Marks USA 195SB/26D – Frequently Asked Questions

1) Will the Marks 195SB latch into the strike that is already in my frame?
It depends what is in the frame now. The 195SB uses latch #1834 with a 1-1/8 x 2-1/4 inch front and a 9/16 inch throw, and it ships with the #1135 strike, a 4-7/8 inch ASA curved lip. If your frame is already prepped for a 4-7/8 ASA strike, it drops straight in. A frame cut for a small T-strike or a 2-3/4 inch full lip strike will need the prep changed or the new strike will not sit.
2) Can I put the Marks 195SB on a fire rated corridor door?
Yes. The 195SB is 3-hour fire rated and UL Listed, with a deadlocking latch, which is what a fire assembly needs so the latch cannot be shimmed and stays positively latched. It is also ADA compliant, so the lever meets the operable-hardware requirement on an accessible route.
3) What does ANSI function F75 mean on this Marks lockset, and is that the same as a classroom lock?
F75 is the passage function: the latch is retracted by the levers from either side at all times, with no locking. That is the right pick for a corridor, closet, or communicating door that only needs to stay latched, not secure. If you need the corridor side to lock by key while the inside always exits free, that is the classroom function and a different lock in the 195 Series, not F75.
4) What electronic Grade 1 classroom lock can I use in place of the mechanical Marks 195SB?
Several Grade 1 electronic cylindrical locks cover classroom openings. The TownSteel XCE-2000 is a heavy duty Grade 1 keypad cylindrical lockset in classroom function for 1-3/4 inch to 2 inch doors, and the XCE-9000 is the classroom intruder version over the same thickness range. The TownSteel FCE-2000 is a Grade 1 motorized RFID classroom lockset for 1-3/4 inch doors, and the Schlage XE360M is a Grade 1 wireless tubular lock in classroom/storeroom function for 1-3/4 inch doors. The Marks USA 195SB is a mechanical cylindrical lever with no credential reader or keypad.
5) What is the closest Grade 1 mechanical passage lever to the Marks USA 195SB?
The Cal-Royal CAL30 from the Calypso series is the nearest straight equivalent - it is a Grade 1 extra heavy duty cylindrical passage lockset with a door thickness range of 1-3/8 inch to 2 inch. The Marks USA 195SB is also Grade 1 with a passage/hall/closet function and a 2-3/4 inch backset. The difference is chassis design: the 195SB uses a stainless steel clutch that disengages the levers from the retractor, while the CAL30 is a conventional non-clutched Grade 1 chassis. The CAL30 also covers thinner 1-3/8 inch doors directly, where the 195SB uses a K1904 spacer for that thickness.
6) I need the door to lock, not just latch. What should I order instead of the Marks 195SB?
The Marks USA 195SB is a non-keyed lever with the latch retracted by the levers at all times, so it does not secure the opening. For a keyed opening, the Dorma C853 is a Grade 1 single cylinder entry lever covering 1-3/8 inch to 2-1/4 inch doors, and the Dorma C150 is a Grade 1 heavy-duty cylindrical lock in entry/office function for the same thickness range. The Orca OCL250 is a Grade 2 entrance lockset for lighter traffic.
7) For a restroom or bedroom door, what takes the place of the Marks 195SB?
Use a privacy function lever instead. The Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock for 1-3/8 inch to 2 inch doors, matching the 195SB's Grade 1 level, and the Orca OCL240 is a medium duty Grade 2 privacy lockset for lighter traffic. The Marks USA 195SB is a passage/hall/closet function, so it has no interior locking button and cannot serve a restroom or bedroom.
8) Why would I pick a clutched lever lockset over a standard commercial lever?
The clutch is what keeps the lever from drooping. On the 195SB a stainless steel clutch disengages the levers from the retractor when the lock is secured, so someone yanking on a locked lever spins it free instead of loading the internal mechanism. On a conventional lever the same abuse works the spring and the retractor until the lever sags. In a school corridor or a dorm, that is the difference between a lock that lasts and a service call every semester. Marks rates the 195 chassis past 3.6 million cycles, three times the BHMA Grade 1 requirement.
9) Does the Marks 195SB come keyed, and what keyway is it?
The 195SB is set up for the Marks C keyway with a 6-pin cylinder, but it is not supplied keyed, so keying is specified separately. If your building already runs a Marks C master system, this drops into that system. If you are on Schlage C or Kwikset, you are either rekeying to Marks C or you are picking a different lock.
10) I need a Grade 1 lever lock but my doors are thicker than 1-7/8 inches. What else is there?
The 195SB chassis tops out at 1-7/8 inches. For thicker leaves, the Dorma C150 Grade 1 cylindrical lock covers 1-3/8 to 2-1/4 inches in an entry/office function, and the Dorma C853 Grade 1 entry lever covers the same 1-3/8 to 2-1/4 inch range. Cal-Royal's Calypso CAL30 passage lock handles 1-3/8 to 2 inches if the opening does not need to lock.
11) Which alternatives to the Marks 195SB fit the same 1-5/8 inch to 1-7/8 inch door thickness?
The Marks USA 195SB covers doors 1-5/8 inch to 1-7/8 inch thick. The Alarm Lock Trilogy T2 DL2700 Grade 1 standalone electronic cylindrical entrance lock lists the identical 1-5/8 inch to 1-7/8 inch range, as do the Alarm Lock Trilogy 4100 in privacy function and the DL5200 double-sided electronic lock. The Schlage NDEB Grade 1 ENGAGE wireless cylindrical lock covers 1-5/8 inch to 2 inch. All four are electronic access control rather than mechanical lever trim.
12) Is there a lighter duty passage lever I can use instead of the Marks 195SB on interior office doors?
Yes. The Orca Hardware OCL210 is a medium duty Grade 2 passage cylindrical lockset, and the Dorma CL701 is a Grade 2 non-keyed lever with a passage/hall/closet function. Both carry a lower ANSI/BHMA grade than the Marks USA 195SB, which is Grade 1 and rated commercial. For low-traffic interior doors where Grade 1 is not called out on the drawing, either Grade 2 lever covers the same latch-always-retracted operation.
13) Is a dummy lever the same thing as the Marks 195SB passage lever?
No. The Marks USA 195SB has a working latch - a deadlocking latch with a 9/16 inch throw and a 1-1/8 inch by 2-1/4 inch front - retracted by the levers. A dummy trim such as the Dorma C501 Grade 2 single dummy or the Orca OCL2170 Grade 2 half dummy is surface trim with no latch and no moving chassis, used on inactive leaves and pull-side applications only. Do not substitute one for the other on a door that needs to latch.
14) What keyless option covers the same door thickness range as the Marks 195SB without wiring?
The Marks USA 195SB fits doors 1-5/8 inch to 1-7/8 inch thick. Among battery-free keyless choices, the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function that covers 1-1/8 inch to 2 inch doors, and the Lockey 1600 heavy duty mechanical keyless knob lock with adjustable backset spans the same 1-1/8 inch to 2 inch range. Both are pushbutton knob locks rather than lever trim, so verify ADA lever requirements for the opening - the 195SB is ADA compliant lever hardware.
15) What is the mounting on the 195SB rose, and will it cover the old holes?
Roses are 3-7/16 inches in diameter, spring loaded, and thru-bolted with two #10 thru-bolts. Thru-bolting is what you want on a high-traffic door because the two sides clamp to each other rather than relying on screws into the door. The 3-7/16 inch rose will hide a standard 2-1/8 inch bore and typical trim scarring around it.
16) What finish does the Marks 195SB lever lockset come in?
Satin chrome, US26D. That is the standard institutional finish, so it will sit alongside most existing school, hospital, and office door hardware without looking mismatched. If the rest of your openings are US26D closers, hinges, and exit devices, this matches.
