The MRX-A-41 is a single dummy, non-keyed function. It does not latch or lock anything. It mounts on one face of the door as a pull only, typically on the inactive leaf of a pair or on a door held closed by other means. If you need a working ligature-resistant mortise lock on a patient room, you want a keyed or privacy function from the MRX-A line instead of the 41.

Both are Grade 1 non-keyed dummy mortise trims for 1-3/4 inch doors and both are heavy duty. The difference is the trim itself: the L0170 is a lever dummy on the Schlage L Series, while the MRX-A-41 carries a 5-point ligature-resistant stainless steel arch trim with tamper-resistant mounting screws and is intended for behavioral, mental, and psychiatric facilities housing patients at risk. On a standard office or closet door either works; on a patient room door the arch trim is what removes the lever as a tie-off point.

For behavioral health doors 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 MRX-A-41 is also Grade 1 and non-keyed, but it is a single dummy with 5-point ligature-resistant stainless steel arch trim, so it provides a fixed pull with no latch operation, while the 5PDN is a passage paddle that actually retracts a latch. Choose the MRX-A-41 for the inactive leaf or pull-only side and the 5PDN where the door has to latch and be pushed open.

The MRX-A-41 is a dummy function with no latch, so it cannot operate a door. Where a non-keyed operating lock is required, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating. If the opening needs keyed control instead, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors. The MRX-A-41 is also listed for 1-3/4 inch doors, so the door prep thickness matches across all three.

Watch for two in particular. The Schlage PC10 is a Grade 1 passage lock for 1-3/4 inch doors, but it is cylindrical, so it needs a bored prep rather than the mortise pocket the MRX-A-41 uses. The Falcon MESC600DT is a dummy escutcheon lever trim, but it is trim for M9900 Series exit devices, not a mortise lockset. The MRX-A-41 is a mortise lock with a 1-1/4 by 8 inch stainless steel face plate and a 1-1/4 by 4-7/8 inch ASA strike, which is the prep to verify before ordering any of the three.

The MRX-A-41 carries the same mortise case prep as the rest of the MRX-A family: a 1-1/4 by 8 inch stainless steel face plate and a 1-1/4 by 4-7/8 inch ASA strike. That matters because the door and frame get cut to one standard prep across the whole unit, so a dummy opening and a locked opening are machined identically and you can swap functions later without re-prepping the door.

It is an ANSI Grade 1 mortise lock, heavy duty, commercial rated. Grade 1 is the top ANSI/BHMA durability tier and the one usually specified for hospital and institutional corridors.

They share the dummy function but not the application. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan are dummy mortise entrance locksets in decorative residential trim styles. The MRX-A-41 is a commercial Grade 1, heavy duty dummy with a ligature-resistant stainless steel arch trim and tamper-resistant mounting screws for at-risk patient areas. Specify the Emtek trims for residential and decorative openings and the MRX-A-41 where ligature resistance and a commercial grade are called out.

The MRX-A-41 is non-keyed dummy trim, so corridor and classroom-type doors need a keyed or function lock beside it. Grade 1 mortise options for 1-3/4 inch doors include the Corbin Russwin ML2003 classroom lockset, the Cal-Royal NM8070 classroom lockset with auxiliary deadlatch, and the Cal-Royal NM8440 privacy lockset with deadbolt for bed and bath. The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock with rose trim and a single cylinder deadbolt. None of these carry the MRX-A arch trim, so confirm the trim style the facility standard requires.

No, and the two are not interchangeable in function. The MRX-A-41 is a mechanical, non-electronic dummy trim with no latch and no credential. Electronic mortise locks such as the Schlage CO-100 standalone keypad lock with privacy function, the Dormakaba E-Plex E5086 pushbutton and card lock, and the Schlage LEMD-GRW wireless mortise lock with 125kHz proximity reader all operate a latch under access control. If an opening was specified with the MRX-A-41, it was specified as a pull-only leaf; converting it to an electronic lock changes the door function and the prep.

One finish: 630, satin stainless steel. That is the standard institutional finish, so it lines up with satin stainless push plates, hinges and closers already on most behavioral health openings. The trim itself is stainless steel, not plated.

No, the MRX-A ships with a cylinder. On the 41 dummy that is trim hardware rather than a working keyed function, since the 41 is non-keyed.

No, it is purely mechanical, with no electrified option on the dummy. If the opening needs credential access, the mortise alternatives we carry include the Schlage CO-100 standalone electronic mortise lock and the Dormakaba E-Plex 2066 pushbutton keyless mortise lock, though neither is a ligature-resistant trim.
