Marks USA 5SS19N-32D – Frequently Asked Questions

1) Can I key the Marks 5SS19N LifeSaver, or lock the door with it?
No. It's ANSI F75 passage, which means no cylinder and no locking at all, either side. If you need a patient room or restroom to lock, this is the wrong function. For a privacy function in the same institutional class, the Cal-Royal CAL20 is a Grade 1 privacy lever; for entry, the Dorma C853 is a Grade 1 keyed-entry lever. Neither of those is ligature-resistant, though, so on a behavioral health opening you want the locking version within the Marks LifeSaver line rather than a standard lever.
2) What does the anti-ligature design on the Marks 5SS19N actually do, and where is it used?
The SS19 lever and rose are shaped so a cord or sheet can't be looped and held on the hardware, which is why it goes on behavioral health, psychiatric, detention and correctional openings. It's a passage function, so the latch pulls back from either lever at all times with no key and no way for an occupant to lock themselves in. Nothing in the comparable set of standard cylindrical levers is ligature-resistant, so this is not a spec you can match by picking another Grade 1 passage lock.
3) Will the 5SS19N latch work with the strike already in my frame?
Check two numbers. The 5SS19N throws its latch 9/16 in and ships with a 4-7/8 in curved lip strike, with a 1-1/8 in x 2-1/4 in front. If your frame is prepped for a standard 4-7/8 in ANSI strike you're fine; if it's an older wrap-around or a T-strike prep, plan on reworking the frame. The latch is deadlocking, so the strike has to seat it fully for the deadlocking feature to do its job.
4) Is the Marks 5SS19N handed? Do I need to specify left or right?
Non-handed. You order one part number and it works on either swing, which is the point on a multi-door institutional job where you're stocking spares for a whole wing. Backset is fixed at 2-3/4 in, so the door bore has to be on the 2-3/4 in centerline, not the 2-3/8 in residential one.
5) Is this lock rated for a fire door?
Yes. The 5SS19N is cULus Listed and UL Listed for a 3-hour fire rating, so it can go on a 3-hour rated opening. It's also ANSI/BHMA Grade 1 and ADA compliant, which together cover the usual spec-book line items on a corridor or stair door in a healthcare or government building.
6) What is the closest Grade 1 passage lever alternative to the Marks USA 5SS19N for a standard corridor door that does not need ligature resistance?
The Cal-Royal CAL30 Calypso is a Grade 1 passage/hall/closet cylindrical lockset and is the nearest straight equivalent by grade and function. The Marks USA 5SS19N is also Grade 1 with a Passage/Hall/Closet function, but its SS19 lever and rose are built ligature-resistant for behavioral health and detention openings. The CAL30 covers a 1-3/8 in to 2 in door thickness range, while the 5SS19N is built for a 1-3/4 in door. Pick the 5SS19N where the opening is in a patient or detention area and the CAL30 where it is a conventional commercial corridor.
7) Is the Orca OCL210 passage lockset a drop-in substitute for the Marks USA 5SS19N?
No. The Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset, while the Marks USA 5SS19N is Grade 1 and built as an anti-ligature institutional lockset for behavioral health and detention environments. Both carry a Passage/Hall/Closet function, so the OCL210 will operate the same way at the lever, but it does not carry the Grade 1 certification or the ligature-resistant lever and rose that a psychiatric or correctional specification calls for. Use the OCL210 on back-of-house or light-traffic openings and the 5SS19N where the drawing calls for Grade 1 anti-ligature hardware.
8) How does the 5SS19N hold up in a high-abuse corridor compared with a standard Grade 1 passage lever?
It's built around a clutch lever and needle bearings on a stamped steel case, so force applied to the lever turns it free rather than driving the spindle and internals. That's the difference that matters where residents hang on levers. A Grade 1 passage lever like the Cal-Royal CAL30 meets the same grade but is a conventional lever; the Orca OCL210 passage lockset is Grade 2 medium duty, which is a step down for this kind of traffic.
9) I need access control on a behavioral health door. Can I use the 5SS19N?
No. The 5SS19N is a mechanical passage lock with no cylinder and no electrified option. For a credentialed opening on a 1-3/4 in door, the TownSteel FCE-2000 is a Grade 1 standalone motorized RFID cylindrical lockset and the Schlage XE360M is a Grade 1 wireless tubular lock with a mobile reader, both rated at 1-3/4 in thickness. Neither is ligature-resistant, so on a patient-side opening you'd typically keep the LifeSaver hardware and put the access control on the corridor or staff door instead.
10) Can I standardize the 5SS19N across a whole floor of doors?
It's a good candidate for it. One part number covers both swings, the finish is a single satin stainless, and the door prep is the same everywhere: 2-3/4 in backset, 1-3/4 in door, 4-7/8 in strike, 1-1/8 in x 2-1/4 in front. Where a door needs to lock you'll break out of this part number, since F75 passage doesn't lock, so plan the schedule by function first and let the prep stay common.
11) I need the 5SS19N opening to be keyed or access controlled instead of free passage - what are the options?
The Marks USA 5SS19N is non-keyed with a passage function, so the lever always retracts the latch. For a keyed mechanical lever on the same style of opening, the Dorma C853 is a Grade 1 single cylinder keyed entry lever lockset covering 1-3/8 in to 2-1/4 in doors, and the Dorma C150 is a Grade 1 heavy-duty entry/office cylindrical lock over the same thickness range. For credential-based control, the Schlage NDEB ENGAGE is a Grade 1 heavy duty wireless Bluetooth cylindrical lock for 1-5/8 in to 2 in doors, and the TownSteel XCE-2000 is a Grade 1 heavy duty keypad electronic lockset for 1-3/4 in to 2 in doors. None of these is described as ligature-resistant, so confirm the opening is outside the patient-accessible area before substituting.
12) My door is 2 inches thick - will the Marks USA 5SS19N fit, and what passage lever covers thicker doors?
The Marks USA 5SS19N is built for a 1-3/4 in door thickness, so a 2 in door is outside what it is designed for. The Cal-Royal CAL30 is a Grade 1 passage/hall/closet lockset with a 1-3/8 in to 2 in door thickness range, and the Lockey 2830 mechanical pushbutton knob lock with auto-locking passage function covers 1-1/8 in to 2 in. Measure the door at the lock edge before ordering, since a mortise case has no adjustment for thickness the way a range-rated cylindrical unit does.
13) Can a TownSteel FCE-2000 or Schlage XE360M replace the Marks USA 5SS19N on a school door with special safety requirements?
They solve different problems. The TownSteel FCE-2000 is a Grade 1 heavy duty standalone motorized RFID classroom lockset for a 1-3/4 in door, and the Schlage XE360M is a Grade 1 wireless tubular lock with an offline push button classroom/storeroom function, also for a 1-3/4 in door - both are classroom-function locks for controlling who enters. The Marks USA 5SS19N is a non-keyed passage lock whose value is the ligature-resistant lever and rose, ADA compliance, and 3-hour fire rating. On a school with specialized safety requirements, a classroom intruder lock handles lockdown at the entry door while the 5SS19N suits an interior opening where free passage plus ligature resistance is the requirement.
14) Is a keyless pushbutton lock like the Lockey 2830 or Lockey 1600 an equivalent to the Marks USA 5SS19N?
No, and the difference matters in a behavioral health setting. The Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function and the Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset, both covering 1-1/8 in to 2 in doors. They are knob-operated, which is not an ADA-compliant lever operation, and they are not ligature-resistant designs. The Marks USA 5SS19N is a Grade 1 ADA compliant lever lockset with a ligature-resistant SS19 lever and rose. Use the Lockey units on utility or exterior gate style openings, not on a patient-accessible door.
15) What finish does the Marks 5SS19N come in?
One finish, US32D satin stainless steel, on a stainless steel body. On an institutional job that's usually what you want anyway, since satin stainless hides wear and matches the push plates, pulls and hinges already on the corridor. There's no painted or plated option to fall out of match a few years in.
