Marks USA 5SS19GL LifeSaver Anti-Ligature Institution Privacy Lever Mortise Lock in Satin Stainless Steel

The Marks USA 5SS19GL is part of the LifeSaver series of ANSI Grade 1 institutional life safety locksets, purpose-engineered to address managed liability, accident prevention, life safety, and security in behavioral health care institutions, X-ray settings, and correctional facilities. This anti-ligature mortise lockset features a Privacy (ANSI F26) function with a thumb turn on the inside and coin turn on the outside, and is designed to restrict the attachment of lines, laces, and similar items to door levers. Built entirely from stainless steel with a Satin Stainless Steel finish, it accommodates a 1 3/4" door thickness with a 2 3/4" backset and a steel case measuring 4 3/16" x 6 1/16" x 7/16". The 5SS19GL is non-handed, ADA compliant, fire rated, and backed by the Marks USA Lifetime Mechanical Warranty.

Marks USA 5SS19GL-32D – Frequently Asked Questions

1) Will the Marks USA 5SS19GL LifeSaver anti-ligature lock fit a 1-3/4 inch door with a 2-3/4 inch backset?
That is exactly the prep it is built for. The Marks USA 5SS19GL LifeSaver is specified for a 1-3/4 inch door thickness with a 2-3/4 inch backset, which is the standard commercial backset on a 1-3/4 inch door. The lock front measures 1-1/8 by 2-1/4 inches. If your openings are thinner than 1-3/4 inches, or you have a mix of thicknesses across a floor, this is not the right part for those doors.
2) What makes the Marks USA LifeSaver 5SS19GL an anti-ligature lock for a behavioral health unit?
The lever geometry is the point. The 5SS19GL LifeSaver is engineered to restrict the attachment of lines, laces and similar items to the lever, so a patient cannot anchor a ligature to the hardware. It is intended for behavioral health care institutions, psychiatric and mental health facilities, correctional facilities, X-ray and imaging rooms, and secure residential treatment settings. Ordinary lever trim on the same door prep does not do this, no matter what grade it carries.
3) Do I have to order the Marks USA 5SS19GL handed left or right?
No handing to specify. The 5SS19GL LifeSaver is non-handed, so one part number covers left and right hand openings, and it retrofits popular door preps and door constructions. For a facility standardizing one SKU across a whole wing, that removes the usual count of lefts versus rights before the order goes in.
4) Does the Marks USA 5SS19GL need a key or a cylinder ordered with it?
No cylinder and no keying. The 5SS19GL LifeSaver is a non-keyed lockset, operated by a thumb turn on the inside and a coin turn on the outside, so staff can release it from the corridor side with a coin or a flat tool instead of a key. Nothing else has to be added to the order to make it function.
5) Is the Marks USA 5SS19GL LifeSaver ANSI Grade 1, UL listed and ADA compliant?
All three. The 5SS19GL LifeSaver is ANSI Grade 1, ANSI/BHMA certified and UL Listed, and it is ADA compliant. It is classified as commercial hardware, which is the specification level an institutional or government facility usually has to hit on a life safety opening.
6) What is a simpler mechanical privacy lockset than the Marks USA 5SS19GL for a restroom that does not need ligature resistance?
The Cal-Royal CAL20 covers that opening. It is a Grade 1 extra heavy duty privacy lock in the Calypso series with a 1-3/8 to 2 inch door thickness range, so it fits a wider run of doors than the 5SS19GL, which is built for a 1-3/4 inch door. Both are mechanical and non-keyed in the privacy sense. What the CAL20 does not carry is the LifeSaver anti-ligature lever geometry or the all stainless steel construction the 5SS19GL uses in behavioral health and correctional work. For a standard commercial restroom or office bed/bath opening, the CAL20 is the straightforward choice; for a psychiatric or secure residential door, it is not a substitute.
7) What is the closest equivalent to the Marks USA 5SS19GL for a privacy opening on a 1-3/4 inch door?
For a privacy function on a 1-3/4 inch door, the Schlage CO-100-CY-40-KP is the nearest peer: it is a Grade 1 heavy duty cylindrical lock with a Privacy/Bed/Bath function and a 1-3/4 inch door thickness. The difference is how it locks. The 5SS19GL is a mechanical lock with no key involved, using a thumb turn inside and a coin turn outside, while the CO-100 is a standalone electronic lock operated by keypad with cylinder options. The 5SS19GL is also anti-ligature and built entirely of stainless steel for behavioral health, correctional, and X-ray settings; the CO-100 is a general-purpose commercial privacy lock. If the opening is a patient room or a cell where ligature resistance is the whole point, the CO-100 does not substitute.
8) Can an electronic privacy lock like the Alarm Lock Trilogy 4100 be used in place of the Marks USA 5SS19GL?
Only where ligature resistance is not a requirement. The Alarm Lock Trilogy 4100 is a Grade 1 electronic cylindrical lock with a Privacy/Bed/Bath function and a keypad, fitting a 1-5/8 to 1-7/8 inch door. That door range covers the 1-3/4 inch door the 5SS19GL is built for, and the function matches on paper. The separation is the lever and the credential. The 5SS19GL uses a clutch lever shaped to restrict the attachment of lines and laces, operates with no key or code at all, and is all stainless steel; the Trilogy 4100 is a battery keypad lock with programmable access. Behavioral health, correctional, and secure treatment openings are written around the anti-ligature lever, so the 4100 is a substitute for a staff office or a general privacy door, not for a patient room.
9) Will the 9/16 inch latch on the Marks USA 5SS19GL work with my existing strike?
The 5SS19GL LifeSaver throws a 9/16 inch deadlocking latch, which is the common commercial latch projection, so it lands in a standard frame strike pocket cut for a 2-3/4 inch backset lockset. The deadlocking feature means the latch is blocked against being carded or shimmed once the door is closed. Check that your existing strike lip and pocket were cut for a lockset latch and not a deadbolt before reusing the frame prep.
10) What finish does the Marks USA 5SS19GL LifeSaver come in, and will it hold up to washdown and disinfectant?
One finish: US32D satin stainless steel. The LifeSaver locks are built entirely of stainless steel rather than plated brass or steel, so the corrosion resistance is in the base material and repeated cleaning or disinfecting will not strip a plating off it. The LifeSaver line also includes antimicrobial finish options for hygiene sensitive areas.
11) Is there an electronic or credential-based alternative to the Marks USA LifeSaver for institutional doors?
Several, if access control matters more than ligature resistance. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic lock with a privacy function for 1-3/4 inch doors, and the Alarm Lock Trilogy 4100 is a Grade 1 electronic privacy lock for 1-5/8 to 1-7/8 inch doors. Neither is anti-ligature. On a behavioral health opening the 5SS19GL LifeSaver is the one doing that job; the electronic units suit staff and administrative doors in the same building.
12) If the opening needs a passage function instead of privacy, what replaces the Marks USA 5SS19GL?
The Cal-Royal CAL30 is the passage counterpart: a Grade 1 extra heavy duty Passage/Hall/Closet cylindrical lockset with a 1-3/8 to 2 inch door thickness range. For a medium duty passage opening, the Orca Hardware OCL210 is a Grade 2 passage cylindrical lockset. The 5SS19GL differs in that its latch is retracted by the levers at all times but it adds inside locking through a thumb turn with a coin turn release outside, which a true passage lockset does not have. Specify the passage lockset where the door should never latch against anyone, and the 5SS19GL where an occupant needs to secure the room and staff need to release it from the corridor.
13) What should a facility use instead of the Marks USA 5SS19GL on a door that needs keyed entry?
The 5SS19GL is not keyed, so a keyed opening needs a different lockset. The Dorma C853 is a Grade 1 entrance lever lockset, keyed single cylinder, for a 1-3/8 to 2-1/4 inch door. The Dorma C150 is a Grade 1 heavy duty cylindrical lock with an entry/office function over the same 1-3/8 to 2-1/4 inch range. For a Grade 2 medium duty entrance, the Orca OCL250 is the keyed option. None of those carry the LifeSaver anti-ligature lever, so on a secure ward the usual split is the 5SS19GL on the patient-side privacy doors and a keyed entrance lockset on the staff and corridor doors.
14) Is the Orca Hardware OCL240 privacy lockset an equivalent to the Marks USA 5SS19GL?
They share the privacy function but not the duty rating. The Orca OCL240 is a Grade 2 medium duty privacy cylindrical lockset. The 5SS19GL is Grade 1 and ANSI/BHMA certified and UL listed. On an institutional opening written to a Grade 1 line item, the OCL240 will not meet the spec on the drawing. The OCL240 suits lighter traffic privacy doors where a Grade 2 medium duty lockset is acceptable.
15) Does the Marks USA 5SS19GL fit doors outside 1-3/4 inch, and what covers a thicker or thinner door?
The 5SS19GL is built for a 1-3/4 inch door with a 2-3/4 inch backset. For openings that vary across a building, the Dorma C150 and Dorma C853 both span 1-3/8 to 2-1/4 inch doors in Grade 1, and the Cal-Royal CAL20 privacy and CAL30 passage cover 1-3/8 to 2 inch. The SDC E75 electronic cylindrical lockset runs 1-3/4 to 2-1/8 inch. None of those carry the anti-ligature lever, so where the door is off 1-3/4 inch and ligature resistance is still required, the door itself is the item to confirm before selecting trim.
16) Will the Marks USA 5SS19GL hold up to constant use on a patient room door?
It is built for that traffic. The 5SS19GL LifeSaver uses a clutch lever running on needle bearings, so force applied to a locked lever turns the lever rather than loading the internal mechanism, and the whole lockset is Grade 1 stainless. That combination is what lets it take the abuse a behavioral health or correctional door sees without the trim going loose.
17) For a classroom or intruder-function opening in the same institutional building as the Marks USA 5SS19GL, what lockset covers it?
The 5SS19GL is a privacy lockset with a thumb turn and coin turn and does not offer a classroom function. For classroom openings on a 1-3/4 inch door, the TownSteel FCE-2000 is a Grade 1 heavy duty standalone motorized cylindrical lockset with RFID and a classroom function, and the FCE-4000 is the RFID electronic intruder classroom version on the same door thickness. The TownSteel XCE-9000 is a Grade 1 heavy duty electronic classroom intruder lockset with a keypad for 1-3/4 to 2 inch doors. Schools and secure treatment centers commonly run a classroom intruder lock on the corridor doors and a privacy lock like the 5SS19GL on the toilet and resident room doors.
18) What is the difference between the Marks USA 5SS19GL and a keypad lock like the Alarm Lock DL2700 for an institutional door?
They solve different problems. The Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical entrance lock with a digital keypad, 100 user codes, and IC/SFIC compatibility, fitting a 1-5/8 to 1-7/8 inch door. It manages who gets in and is keyed through an interchangeable core. The 5SS19GL is not keyed at all: it is a privacy lock whose latch is retracted by the levers at all times, with inside thumb turn locking and outside coin turn release, and it is ANSI/BHMA certified and UL listed. A ward that needs credentialed access on the corridor and ligature-resistant privacy on the resident rooms uses both, on different doors.
