance/office function. Passage alternatives include the Falcon MA101, a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Schlage PM010 Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Hager 3810S, a 3800 Series Grade 1 passage mortise lock with rose trim and 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors. All three latch only and cannot be locked, and none uses the ligature-resistant arch trim.

The MRX-A-04 is a complete lockset that includes the cylinder and the 5-point ligature-resistant stainless steel arch trim with tamper-resistant mounting screws. If the existing trim is staying and only the chassis is being replaced, the BEST 45H is a heavy duty mortise lock body in public entrance function with field reversible operation, and the BEST 45HCA is a heavy duty mortise lockbody in intruder function. Those are lock bodies supplied without the arch trim, so they do not deliver the ligature-resistant package.

Several mortise-family items are trim or components rather than locksets. The Sargent 130KB is a standard mortise thumbturn in the 8200 Series and the Sargent 130W is a mortise thumbturn with a round backplate in the 7800 Series. The Schlage L0170 is half dummy trim, a Grade 1 non-keyed mortise lever with no latching function. The Emtek 3102 Memphis mortise entrance lockset is a dummy as well. The MRX-A-04, by contrast, is a complete single-cylinder keyed entrance/office mortise lockset supplied with its cylinder and ligature-resistant arch trim.

The MRX-A-04 is a single-cylinder entrance/office mortise lockset and does not carry a deadbolt. For a corridor or dormitory opening needing exit function with a deadbolt, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. It uses conventional rose trim rather than the ligature-resistant arch trim of the MRX-A-04.

Not by itself. The MRX-A-04 entrance/office lockset can be ordered with a standard cylinder or with SFIC prep less core, in any of the four handings, so it drops into an SFIC keying program. The Cal-Royal NM8080 storeroom mortise lockset is also offered with an interchangeable core option, but it is storeroom function rather than entrance/office and does not use ligature-resistant arch trim. Choose on function and trim requirement first, since both paths support interchangeable core.

No, it is purely mechanical, key and trim only. If the opening needs credential access, the mortise platforms to look at are electronic units like the Schlage CO-100 standalone keypad mortise lock or the BEST 45HW wired electromechanical mortise lock. None of those carry the MRX-A's ligature-resistant arch trim.

630 satin stainless steel is the only finish offered on the MRX-A-04 arch trim lockset. That is the standard institutional stainless finish, so it lines up with satin stainless closers, hinges, and push plates already common in healthcare corridors.
