Marks USA 195DA Vestibule Clutched Lever Lockset — Grade 1, Marks C Keyway, 6 Pin, ADA Compliant

The Marks USA 195DA is a Grade 1 commercial-grade vestibule clutched lever lockset from the 195 Series, engineered for demanding high-traffic applications. Supplied with 6-pin cylinders in Marks "C" keyway and 2 nickel-silver keys, this lockset features a cast stainless steel retractor with bronze roller bearings for ultra-high strength, smooth operation, and long life. The innovative clutch mechanism disengages the outside lever when locked, allowing it to turn freely without opening the latch — dramatically reducing torque stress compared to rigid lever designs. Rated for doors 1-5/8" to 1-7/8" thick (K1704 spacer required for 1-3/8" doors), this UL Listed, 3-hour fire-rated lockset is ADA compliant and ANSI/BHMA certified for professional commercial installations.

Key Features

  • Exceptional Torque Resistance: Withstands torque of 1,800 inch-pounds — over twice the ANSI/BHMA (1996) test value — for superior protection against forced entry and abuse.
  • Outstanding Cycle Durability: Life tested over 6 million cycles and fully operational after testing, ensuring long-term reliability in the highest-traffic commercial environments.
  • Clutch Mechanism Protection: "The Clutch" disengages the outside lever when locked, allowing it to turn freely without actuating the latch, reducing torque on the lever and preventing the failures common to rigid lever designs.
  • Breakaway Handle Design: American and Crescent design breakaway handles protect against excessive abuse and vandalism.
  • Backset & Latch Specifications: Standard 2-3/4" backset; optional 2-3/8", 3-3/4", and 5" backsets available. Latch #1834 features a 1-1/8" x 2-1/4" front, 9/16" throw, and stainless steel nose.
  • Door Thickness Compatibility: Fits doors 1-5/8" to 1-7/8" thick; use K1704 spacer for 1-3/8" doors.
  • Electrified Function Options: 100% duty cycle; 24V/AC supplied with bridge rectifier; 24V/DC at 0.21 Amps standard; 12V/DC optional. Request to Exit (REX) switch available: single pole, double throw, 3 amp, 125 AC, wired normally open or normally closed.
  • Vibration-Proof Thru-Bolt Mounting: Only two #10 epoxy-coated thru-bolts required for secure, vibration-proof installation. Rose is thru-bolted, 3-7/16" diameter, spring loaded.
  • Lever & Strike Construction: Levers are solid cast Zamac with 1/2" return. Strike #1135 features a 4-7/8" ASA curved lip.
  • Wide Function Availability: Available in Vestibule, Passage, Privacy, Classroom, Storeroom, Institution, Corridor, Hospital/Privacy, Classroom Intruder, and many more functions.

Marks USA 195DA/26D – Frequently Asked Questions

1) Will the Marks USA 195DA lever lockset fit a 1-3/8 inch door?
Not on its own. The 195DA is built for doors 1-5/8 to 1-7/8 inches thick, which covers standard 1-3/4 inch commercial doors. For a 1-3/8 inch door you need the K1704 spacer with the lock. If you are ordering for a building with a mix of older 1-3/8 interior doors and 1-3/4 commercial doors, order the spacer for the thin ones.
2) What backset does the Marks 195DA come with, and can I get it for a 5 inch backset door?
Standard backset on the 195DA is 2-3/4 inches, which is the usual commercial bore location. Optional 2-3/8, 3-3/4 and 5 inch backsets are available, so a wide-stile or unusual prep can be covered, but the backset has to be specified when you order. Measure from the door edge to the center of the cross bore before you pick.
3) Will the Marks 195DA latch work with the strike already in my frame?
The 195DA uses the #1834 latch with a 1-1/8 x 2-1/4 inch front and a 9/16 inch deadlocking throw, and ships with the #1135 strike, a 4-7/8 inch ASA curved lip. If your frame already has a 4-7/8 ASA strike prep, it drops in. If your existing strike is the smaller 1-1/8 x 2-3/4 T-strike, the lip and cutout will not line up and you should plan on the ASA strike and frame prep. The 9/16 throw is short, so the strike has to be aligned properly for the latch to deadlock.
4) What does the vestibule function on the Marks 195DA actually do?
Vestibule function keeps the outside lever normally locked and unlocked by key, with the inside lever always free for egress. The 195DA carries the ANSI F75 function and a deadlocking latch. The clutch is what makes it survive a vestibule: when the outside lever is locked it spins free instead of fighting the retractor, so somebody yanking on it at a lobby door is not loading the lock train.
5) Is the Marks USA 195DA fire rated and ADA compliant for a school or hospital corridor?
Yes on both. The 195DA is UL Listed with a 3-hour fire rating and is ADA compliant, and it is ANSI/BHMA certified at Grade 1 for commercial use. The lever return is 1/2 inch, which is the detail an inspector looks at on ADA lever hardware. For a healthcare or education facility standardizing on one lock, the 195 Series also covers passage, privacy, classroom, storeroom, institution, corridor and hospital privacy functions, so the same lock body and lever run through the building.
6) What is a Grade 1 mechanical passage lever equivalent to the Marks USA 195DA?
The Cal-Royal CAL30 is a Grade 1 passage/hall/closet cylindrical lockset from the Calypso series and covers the same non-keyed lever duty as the Marks USA 195DA, which is also Grade 1 and non-keyed with a cylindrical lock chassis. The CAL30 lists a door thickness range of 1-3/8 inch to 2 inch, so it spans thinner doors directly, while the 195DA uses a K1704 spacer to reach 1-3/8 inch doors. Both are mechanical, so neither adds batteries or wiring to the opening.
7) What should I use instead of the Marks USA 195DA if the door needs a keyed entrance function?
The Marks USA 195DA is non-keyed, with the latch retracted by the levers at all times. For an opening that has to lock with a key, the Dorma C853 is a Grade 1 entrance-function keyed lever lockset with a single cylinder from the C800 series, fitting doors 1-3/8 inch to 2-1/4 inch, and the Dorma C150 is a Grade 1 heavy-duty cylindrical lock in entry/office function with the same 1-3/8 inch to 2-1/4 inch range. The Orca Hardware OCL250 is a Grade 2 entrance cylindrical lockset for lighter openings.
8) What keyway and how many pins does the Marks 195DA use, and can I key it into my existing system?
The 195DA ships with 6-pin cylinders in the Marks "C" keyway and two nickel-silver keys. If your building is already on Marks C, it keys straight into the system. If your masterkey system is on a Schlage C, Kwikset or a restricted keyway, the supplied cylinder will not pin to it and you will need cylinders in your keyway instead.
9) How is the Marks 195DA lockset mounted, and will it loosen on a high traffic door?
Two #10 epoxy-coated thru-bolts hold it, and the 3-7/16 inch rose is thru-bolted and spring loaded, so the trim is clamped through the door rather than screwed to a surface. That is what keeps it from working loose under vibration on a door cycling all day. Inside, a cast stainless steel retractor on bronze roller bearings carries the load, tested past 6 million cycles and rated to 1,800 inch-pounds of torque.
10) Can the Marks 195DA be electrified for access control, and what voltage does it need?
Yes. Electrified 195 Series functions run 100 percent duty cycle, 24V DC at 0.21 amps standard, with 12V DC optional; the 24V AC version comes with a bridge rectifier. A request-to-exit switch is available, single pole double throw, 3 amp at 125 AC, wired normally open or normally closed. Specify the voltage, the fail-safe or fail-secure behavior you want, and whether you need the REX at order time. If you would rather not run wire to the door, a standalone battery lock like the Alarm Lock Trilogy DL2700 covers the same 1-5/8 to 1-7/8 inch door range.
11) Should I use a mechanical lever lockset like the Marks 195DA or go with an electronic keypad lock?
Pick the 195DA when the opening needs a keyed mechanical lock that never needs batteries and takes abuse: Grade 1, 1,800 inch-pound torque rating, 6 million cycles, no code management. Go electronic when you need to change access without rekeying or want an audit trail. Among keypad cylindrical locks in the same Grade 1 class, the Alarm Lock Trilogy T2 DL2700 handles 100 user codes on 1-5/8 to 1-7/8 inch doors, the Alarm Lock T3 DL3075 adds audit trail, and the Schlage NDEB ENGAGE lock is wireless Bluetooth for 1-5/8 to 2 inch doors. All of them still need batteries and someone to manage the credentials.
12) What else could I use if the 195DA does not fit my door thickness?
The 195DA covers 1-5/8 to 1-7/8 inches. If your doors fall outside that, the Cal-Royal CAL30 Calypso passage lock and CAL20 privacy lock are Grade 1 cylindrical locks rated 1-3/8 to 2 inches, and the Dorma C853 entry lever and C150 entry/office lock are Grade 1 rated 1-3/8 to 2-1/4 inches. Those cover both thin older doors and thicker doors the Marks will not reach without the K1704 spacer.
13) Is a Grade 2 cylindrical lockset good enough, or do I need Grade 1 like the Marks 195DA?
On a vestibule, corridor or classroom door cycling hundreds of times a day, Grade 1 is what the spec usually calls for, and the 195DA is Grade 1 with a 1,800 inch-pound torque rating and 6 million cycles behind it. Grade 2 is fine on low-traffic interior openings, closets, offices that see light use. If that is your opening, the Orca OCL210 passage and OCL250 entrance locksets are medium-duty Grade 2, and the Dorma CL701 is a Grade 2 dummy lever for inactive leaves.
14) Can I standardize a whole building on the Marks 195 Series with different functions on different doors?
That is the usual way it gets specified. The 195 Series runs vestibule, passage, privacy, classroom, storeroom, institution, corridor, hospital privacy and classroom intruder functions, all on the same lock chassis, lever and rose. Every opening gets the same trim, the same 2-3/4 inch backset prep and the same 4-7/8 ASA strike cutout, and only the function changes. Spare parts and levers cross the whole building.
15) Why do lever locks break on abused doors, and does the Marks 195DA solve it?
Rigid lever locks fail because the whole force of somebody hanging on or kicking a locked lever goes straight into the retractor and spindle. The 195DA clutch disengages the outside lever when locked so it just spins, taking that torque out of the lock train, and the American and Crescent breakaway lever designs give way under extreme abuse rather than destroying the chassis. It is rated to 1,800 inch-pounds, over twice the ANSI/BHMA 1996 test value. If you are replacing locks on a school or public restroom door that keeps failing, this is the mechanism that addresses it.
16) Is there a lighter-duty lever lockset to use instead of the Marks USA 195DA on a low-traffic interior door?
The Orca Hardware OCL210 is a Grade 2 medium-duty passage/hall/closet cylindrical lockset, and the Dorma CL701 is a Grade 2 non-keyed passage/hall/closet lever lockset in the CL700 series. Both cover passage duty at Grade 2 rather than the Grade 1 rating the Marks USA 195DA carries, which is life tested over 6 million cycles and rated to 1,800 inch-pounds of torque. On an interior office or closet door that sees a few cycles a day, the Grade 2 chassis matches the traffic; on a vestibule or corridor door, the 195DA's cycle and torque numbers are the reason to stay with it.
17) Which cylindrical lock replaces the Marks USA 195DA when the opening needs keypad or credential access instead of mechanical keys?
The Marks USA 195DA is a mechanical cylindrical lockset. When the opening needs code or credential entry, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical entrance lock with a digital keypad, 100 user codes, IC/SFIC compatibility, and a 1-5/8 inch to 1-7/8 inch door thickness range that matches the 195DA's own 1-5/8 inch to 1-7/8 inch range. The Schlage NDEB is a Grade 1 heavy duty wireless cylindrical lock in the ENGAGE series using 2.4 GHz Bluetooth Low Energy for 1-5/8 inch to 2 inch doors, and the TownSteel XCE-2000 is a Grade 1 heavy duty electronic cylindrical lockset with a keypad for 1-3/4 inch to 2 inch doors.
18) For a classroom lockdown requirement, what cylindrical lockset covers that instead of the Marks USA 195DA?
The 195DA's own function keeps the latch retracted by the levers at all times, so it does not secure a classroom door on its own. The TownSteel FCE-4000 is an RFID electronic intruder classroom cylindrical lockset, Grade 1 heavy duty for 1-3/4 inch doors, and the TownSteel XCE-9000 is a Grade 1 heavy duty electronic classroom intruder cylindrical lockset with a keypad for 1-3/4 inch to 2 inch doors. The Schlage XE360M is a Grade 1 wireless tubular lock in classroom/storeroom function for 1-3/4 inch doors, using a smart mobile reader rather than a cylindrical chassis.
19) Is a keyless pushbutton knob lock a substitute for the Marks USA 195DA on an ADA opening?
The Lockey 2830 mechanical pushbutton keyless knob lock with auto-locking passage function and the Lockey 1600 heavy duty mechanical keyless knob lock with adjustable backset are knob-operated, both fitting doors 1-1/8 inch to 2 inch. The Marks USA 195DA is a lever lockset and is ADA compliant, with solid cast Zamac levers on a 1/2 inch return. Where the opening is required to be ADA compliant, a knob is a different operating device, so match the requirement before treating the Lockey units as interchangeable.
20) Which cylindrical lockset should I look at instead of the Marks USA 195DA for an access-controlled door that has to release on a signal from the panel?
The 195DA is offered in electrified functions at 100 percent duty cycle, 24V/AC with a bridge rectifier, 24V/DC at 0.21 Amps standard and 12V/DC optional, with an optional REX switch. If the specification calls for a purpose-built electric lock instead, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock with dual voltage 12/24VDC for doors 1-3/4 inch to 2 inch, and the SDC E75 Series is a battery-powered electronic cylindrical lockset with keypad access control for 1-3/4 inch to 2-1/8 inch doors. The 7200 takes its release from the panel wiring; the E75 runs on its own batteries and credentials.
21) Does the Stanley QCL150 entry lever cross to the Marks USA 195DA on strike and backset?
The Stanley Security QCL150 is a Grade 2 entrance lever from the QCL100 series, listed with a square 2-3/4 inch backset latch and a 4-7/8 inch by 1-1/4 inch ASA strike, less cylinder. The Marks USA 195DA is Grade 1 with a standard 2-3/4 inch backset and a #1135 strike with a 4-7/8 inch ASA curved lip, so the door prep lines up on backset and ASA strike height. The functions are not the same: the QCL150 is an entrance lever, while the 195DA is non-keyed with the latch retracted by the levers at all times.
22) Can a residential smart lever like the Kwikset 912TNL stand in for the Marks USA 195DA in a commercial building?
The Kwikset 912TNL ZW500 SmartCode electronic Tustin lever with Z-Wave technology is keyed one side and fits doors 1-3/8 inch to 2 inch. The Marks USA 195DA is a commercial lockset, ANSI/BHMA certified and UL Listed, Grade 1, and 3-hour fire rated. On a fire-rated commercial opening the fire rating and Grade 1 certification are the deciding specs, so confirm those against whatever product is being considered before swapping in a smart residential lever.
23) I need an electronic lock with an audit trail rather than the Marks USA 195DA - what covers that?
The Alarm Lock T3 DL3075 is an electronic cylindrical lock with audit trail and keypad access, Grade 1, from the DL3200 series. For a double-sided arrangement, the Alarm Lock DL5200 is a double-sided electronic cylindrical lock with 100 user capacity and battery operation, fitting doors 1-5/8 inch to 1-7/8 inch, the same door thickness range the Marks USA 195DA covers. The Marks USA 195DA is mechanical and records nothing; the DL3075 is the one to specify when the facility needs a log of who opened the door.
