TownSteel MRX-A-20-630-RH – Frequently Asked Questions

1) Will the TownSteel MRX-A-20 mortise lock fit a 1-3/4 inch door?
Yes, and only 1-3/4 inches. The MRX-A-20 is built for a single door thickness of 1-3/4 inch, which is the standard commercial door. It mounts on either a wood or a metal door, so a hollow metal frame opening or a solid core wood door both work.
2) What does the -20 Entrance/Apartment/Dormitory function with T-turn actually do?
Key from outside retracts the latch, and the inside T-turn lets the occupant lock or unlock the outside trim without a key. It is the function used on apartment, dormitory and patient room doors where the person inside controls the outside trim. The lock is single cylinder, so there is no key cylinder on the inside face.
3) Is this lock suitable for a behavioral health or psychiatric patient room?
That is exactly what the MRX-A was built for. It carries a 5-point ligature-resistant stainless steel arch trim and tamper-resistant mounting screws, and TownSteel states it is suitable for behavioral, mental and psychiatric healthcare facilities housing patients at risk.
4) Do I have to specify handing when ordering the MRX-A-20?
Yes. Handing is a required choice: left hand, left hand reverse, right hand, or right hand reverse. Reverse handing means the door opens toward you (outswing) from the secure side. Stand outside the door, note the hinge side and the swing direction, and pick accordingly. All four handings come in 630 satin stainless steel.
5) Can I get the MRX-A-20 prepped for a small format interchangeable core?
Yes. Two cylinder choices are offered: a standard cylinder, which ships with the lock, or SFIC prep less core, if you are supplying your own small format interchangeable core from an existing facility system. Either way, keying is specified at order: keyed different, keyed alike for multiple locks, or a specific key code.
6) What strike and faceplate prep does the MRX-A-20 need in the frame?
The lock uses a 1-1/4 x 4-7/8 inch ASA strike, which is the common commercial mortise strike prep, and the faceplate is 1-1/4 x 8 inches in stainless steel. If your frames are already prepped for an ASA strike of that size, the cutout carries over.
7) What other ligature resistant mortise hardware works on a behavioral health door besides the TownSteel MRX-A-20?
The Marks USA 5PDN is the closest peer in intent: a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant, and finished in satin stainless steel. The difference is function. The MRX-A-20 is a keyed Entrance/Apartment/Dormitory lock with a T-turn and a single cylinder, so it secures the opening; the 5PDN is a passage paddleset with no keyed function, for doors that only need to latch. Use the MRX-A-20 where the room must lock and the 5PDN where staff need free passage.
8) If the opening does not need ligature resistant trim, what is a straight Grade 1 mortise entrance lock to use instead of the MRX-A-20?
The Cal-Royal NM8050 is a heavy duty Grade 1 Entrance/Office mortise lockset with an auxiliary deadlatch, rated for 1-3/4 inch doors, the same door thickness the MRX-A-20 is built for. The Baldwin 6301LS is another entrance/apartment mortise lock body, lever by lever with a 2-1/2 inch backset for doors 1-3/4 inch and over. Both use conventional lever trim rather than the 5-point ligature-resistant stainless arch trim and tamper-resistant mounting screws that define the MRX-A-20.
9) Is a storeroom mortise lock a substitute for the TownSteel MRX-A-20?
No - the functions differ. 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. Storeroom function keeps the outside lever locked at all times with key access only. The MRX-A-20 is Entrance/Apartment/Dormitory with a T-turn, which lets the occupant lock and unlock the outside trim from inside. Specify storeroom only if the door should never be left unlocked by the occupant.
10) Is the MRX-A-20 Grade 1, and is it heavy duty enough for a high traffic facility?
It is an ANSI Grade 1 mortise lock rated heavy duty for commercial use. Grade 1 is the highest ANSI/BHMA performance tier and the level usually specified for healthcare, institutional and multi-family corridor doors.
11) What is the difference between the MRX-A arch trim and a normal lever mortise lock?
The arch trim has no projecting lever to tie a cord or strap to, which is why it is used in patient rooms. A conventional lever mortise lock like the Cal-Royal NM8050 Grade 1 entrance/office lockset or the Corbin Russwin ML2003 Grade 1 classroom lock is the right pick for offices, classrooms and back of house, where ligature resistance is not a concern and a lever is easier to operate.
12) Can I use an electronic mortise lock in place of the TownSteel MRX-A-20 for credential access?
Yes, if the opening does not require ligature-resistant trim. The Schlage CO-100 is a Grade 1 standalone electronic mortise lock with a keypad reader for 1-3/4 inch doors, and the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes. The MRX-A-20 is a mechanical lock with no electronics, keyed single cylinder with a T-turn, so swapping to either of those adds credential management but gives up the 5-point ligature-resistant stainless arch trim and tamper-resistant screws.
13) I need a dormitory function mortise lock but with rose trim instead of arch trim - what is the alternative to the MRX-A-20?
The Sargent 7925 is a Grade 1 heavy duty Corridor/Dormitory function mortise lock with rose trim and a single cylinder deadbolt. The MRX-A-20 covers the Entrance/Apartment/Dormitory function with a T-turn on the inside and a 5-point stainless arch trim, so the two serve similar occupancies with different trim and different inside operation - deadbolt on the Sargent, T-turn on the TownSteel.
14) What should I specify instead of the MRX-A-20 for a classroom door in the same facility?
For classroom function, 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 with an auxiliary deadlatch, also 1-3/4 inch. Both match the MRX-A-20 at Grade 1 and 1-3/4 inch door thickness, but neither carries the ligature-resistant arch trim, so keep the MRX-A-20 on patient-accessible openings.
15) What is the difference between the MRX-A-20 and a BEST 45H mortise lock body?
The BEST 45HCAC is a heavy duty Public Entrance function mortise lock body with field reversible operation, and the 45HCAINL is a heavy duty Intruder function lockbody in the same family - both are lock bodies, supplied to be paired with separately specified trim. The MRX-A-20 ships as a complete lockset: Grade 1 heavy duty mortise lock with the 5-point ligature-resistant stainless arch trim, a cylinder, and a 1-1/4 by 8 inch stainless face plate, ordered by handing in LH, LHR, RH or RHR.
16) For a patient bathroom that needs privacy rather than keyed entry, what do I order instead of the MRX-A-20?
The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a 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. Both give Privacy/Bed/Bath function with no outside key cylinder, where the MRX-A-20 is a single cylinder keyed Entrance/Apartment/Dormitory lock. Note that neither privacy peer carries ligature-resistant trim, so confirm the room's risk level before substituting.
17) What finish does the TownSteel MRX-A-20 come in?
One finish only: 630 satin stainless steel, across all four handings and both cylinder options. That is the standard institutional finish, so it will sit alongside stainless push plates, hinges and other 630 hardware already in a healthcare corridor.
18) We only need the door to latch, no locking - is there a simpler mortise lock than the MRX-A-20?
Yes. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset. All three are passage only with no cylinder, where the MRX-A-20 is a single cylinder keyed lockset that includes a cylinder.
19) Does a Sargent 130KB thumbturn replace the T-turn on the MRX-A-20?
No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 series, and the 130W is a mortise thumbturn with a round backplate in the 7800 series - both are trim components for those Sargent mortise bodies. The MRX-A-20 is a complete Grade 1 heavy duty mortise lockset whose T-turn is part of the 5-point ligature-resistant stainless arch trim, so it is not fitted with an aftermarket thumbturn.
