Key Features

  • Exceeds BHMA Grade 1 by 300%: Tested to over 3.6 million cycles, far surpassing standard Grade 1 requirements for exceptional long-term reliability in high-traffic institutional settings.
  • Unique Stainless Steel Clutch Mechanism: When locked, levers disengage from the retractor and interior mechanisms, swinging freely without resistance — dramatically reducing wear, eliminating lever droop, and extending service life.
  • Anti-Ligature Design: The LifeSaver lever profile is specifically engineered for institutional and behavioral health environments where anti-ligature compliance is required.
  • Cast Bronze Roller Bearing Retractors: All cylindrical lock chassis feature cast retractors on bronze roller bearings for smooth, durable operation across millions of cycles.
  • 3-Hour Fire Rated: Meets 3-hour fire rating requirements; available with 2-3/8" and 2-3/4" backsets for flexible installation.
  • Door Thickness Compatibility: Fits doors 1-5/8" to 1-7/8" thick; use K1904 spacer for 1-3/8" doors.
  • Comprehensive Latch & Strike Hardware: Includes Latch #1834 with 1-1/8" x 2-1/4" front, 9/16" throw, stainless steel nose, and Strike #1135 — a 4-7/8" ASA curved lip strike.
  • Solid Cast Zamac Levers: Levers feature solid cast zamac construction with 1/2" return (except 395 & 495 series) and thru-bolted roses at 3-7/16" diameter with spring-loaded 2-#10 thru-bolts.

Marks USA 195SSDW-32D – Frequently Asked Questions

1) Will the Marks USA 195SSB LifeSaver lockset fit a 1-3/4 inch commercial door?
Yes. The 195SSB is built for doors 1-5/8" to 1-7/8" thick, so a standard 1-3/4 inch commercial door sits right in the middle of the range. For a thinner 1-3/8 inch door you need the K1904 spacer, which is a separate item. Anything under 1-5/8 without that spacer is the wrong application.
2) Does the Marks 195SSB lock or key at all, or is it a free passage lever?
Free passage only. The 195SSB is ANSI function F75, non-keyed, and the latch retracts from the lever on both sides at all times. There is no cylinder, no privacy button, no thumbturn. Use it on corridors, hall doors, closets and anywhere you want a code-compliant lever with no locking. If you need the door to lock, this is the wrong function in the series.
3) What backset and strike does the Marks USA 195SSB institution lever use, and will it drop into an existing ASA prep?
The 195SSB is catalogued at a 2-3/4" backset, with 2-3/8" also offered, and ships with the #1834 latch (1-1/8" x 2-1/4" front, 9/16" throw, stainless nose) plus the #1135 strike, a 4-7/8" ASA curved lip. A frame already prepped for a 4-7/8 inch ASA strike takes it without new frame work. The 9/16 inch deadlocking throw needs a strike lip aligned to the door face, so if you are keeping an old strike, check the existing lip projection against the door position.
4) Can I use the Marks 195SSB LifeSaver lever on a 3-hour fire rated door in a hospital?
Fire rated, and UL Listed. The 195SSB carries a 3-hour fire rating and is ANSI/BHMA certified, and the lever is ADA compliant for accessible openings. That combination is what a healthcare or institutional spec normally calls for on a rated corridor door. Bear in mind it is a passage function, so it satisfies the rating but provides no security on that opening.
5) What makes the LifeSaver lever anti-ligature, and is it suitable for behavioral health rooms?
The LifeSaver lever profile is shaped specifically for institutional and behavioral health use where anti-ligature compliance is required, and it is built on the Marks Grade 1 LifeSaver platform. The clutch matters here too: when the lock is in its free-swinging state the lever disengages from the retractor rather than fighting it, which is part of why the mechanism survives abuse in psychiatric and correctional settings. Tested past 3.6 million cycles, 300 percent beyond BHMA Grade 1.
6) I need a lock on this door, not passage. What should I order instead of the 195SSB?
The 195SSB is non-keyed passage, so pick by the function you actually need. For a keyed entrance lever on a Grade 1 cylindrical chassis, the Dorma C853 is a single cylinder entry lockset covering 1-3/8" to 2-1/4" doors, and the Dorma C150 is a Grade 1 entry/office function on the same thickness range. For a bath or patient room privacy set, the Cal-Royal CAL20 is Grade 1 privacy at 1-3/8" to 2". For keypad access rather than keys, the Alarm Lock Trilogy DL2700 is a Grade 1 standalone electronic entrance lock that fits the same 1-5/8" to 1-7/8" doors the 195SSB does.
7) What is the closest Grade 1 passage lever equivalent to the Marks USA 195SSB from another manufacturer?
The Cal-Royal CAL30 Calypso is the nearest peer: an extra heavy duty Grade 1 cylindrical passage lockset with the same Passage/Hall/Closet function, so the latch is retracted by the levers at all times and there is no keying. The Marks USA 195SSB is also Grade 1 with Passage/Hall/Closet function. The difference is door thickness range: the CAL30 covers 1-3/8 inch to 2 inch doors, while the 195SSB fits 1-5/8 inch to 1-7/8 inch and uses the K1904 spacer to reach 1-3/8 inch. The 195SSB is the one built on the LifeSaver anti-ligature lever profile.
8) My doors are thicker than 1-7/8 inch. What cylindrical lever fits where the Marks USA 195SSB does not?
The Marks USA 195SSB covers 1-5/8 inch to 1-7/8 inch doors. For a thicker leaf, the Dorma C150 is a Grade 1 heavy-duty cylindrical entry/office lock rated to 2-1/4 inch, and the Dorma C853 Grade 1 entrance lever covers the same 1-3/8 inch to 2-1/4 inch range. If the opening needs passage function specifically, the Cal-Royal CAL30 Grade 1 passage lockset goes to 2 inch. All three are cylindrical, so the bore prep matches what the 195SSB uses.
9) Will the Marks 195SSB stand up to a school or dorm corridor where levers get hung on?
That is the specific failure this chassis is built against. Lever droop comes from weight and abuse loading the retractor; the stainless steel clutch lets the levers swing free of the retractor and interior mechanism instead, so the wear never reaches the working parts. The retractors themselves are cast bronze on roller bearings, and the roses are thru-bolted, 3-7/16" diameter with spring-loaded 2-#10 thru-bolts, so the trim does not loosen off the door. Over 3.6 million tested cycles behind it.
10) Is the Marks 195SSB a cylindrical lock or a mortise lock, and does that change my door prep?
Cylindrical, a bored lockset. It goes into a standard cross-bore through the door face with an edge bore for the latch, not a mortise pocket. That is the faster prep and the one most existing commercial doors already carry. If the door is currently mortise prepped, a cylindrical set will not fill that pocket and you would want a mortise lock instead.
11) Do I need to specify handing when ordering the Marks 195SSB LifeSaver passage lockset?
No handing to call out. It is an F75 passage function with levers that retract the latch from both sides at all times, so the chassis works either hand. The one thing to get right on the order is backset, 2-3/8" or 2-3/4", matched to the existing cross-bore centre on the door, and the K1904 spacer if the door is 1-3/8 inches thick.
12) Is there a lighter-duty passage lever to use instead of the Marks USA 195SSB on low-traffic interior doors?
Yes. The Orca Hardware OCL210 is a medium duty Grade 2 cylindrical passage lockset, and the Dorma CL701 is a Grade 2 non-keyed lever with Passage/Hall/Closet function. Both retract the latch at all times like the Marks USA 195SSB, which is Grade 1 and tested past 3.6 million cycles. Use the Grade 2 levers where the opening does not carry institutional traffic; specify the 195SSB where a Grade 1, 3-hour fire rated, UL Listed lockset is called for on the drawing.
13) Can a dummy lever be used in place of the Marks USA 195SSB?
No. A dummy trim is a fixed pull with no chassis and no latch, so it will not hold a door closed. The Dorma C501 and the Orca Hardware OCL2170 are both Grade 2 dummy levers, and the OCL2170 is a half dummy. The Marks USA 195SSB is a Grade 1 cylindrical lockset with a working latch: Latch #1834 with a 1-1/8 inch by 2-1/4 inch front, 9/16 inch deadlocking throw, and Strike #1135 4-7/8 inch ASA curved lip. Use a dummy only on an inactive leaf or a fixed panel; use the 195SSB on any leaf that latches.
14) When would I specify an electronic cylindrical lock instead of the Marks USA 195SSB?
When the opening needs credentials or an audit trail, which a mechanical passage lever cannot provide. The Marks USA 195SSB is a Grade 1 mechanical cylindrical lockset, not keyed, with the latch retracted by the levers at all times. For controlled access on the same cylindrical prep, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic entrance lock with a digital keypad, 100 user codes, and SFIC compatibility on 1-5/8 inch to 1-7/8 inch doors, the same thickness band the 195SSB covers. The Schlage NDEB is a Grade 1 heavy duty ENGAGE wireless lock over Bluetooth Low Energy for 1-5/8 inch to 2 inch doors, and the TownSteel XCE-9000 is a Grade 1 heavy duty electronic classroom intruder lockset with a keypad for 1-3/4 inch to 2 inch doors.
15) Is the Stanley QTL230E passage lever the same thing as the Marks USA 195SSB?
They are not interchangeable. The Stanley Security QTL230E is a Grade 2 passage lever with a Sierra bent lever and small rose, an adjustable square latch, and a 4-7/8 inch by 1-1/4 inch ANSI strike. The Marks USA 195SSB is Grade 1 with the LifeSaver anti-ligature lever profile and ships with Latch #1834, a 9/16 inch deadlocking throw, and the Strike #1135 4-7/8 inch ASA curved lip. Where a spec calls for anti-ligature trim in a behavioral health or detention opening, the lever profile is the deciding difference, not the chassis.
16) I need to standardize a facility on one cylindrical platform. Which peers share the Marks USA 195SSB backset and strike?
The Marks USA 195SSB uses a 2-3/4 inch backset with the 4-7/8 inch ASA curved lip Strike #1135 and a 1-1/8 inch by 2-1/4 inch latch front, and is also available in a 2-3/8 inch backset. The Stanley Security QCL150 entry lever also uses a square 2-3/4 inch backset latch with a 4-7/8 inch by 1-1/4 inch ASA strike, and the Stanley QTL230E uses the same 4-7/8 inch by 1-1/4 inch ANSI strike. Confirm the strike lip and cutout against the existing frame prep before mixing platforms, since the 195SSB lip is curved.
17) What finish does the Marks USA 195SSB institution lever come in?
US32D satin stainless steel, which is the standard institutional finish and what matches most existing hospital, school and correctional hardware. The solid cast zamac levers carry a 1/2" return. If your building is standardized on satin chrome trim, US32D reads closely alongside it on the same corridor.
18) Can a Lockey keyless pushbutton lock replace the Marks USA 195SSB?
Only if the opening is meant to control access rather than stay free-swinging. The Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function for 1-1/8 inch to 2 inch doors, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset over the same thickness range. Both are knob trim, not lever trim. The Marks USA 195SSB is ADA compliant Grade 1 lever hardware with the latch retracted by the levers at all times, which is what an accessible egress path in a healthcare or school corridor is specified for.
