Marks USA 5SS19J-32D – Frequently Asked Questions

1) Will the Marks USA 5SS19J LifeSaver lockset fit a 1-3/4 inch door?
Yes, 1-3/4 inches is what the 5SS19J LifeSaver is built for, and it is a single-thickness lockset rather than an adjustable one. The case measures 4-3/16 x 6-1/16 x 7/16 inches with a 2-3/4 inch backset, so the door needs that deeper prep and not the 2-3/8 inch backset common on residential doors. If the openings in the building are thicker than 1-3/4 inches, a lockset with a stated range is the better route: the Dorma C150 covers 1-3/8 to 2-1/4 inches and the Cal-Royal CAL30 covers 1-3/8 to 2 inches.
2) What is an anti-ligature lever lock and where do I actually need one?
An anti-ligature lever is shaped so lines, laces, cords and similar items cannot be tied off to it. The Marks USA 5SS19J LifeSaver was developed for behavioral health care institutions for exactly that reason: life safety, security, managed liability and accident prevention. It is the specification for psychiatric and mental health units, hospital behavioral wings, correctional and detention work, and the institutional buildings around them. On a normal office or classroom door where ligature risk is not a concern, a standard lever lockset does the same job for less prep fuss.
3) Does the Marks USA 5SS19J LifeSaver come with a strike, and will it latch into my existing frame?
A curved lip strike with a 4-7/8 inch strike plate height is included, which is the standard ANSI strike height found in most commercial hollow metal frames. The latch throws 9/16 inch and is a deadlocking latch, so the frame needs a square, properly aligned strike pocket at that depth. If your frames are already prepped for a 4-7/8 inch ANSI strike, the included plate drops straight in. Shallow or worn residential-style strikes will not hold a 9/16 inch throw reliably.
4) Is the Marks USA 5SS19J LifeSaver ANSI Grade 1 and can I use it on a fire door?
Grade 1, meeting or exceeding the operational and security tests of ANSI A156.13-2005 for Series 5000, with BHMA certification and CULUS listing. It is fire rated for use in compliant fire door assemblies and it is ADA compliant, so it covers the three boxes an institutional spec usually asks for at once: grade, fire, accessibility. Grade 1 is the heaviest commercial duty level in the ANSI/BHMA scheme, which is what you want on a behavioral health or corridor door seeing constant traffic.
5) I need access control or audit trail on a behavioral health door, not a mechanical lock. What else is there?
The 5SS19J LifeSaver is a mechanical anti-ligature lockset, so there is no keypad, credential reader or audit log in it. If the requirement is electronic, the Grade 1 options on 1-3/4 inch doors include the TownSteel FCE-2000 Series, a standalone motorized RFID classroom lockset, the TownSteel FCE-4000 Series RFID intruder classroom lockset, and the Schlage XE360M, a wireless push button classroom/storeroom lock with a mobile reader. For audit trail specifically, the Alarm Lock T3 DL3200 Series is a Grade 1 keypad lock with audit trail. None of those carry the anti-ligature lever geometry, so on a genuine ligature-risk door the mechanical LifeSaver is still the right call.
6) Which lock should I use instead of the Marks USA 5SS19J when the facility wants keypad or credential access instead of a keyed classroom lock?
The Marks USA 5SS19J LifeSaver is a mechanical Grade 1 lockset. For credential-based access on a classroom opening, the TownSteel XCE-2000 Series is a Grade 1 heavy duty electronic classroom cylindrical lockset with a keypad for doors 1-3/4 to 2 inches, and the TownSteel XCE-9000 Series adds classroom intruder function over the same 1-3/4 to 2 inch door range. The TownSteel FCE-4000 Series is an RFID electronic intruder classroom lockset for 1-3/4 inch doors. All three change the credential from a Marks C key to a code or card.
7) Do I have to order the Marks USA 5SS19J LifeSaver handed for a left or right door?
No handing to specify. The 5SS19J LifeSaver is non-handed, so one part number covers left and right hand openings in either swing. For a facilities group that keeps spares on the shelf, that means a single stock item instead of two, and no wrong-hand returns from the field.
8) What finish does the Marks USA 5SS19J LifeSaver come in?
One finish only: US32D satin stainless steel, in the SS19 lever style. Stainless holds up to the cleaning chemicals and wipe-down schedules used in healthcare and behavioral units, and US32D is the finish most institutional door hardware schedules are already written around, so it will sit consistently next to existing stainless pulls, push plates and hinges.
9) What size is the faceplate prep for the Marks USA 5SS19J LifeSaver?
The front measures 1-1/8 by 2-1/4 inches, and the lock case behind it is 4-3/16 x 6-1/16 x 7/16 inches. Compare those numbers against the existing mortise pocket before you pull the old lock: a door already cut for a different case size or a different front will need the edge prep reworked, and on a fire rated door that is not a field modification you want to improvise.
10) How does the lever on the Marks USA 5SS19J LifeSaver hold up to abuse?
It uses a clutch lever running on needle bearings, in a steel case. The clutch is the part that matters in an institutional setting: force applied to a locked lever turns the lever without driving the internal mechanism, so someone hanging on it or forcing it down does not break the lock. The needle bearings keep the lever action smooth through high cycle counts rather than developing the sag you get from a plain bushing.
11) Will a Grade 2 passage lever work in place of the Marks USA 5SS19J on an institutional corridor door?
They are different duty levels. The Marks USA 5SS19J LifeSaver is Grade 1 and rated commercial. The Orca Hardware OCL210 passage cylindrical lockset is Grade 2 medium duty, and the Dorma CL701 is a Grade 2 passage single dummy non-keyed lever. Those carry a passage function but at a lower grade and, in the CL701 case, as dummy trim with no latch operation, so neither is a like-for-like replacement for a Grade 1 institutional lockset.
12) What is a simpler Grade 1 lever lockset than the Marks USA 5SS19J for a door that only needs passage or privacy?
The Marks USA 5SS19J LifeSaver is a Grade 1 anti-ligature lockset for a 2-3/4 inch backset. Where the opening only needs passage, the Cal-Royal CAL30 Calypso Series is a Grade 1 extra heavy duty passage lockset for doors 1-3/8 to 2 inches. For privacy, the Cal-Royal CAL20 Calypso Series is a Grade 1 extra heavy duty privacy lock over the same 1-3/8 to 2 inch door range. Both are mechanical, non-anti-ligature levers with a wider door thickness range than the 1-3/4 inch door the 5SS19J is built for.
13) Which cylindrical locks look like alternatives to the Marks USA 5SS19J but will not fit a 1-3/4 inch institutional door?
Door thickness rules several of them out. The Marks USA 5SS19J LifeSaver is built for a 1-3/4 inch door. The Alarm Lock Trilogy T2 DL2700 and the Trilogy 4100 both list a 1-5/8 to 1-7/8 inch door range, so they do cover 1-3/4 inch, but the Dorma C501 single dummy stops at 1-3/4 inch as dummy trim only, and the Lockey E985 and E995 electronic keypad lever locks run 1-3/8 to 1-3/4 inch with no margin above it. Confirm the leaf measures before ordering any of them against a 5SS19J opening.
14) What should I use instead of the Marks USA 5SS19J on an opening that needs to be released from an access control panel?
The Marks USA 5SS19J LifeSaver is a mechanical Grade 1 lockset operated by key and lever. For an opening wired to a panel, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock running dual voltage 12/24VDC for doors 1-3/4 to 2 inches. The SDC E75 Series is a battery-powered electronic cylindrical lockset with keypad access control for doors 1-3/4 to 2-1/8 inches, which covers standalone openings where no wiring is run.
15) Is the Kwikset SmartCode 912TNL a substitute for the Marks USA 5SS19J in a commercial building?
The Marks USA 5SS19J LifeSaver is a Grade 1 lockset rated commercial, ADA compliant, ANSI/BHMA and UL Listed. The Kwikset 912TNL ZW500 SmartCode is an electronic Tustin lever with Z-Wave technology, keyed one side, for doors 1-3/8 to 2 inches. It is a home-automation credential lever, which is a different build and specification basis than a Grade 1 institutional lockset carrying BHMA and UL listing.
16) Is the Marks USA 5SS19J LifeSaver rated for commercial use or is it a residential lock?
Strictly commercial. It is graded, certified and built for institutional service, with a steel case and a Grade 1 ANSI/BHMA rating, and the applications it is written for run from behavioral health and hospital facilities to schools, correctional work, and government and municipal buildings. It is not a residential product and the 2-3/4 inch backset alone puts it outside typical house door prep.
17) What Grade 1 keypad lock covers a classroom opening if the Marks USA 5SS19J anti-ligature lever is more than the job needs?
The Marks USA 5SS19J LifeSaver is a Grade 1 lockset built around an anti-ligature lever for behavioral health use. On a standard classroom door, the Accentra nexTouch NTB613 is a Grade 1 cylindrical keypad lock with pushbutton entry, the BEST 9KZ EZ Series is an electronic keypad cylindrical lock with key override, and 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 for doors 1-5/8 to 1-7/8 inches. Each trades the keyed anti-ligature lever for code entry.
