Marks USA 5SS19A-32D-RH – Frequently Asked Questions

1) Will the Marks USA 5SS19A LifeSaver fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That is exactly the prep it is built for. The 5SS19A runs a 2-3/4 inch backset and is specified for 1-3/4 inch door thickness, which is the standard commercial door. The front measures 1-1/8 x 2-1/4 inches. If your existing openings are prepped at 2-3/8 inch backset, this is not the lock for them.
2) Do I have to order the Marks 5SS19A anti-ligature lockset left hand or right hand?
The lock itself is non-handed, so swing direction does not change how it works. Ordering still asks you to pick LH or RH, and both are offered in US32D satin stainless steel. Pick the hand that matches the door and you are covered either way.
3) What does the F75 storeroom function actually do on a patient room or supply door?
Outside lever stays locked at all times and only a key retracts it from the corridor side. The inside lever always retracts the latch, so anyone in the room walks out freely without a key. That is what makes F75 the usual pick for storerooms, med rooms, and behavioral health spaces where you want free egress but no uncontrolled entry.
4) Will the Marks 5SS19A latch into the strike already in my frame?
Latch throw is 9/16 inch and it is a deadlocking latch, paired with a curved lip strike at 4-7/8 inch height. A 4-7/8 inch ANSI strike prep in the frame will take it. If your frame carries a shorter T-strike or a 2-3/4 inch box strike, plan on swapping the strike when you hang the lock.
5) Is the Marks USA LifeSaver 5SS19A approved for a fire rated opening and does it meet ADA?
Both. The 5SS19A is fire rated for use on rated door assemblies and is CULUS listed, and the lever trim meets ADA requirements for operable hardware. It is certified to ANSI/BHMA and carries a Grade 1 rating, which is the heavy duty commercial tier institutional specs usually call for.
6) What are the case dimensions I need to cut into the door for the Marks 5SS19A?
The steel case measures 4-3/16 x 6-1/16 x 7/16 inches, with a 1-1/8 x 2-1/4 inch front. That is a mortise pocket, not a bored 161 prep, so a door already drilled for a cylindrical lockset will need different machining.
7) My doors range from 1-3/8 to 2 inches. Can I standardize the whole building on the 5SS19A?
No. The 5SS19A is a single-thickness lock built for 1-3/4 inch doors, so it will not cover a mixed fleet. For the openings outside that, the Cal-Royal CAL20 privacy and CAL30 passage sets are Grade 1 and handle 1-3/8 to 2 inch doors, and the Dorma C150 entry/office lock covers 1-3/8 to 2-1/4 inch. Keep the LifeSaver on the doors that genuinely need ligature-resistant trim.
8) What is the closest Grade 1 storeroom-function lever lock to the Marks USA 5SS19A if an anti-ligature lever is not required?
The Schlage NDEB is a Grade 1, heavy duty cylindrical lock offered in storeroom, office, privacy and apartment functions, fitting doors 1-5/8 inch to 2 inch thick. It holds the same Grade 1 rating as the 5SS19A, which carries ANSI F75 storeroom function on a 2-3/4 inch backset. The difference is the trim and the credential: the NDEB is a wireless Bluetooth Low Energy lock with mobile credentials and a conventional lever, while the 5SS19A is a keyed mechanical unit on the Marks C keyway with the ligature-resistant SS19 lever and rose. On a behavioral health opening the ligature-resistant trim is the reason to stay with the 5SS19A; on a back-of-house storeroom where trim shape does not matter, the NDEB covers the same function and grade.
9) Is the Alarm Lock Trilogy DL2700 a substitute for the Marks USA 5SS19A in a behavioral health facility?
No. The 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 inch to 1-7/8 inch thick. It matches the 5SS19A on Grade 1 but the trim is a conventional keypad lever, not the ligature-resistant SS19 lever and rose the 5SS19A uses. On patient rooms and other openings where ligature resistance is the specification, the DL2700 does not answer it; on a staff or administrative door where code-based access is the requirement, it does.
10) What makes the LifeSaver SS19 lever anti-ligature, and where should it be used instead of a standard lever?
The SS19 lever and rose trim are shaped to resist ligature attachment, which is the reason it goes on behavioral health, psychiatric, and correctional doors where a standard bent or return lever gives a tie-off point. On ordinary office or classroom openings a conventional Grade 1 lever such as the Cal-Royal CAL30 passage set does the job. Anti-ligature trim is a safety requirement, not an upgrade you buy everywhere.
11) What keyway does the Marks 5SS19A use and how many keys come with it?
It runs the Marks C keyway and ships with 2 keys. If your facility is keyed in Schlage C or another system, this will not key into that existing bitting, so factor that into a standardization plan before you roll it across a building.
12) I need keypad or card access on a behavioral health door instead of a key. What else is there?
The 5SS19A is a mechanical key-operated lock with no electronic option. For credential access on the same kind of opening, the Schlage NDEB ENGAGE wireless Grade 1 cylindrical lock covers storeroom function on 1-5/8 to 2 inch doors, and the TownSteel FCE-2000 is a Grade 1 motorized RFID lockset for 1-3/4 inch doors. Neither of those carries the anti-ligature lever trim, so on a patient room where ligature resistance is the reason for the spec, stay with the LifeSaver.
13) Is the Marks 5SS19A durable enough for a high traffic institutional corridor?
Grade 1 is the top ANSI/BHMA commercial tier, and the 5SS19A backs it with a steel mortise case, a clutch lever, and needle bearings. The clutch matters on abuse-prone doors: force on a locked outside lever spins the lever rather than loading the internal works. Most of the cylindrical alternatives in this class from Orca and Dorma's C500 and CL700 lines are Grade 2, a lighter duty rating.
14) Which lock should be used on a corridor or closet door that needs no key at all, alongside Marks USA 5SS19A storeroom openings?
The Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lockset in passage/hall/closet function for doors 1-3/8 inch to 2 inch thick. It matches the 5SS19A on Grade 1 but carries no cylinder, so the latch is always free from both sides. The 5SS19A is a keyed storeroom lock whose outside lever stays locked and is released by key only. Use the CAL30 on doors that only need latching and the 5SS19A where the opening has to stay secured.
15) What lock handles a patient bathroom or bedroom door that needs privacy rather than the storeroom function of the Marks USA 5SS19A?
The Schlage CO-100 is a Grade 1 heavy duty standalone electronic cylindrical lock in privacy function with keypad and cylinder options, built for 1-3/4 inch doors. The Cal-Royal CAL20 is a mechanical alternative, Grade 1 extra heavy duty privacy for 1-3/8 inch to 2 inch doors. Both are privacy function, locked from the inside by the occupant; the 5SS19A is ANSI F75 storeroom, where the outside lever is always locked and opens by key. Both the CO-100 and the 5SS19A suit a 1-3/4 inch door, which is what the 5SS19A is designed for.
16) What is the difference between the Marks USA 5SS19A and the Dorma C853 for a secured institutional opening?
The Dorma C853 is a Grade 1 entry keyed single cylinder lever lockset from the C800 Series, covering doors 1-3/8 inch to 2-1/4 inch thick, so it spans a wider range of door thicknesses than the 5SS19A, which is built for 1-3/4 inch. Function is the real split: the C853 is entrance function, where the outside lever can be left unlocked by the occupant, while the 5SS19A is ANSI F75 storeroom with the outside lever always locked and a deadlocking latch. For a room that must never be left open, the 5SS19A function is the one to spec.
17) For a classroom door in a school that also uses Marks USA 5SS19A locks, what covers a classroom-intruder function?
The TownSteel XCE-9000 is a Grade 1 heavy duty electronic classroom intruder cylindrical lockset with keypad for doors 1-3/4 inch to 2 inch thick, and the FCE-4000 is a Grade 1 heavy duty RFID electronic intruder classroom lockset for 1-3/4 inch doors. Both are classroom function, letting a teacher secure the door from inside without opening it. The 5SS19A is ANSI F75 storeroom and is locked and unlocked from the outside by key, so it does not provide inside lockdown. A school can run the 5SS19A on storage and mechanical rooms and the classroom-function units on instructional spaces.
18) Which alternative to the Marks USA 5SS19A works on doors thinner or thicker than 1-3/4 inch?
The 5SS19A is built for a 1-3/4 inch door. When the opening is outside that, the Dorma C150 is a Grade 1 heavy duty cylindrical lock in entry/office function covering 1-3/8 inch to 2-1/4 inch, and the Cal-Royal CAL30 covers 1-3/8 inch to 2 inch in passage function. Both hold Grade 1. Function differs from the 5SS19A storeroom in each case, so confirm the opening can accept entry/office or passage before substituting on thickness alone.
19) Is the SDC Electra 7200 an option where the Marks USA 5SS19A is installed but the door needs to release from an access control system?
The SDC Electra 7200 Series is a solenoid controlled cylindrical lock running on dual voltage 12/24VDC, for doors 1-3/4 inch to 2 inch thick, which includes the 1-3/4 inch door the 5SS19A is built for. It releases electrically from a card reader or control panel; the 5SS19A is a mechanical keyed storeroom lock with no electrical connection. Where an opening has to tie into access control, the 7200 answers it, but it brings conventional trim rather than the ligature-resistant SS19 lever.
20) What finish does the Marks LifeSaver 5SS19A anti-ligature lockset come in?
US32D satin stainless steel, in left hand and right hand. That is the finish institutional specs default to because it hides wear and cleans up under hospital disinfectants, and it lets the lock sit alongside stainless push plates and pulls without a mismatch.
21) When does a keyless pushbutton lock make sense instead of the keyed Marks USA 5SS19A?
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 thick, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset for the same 1-1/8 inch to 2 inch range. Both run on a code with no key and no battery. The 5SS19A is keyed to the Marks C keyway and ships with two keys, and it is a lever, which is what makes it ADA compliant. Knob trim does not meet the ADA lever requirement, so on accessible openings the 5SS19A lever is the one to hold.
