Marks USA 195DC Communicating Clutched Lever Lockset — Grade 1, Marks C Keyway, UL Listed 3-Hour Fire Rated

The Marks USA 195DC is a Grade 1 Communicating Clutched Lever Lockset from the 195 Series, engineered for demanding commercial applications where durability and security are paramount. Featuring "The Clutch" mechanism, the outside lever disengages when locked — turning freely without actuating the latch — dramatically reducing torque stress compared to rigid-lever locksets. The lockset withstands torque of 1,800 inch-pounds (over twice the ANSI/BHMA 1996 test value) and has been life tested to over 6 million cycles. Supplied with a 6-pin cylinder in Marks C keyway with 2 nickel-silver keys, it supports door thicknesses of 1-5/8" to 1-7/8" (use K1704 spacer for 1-3/8" doors) and is UL Listed with a 3-hour fire rating.

Key Features

  • Clutch Mechanism — "The Clutch": When locked, the outside lever disengages and turns freely without opening the latch, reducing torque on the lever and preventing the failures common to rigid-lever locksets.
  • Exceptional Torque Resistance: Withstands 1,800 inch-pounds of torque — over twice the ANSI/BHMA (1996) test value — for superior resistance to forced entry and abuse.
  • Heavy-Duty Life Cycle Rating: Life tested to over 6 million cycles and fully operational after testing, ensuring long-term reliability in high-traffic commercial environments.
  • Breakaway Handle Design: American and Crescent design breakaway handles protect against excessive abuse and lever damage.
  • Backset & Door Compatibility: Standard 2-3/4" backset; optional 2-3/8", 3-3/4", and 5" backsets available. Fits door thicknesses of 1-5/8" to 1-7/8" (K1704 spacer required for 1-3/8" doors).
  • Latch & Strike Specifications: Latch #1834 with 1-1/8" x 2-1/4" front, 9/16" throw, and stainless steel nose. Strike #1135, 4-7/8" ASA curved lip.
  • Electrified Operation: 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 (not standard).
  • Cast Stainless Steel Retractor: Retractor is cast stainless steel with bronze roller bearings for ultra-high strength, smooth operation, and long service life.
  • Solid Cast Zamac Levers: Levers are solid cast Zamac with 1/2" return. Rose is thru-bolted, 3-7/16" diameter, spring loaded with 2 #10 thru-bolts.
  • Vibration-Proof Thru-Bolt Mounting: Thru-bolting with #10 epoxy-coated bolts ensures vibration-proof mounting with only two thru-bolts required for easy installation.
  • Versatile Function Availability: Available in Passage, Privacy, Patio, Communicating, Entry, Exit, Classroom, Storeroom, Institution, Vestibule, Corridor, Store Door, Hospital/Privacy, Service Station Lock, Classroom Intruder, Dummy Trim, Communicating Passage, Communicating Storeroom, and Communicating Classroom functions.

Marks USA MAR195DC/26D – Frequently Asked Questions

1) Will the Marks USA 195DC fit a 1-3/8 inch door?
Not as supplied. The 195DC covers door thicknesses of 1-5/8 inch to 1-7/8 inch, and a 1-3/8 inch door needs the K1704 spacer added to the order. If you are hanging hardware on a mix of older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors, plan on the spacer for the thin ones. A wider out-of-the-box range is available from other brands we carry, such as the Cal-Royal CAL30 passage lever at 1-3/8 inch to 2 inch.
2) What backset does the Marks 195 Series lever lock come with, and can I get it for a wide stile or narrow prep?
Standard is a 2-3/4 inch backset, which is the usual commercial bored prep. Optional 2-3/8 inch, 3-3/4 inch and 5 inch backsets are available, so the 195 will cover both the common residential-style 2-3/8 prep and wide-stile aluminum or specialty doors that need a 3-3/4 or 5 inch reach.
3) Will the Marks 195DC latch into the strike and latch prep already in my frame?
The 195DC uses latch #1834 with a 1-1/8 x 2-1/4 inch front, a 9/16 inch deadlocking throw and a stainless steel nose, and ships with the #1135 strike, 4-7/8 inch ASA curved lip. So if your frame already has the standard 4-7/8 inch ASA strike cutout and a 1-1/8 x 2-1/4 inch latch face mortise, it drops in. Frames prepped for a smaller T-strike or a 1-1/8 x 2-3/4 inch front will need rework.
4) What does the clutch mechanism on the Marks 195 actually do, and why would I pay for it?
When the lock is secured, the outside lever disengages and spins freely instead of fighting the latch. That is the failure mode on rigid-lever cylindrical locks: someone hangs on a locked lever and shears the spindle or sags the lever. The 195 takes 1,800 inch-pounds of torque, more than twice the ANSI/BHMA 1996 test value, and has been life tested past 6 million cycles while still operating. In a school corridor or a hospital wing where levers get abused daily, that is the reason to specify it over a standard Grade 1 lever.
5) What voltage does the electrified Marks 195 run on, and can it stay energized continuously?
The electrified version is 100 percent duty cycle, so it can be held energized indefinitely without overheating. Standard is 24V/DC at 0.21 amps; 24V/AC is supplied with a bridge rectifier, and 12V/DC is an option. A Request to Exit switch is available but is not standard: single pole double throw, 3 amp, 125 AC, wired normally open or normally closed. Specify the REX and its wiring state on the order if your access control panel needs the egress signal.
6) What is a comparable Grade 1 cylindrical passage lever to the Marks USA 195DC?
The Cal-Royal CAL30 from the Calypso series is a Grade 1 extra heavy duty passage cylindrical lockset and covers doors 1-3/8 inch to 2 inch thick. The Marks USA 195DC is also Grade 1 with a passage/hall/closet function and ANSI F75, and it fits 1-5/8 inch to 1-7/8 inch doors with a K1704 spacer used for 1-3/8 inch doors. The 195DC adds the Marks clutch mechanism, where the outside lever turns freely when locked, and a UL Listed 3-hour fire rating.
7) If I need a keypad instead of a keyed cylinder, what replaces the Marks USA 195DC?
For standalone keypad entry on a similar cylindrical prep, 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, and it fits 1-5/8 inch to 1-7/8 inch doors, the same range the Marks USA 195DC covers. The 195DC is a mechanical lockset supplied with a 6-pin Marks C keyway cylinder and two nickel-silver keys.
8) For a classroom intruder application, is the Marks USA 195DC or an electronic classroom lock the better fit?
The Marks USA 195DC family includes a Classroom Intruder function mechanically, which locks from inside without opening the door and needs no power or batteries. If you want audit capability and credential management, 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, and the TownSteel FCE-4000 is an RFID electronic intruder classroom lockset for 1-3/4 inch doors.
9) Can the SDC Electra 7200 replace the electrified Marks USA 195DC?
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. The electrified Marks USA 195DC runs 24V/DC at 0.21 amps with 100 percent duty cycle, 12V/DC optional, and 24V/AC supplied with a bridge rectifier, and it fits 1-5/8 inch to 1-7/8 inch doors. Check your door thickness first, since the two ranges only overlap at 1-3/4 inch.
10) Does the Marks 195DC come with a cylinder and keys, or do I key it myself?
It is supplied with a 6-pin cylinder in the Marks C keyway plus two nickel-silver keys. If your building is already standardized on a different keyway or on an SFIC core, that matters: the 195DC as supplied is a Marks C proprietary keyway, not an interchangeable-core lock. For an IC/SFIC building standard, an Alarm Lock Trilogy T2 DL2700 is IC/SFIC compatible.
11) What is a communicating function lockset used for?
Communicating functions are for openings between two spaces that both need control, such as adjoining patient rooms, hotel connecting doors, or office suites, rather than a single corridor entrance. The 195 family is available in Communicating, Communicating Passage, Communicating Storeroom and Communicating Classroom, along with Passage, Privacy, Patio, Entry, Exit, Classroom, Storeroom, Institution, Vestibule, Corridor, Store Door, Hospital/Privacy, Service Station, Classroom Intruder and Dummy Trim. Confirm which function code you need before ordering, since the function is built into the chassis and not field-changeable.
12) Is there a mechanical alternative if I do not need the Marks C keyway or the clutch?
For a plain Grade 1 mechanical lever on a bored prep, the Cal-Royal Calypso CAL30 covers passage and the CAL20 covers privacy, both Grade 1 and both rated 1-3/8 inch to 2 inch doors, which is a wider thickness range than the 195 handles without a spacer. The Dorma C150 is a Grade 1 entry/office cylindrical lock for 1-3/8 inch to 2-1/4 inch doors. None of those carry the 195's clutch mechanism or its 1,800 inch-pound torque figure, so on abuse-prone openings the Marks is still the specification.
13) I need keypad or credential access on the same bored prep. What replaces the Marks 195?
Standalone and networked electronic cylindrical locks use the same bored door prep. The Alarm Lock Trilogy T2 DL2700 is Grade 1 with a digital keypad, 100 user codes, and fits 1-5/8 inch to 1-7/8 inch doors, the same thickness window as the 195. The Schlage NDEB ENGAGE is Grade 1 wireless Bluetooth for 1-5/8 inch to 2 inch doors, and the TownSteel XCE-9000 is a Grade 1 classroom intruder keypad lockset for 1-3/4 inch to 2 inch doors. Note the trade-off: the 195DC's electrified version needs a power feed and a panel, while these run standalone.
14) What ANSI function is the non-keyed Marks 195 passage version?
F75, the passage function: the latch is retracted by the levers from both sides at all times, with no keying and no locking. Use it on closets, corridors and hall doors where you want latching without any securing. Anywhere that needs to lock, order a keyed or privacy function from the 195 family instead.
15) Is there a lower-cost medium duty alternative to the Marks USA 195DC for light traffic doors?
The Orca Hardware OCL210 passage cylindrical lockset is a Grade 2 medium duty lever and suits interior openings that do not see institutional traffic. The Marks USA 195DC is Grade 1 commercial with a cast stainless steel retractor on bronze roller bearings and life testing past 6 million cycles, so it is the choice where the door is cycled hard all day.
16) Does the Schlage NDEB do the same job as the Marks USA 195DC?
They solve different problems. The Schlage NDEB is a Grade 1 heavy duty ENGAGE Series wireless cylindrical lock with 2.4 GHz Bluetooth Low Energy, mobile enabled, offered in storeroom, office, privacy and apartment functions, and it fits 1-5/8 inch to 2 inch doors. The Marks USA 195DC is a mechanical Grade 1 clutched lever lockset with an optional 24V electrified version at 0.21 amps and 100 percent duty cycle, so it ties into a hard-wired access control system rather than a credential-based wireless one.
17) What is the difference between the Marks USA 195DC and a dummy lever like the Dorma C501?
The Dorma C501 is a single dummy trim keyless lever lockset, Grade 2, for doors 1-3/8 inch to 1-3/4 inch; it has no latch and simply provides a pull. The Marks USA 195DC carries a working #1834 deadlocking latch with a 1-1/8 inch by 2-1/4 inch front and 9/16 inch throw, so it actually secures and latches the door. If you only need matching trim on an inactive leaf, a dummy is the right part.
18) If I only need privacy on a restroom door, what is an alternative to the Marks USA 195DC?
The Marks USA 195 Series is available in Privacy and Hospital/Privacy functions, so you can stay in the same series and match trim across the building. If you are pricing other Grade 1 privacy levers, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock covering 1-3/8 inch to 2 inch doors; the Orca Hardware OCL240 is a Grade 2 medium duty privacy lockset for lighter traffic.
19) Is the Stanley QCL150 an equivalent to the Marks USA 195DC entry function?
Not on grade. The Stanley Security QCL150 entry lever from the QCL100 Series is Grade 2, supplied less cylinder with a square 2-3/4 inch backset latch and a 4-7/8 inch by 1-1/4 inch ASA strike. The Marks USA 195DC is Grade 1 with the same standard 2-3/4 inch backset and a #1135 4-7/8 inch ASA curved lip strike, so the door prep lines up but the duty rating does not.
20) I need battery-powered keyless entry but the Marks USA 195DC is mechanical. What are my options?
For keyless without wiring, the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function that fits 1-1/8 inch to 2 inch doors and needs no power at all. For battery electronics, 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 Marks USA 195DC uses a 6-pin Marks C keyway cylinder and is keyed rather than keyless.
21) What finishes does the Marks 195DC lever come in?
Three: US3 bright brass, US26D satin chrome, and US10B oil-rubbed dark bronze. For a property manager matching existing openings, US26D is the usual commercial institutional match and US10B the darker architectural one. The levers themselves are solid cast Zamac with a 1/2 inch return, on a thru-bolted spring-loaded rose 3-7/16 inches in diameter.
22) How is the Marks 195 mounted, and will it loosen on a high-traffic door?
Mounting is thru-bolted with two #10 epoxy-coated bolts through a spring-loaded rose, which is what keeps it from working loose under vibration. Only two thru-bolts are needed, so installation is quick. Inside, the retractor is cast stainless steel running on bronze roller bearings rather than a stamped part.
23) Do the Marks 195 levers break if someone really abuses them?
By design. The 195 uses breakaway handle construction in both American and Crescent lever designs, so excessive force sacrifices the handle rather than destroying the chassis inside the door. Combined with the clutch, which frees the outside lever when the lock is secured, that keeps the repair to a lever swap instead of pulling and replacing the whole lockset.
