Yes, and 1-3/4 inches is the only thickness the MRX-A is built for. It mounts on either a wood or a metal door, so the same lock covers both leaf types in a patient wing. If your openings are thicker or thinner than 1-3/4, this isn't the lockset for them.

It's a keyed hotel/motel function with a thumbturn on the inside. The key retracts the latch from outside, and the occupant can throw the T-turn from inside to shut out the guest-level key. The MRX-A-15 is single cylinder, so there's only one keyed side.

That's exactly what it's built for. The MRX-A carries a 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 sloped arch gives nothing to loop a cord over, and the tamper screws keep the trim from being removed with a common driver.

Yes. It's ordered as LH, LHR, RH, or RHR. Stand outside the door: if the hinges are on your left it's left hand, on the right it's right hand, and if the door swings toward you it's the reverse version. Getting this wrong on an arch trim lock means the trim sits wrong on the door, so pick the hand before you order.

Yes. Two cylinder builds are offered: standard cylinder, or SFIC prep less core if you're stamping your own cores into an existing facility system. The less-core version ships without a core, so order the core separately. A standard-cylinder MRX-A arrives with its cylinder included.

It uses 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 commercial mortise prep. If the door and frame already carry a standard ANSI mortise pocket and ASA strike cutout, the lock body and strike line up. The trim footprint is the part to check, since the ligature-resistant arch is larger than a rose.

The Marks USA MAR5PDN 5PDN is the closest peer for a ligature resistant opening. It is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. The difference is function: the MAR5PDN is a passage paddleset with no keyed control, while the MRX-A-15 is a Grade 1 keyed hotel/motel T-turn mortise lockset with a single cylinder and a 5-point ligature resistant stainless steel arch trim. Use the MAR5PDN where the door only needs a push/pull operation, and the MRX-A-15 where the opening needs key control plus an inside T-turn.

Keying is a required selection: keyed different (the standard), keyed alike across multiple locks, or a specific key code if you're matching an existing system. For a wing where staff carry one key, choose keyed alike and order the whole quantity on the same line so they cut to one bitting.

Grade 1, heavy duty, and rated commercial. That's the top ANSI/BHMA classification for mortise locksets and the level typically specified for high-traffic institutional openings.

The MRX-A-15 is a hotel/motel T-turn lock, so it isn't the right function for a classroom or storeroom. Among Grade 1 mortise locks on a 1-3/4 inch door, the Cal-Royal NM8070 is classroom function and the NM8080 is storeroom with an interchangeable core option; the Corbin Russwin ML2003 is also a Grade 1 classroom mortise lockset. None of those carry a ligature-resistant trim, so if the opening is in a behavioral unit stay with the MRX-A family.

That depends on whether you are keying or credentialing the room. The MRX-A-15 is a mechanical hotel/motel mortise lockset with a single cylinder and no electronics. If you want credential based access, the Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock. Note that neither of those carries the 5-point ligature resistant arch trim the MRX-A-15 uses, so on a patient room door the mechanical MRX-A-15 is the one built for that condition.

No. The Sargent 130KB is a standalone standard duty mortise thumbturn in the 8200 series, and the Sargent 130W is a mortise thumbturn with a round backplate in the 7800 series. Both are trim pieces for their own lock bodies, not a lockset. The MRX-A-15 is a complete Grade 1 hotel/motel mortise lockset with the T-turn integrated into a 5-point ligature resistant stainless steel arch trim and tamper resistant mounting screws, so the turn is part of the ligature resistant assembly and is not swapped out for a separate thumbturn.

The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock with rose trim and a single cylinder deadbolt, which suits a corridor opening that needs an exit function. The BEST 45HCAC is a heavy duty mortise lock body with public entrance function and field reversible operation for high traffic entries. The TownSteel MRX-A-15 is heavy duty Grade 1 as well, but it is set up as a hotel/motel T-turn lockset with the ligature resistant arch trim, which is the choice when the room is a patient room rather than a general corridor.

You can stay with the MRX-A-15. It is built in a standard cylinder configuration and in an SFIC prep less core configuration in satin stainless steel across left hand, left hand reverse, right hand and right hand reverse, with key different, keyed alike or key code keying. Among the peers, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset also offers an interchangeable core option, but it is a storeroom function on a standard lever, not a hotel/motel T-turn lock with ligature resistant arch trim.

Function and trim. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 series with an Arcadia lever, so the outside is always locked and retracted by key. The TownSteel MRX-A-15 is a Grade 1 heavy duty hotel/motel mortise lockset with a T-turn and a 5-point ligature resistant stainless steel arch trim in 630 satin stainless, supplied with a cylinder and tamper resistant mounting screws. A projecting lever like the Arcadia is generally not what you want on a patient room door.

630 satin stainless steel only, across every handing and cylinder build. That matches the satin stainless used on most institutional hardware, so it will sit alongside stainless push plates, hinges, and closers without a finish mismatch.

No, it's fully mechanical, keyed with a cylinder and a thumbturn. If the project calls for credential or keypad access on a mortise prep, that's a different family altogether, such as the Dormakaba Saffire LX-I-M002 RFID mortise lockset or a Schlage CO-100 standalone keypad mortise lock. Neither of those is ligature resistant.

Only if the opening does not need key control. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock and the Schlage L0170 is a Grade 1 heavy duty half dummy mortise lever trim, both for 1-3/4 inch doors. Neither locks. The MRX-A-15 shares the 1-3/4 inch door thickness and Grade 1 rating but is a keyed single cylinder hotel/motel lockset with a T-turn, supplied with a cylinder, so it is the one to use where the room has to secure.
