Marks USA 5SS19WW LifeSaver Anti-Ligature Institutional Lever Mortise Lock - Storeroom, ADA Compliant

The Marks USA 5SS19WW LifeSaver is a ligature-resistant institutional lever mortise lockset engineered for demanding commercial and healthcare environments where safety and security are paramount.

Finished in polished stainless steel and featuring the SS19 lever style with rose trim, this non-handed unit meets BHMA and CULUS LISTED standards and is ADA compliant.

Marks USA 5SS19-WW-32D – Frequently Asked Questions

1) What does the F75 storeroom function on the Marks 5SS19WW actually do day to day?
Outside lever stays locked at all times and takes a key to get in; the inside lever always retracts the latch, so anyone inside gets out freely. That is ANSI F75. The catalog states the function plainly as latch retracted by knobs or levers at all times from the inside. It suits storerooms, med rooms, mechanical spaces and any institutional door that must never be left unlocked by accident.
2) Is the Marks 5SS19WW anti-ligature lock suitable for a behavioral health unit?
That is its intended use. The LifeSaver lever and trim are built ligature-resistant so clothing or a cord will not hold on the lever, and the same lock is used in correctional, detention, hospital and school settings. It pairs that with Grade 1 heavy duty construction and a clutch lever on needle bearings, so a lever that gets yanked on spins rather than breaking the spindle.
3) Does the Marks USA 5SS19WW meet ADA and fire door requirements?
ADA compliant, with a lever that operates without grasping or twisting. It is also BHMA certified, CULUS Listed and fire rated per the manufacturer's listing, and it is rated Grade 1 under ANSI/BHMA. For a healthcare or school specifier, those are the four boxes that usually have to be checked on an institutional opening.
4) Will the Marks 5SS19WW latch into my existing frame strike, or does it come with one?
A curved lip strike with a 4-7/8 inch height ships with the lock, which is the common ANSI frame prep on commercial hollow metal. The latch is deadlocking with a 9/16 inch throw, so it needs a strike lip that presses the deadlatch plunger against the frame face, not a wide-open cutout. If your frames are already prepped 4-7/8 inch ANSI, the supplied strike drops in.
5) What is the closest Grade 1 storeroom-function lever lock to the Marks USA 5SS19WW if anti-ligature trim is not required?
The Marks USA 5SS19WW LifeSaver is a Grade 1, ANSI F75 storeroom lever with a 2-3/4 inch backset, where the latch is retracted by levers at all times from the inside and the outside lever stays locked. If the opening does not need ligature-resistant trim, the Schlage NDEB is a Grade 1 heavy duty cylindrical lock offered in storeroom, office, privacy and apartment functions, fitting doors 1-5/8 to 2 inches thick, with ENGAGE wireless Bluetooth credential control rather than mechanical key-only operation. The 5SS19WW remains the choice where a behavioral health or correctional opening calls for ligature-resistant lever and rose trim.
6) I need a Grade 1 lever on a patient bathroom door, not a storeroom lock - what takes the place of the 5SS19WW there?
The Marks USA 5SS19WW is storeroom function, so it will not give a privacy indication or inside locking. For a privacy opening, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lockset fitting 1-3/8 to 2 inch doors, and the Schlage CO-100-CY-40-KP is a Grade 1 heavy duty standalone electronic cylindrical lock in privacy function for 1-3/4 inch doors. Neither carries the ligature-resistant lever and rose construction of the 5SS19WW LifeSaver, so on a behavioral health opening confirm the trim requirement first.
7) My door is 2 inches thick - the Marks USA 5SS19WW is specified for 1-3/4 inch. What else fits?
The Marks USA 5SS19WW is built for a 1-3/4 inch door thickness. For a 2 inch door, the Cal-Royal CAL20 privacy and CAL30 passage locksets cover 1-3/8 to 2 inches, the Dorma C853 entrance lever covers 1-3/8 to 2-1/4 inches, and the SDC 7200 solenoid controlled cylindrical lock covers 1-3/4 to 2 inches. Match the function you need before the thickness, since these differ from the 5SS19WW storeroom operation.
8) Do I have to specify handing when I order the Marks USA 5SS19WW LifeSaver?
No handing to call out. The 5SS19WW is non-handed, so one part number covers left and right hand openings, in-swing or out-swing. For a facility standardizing across dozens of doors that means a single stocked item instead of a split inventory.
9) What keyway does the Marks 5SS19WW come on and how many keys ship with it?
It ships with two keys cut on the Marks C keyway. If your building is already keyed on a different system, plan on a cylinder change or a rekey to bring it into the existing masterkey plan before the doors go live.
10) I need a Grade 1 lever for a storeroom door but not an anti-ligature one. What else is there?
If ligature resistance is not a requirement, the Marks 5SS19WW is more lock than the opening needs. The Dorma C853 is a Grade 1 keyed entrance lever covering 1-3/8 to 2-1/4 inch doors, and the Dorma C150 is a Grade 1 entry/office lever over the same thickness range, both with a wider door range than the 5SS19WW's single 1-3/4 inch. Where the door only needs to stay unlocked, the Cal-Royal CAL30 is a Grade 1 passage lever for 1-3/8 to 2 inch doors.
11) If I want keypad or credential access on the same institutional opening instead of the key-operated Marks USA 5SS19WW, what are the options?
The Marks USA 5SS19WW is a mechanical lockset keyed on the Marks C keyway. If the facility wants code or credential access on a 1-3/4 inch door, the TownSteel XCE-2000 is a Grade 1 heavy duty classroom electronic keypad lockset for 1-3/4 to 2 inch doors, the Schlage XE360M is a Grade 1 wireless tubular lock in classroom/storeroom function for 1-3/4 inch doors, and the SDC E75 is a battery-powered electronic cylindrical lockset with keypad for 1-3/4 to 2-1/8 inch doors. None of these are described with the ligature-resistant trim of the LifeSaver line.
12) Can I use a Dorma C150 in place of the Marks USA 5SS19WW on an office door in the same building?
Yes, for a standard office opening. The Dorma C150 is a Grade 1 heavy duty cylindrical lock in entry/office function covering doors 1-3/8 to 2-1/4 inches. The Marks USA 5SS19WW is Grade 1 storeroom function, ANSI F75, fixed to a 2-3/4 inch backset and 1-3/4 inch door. Office function allows the outside lever to be unlocked and left free; storeroom keeps it locked at all times. Keep the 5SS19WW where the anti-ligature trim is part of the spec.
13) Is the Stanley QCL150 entry lever equivalent to the Marks USA 5SS19WW?
They share a 2-3/4 inch backset, but they are not equivalent. The Stanley QCL150 is a Grade 2 entrance lever, Sierra bent lever with rose, supplied less cylinder with an ASA 4-7/8 by 1-1/4 inch strike. The Marks USA 5SS19WW is Grade 1 storeroom function, ADA compliant, and ships with two keys on the Marks C keyway plus a curved lip strike. On an institutional opening the Grade 1 rating and anti-ligature trim of the 5SS19WW are the differentiators.
14) What finish does the Marks USA 5SS19WW institutional lever come in?
One finish only: US32D satin stainless steel, with the SS19 lever style on rose trim. Stainless holds up to the wipe-down cleaning chemicals used in healthcare and detention corridors better than a plated brass finish would.
