No latch, no lock, no moving parts. The MRX-A-72 is a dummy trim set, non-keyed, with a ligature-resistant arch trim on both faces of the door. It gives you something to pull on and nothing to operate. Use it on the inactive leaf of a pair, on a closet or chase door held by a ball catch or magnetic catch, or anywhere you want the openings in a behavioral health unit to look and feel identical without adding a lock. If the door needs to latch, this is the wrong part.

Yes, and only 1-3/4 inches. The MRX-A-72 is a single-thickness device, so thicker doors and 1-3/8 inch interior doors are out. It mounts on wood or metal, which covers most patient room and corridor leaves in a behavioral unit.

The trim is a 5-point ligature-resistant stainless steel arch, sloped so a cord or sheet slides off rather than catching, with no lever, no hook, and no projecting return. It is held on with tamper-resistant mounting screws so a patient cannot back the trim off the door with a improvised tool. TownSteel built the MRX-A for behavioral, mental and psychiatric facilities housing at-risk patients, and the dummy version lets you carry that same trim onto the doors that do not need a lock.

Yes. The MRX-A-72 is a mortise-prepped trim set, not a surface-applied pull, and it uses the same door prep as the keyed MRX-A functions: a 1-1/4 x 8 inch stainless steel face plate on the door edge. That is what lets you run one prep across an entire unit and change function by changing the lock, rather than re-prepping doors later. If the leaf is only bored for a cylindrical lock, this will not drop in.

If the door cannot take a mortise pocket, the MRX-A-72 is the wrong direction. For a ligature-resistant opening from another brand, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless, though that one is a passage function and operates. Among plain dummy trims, the Schlage L0170 is a Grade 1 mortise half dummy for 1-3/4 inch doors, heavy duty but conventional lever trim with no ligature resistance. On a psychiatric unit that difference is the whole point, so do not swap one for the other on patient-side doors.

The Schlage L0170 is the closest Schlage counterpart for a non-keyed mortise dummy trim. It is a Grade 1, heavy duty mortise dummy for 1-3/4 inch doors, the same door thickness the MRX-A-72 is built for, and the same Grade 1 rating. The difference is the trim: the L0170 is a half dummy lever trim, while the MRX-A-72 is a back to back arch trim set with a 5-point ligature-resistant stainless steel arch on both faces and tamper-resistant mounting screws. For a patient room in a behavioral health unit, the arch trim is the reason to specify the MRX-A-72; for a standard corridor or closet pull, the L0170 covers it.

The Marks USA 5PDN is the other ligature-resistant option in the same class. It is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant, in satin stainless steel. Both it and the TownSteel MRX-A-72 are Grade 1 and finish in satin stainless steel. The operating difference decides it: the 5PDN is a push/pull paddle that actually retracts a latch for passage, while the MRX-A-72 is a dummy with no latch at all, used where the door needs a pull on both faces and holds closed by other means. If the opening has to open and close by hand, the paddleset is the one; if it is a fixed or magnetically held leaf, the dummy is.

A dummy has no latch, so if the leaf has to stay shut on its own you need a passage function instead. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, the same door thickness the TownSteel MRX-A-72 covers. The Falcon MA101 is another route, a Grade 1 heavy duty mortise passage lock, fire rated, field reversible. Both give a latch that retracts with the trim; the MRX-A-72 gives the ligature-resistant arch on both faces but leaves the door unlatched.

Grade 1, heavy duty, and specified as commercial. For an MRO or facilities buyer standardizing a behavioral unit, that is the top ANSI/BHMA operational grade for door hardware, and it is the level institutions normally write into a spec for patient-occupied corridors.

The MRX-A series works with a 1-1/4 x 4-7/8 inch ASA strike, which is the standard ANSI frame prep on commercial hollow metal. On the MRX-A-72 dummy there is no latch to catch, so the strike is not doing any work. It matters in two places: the frames on your keyed MRX-A openings need that prep, and if a dummy door later gets converted to a latching function the frame is already cut for it.

Back to back means trim on both faces of the door, which is what the MRX-A-72 gives you. A half dummy, like the Schlage L0170, puts trim on one side only. Pick back to back when both sides of the opening get used or need to look consistent, such as an inactive leaf in a corridor pair. Pick a half dummy for a closet or a door only ever pulled from one side. Ordering the wrong one leaves you a bare face plate on the other side of the door.

That is the reason to buy it. The MRX-A family shares one mortise body footprint and one arch trim across functions, so a dummy leaf sits beside a keyed or privacy opening with the same 1-3/4 inch door prep, the same 1-1/4 x 8 inch face plate cut, the same 630 satin stainless trim, and the same tamper-resistant screws. A property manager or facilities lead standardizing a wing gets identical-looking doors and one set of spare trim. Mixing in a conventional lever dummy breaks both the appearance and the ligature resistance.

No handing to call out. With no latch and identical arch trim on both faces, the MRX-A-72 installs the same on a left or right hand door. That is one less field error on a large order, and it means a single part number covers every dummy opening in the building.

The Dormakaba E-Plex E5086 is the back to back option with access control: a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back to back configuration. The TownSteel MRX-A-72 is also a back to back set and also Grade 1, but it is non-electronic and non-keyed, so it controls nothing. Where a behavioral unit needs staff-only entry on both faces, the E5086 carries the credential; where the opening only needs matching pulls with a ligature-resistant profile, the MRX-A-72 does that without any power or programming.

They share the word dummy and nothing that matters on a patient door. The Emtek 3106 Manhattan, 3104 Hamilton, 3102 Memphis and 3019 Brisbane are all mortise entrance locksets in dummy function, decorative residential trim in named design series. The TownSteel MRX-A-72 is a Grade 1 commercial mortise set with a 5-point ligature-resistant stainless steel arch trim on both faces and tamper-resistant mounting screws, in 630 satin stainless steel. If a spec calls for ligature resistance or a Grade 1 commercial rating, the Emtek dummies do not answer it.

The Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, and the NM8070 is the Grade 1 classroom version at the same 1-3/4 inch thickness. Corbin Russwin ML2003 is another Grade 1 classroom mortise at 1-3/4 inch. All three sit at the same Grade 1 heavy duty commercial level as the TownSteel MRX-A-72 and take the same 1-3/4 inch door, so a facility mixing secured and dummy openings can stay on one door thickness. The MRX-A-72 is non-keyed, so none of those functions are available from it.

Yes, if the door is not mortise prepped. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with a rose, for 1-3/4 inch doors, which bores instead of taking a mortise pocket. The TownSteel MRX-A-72 is a mortise type lock with a 1-1/4 inch by 8 inch stainless steel face plate and a 1-1/4 inch by 4-7/8 inch ASA strike, so it needs the full mortise prep and ASA strike cutout. On a back of house closet with no ligature concern, the cylindrical passage lock is far less prep.

Only on a very different opening. The Falcon MESC600DT is a dummy escutcheon lever trim built for M9900 Series exit devices and is fire rated; it is trim for a device, not a mortise lock body assembly. The TownSteel MRX-A-72 is a mortise type set with its own 1-1/4 inch by 8 inch stainless steel face plate and arch trim on both faces. If the door already carries an exit device, the MESC600DT is the dummy trim for it; if the door is mortise prepped with no device, the MRX-A-72 is what fits.

Those are the ones built for it. The Hager 3810S passage mortise lock covers 1-3/4 inch to 2-1/2 inch doors with a rose and 2-3/4 inch backset, and the 3810E is the same function with an escutcheon. Baldwin 6301 in entrance/apartment function lists 1-3/4 inch and over with a 2-1/2 inch backset. The TownSteel MRX-A-72 is specified at 1-3/4 inch, so on a heavier leaf the Hager or Baldwin bodies are the ones dimensioned for it, with the tradeoff that neither carries the ligature-resistant arch trim.

Satin stainless steel, BHMA 630, with a standard cylinder configuration. That is the only build, so every MRX-A opening in a facility matches without a finish decision on the order form. 630 is also the finish most behavioral health and institutional specs call for, since stainless holds up to repeated cleaning and does not show wear the way a plated brass finish does.

The Cal-Royal NM8440 is a Grade 1 privacy/bed/bath mortise lockset with deadbolt for 1-3/4 inch doors, matching the 1-3/4 inch thickness and Grade 1 level of the TownSteel MRX-A-72. Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 inch to 2 inch doors. Both give occupant-side locking, which the MRX-A-72 does not; the MRX-A-72 instead gives the ligature-resistant arch trim and tamper-resistant mounting screws that a privacy set in a patient area may not be permitted to have.

No, a lock body is half the assembly. 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 bodies that still need trim selected and ordered. The TownSteel MRX-A-72 ships as a set with the arch trim on both faces, a 1-1/4 inch by 8 inch stainless steel face plate, and a cylinder included. A buyer replacing only a failed body on an existing opening wants the BEST body; a buyer outfitting a bare door wants the complete set.
