TownSteel MRX-A-35-630-RH – Frequently Asked Questions

1) Will the TownSteel MRX-A-35 mortise lock fit a 1-3/4 inch door?
Yes, and that is the only thickness it is built for. The MRX-A-35 is specified for 1-3/4 inch doors, which is the standard commercial door thickness. It mounts on either a wood or a metal door. If your openings are thicker or thinner, this is the wrong lock for them.
2) What does the storeroom function with deadbolt actually do on the MRX-A-35?
The outside arch trim stays locked at all times and is retracted by key only; the inside trim always retracts the latch for free egress. On top of that latch, the -35 carries a deadbolt, and it is a double cylinder arrangement, so the bolt is thrown and withdrawn by key from either side. That combination is common on psychiatric and behavioral healthcare rooms where staff control access but the door must still open from inside.
3) Do I have to specify handing when ordering the MRX-A-35 ligature resistant mortise lock?
Yes. Handing is a required selection: left hand, left hand reverse, right hand, and right hand reverse are all offered. Stand outside the opening, note which side the hinges are on and which way the door swings, and pick accordingly. Reverse designations mean the door swings toward you.
4) Can I get the MRX-A-35 prepped for small format interchangeable core so it goes on our existing key system?
Yes. Two cylinder builds are offered: a standard cylinder, which ships with the lock, or SFIC prep less core, so your locksmith drops in your own small format core and the opening joins your existing master key system. Keying is also a required choice at order time: keyed different, keyed alike for a group of locks, or a specific key code you supply.
5) What strike and face plate prep does the MRX-A mortise lock need in the frame?
It uses a 1-1/4 by 4-7/8 inch ASA strike, which is the standard commercial mortise strike cutout, so it drops into a frame already prepped for an ASA strike. The lock face plate is stainless steel at 1-1/4 by 8 inches.
6) What makes this lock ligature resistant, and is that just the lever shape?
The MRX-A uses a 5-point ligature-resistant stainless steel arch trim rather than a lever, so there is no projection a cord or sheet can be tied around. It is also fitted with tamper-resistant mounting screws so the trim cannot be removed with common tools. That is what separates it from a standard Grade 1 storeroom mortise lock with a lever.
7) Is there another ligature-resistant option for a behavioral health door instead of the MRX-A-35 lockset?
Yes. The MRX-A-35 is a keyed storeroom mortise lock with a deadbolt and a 5-point ligature-resistant stainless steel arch trim. For an opening that needs ligature resistance but no locking, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset described as ligature resistant and ADA compliant in satin stainless steel. Use the MRX-A-35 where the door must be secured by key and the 5PDN where free passage is wanted.
8) What is a comparable Grade 1 storeroom mortise lock if ligature resistance is not required?
The TownSteel MRX-A-35 is a Grade 1 storeroom mortise lock carrying a ligature-resistant arch trim, which is what makes it appropriate for behavioral and psychiatric patient areas. On a standard commercial opening where ligature resistance is not part of the spec, the Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. Both use conventional lever trim rather than a 5-point arch trim.
9) Is the MRX-A-35 heavy duty enough for a hospital corridor?
It is an ANSI Grade 1 mortise lock rated heavy duty and catalogued for commercial use. Grade 1 is the highest ANSI/BHMA durability tier and the usual specification for healthcare, institutional and high traffic openings.
10) Does the MRX-A-35 come with a cylinder or do I have to buy one separately?
A cylinder is included when you choose the standard cylinder build. If you order the SFIC prep version, it ships less core and you supply the small format interchangeable core yourself. Since this is a double cylinder deadbolt arrangement, plan on key control from both sides of the opening.
11) I need a classroom function mortise lock instead of storeroom for a patient area corridor. What are the options?
The MRX-A-35 is built as a storeroom function with a dead bolt, so it will not give you classroom operation. For classroom function in a Grade 1 mortise, the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 series, also 1-3/4 inch. Neither carries the arch ligature-resistant trim of the MRX-A-35.
12) Can I use an electronic mortise lock in place of the MRX-A-35 on a behavioral health room?
The MRX-A-35 is a mechanical lock with no electronic component, keyed as a double cylinder storeroom set with a deadbolt. Electronic mortise alternatives include the Alarm Lock DL3500CR, a Grade 1 Trilogy electronic mortise lock with classroom function and 300 user codes for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100-MS, a Grade 1 standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors. Those carry keypad hardware and levers rather than a ligature-resistant arch trim, so confirm they suit a patient-at-risk opening before substituting.
13) Will a Sargent 4874 mortise deadbolt do the same job as the MRX-A-35?
No. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset and nothing more - it has no latch and no trim. The TownSteel MRX-A-35 is a complete storeroom lockset that combines a latch with a dead bolt and includes the ligature-resistant arch trim and a cylinder. Order the 4874 only as an auxiliary deadbolt above a separate latching device, not as a replacement lockset.
14) I only need the mortise lock body, not a full trimmed set. What should I order instead of the MRX-A-35?
The MRX-A-35 ships as a complete set with its ligature-resistant arch trim and cylinder. If the opening already has acceptable trim and you only need a heavy duty lock body, the BEST 45H series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the Baldwin 6310 is an entry/storeroom mortise lock body with a 2-1/2 inch backset for doors 1-3/8 inch and over. Verify backset and faceplate prep against the existing door - the MRX-A-35 uses a 1-1/4 by 8 inch stainless faceplate and a 1-1/4 by 4-7/8 inch ASA strike.
15) What should I use for a dormitory or privacy opening where the MRX-A-35 storeroom function is wrong?
For a dormitory-style door, the Sargent 7925 is a Grade 1 heavy duty corridor/dormitory function mortise lock with rose trim and a single cylinder deadbolt. For bed/bath privacy, the Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with 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. The MRX-A-35 remains the choice where the door must stay locked to the outside at all times with a keyed double cylinder.
16) Does the door thickness limit of the MRX-A-35 rule it out where Alarm Lock mortise locks would fit?
The TownSteel MRX-A-35 is specified for 1-3/4 inch doors. The Alarm Lock DL2700CR and DL3500CR Trilogy electronic mortise locks cover 1-5/8 to 1-7/8 inch, and the DL4500 electronic mortise deadbolt covers the same 1-5/8 to 1-7/8 inch range, so those suit a door slightly under or over 1-3/4 inch. Measure the leaf before ordering.
17) What finish does the TownSteel MRX-A-35 come in, and will it match other stainless hardware?
One finish: 630, satin stainless steel, across every handing and cylinder build. That is the standard institutional finish, so it lines up with satin stainless push plates, hinges and exit hardware already on most healthcare openings.
18) Is the TownSteel MRX-A-35 an electronic or access control lock?
No, it is purely mechanical, key operated. If you need credential or keypad control on a mortise prep, look at electronic mortise locks such as the Schlage CO-100 standalone keypad mortise lock or the Dormakaba E-Plex 2066 pushbutton keyless mortise lock instead. Those will not give you ligature-resistant arch trim.
19) Is the Schlage PM010 an acceptable substitute for the MRX-A-35?
Only if the door does not need to lock. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, so it latches but never secures. The TownSteel MRX-A-35 is a keyed double cylinder storeroom set with a dead bolt. For a passage opening in the same facility, the Falcon MA101 is another Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating.
