Hager 3495 WTN US26D – Frequently Asked Questions

1) Will the Hager 3495 classroom security lock fit a 1-3/8 inch door, or does it need a 1-3/4 inch door?
Door thickness on the 3495 runs 1-3/8 inches to 2 inches, so it covers the older 1-3/8 inch interior doors, the standard 1-3/4 inch commercial door, and thicker 2 inch leaves without any special order. Backset is 2-3/4 inches, the usual commercial bore centerline, so a door already prepped for a Grade 1 cylindrical lock takes it as-is. That range is wider than a lot of Grade 1 competition: the Dexter C1000 classroom security lever tops out at 1-3/4 inches.
2) What does the intruder classroom function on the Hager 3495 actually do during a lockdown?
The 3495 is an intruder classroom lock, function F110. A key cylinder in each lever lets a teacher lock the outside lever from inside the room, so nobody has to step into the corridor to secure the door during a lockdown. The inside lever always retracts the latch for free egress. The latch is a 1/2 inch throw stainless deadlocking latchbolt, which resists being carded once the door is shut. If you want the older arrangement where the door can only be locked and unlocked from the corridor side, that is standard classroom function, not classroom security, and the Dexter C1000 classroom lever is that version.
3) Do I have to specify handing when I order a Hager 3495 lever lock?
No handing to call out. The 3495 is non-handed, so one lock covers left and right hand openings and a maintenance shop can stock a single part number for a whole building. You do still pick lever design (Archer, August, or Withnell), finish, and whether you want the standard cylinder or SFIC prep.
4) Can I get the Hager 3495 with a small format interchangeable core so it goes on our existing BEST keying system?
SFIC prep is an orderable option on the 3495, and every lever design and finish combination is offered both ways. The SFIC version ships less core, so you supply or order the core separately and key it into whatever SFIC system the building already runs. If you are not on an interchangeable core system, the standard cylinder version comes in Schlage C keyway, with other keyways available on request.
5) Will the Hager 3495 work in the strike prep we already have in our hollow metal frames?
The 3495 ships with a 1-1/4 x 4-7/8 inch ASA strike, which is the standard commercial curved lip strike prep in hollow metal frames. If your frames were prepped for another Grade 1 cylindrical lock with an ASA strike, the new lock drops into the existing cutout. The 1/2 inch latch throw is standard cylindrical throw, so latching depth against that strike is unchanged.
6) Is the Hager 3495 approved for a 3 hour fire rated classroom door?
UL and cUL listed for all functions up to 3 hours on A label single doors, with a UL10C positive pressure rating. It is also ADA compliant per ANSI A117.1, meets ANSI A250.13 for severe windstorm, and carries Miami Dade County approval, which matters if you are specifying for a school in a hurricane zone that doubles as a shelter.
7) We are standardizing classroom hardware across a district. Can we run one part number for every door?
Mostly, yes. The 3495 is non-handed, so left and right hand doors take the same lock, and its 1-3/8 to 2 inch thickness range covers the mixed door stock typical of a district with buildings from different decades. Order it SFIC prep and key the whole district into one interchangeable core system, then rekey a room by swapping a core instead of pulling the lock. Standard ASA strike prep means older frames generally accept it without new frame work.
8) What is the closest equivalent to the Hager 3495 classroom security lever from another manufacturer?
The Dexter C1000 Series classroom security cylindrical lever lock is the closest match. Both are Grade 1 keyed cylindrical lever locks built for the classroom security function, where a key on either side controls the outside lever so a teacher can lock the door from inside the room without stepping into the corridor. The difference that matters on a job walk is door thickness: the Hager 3495 covers 1-3/8 inch to 2 inch doors, while the Dexter C1000 classroom security lock is listed for 1-3/8 inch to 1-3/4 inch. On a 2 inch door the Hager is the one that fits.
9) Difference between a classroom lock and a classroom security lock when specifying for a school?
A standard classroom function, such as the Dexter C1000 Series Grade 1 classroom cylindrical lever lock, is keyed from the outside only, so locking down the room means opening the door and reaching into the hallway with the key. A classroom security or intruder classroom function, such as the Hager 3495 or the Dexter C1000 classroom security lock, adds a keyed cylinder on the inside that locks and unlocks the outside lever from within the room. Both Dexter versions are Grade 1 and cover 1-3/8 inch to 1-3/4 inch doors; the Hager 3495 covers 1-3/8 inch to 2 inch. If a district lockdown policy requires locking from inside the classroom, the plain classroom function will not satisfy it.
10) Is a Grade 1 lock worth it for a school corridor, or will Grade 2 hold up?
The 3495 is BHMA certified to ANSI A156.2 Series 4000 Grade 1, the extra heavy duty commercial tier, with a heavy gauge steel chassis, zinc dichromate coated, and thru-post mounting. On a classroom door taking hundreds of cycles a day plus abuse from the lever, that is the tier written into most school specs. Grade 2 cylindrical levers exist for lighter traffic, the Cal-Royal AG03 classroom lever is a Grade 2 option, but a spec calling out Grade 1 will not accept it.
11) What finishes does the Hager 3495 come in, and will it match the rest of our building?
Five finishes across all three lever designs: 605 bright brass, 606 satin brass, 613 satin bronze oil rubbed, 625 bright chrome, and 626 satin chrome. 626 satin chrome is the workhorse in schools and institutions and matches most existing commercial hardware. Exposed trim is wrought brass, bronze, and stainless steel, so the finishes are on solid material rather than plated pot metal.
12) What is the rose diameter on the Hager 3495, and will it cover the marks left by the old lock?
Rose diameter is 3-17/32 inches (90 mm). On a retrofit that usually covers the wear ring and screw marks left by an older cylindrical lockset, and there are no exposed mounting screws on the face, so the finished look is clean. Bore prep is standard cylindrical at a 2-3/4 inch backset.
13) Should I use a cylindrical lock like the Hager 3495 or a mortise lock on a classroom door?
A cylindrical lock like the 3495 goes into a standard bored prep, installs faster, and is cheaper to replace when a lever gets abused, which is why it dominates classroom doors. A mortise lock needs a pocket routed into the door edge and is the call when you need a deadbolt and latch in one case or an auxiliary function the bored chassis cannot do. If the door is already bored, stay cylindrical: the 3495 is Grade 1 and covers 1-3/8 to 2 inch thickness, so it fits nearly any existing bored opening.
14) I need an electrified lever for access control on the same door type. Is the Hager 3495 an option?
The 3495 is a mechanical key operated lock with no electrified variant, so it will not tie into an access control system. For a Grade 1 cylindrical lever with power, the Corbin Russwin CL33903 is a fail safe electrified lever at 12V AC/DC covering 1-3/4 to 2 inch doors. Use the 3495 where lockdown is done by key at the door and the budget stays mechanical.
15) Is there a Grade 2 classroom lever if the opening does not need Grade 1?
The Cal-Royal AG03 classroom lever is a Grade 2 cylindrical lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset. It shares the 2-3/4 inch backset and Schlage C keyway with the Hager 3495, so it drops into the same door prep and keys into the same master system. What it does not carry is the Hager's Grade 1 rating or the intruder classroom function that locks the outside lever from inside the room. For a storage or office corridor door in a school it is a straight fit; for a classroom under a lockdown mandate it is not.
16) What should I use on a door that needs to stay latched but never locked, next to a run of Hager 3495 classroom locks?
For a corridor, hall, or closet door that only needs latching, a Grade 1 passage lever keeps the same heavy duty chassis class without a cylinder. The Falcon K101 is a Grade 1 heavy duty non-handed passage cylindrical lock, fire rated, covering 1-3/8 inch to 2-1/4 inch doors; the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for 1-3/4 inch to 2 inch doors. Both are non-keyed, so they will not take a key from the same system the keyed Hager 3495 uses.
17) Can a storeroom lever be substituted for an intruder classroom lock?
Not for the lockdown application. The Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors; storeroom function keeps the outside lever locked at all times and the key retracts the latch, with no way to change the lock state from inside the room. The Hager 3495 intruder classroom function is keyed to lock and unlock the outside lever from the inside, which is the behavior a classroom lockdown requires. The AG05 suits a supply room or mechanical space that stays secured around the clock.
18) What is the Grade 1 option for an office or entry door where the occupant locks it with a key from outside?
The Dexter C1000 Series entry/office cylindrical lever lock is Grade 1, keyed, with a clutching lever, listed for 1-3/8 inch to 1-3/4 inch doors. Entry/office lets the outside lever be locked or left free, which is what a private office or conference room wants. It differs from the Hager 3495 in function only, not in grade class: the Hager carries the intruder classroom function intended for rooms that need to be secured from the inside during a lockdown, and covers doors up to 2 inch thick.
19) What goes on a patient room or holding room door instead of a classroom security lock?
Asylum or institution function is the one specified where a room must be operated by key from both sides with no free egress by lever. The Dexter C1000 Series asylum lock (F87) is Grade 1 for 1-3/8 inch to 2 inch doors, matching the Hager 3495 door thickness range; the Arrow MK33-BD-CS is an asylum function lock with a ball knob and a conventional Schlage C keyway cylinder. The Hager 3495 differs in that its inside lever always releases the latch for egress, which is required in a classroom but not what a holding room calls for.
20) Is an electrified cylindrical lever an alternative for access control on a classroom door?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running on 12VAC/DC for 1-3/4 inch to 2 inch doors. Fail safe means the outside lever unlocks when power drops, which is the opposite behavior from the mechanical Hager 3495, where lock state is set by key and holds through a power outage. Where a classroom is tied into a card system and central lockdown, the electrified lever is the right part; where lockdown is initiated by the teacher with a key in the room, the 3495 is.
21) Can I use a Kwikset or other Grade 3 residential lever on school and commercial doors?
Grade 3 levers such as the Kwikset 200BRNL Breton passage lever, listed for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AUS00 entrance/office lever, also 1-3/8 inch to 1-3/4 inch, are built for residential traffic. The Hager 3495 is a Grade 1 commercial lock tested to ANSI A156.2 Series 4000 for extra heavy duty commercial use, with UL/cUL listing for up to 3 hour A label single doors. On a rated corridor or classroom opening the Grade 3 lever will not meet the fire or cycle requirement; on an apartment interior bedroom or closet door it is a normal choice.
22) Which classroom-family lock should I standardize on across a district running Schlage C keyways?
Two options in the classroom family carry the Schlage C keyway. The Cal-Royal AG03 classroom lever uses a 6-pin Schlage C keyway keyed different with a 2-3/4 inch backset and is Grade 2. The Hager 3495 is Grade 1 with Schlage C standard and a 2-3/4 inch backset, and adds an SFIC prep option less core, which lets a district move to interchangeable cores later without replacing chassis. Both share the 2-3/4 inch backset, so a facility standardizing on one prep can mix them across function without redrilling doors.
23) Can I get a Hager 3495 lead lined for an X-ray room door?
Lead lining is a listed option on the 3495, so the same Grade 1 classroom security lever can go on a radiology or imaging suite door without breaking the shielding. That is a build option to call out on the order, not something added in the field.
24) What is the difference between the Archer, August, and Withnell levers on the Hager 3495?
All three are lever designs on the identical Grade 1 chassis, so function, backset, latch, and door thickness range do not change with the choice. It is purely trim style and grip shape, and all three are offered in every one of the five finishes and in both standard cylinder and SFIC prep. Pick whichever matches the lever profile already on your other doors.
25) Will a keyless pushbutton lever work in place of a keyed classroom security lock?
They solve different problems. The Lockey 2835 mechanical pushbutton keyless lever lock has a passage function and fits 1 3/16 inch to 2 inch doors, and the Lockey 1150 mechanical keypad lever set is a heavy duty passage-function set for 1-1/8 inch to 2 inch doors. Code-based entry means no key and no keying system, so these do not join the Schlage C master system the Hager 3495 uses, and their passage function does not provide the keyed inside control that defines the 3495 intruder classroom function. Keyless suits a shared back-of-house door where handing out keys is the problem.
26) What matches a Hager 3495 on the inactive leaf of a pair or on a door with no latch?
A dummy trim gives the same lever appearance with no chassis or latch. The BEST 9K Series 1DT single dummy trim is a Grade 1 non-keyed heavy duty cylindrical lever trim, and the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever. Both are Grade 1 like the Hager 3495, but a dummy is a pull only, so it will not latch, lock, or take a key.
