Marks USA 295DB/26D-G3 – Frequently Asked Questions

1) Will the Marks USA 295DB fit a 1-3/8 inch door?
Not as it ships. The 295DB cylindrical leverset is built for doors 1-5/8 inches to 1-7/8 inches thick. For a 1-3/8 inch door you need the K1904 spacer, which Marks offers for that purpose. Standard 1-3/4 inch commercial doors fall inside the stock range with no extra parts.
2) What backset does the Marks 295 Series leverset use, and can I get it for a 2-3/8 inch bore?
The 295DB is set up for a 2-3/4 inch backset, which is the usual commercial door prep. Marks also builds the 295 with a 2-3/8 inch backset, so if the existing cross-bore on your door is the residential-depth prep, specify that version rather than trying to shim the 2-3/4.
3) Will the Marks 295DB latch into the strike already in my frame?
Depends on what is in the frame now. The 295DB comes with the Marks #1135 strike, a 4-7/8 inch ASA curved lip strike, and the #1834 latch has a 1-1/8 x 2-1/4 inch front with a 9/16 inch deadlocking throw. If your frame already has a standard 4-7/8 inch ASA strike cutout, the included strike drops straight in. A T-strike or a full-lip residential strike prep will need the frame reworked or the frame prep changed.
4) Can the Marks 295DB go on a fire rated door in a school corridor?
Yes. The 295DB carries a 3-hour fire rating and is UL Listed, so it is suitable for fire rated door assemblies up to that rating. The deadlocking latch and ANSI/BHMA Grade 1 chassis are what the rating rests on, and the lever trim is ADA compliant for accessible openings.
5) What is the closest electronic alternative to the Marks USA 295DB if we want classroom intruder lockdown with credentials instead of a key?
The TownSteel XCE-9000 is the direct counterpart: a Grade 1 electronic classroom intruder cylindrical lockset with a keypad, fitting doors 1-3/4 inch to 2 inch. The Marks USA 295DB delivers the same intruder lockdown intent mechanically, using a Marks C keyway 6-pin cylinder, and fits 1-5/8 inch to 1-7/8 inch doors with an optional K1904 spacer for 1-3/8 inch. Choose the 295DB where you want no batteries or programming in the opening, and the XCE-9000 where you want code-based lockdown and no key handling by staff.
6) Our doors are 2 inches thick. Will the Marks USA 295DB work, or do we need a different lock?
The Marks USA 295DB chassis is built for 1-5/8 inch to 1-7/8 inch doors, with a K1904 spacer for 1-3/8 inch, so a 2 inch door falls outside its range. For thicker doors, the Cal-Royal CAL30 passage lockset covers 1-3/8 inch to 2 inch and the Dorma C150 entry/office lock covers 1-3/8 inch to 2-1/4 inch, both Grade 1. Note that neither of those is a classroom intruder function, so if lockdown is the requirement you should confirm the actual door thickness before substituting.
7) Is a keypad lock like the Alarm Lock DL2700 a substitute for the Marks USA 295DB on classroom doors?
Not function-for-function. 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 1-5/8 inch to 1-7/8 inch doors - the same door thickness range the Marks USA 295DB covers. But the DL2700 is an entrance lock, while the 295DB is built for classroom intruder lockdown with a Marks C keyway 6-pin cylinder. If your door schedule calls for intruder function, the DL2700 solves code-based access, not lockdown.
8) Is the Stanley QCL150 a drop-in for the Marks USA 295DB since both use a 2-3/4 inch backset and an ASA strike?
They share prep but not function or grade. The Stanley QCL150 is a Grade 2 entry lever with a Sierra bent lever, 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 295DB also runs a 2-3/4 inch backset and ships a 4-7/8 inch ASA curved lip Strike #1135, but it is Grade 1 with classroom intruder function and a 9/16 inch deadlocking latch throw. On an entry door with no lockdown requirement the QCL150 fits the same bore; on a classroom intruder opening it does not meet the function.
9) Is a cylindrical leverset like the Marks 295 enough for a high traffic school door, or should I be specifying a mortise lock?
For most classroom and corridor openings a Grade 1 cylindrical lock is the accepted spec, and the 295 chassis is rated past 3.6 million cycles, which Marks states is 300 percent beyond BHMA Grade 1. The stainless steel clutch disengages the levers from the retractor when locked, so someone yanking on a locked lever does not wear the retractor or cause lever droop, which is the usual failure on school doors. Step up to a mortise lock when you need auxiliary deadbolt security or multiple functions in one case.
10) What keyway and how many keys come with the Marks 295DB?
It uses the Marks "C" keyway with a 6-pin conventional cylinder, and two keys are supplied. If your building is keyed to a different manufacturer's keyway, plan on either rekeying to the Marks C section or ordering the lock less cylinder so you can fit your own.
11) What are my options if I want classroom lockdown but with a keypad instead of a key?
The Marks 295DB is a mechanical lockset operated by key, so lockdown is done at the door with the key in hand. If you want credential or code based lockdown instead, ZenSupply carries the TownSteel XCE-9000 Series electronic classroom intruder cylindrical lockset with keypad, Grade 1, for 1-3/4 to 2 inch doors, and the TownSteel FCE-4000 Series RFID electronic intruder classroom lockset for 1-3/4 inch doors. Both are heavy duty Grade 1 like the Marks, but they add batteries and programming to the maintenance load.
12) I need a plain Grade 1 lever with no key for closets and equipment rooms. Is the Marks 295 the right one?
For non keyed openings there is no reason to pay for a cylinder. The Cal-Royal CAL30 Calypso Series is a Grade 1 extra heavy duty passage lockset covering 1-3/8 to 2 inch doors, which is a wider thickness range than the Marks 295 chassis handles. For bathrooms and similar privacy openings, the Cal-Royal CAL20 is the Grade 1 privacy version in the same series.
13) What is a lighter-duty lever lockset if the Marks USA 295DB is more chassis than our interior doors need?
For interior openings without lockdown requirements, the Orca OCL210 is a Grade 2 medium duty passage cylindrical lockset and the Orca OCL240 is the Grade 2 medium duty privacy version; the Dorma CL701 is a Grade 2 non-keyed single dummy lever for openings that need trim only. The Marks USA 295DB is a Grade 1 commercial cylindrical lock with a deadlocking latch and a 3-hour fire rating, so keep it on the fire-rated and high-traffic doors and use the lighter chassis where the door is not rated.
14) Can I use a Lockey mechanical pushbutton lock instead of the Marks USA 295DB to avoid issuing keys?
The Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function for 1-1/8 inch to 2 inch doors, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with adjustable backset over the same thickness range. Both are knob trim and code-entry, not lever trim. The Marks USA 295DB is an ADA compliant lever set with a cast Crescent lever, so for openings governed by ADA lever requirements the Lockey knob locks are not an equivalent.
15) If we want the classroom lock tied into an access control system rather than standalone like the Marks USA 295DB, what are the options?
The Schlage NDEB is a Grade 1 heavy duty ENGAGE Series wireless cylindrical lock using 2.4 GHz Bluetooth Low Energy, offered in storeroom, office, privacy and apartment functions for 1-5/8 inch to 2 inch doors. The SDC Electra 7200 is a solenoid controlled cylindrical lock on dual voltage 12/24VDC for 1-3/4 inch to 2 inch doors, which suits a hardwired access control run. The Marks USA 295DB stays mechanical with a Grade 1 chassis and 3-hour fire rating, so it carries no wiring, batteries or head-end dependency.
16) What is the difference between the Marks USA 295DB and the Schlage XE360M for a classroom opening?
The Schlage XE360M is a Grade 1 wireless tubular lock with an offline push button function and a smart mobile reader, in classroom/storeroom function for 1-3/4 inch doors. The Marks USA 295DB is a cylindrical chassis, not tubular, running cast retractors on bronze roller bearings with a stainless steel clutch that disengages the levers when locked. The XE360M gives you mobile credentials; the 295DB gives you a keyed mechanical lockdown with a 3-hour fire rating and no power at the door.
17) What finish does the Marks 295DB Crescent lever come in?
US26D satin chrome is the finish offered on the 295DB. That is the standard commercial finish, so it matches most existing school and office door hardware without a special order. The Crescent lever itself is solid cast zamac with a 1/2 inch return, and the roses are 3-7/16 inch diameter, thru-bolted with two #10 bolts.
18) Can I standardize a whole building on the Marks 295 chassis if some doors need entry or storeroom function?
The 295 is a full commercial series built on one chassis, so functions within the series share the same 2-3/4 inch backset, the #1834 latch with 9/16 inch throw, and the 4-7/8 inch ASA strike prep. That means one door prep across the building and one spare parts shelf. Where you need an electronic opening in the same fleet, the Schlage NDEB ENGAGE Series is a Grade 1 cylindrical that covers 1-5/8 to 2 inch doors, overlapping the same thickness range.
