Marks USA 5SS19L-32D – Frequently Asked Questions

1) Is this Marks LifeSaver lock actually a locking bathroom lock, or does it stay unlocked?
The 5SS19L is an ANSI F75 function: the latch is retracted by the levers at all times, so it operates as passage, hall or closet. There is no privacy or occupancy indicator on the inside. If you need a behavioral health restroom door that can be secured from inside, an F75 will not do it. A privacy function lockset such as the Cal-Royal CAL20 is the privacy equivalent in a Grade 1 cylindrical.
2) Do I have to order the Marks 5SS19L handed for a left or right swing door?
No handing to specify. The 5SS19L LifeSaver is non-handed and installs on a door of either swing without modification, so one part number covers every opening in the building. That is worth something on an institutional stocking list, since you carry one SKU instead of two.
3) Will the 5SS19L latch work with the strike already in my frame?
The 5SS19L ships with a 4-7/8 inch curved lip strike and the latch has a 9/16 inch throw. If your frames are already prepped for a 4-7/8 inch ANSI strike, which most hollow metal institutional frames are, it drops in. Frames cut for a smaller T-strike or a 2-3/4 inch face will need new prep. The latch is deadlocking, so the deadlatch plunger has to land on the strike face, not in the cutout, or it will not deadlock.
4) What makes the SS19 lever anti-ligature, and where should I be using it?
The SS19 lever and rose are shaped so there is no protruding point to tie a cord or garment to, which is the whole reason the LifeSaver line exists. It is aimed at behavioral health units, psychiatric wards, detention and correctional facilities, and institutional restroom and shower rooms. A standard bent or return lever on those doors is a ligature point, and that is the substitution a facility usually gets wrong.
5) If the restroom needs an actual privacy function with an inside turn, what Grade 1 lever should be used instead of the Marks USA 5SS19L?
Look at the Cal-Royal CAL20 Calypso, a Grade 1 extra heavy duty privacy/bed/bath cylindrical lock fitting doors 1-3/8 in to 2 in. The Marks USA 5SS19L is set up as a passage/hall/closet function with the latch retracted by levers at all times, so it does not hold the door locked against a user inside. Where the specification calls for an occupant-operated privacy lock rather than a free-swinging ligature-resistant lever, the CAL20 is the function match.
6) Does the 5SS19L come keyed, and what keyway does it use?
It is catalogued as non-keyed because the F75 function retracts the latch from either side at all times. The lock uses the Marks C keyway and two keys are supplied, so if you are standardizing a facility on Marks C you stay on the same key system across your other Marks cylinders.
7) Can I put access control or a keypad on these behavioral health doors instead?
Not with the 5SS19L, which is purely mechanical with a clutch lever and needle bearings. If a door needs credentialed access, TownSteel's XCE-2000 Series is a Grade 1 keypad cylindrical for 1-3/4 to 2 inch doors, and the Schlage CO-100 keypad lock is a Grade 1 privacy function unit for 1-3/4 inch doors. Neither is described as ligature resistant, so keep those off the patient-side openings and use them on staff and service doors.
8) Is there a Grade 1 electronic privacy lock that would cover a behavioral health restroom instead of the Marks USA 5SS19L?
The Schlage CO-100-CY-40-KP is a Grade 1 heavy duty standalone electronic cylindrical lock with a privacy function and keypad, built for a 1-3/4 in door - the same door thickness the Marks USA 5SS19L is designed around. The trade is mechanical versus electronic: the 5SS19L is a mechanical Grade 1 lockset with a ligature-resistant lever and needs no power or credential management, while the CO-100 adds keypad access and battery service. Facilities that want access control at the opening go with the CO-100; facilities that want the ligature-resistant lever and no electronics stay with the 5SS19L.
9) Can a dummy lever such as the Dorma C501 be used where the Marks USA 5SS19L is specified?
No - a dummy is trim only. The Dorma C501 is a Grade 2 single dummy keyless lever trim with no latch, and the Orca OCL2170 is a Grade 2 half dummy lever in the same category. The Marks USA 5SS19L is a Grade 1 lockset with a deadlocking latch, a 9/16 in throw, and a 4-7/8 in curved lip strike, so it actually latches the door. Dummy trim belongs on an inactive leaf or a pull-only door, never on the opening the 5SS19L is specified for.
10) What should be used instead of the Marks USA 5SS19L if the restroom door needs to be keyed for staff entry?
The 5SS19L is a non-keyed passage/hall/closet lockset, so keyed entry is a different function. Grade 1 keyed options include the Dorma C853 single cylinder entry lever, which fits doors 1-3/8 in to 2-1/4 in, and the Dorma C150 entry/office lock over the same door range. If the requirement is credential-based rather than key-based, the Schlage NDEB ENGAGE wireless Grade 1 lock covers storeroom, office, privacy and apartment functions on doors 1-5/8 in to 2 in.
11) Is a keyless pushbutton knob lock like the Lockey 2830 an alternative to the Marks USA 5SS19L?
Only where the opening does not carry an institutional or ADA requirement. The Lockey 2830 is a mechanical pushbutton keyless knob lock with a passage function fitting doors 1-1/8 in to 2 in, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset over the same door range. Both are knob-operated. The Marks USA 5SS19L is a lever lockset that is ADA compliant and Grade 1 with a ligature-resistant SS19 lever, which is what behavioral health and detention specifications call for. Knob operation is the deciding difference on any door where ADA lever operation is required.
12) For a school restroom or classroom door, does the Marks USA 5SS19L or a TownSteel classroom lockset fit better?
It depends on whether the door needs to lock down. The Marks USA 5SS19L is a passage/hall/closet function with the latch retracted by levers at all times, which suits a secure institutional restroom where the door should never trap an occupant. The TownSteel FCE-4000 and XCE-9000 are Grade 1 heavy duty classroom intruder locksets - FCE-4000 with RFID, XCE-9000 with a keypad - intended for classroom doors that must be secured from inside during a lockdown. Restroom and shower openings take the 5SS19L; classroom entry doors under a lockdown policy take one of the TownSteel intruder locks.
13) What finish does the Marks 5SS19L come in?
One finish: US32D satin stainless steel. The body is stainless steel over a stamped steel 1-1/16 inch case, which is why it holds up in wet restroom and shower environments where a plated brass lock would pit.
