Key Features

Exceeds BHMA Grade 1 by 300%: Tested to over 3.6 million cycles, far surpassing standard Grade 1 requirements for exceptional longevity in high-traffic applications.
Unique Clutch Mechanism: Stainless steel clutch disengages levers from the retractor when locked, allowing levers to swing freely without resistance — eliminating lever droop and dramatically reducing internal wear.
Cast Bronze Roller Bearings: Cylindrical lock chassis constructed with cast retractors on bronze roller bearings for smooth, durable operation over millions of cycles.
Dual Backset Compatibility: Accommodates both 2-3/8" and 2-3/4" backsets for flexible installation across a wide range of door preparations.
Latch #1834 Specifications: Front measures 1-1/8" x 2-1/4" with a 9/16" throw and stainless steel nose for reliable latching performance.
Solid Cast Zamac Levers: Levers feature solid cast zamac construction with 1/2" return, and roses are thru-bolted at 3-7/16" diameter with spring-loaded 2-#10 thru-bolts for secure mounting.
3-Hour Fire Rated: Certified for 3-hour fire-rated door assemblies, meeting critical life-safety code requirements.
Marks Lifetime Mechanical Warranty: Backed by Marks USA's Lifetime Mechanical Warranty for long-term confidence and lower total cost of ownership.
Wide Function Availability: Available in numerous functions including Classroom (S), Classroom Intruder (DB), Storeroom (F), Entry (AB), Hotel (H), Institution (DW), Electrically Locked (FEL), Electrically Unlocked (FEU), and many more.

Marks USA 195RS/26D – Frequently Asked Questions

1) What backset does the Marks 195RS come with, and can I use it on a door bored for 2-3/8 inch?

It ships with a 2-3/4 inch backset latch, which is the usual commercial prep. The 195 Series chassis also accommodates a 2-3/8 inch backset, so both of the standard bored-door preps are covered. Check which one your door is bored for before you order, because the latch that comes in the box is the 2-3/4.

2) Does the Marks 195RS come with a cylinder, or do I have to supply the core?

Supplied less core. The 195RS is built for a small format interchangeable core (SFIC), and you provide the core yourself, keyed into whatever system the building already runs. That is the point of the RS designation: a locksmith or facility keying a whole site drops their own SFIC cores in and keeps every door on one system.

3) Will the Marks 195RS latch into the strike that is already in my frame?

It comes with an ANSI #1135 4-7/8 inch ASA curved lip strike, so if your frame is already prepped for a standard 4-7/8 inch ASA strike, it drops straight in. The latch is the #1834 with a 9/16 inch throw and a front measuring 1-1/8 x 2-1/4 inches. That 9/16 throw is the number to check against your existing latch mortise depth and strike pocket. The latch is deadlocking, so the anti-friction plunger has to seat against the strike lip to hold.

4) I need a classroom intruder function that locks from inside the room. Does the Marks 195 Series do that?

The 195 Series is offered in a classroom intruder function, designated DB, alongside standard Classroom (S), Storeroom (F), Entry (AB), Hotel (H) and Institution (DW). The 195RS as configured is the standard Classroom function. If your district requires the teacher to lock the door from inside the room without stepping into the corridor, specify the DB intruder function when you order rather than the S. Electronic alternatives exist too: the TownSteel FCE-4000 Series is an RFID electronic intruder classroom cylindrical lockset, and the XCE-9000 Series is a keypad classroom intruder lockset.

5) Does the Marks 195RS work if my doors are thinner or thicker than the standard range?

Below the range, a 1-3/8 inch door is handled with the K1904 spacer. Above 1-7/8 inches, the 195RS is out of its range and you want a different chassis. Among Grade 1 cylindrical locks, the Dorma C150 covers 1-3/8 to 2-1/4 inches and the Dorma C853 entry lever covers the same 1-3/8 to 2-1/4 inch span. For a Grade 1 wireless option on thicker doors, the Schlage NDEB ENGAGE Series goes 1-5/8 to 2 inches.

6) What is the closest mechanical classroom cylindrical lock to the Marks USA 195RS if I need a keypad instead of a key?

The TownSteel XCE-2000 Series is an electronic cylindrical lockset with a keypad in a Classroom function, Grade 1, heavy duty, fitting doors 1-3/4 inch to 2 inch. The Marks USA 195RS is a mechanical Grade 1 classroom lever lockset prepped for a small format interchangeable core and supplied less core, so credentials are carried on a key rather than entered on a keypad. Choose the XCE-2000 when the opening needs code-based entry and the 195RS when it stays on the facility keyway.

7) Will a Kwikset 912TNL or Lockey E985 work where the Marks USA 195RS is specified?

The Kwikset 912TNL ZW500 SmartCode is an electronic Tustin lever with Z-Wave, keyed one side, for doors 1-3/8 inch to 2 inch. The Lockey E985 and E995 are electronic keypad lever locks with remote control, fitting doors 1-3/8 inch to 1-3/4 inch. The Marks USA 195RS is a commercial Grade 1, UL Listed, ADA compliant classroom lockset, so where the drawing calls out a Grade 1 commercial classroom lever, those three do not carry that designation.

8) What does the clutch in the Marks 195RS actually do for me on a high traffic school door?

When the lock is secured, a stainless steel clutch disconnects the lever from the retractor, so anyone yanking on the outside lever spins it freely instead of loading the internal parts. Two practical results: the lever does not droop over time, and the wear that normally kills a classroom lock never reaches the chassis. Marks rates the 195 Series past 3.6 million cycles, which is well beyond what BHMA Grade 1 asks for. On a corridor or K-12 classroom door that gets abused daily, that is the difference between a lock you replace and one you forget about.

9) Is a mechanical classroom lockset like the Marks 195RS the right choice, or should I go electronic?

A keyed mechanical classroom lock is the right call when you want no batteries, no programming, and one key system across the building. The 195RS is that: cylindrical, Grade 1, SFIC, locked and unlocked with the key. If instead you need codes per user, an audit trail, or credentials, that is a different product. The TownSteel FCE-2000 Series is a Grade 1 standalone motorized cylindrical classroom lockset with RFID, and the TownSteel XCE-2000 Series is a Grade 1 classroom lockset with a keypad. Both of those are 1-3/4 inch door products, so they are narrower on thickness than the 195RS.

10) Can I mount the Marks 195RS on a hollow metal door, and does it need thru-bolting?

The roses are thru-bolted with spring loaded 2-#10 thru-bolts at a 3-7/16 inch rose diameter, which is what you want on a hollow metal or wood door in a high abuse space. Thru-bolted mounting means the two sides clamp through the door rather than screwing into the skin, so the trim does not work loose. Nothing else is needed for mounting on a door already bored for a standard cylindrical lock at 1-5/8 to 1-7/8 inches thick.

11) Will an SFIC core from my existing keyway drop into the Marks 195RS?

The 195RS is prepped for small format interchangeable core and ships without one, so any small format core your system already uses goes in. That is how you bring a new classroom door onto the same master key system as the rest of the building without rekeying anything else. Several other cylindrical locks we carry are also IC/SFIC compatible, including the Alarm Lock Trilogy T2 DL2700, if you want a standalone electronic door on the same core family.

12) Is the Alarm Lock Trilogy DL2700 a substitute for the Marks USA 195RS on a school corridor door?

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, fitting doors 1-5/8 inch to 1-7/8 inch. That door thickness range is the same range the Marks USA 195RS covers, and both accept a small format interchangeable core, so the prep carries over. The difference is function and credential: the DL2700 is an entrance-function lock with codes, while the 195RS is a mechanical classroom-function lever.

13) What Grade 1 cylindrical lever should I order instead of the Marks USA 195RS for an office door that does not need classroom function?

The Dorma C150 is a Grade 1 heavy-duty cylindrical lock in an Entry/Office function from the C100 Series, fitting doors 1-3/8 inch to 2-1/4 inch. The Dorma C853 is a Grade 1 entrance-function keyed lever with a single cylinder, also 1-3/8 inch to 2-1/4 inch. Both keep the Grade 1 rating of the Marks USA 195RS while giving an entry or office function rather than classroom.

14) Can I use an Orca OCL250 or Cal-Royal CAL30 in place of the Marks USA 195RS?

Not as a like-for-like. The Orca Hardware OCL250 is a Grade 2 medium duty entrance cylindrical lockset and the Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lock in the Calypso Series for doors 1-3/8 inch to 2 inch. Neither is a classroom function, and the OCL250 sits at Grade 2 rather than the Grade 1 rating the Marks USA 195RS carries. Use them where the opening genuinely calls for entrance or passage function, not as a swap for a keyed classroom door.

15) Which cylindrical lock is comparable to the Marks USA 195RS if I need wireless access control on the door?

The Schlage NDEB is a Grade 1 ENGAGE Series wireless cylindrical lock using 2.4 GHz Bluetooth Low Energy, available in Storeroom, Office, Privacy, and Apartment functions, heavy duty, for doors 1-5/8 inch to 2 inch. The TownSteel FCE-2000 Series is a Grade 1 standalone motorized cylindrical lockset with RFID in a Classroom function on a 1-3/4 inch door. The Marks USA 195RS is the mechanical equivalent for the same chassis type, keyed through a small format interchangeable core.

16) What is the difference between the Marks USA 195RS and the Schlage XE360M for a classroom door?

The Schlage XE360M is a Grade 1 wireless tubular lock with an offline push button function and a smart mobile reader, in a Classroom/Storeroom function for a 1-3/4 inch door. The Marks USA 195RS is a cylindrical lock, a different chassis type from a tubular lock, in a classroom function with a 2-3/4 inch backset and a deadlocking latch. If the door is already prepped for a cylindrical chassis, the 195RS drops into that prep.

17) I need a simpler non-keyed lever on the same door prep as the Marks USA 195RS - what are the options?

The Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset, and the Orca Hardware OCL240 is a medium duty privacy cylindrical lockset. The Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock for doors 1-3/8 inch to 2 inch. All three are non-keyed, so they need no cylinder at all, while the Marks USA 195RS is supplied less core and requires a small format interchangeable core to be ordered separately.

18) Is the Dorma C501 or CL701 an alternative to the Marks USA 195RS for a door that only needs a lever on one side?

Those are dummy trim, not working locksets. The Dorma C501 is a Grade 2 single dummy keyless lever from the C500 Series for doors 1-3/8 inch to 1-3/4 inch, the Dorma CL701 is a Grade 2 single dummy non-keyed cylinder lever, and the Orca Hardware OCL2170 is a Grade 2 half dummy lever, medium duty. None of them retract a latch. The Marks USA 195RS is a functioning classroom lockset with a deadlocking latch and a 9/16 inch throw, so a dummy lever is only correct on an inactive leaf.

19) Which lock takes a small format interchangeable core like the Marks USA 195RS does?

The Alarm Lock Trilogy T2 DL2700 is IC/SFIC compatible and the BEST 9KZ EZ Series electronic keypad cylindrical lock includes a key override function. The Marks USA 195RS is prepped for a small format interchangeable core and ships less core, so a facility already stocking SFIC cores can key all three into the same system rather than introducing a second keyway.

20) What takes the place of the Marks USA 195RS on an opening that needs to unlock from an access control panel?

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, so it is driven by the panel rather than by a key. The SDC E75 Series is a battery-powered electronic cylindrical lockset with keypad access control for doors 1-3/4 inch to 2-1/8 inch, which needs no wiring to the door. The Marks USA 195RS is the mechanical option for the same cylindrical prep.

21) How does the Stanley QCL150 compare to the Marks USA 195RS on backset and strike?

The Stanley Security QCL150 is a Grade 2 entry lever in the QCL100 Series with a Sierra bent lever on a rose, less cylinder, a square 2-3/4 inch backset latch, and a 4-7/8 inch by 1-1/4 inch ASA strike. The Marks USA 195RS also ships with a 2-3/4 inch backset and a 4-7/8 inch ASA curved lip strike, so the door and frame prep line up. The functional split is grade and function: Grade 2 entry on the QCL150 against Grade 1 classroom on the 195RS.

22) Does the Schlage CO-100 cover the same door as the Marks USA 195RS?

The Schlage CO-100 is a Grade 1 heavy duty standalone electronic cylindrical lock with a keypad and cylinder options, but in a Privacy function on a 1-3/4 inch door. Privacy function locks from the inside for a restroom or similar, which is not the classroom control the Marks USA 195RS provides, where the cylinder governs the outside lever. Match the function to the opening before matching the grade.

23) Can a Lockey mechanical keyless lock replace the Marks USA 195RS?

The Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset for doors 1-1/8 inch to 2 inch, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function over the same thickness range. Both are knob locks operated by a pushbutton code, so there is no key and no lever. The Marks USA 195RS is an ADA compliant lever lockset, which matters on openings where lever operation is required.

24) What finish does the Marks USA 195RS classroom lever come in?

US3 bright brass. That is the single finish offered on the 195RS classroom SFIC configuration, so if you are matching a building already standardized on satin chrome or oil rubbed bronze, this particular part will not blend in. The lever itself is solid cast zamac with a 1/2 inch return, on a thru-bolted rose 3-7/16 inches in diameter.

25) Is the Marks 195RS overkill for an office or storage door, and what is a lighter option?

For a low traffic office or closet, a Grade 1 clutched classroom lock is more lock than the opening needs. Orca Hardware's OCL210 passage and OCL250 entrance locksets are medium duty Grade 2 cylindrical, and the Dorma CL701 is a Grade 2 non-keyed lever. Where the door sees real cycle counts, a corridor, a classroom, a public restroom, stay with Grade 1. The 195RS is specified commercial and is built past 3.6 million cycles.

26) Does handing matter when ordering the Marks 195RS lever lock?

Cylindrical locks in the 195 Series are non-handed in the sense that the chassis takes either swing, but the latch has to be oriented to the door. Confirm your bore is a standard 2-1/8 inch cross bore prep at 2-3/4 inch backset and the latch front matches the existing 1-1/8 x 2-1/4 inch mortise in the door edge. If your door edge is prepped for a drive-in latch instead of a faceplate, that is the detail that will stop the install.
