Marks USA 195S-26D – Frequently Asked Questions

1) Will the Marks USA 195S classroom lever work on a door prepped with a 2-3/8 inch backset?
No. The 195S is built on a 2-3/4 inch backset, which is the standard commercial bore location. If the existing door is bored at 2-3/8 inches, the cross-bore centerline won't line up and you'd have to re-prep the door or pick a lock offered with a 2-3/8 backset. Check the existing door before ordering: measure from the door edge to the center of the knob hole.
2) Will the Marks 195S latch into the strike already in my frame?
It depends what's in the frame now. The 195S latch has a 9/16 inch throw and comes with an ANSI strike measuring 1-1/4 by 4-7/8 inches with a 1-1/4 inch lip and square corners. If your frame is already prepped for a full ANSI/ASA strike of that size with square corners, the supplied strike drops straight in. Frames cut for a smaller T-strike, or for a radius-corner ANSI strike, will need the cutout modified or a radius strike substituted. The 9/16 inch throw is short, so the strike lip and frame reveal have to be right for the latch to seat and deadlock.
3) What does classroom function F84 actually do when the door is locked?
On the 195S, the outside lever is locked and unlocked by a key in the outside lever itself. Once locked, the outside lever stays rigid and you need the key to get in. The inside lever is always free, so anyone inside can walk out at any time without a key, thumbturn, or any other step. That's the difference between classroom function and a storeroom lock: with F84 a teacher or staff member with the key controls whether the corridor side is locked, and it stays that way until the key changes it. Note the key is on the corridor side, so locking down means stepping into the hallway.
4) Can I get a batch of Marks 195S classroom locks keyed alike across a building?
Yes. Keying is selected when you order: keyed different, keyed alike, or supplied less core if you're building on your own interchangeable core system. Keyed alike gives one key that opens every 195S in the group, which is the usual choice when the same staff cover a wing. Keyed different gives each door its own key. Ordering less core lets a locksmith drop in cores on the facility's existing keyway and master key system rather than starting a second one.
5) Should I use a mechanical classroom lock like the Marks 195S or go electronic for classroom lockdown?
The 195S is mechanical: locking or unlocking the corridor side takes a key at the door, with no batteries, wiring, or programming to maintain. That's the low-maintenance choice and it never fails to a dead battery. If the requirement is lockdown from inside the room, credentials instead of keys, or an audit trail of who entered, an electronic classroom lockset is the answer instead. The TownSteel FCE-4000 Series is a Grade 1 RFID electronic intruder classroom lockset, and the TownSteel XCE-9000 Series is a keypad classroom intruder lockset, both heavy duty. Schlage's XE360M is a Grade 1 wireless classroom/storeroom lock with a mobile reader.
6) I need an audit trail of who entered the classroom. Which lock does that instead of the Marks USA 195S?
The Alarm Lock T3 DL3075 is a Grade 1 electronic cylindrical lock with audit trail and keypad access from the DL3200 Series. The Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with a digital keypad, 100 user codes, and IC/SFIC compatibility, for doors 1-5/8 inch to 1-7/8 inch thick. The Marks USA 195S is a mechanical Grade 1 classroom lockset keyed with KD, KA, or less-core options and records nothing about who used it.
7) Can I put the Marks USA 195S on a credential-based access control system, or do I need a different lock?
A credential-based opening calls for a different lockset. The Schlage NDEB is a Grade 1 heavy duty ENGAGE Series cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader for doors 1-5/8 inch to 2 inch thick, and the TownSteel FCE-2000 is a Grade 1 heavy duty standalone motorized cylindrical lockset with RFID on a classroom function for 1-3/4 inch doors. The Marks USA 195S is a mechanical Grade 1 cylindrical lockset operated by key at the outside lever.
8) We use small format interchangeable cores. Which cylindrical locks work with SFIC alongside the Marks USA 195S?
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 195S is ordered with a keying selection of keyed different, keyed alike, or none for less core, so the less-core option leaves the lock ready for a core supplied on your own system.
9) What door prep does the Marks USA 195S need for the latch face?
The latch front on the 195S measures 1-1/8 by 2-1/4 inches, which is the common cylindrical lock face size, so it mortises into a standard edge prep. Pair that with the 2-3/4 inch backset for the cross bore. If you are replacing an older cylindrical lock and the existing edge mortise is that size, the front covers it.
10) Is the Marks USA 195S lever ADA compliant for a school or public building?
Yes, the 195S uses an American lever design that is ADA compliant, so it operates without tight grasping, pinching, or wrist twisting. It is also ANSI/BHMA Grade 1 and UL Listed. For accessible openings this is the reason to spec a lever rather than a knob.
11) Is a Grade 1 cylindrical lock overkill for a classroom door, or does it earn the upgrade?
On a classroom door it earns it. Grade 1 is the highest ANSI/BHMA commercial rating, and the 195S is tested past 3.6 million cycles, more than triple the Grade 1 requirement. A classroom door on a bell schedule gets cycled hundreds of times a day, and the stainless steel clutch plus bronze bearings are there specifically to stop lever droop, which is the usual failure on high-traffic levers. For a low-traffic office or storage door a Grade 2 lockset such as the Orca OCL250 entrance lockset covers the job at a medium duty level.
12) I need a Marks 195S but for a restroom and an unlocked corridor door on the same job. What do I order for those?
The 195S is classroom function only, keyed on the outside with a free inside lever, so it's wrong for both. For a restroom you want a privacy function: the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock. For a door that just needs to latch with no locking at all, the Cal-Royal CAL30 is the Grade 1 passage version of the same Calypso Series. Both of those Cal-Royal locks are listed for 1-3/8 to 2 inch doors. For a keyed office or entrance door, the Dorma C853 is a Grade 1 single cylinder entry lever.
13) Does the Marks 195S come with the strike, or do I need to order one separately?
The strike is included. Each 195S ships with a full ANSI strike, 1-1/4 by 4-7/8 inches, 1-1/4 inch lip, square corner. What is not included is the cylinder if you order the less-core option, so on an interchangeable core job budget for cores separately. Keyed different and keyed alike orders come keyed and ready to hang.
14) Can I standardize a whole facility on the Marks USA 195S Survivor Series?
For classroom-function openings, yes, and that's what it's built for. Every 195S shares the same 2-3/4 inch backset, 1-1/8 by 2-1/4 inch front, and 1-1/4 by 4-7/8 inch ANSI strike, so one door prep detail covers every opening and one spare latch fits any of them. Order the whole group keyed alike, or less core to bring them onto an existing master key system, and pick a single finish code. Openings that need privacy, passage, or entrance function will need a different lock, so the standard applies to the classroom doors rather than to every door in the building.
15) Is the Marks 195S handed, and do I need to specify left or right?
Cylindrical locksets like the 195S are non-handed in the field. The lever chassis mounts either way and the latch face flips, so you order by finish and keying only. What you do need to get right is which side is the outside: the key cylinder sits in the outside lever and the inside lever is always free. On a classroom, the keyed lever faces the corridor.
16) Is a Lockey keyless pushbutton lock an alternative to the Marks USA 195S on a classroom door?
The Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset for doors 1-1/8 inch to 2 inch thick, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function over the same door thickness range. Both are knob trim, not levers. The Marks USA 195S is an ADA compliant American lever lockset, which matters where the opening has to meet accessibility requirements.
17) What finishes does the Marks USA 195S classroom lever come in?
Four finishes: US26D satin chrome, US26 polished chrome, US10B oil-rubbed dark bronze, and US3 bright brass. US26D is the usual pick for schools and institutional corridors because it hides wear and matches most existing commercial trim and closers. If you're matching a fleet of doors, order the same finish code across the group rather than by name, since satin chrome and satin nickel look close but are different codes.
18) Is the Marks 195S rated for a fire door?
The 195S is UL Listed and ANSI/BHMA Grade 1, with a deadlocking latch, which is the latch behavior a positive-latching opening needs. For a labeled fire door assembly, verify the label requirements for that specific opening against the lock's listing before installing, since the door, frame, and closer all carry their own labels.
