The Marks USA 5SS19EW LifeSaver is an institutional-grade anti-ligature storeroom lever mortise lock engineered for demanding environments including healthcare facilities, schools, and other institutional settings.

The SS19 lever style with rose trim provides a ligature-resistant profile, while the storeroom function (ANSI F07) keeps the latch retracted by levers at all times with outside access via keyway. UL Listed for 3-hour fire rating and fully ADA compliant, this lock meets BHMA and CULUS standards for high-traffic commercial applications.

Marks USA 5SS19EW-32D – Frequently Asked Questions

1) What does the storeroom function mean on this Marks USA LifeSaver lock day to day?
Outside lever stays locked at all times and takes a key to get in. The inside always retracts the latch for free egress, so nobody can be trapped in the room. That is ANSI F07 storeroom behavior. It is the right choice for janitor closets, med rooms, mechanical spaces and behavioral health storage where the door must never be left unlocked by accident, because there is no way to hold it in an unlocked state.
2) Is this Marks USA lock actually anti-ligature, and where is it used?
The SS19 lever and rose trim are shaped to be ligature resistant, which is why the LifeSaver name is on it. The sloped profile gives a cord or strap nothing to hold onto. Typical openings are behavioral health and psychiatric units, hospitals, correctional and detention facilities, schools, and assisted living. If you are specifying for a patient room or a seclusion area, this is the lever family to be looking at.
3) Can I put the Marks 5SS19EW on a fire rated door?
Yes. The 5SS19EW is UL Listed for a 3 hour fire rating and is CULUS Listed, which covers stair doors, corridor doors and cross-corridor openings in healthcare and institutional buildings. The latch is deadlocking, which is what a fire assembly needs so the door stays positively latched under pressure.
4) Will this Marks USA lock latch into the strike that is already in my frame?
It throws 9/16 inch and ships against an ASA curved lip strike with a 4-7/8 inch plate height. If your frame already has a standard 4-7/8 inch ASA strike prep, which most commercial hollow metal frames do, the existing cutout will take it. A frame prepped for a T-strike or a small 2-3/4 inch residential strike will need the jamb reworked.
5) My doors are 2 inches thick. What Grade 1 lever can I use instead of the Marks 5SS19EW?
The 5SS19EW will not work there, it is a 1-3/4 inch only lock. For a 2 inch leaf, the Cal-Royal CAL30 Grade 1 passage lever covers 1-3/8 to 2 inches, and the Dorma C853 Grade 1 keyed entry lever and Dorma C150 both run 1-3/8 to 2-1/4 inches. Pick the function that matches the opening, since the CAL30 is passage and the two Dorma units are keyed.
6) My door is 1-3/8 inch thick. Can I use the Marks 5SS19EW, and if not what fits?
The Marks 5SS19EW requires a 1-3/4 inch door thickness, maximum 1-3/4 inch, so a 1-3/8 inch leaf is out of range. The Dorma C853 C800 Series entrance lever lockset covers 1-3/8 inch to 2-1/4 inch at Grade 1, and the Dorma C150 Grade 1 entry/office lock covers the same 1-3/8 inch to 2-1/4 inch range. Both are entrance rather than storeroom function.
7) What is the closest Grade 1 storeroom-function alternative to the Marks USA 5SS19EW for a behavioral health opening?
Within the comparable set there is no other mechanical anti-ligature storeroom lever. The nearest storeroom-capable peers are electronic: the Schlage NDEB ENGAGE Series is a Grade 1 heavy duty cylindrical lock offering storeroom, office, privacy and apartment functions for doors 1-5/8 inch to 2 inch, and the Schlage XE360M is a Grade 1 wireless tubular lock with a classroom/storeroom function for 1-3/4 inch doors. Both add credential management the Marks 5SS19EW does not have; neither carries the ligature-resistant SS19 lever and rose profile that makes the Marks unit suited to behavioral health openings.
8) Does the Marks 5SS19EW meet ADA and what grade is it?
ADA compliant by way of the lever design, which needs no tight grasping or wrist twisting to operate. It is Grade 1 under ANSI/BHMA with a steel case, the heavy duty tier intended for high traffic commercial and institutional openings. That combination is what most healthcare and education specs call for on a storeroom door.
9) What are the case dimensions I need for door prep on the Marks LifeSaver mortise lock?
The steel case measures 4 3/16 x 6 1/16 x 7/16 inches, seated on a 2-3/4 inch backset with a 1-1/8 x 2-1/4 inch front. Cut the mortise pocket to those case figures and set the armor front flush. Door must be 1-3/4 inches thick.
10) What keyway does the Marks USA 5SS19EW use, and can I key it into my building master system?
Outside access is through the Marks C keyway. If your facility is already standardized on Marks C, these drop straight into that key system for master keying. If your building is on a Schlage, Best or Sargent keyway, plan on either a different cylinder arrangement or accepting a second key for these openings.
11) Can I get the Marks LifeSaver storeroom lock with a keypad or card reader instead of a key?
No. The 5SS19EW is a mechanical lock with key access on the outside, nothing electronic. If the opening needs credential access, the Grade 1 electronic cylindrical options include the Alarm Lock Trilogy T2 DL2700 with 100 user codes for 1-5/8 to 1-7/8 inch doors, the TownSteel XCE-2000 keypad lockset for 1-3/4 to 2 inch doors, and the SDC Electra 7200 solenoid controlled lock at 12/24VDC for 1-3/4 to 2 inch doors if you are tying into access control. None of those are anti-ligature, so they do not substitute on a patient room door.
12) I need a Grade 1 lever lock but the opening is a plain passage door, not a secure storeroom. What should I use instead of the Marks 5SS19EW?
For an unsecured passage opening, the Cal-Royal CAL30 Calypso Series is a Grade 1 extra heavy duty passage lockset in the passage/hall/closet function for doors 1-3/8 inch to 2 inch, which covers a wider door thickness range than the 1-3/4 inch the Marks 5SS19EW requires. The CAL30 has no key control, while the 5SS19EW retracts the latch by lever with outside access through the keyway on a Grade 1 storeroom function.
13) What is a lower-cost medium duty option if my opening does not need the Marks 5SS19EW institutional build?
The Orca Hardware OCL250 is a Grade 2 medium duty entrance cylindrical lockset, and the OCL210 is a Grade 2 medium duty passage lockset. Both are cylindrical trim for ordinary commercial doors. The Marks 5SS19EW is a Grade 1 commercial unit with a steel mortise case measuring 4 3/16 by 6 1/16 by 7/16 inch, a 2-3/4 inch backset, UL listing for a 3-hour fire rating and an anti-ligature lever profile, so it is the choice where fire rating and ligature resistance are on the spec.
14) For a school classroom door, should I spec the Marks 5SS19EW or a TownSteel classroom lockset?
The TownSteel FCE-2000 Series is a Grade 1 heavy duty standalone motorized cylindrical lockset with RFID in a classroom function for 1-3/4 inch doors, and the FCE-4000 Series is a Grade 1 heavy duty RFID electronic intruder classroom lockset, also 1-3/4 inch. Those give credentialed and lockdown control on a classroom opening. The Marks 5SS19EW is a Grade 1 mechanical storeroom lock with a UL 3-hour fire rating and an anti-ligature lever, which suits secured storage and behavioral health doors rather than classroom lockdown.
15) What is a Grade 1 privacy lever alternative for patient room doors when the Marks 5SS19EW storeroom function is wrong?
The Cal-Royal CAL20 Calypso Series is a Grade 1 extra heavy duty privacy lock in the privacy/bed/bath function for doors 1-3/8 inch to 2 inch, and the Alarm Lock Trilogy 4100 is a Grade 1 electronic privacy lock with keypad for doors 1-5/8 inch to 1-7/8 inch. The Marks 5SS19EW keeps the outside lever locked at all times with key access, which is not what a patient room privacy opening calls for.
16) Can a Lockey mechanical pushbutton lock replace the Marks 5SS19EW on a healthcare storeroom?
The Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function for doors 1-1/8 inch to 2 inch, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with adjustable backset over the same 1-1/8 inch to 2 inch range. Both are knob trim, so they will not meet the ADA lever requirement the Marks 5SS19EW satisfies, and neither carries the ligature-resistant profile needed in behavioral health areas.
17) What finish does this Marks anti-ligature lock come in?
Satin stainless steel, US32D, is the finish offered on the 5SS19EW. Stainless holds up to the cleaning chemicals and constant wipe-down that healthcare and behavioral units put hardware through, and it matches most institutional push plates and hinges already on the doors.
18) Does the Schlage CO-100 do the same job as the Marks 5SS19EW?
Not the same function. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic cylindrical lock in a privacy function with keypad and cylinder options, built for 1-3/4 inch doors. The Marks 5SS19EW is a storeroom lock: the outside lever is always locked and requires a key, with free egress inside. Use the CO-100 where you want occupant-controlled privacy and the 5SS19EW where the door must stay secured to key control.
