Falcon T351PD D 626 – Frequently Asked Questions

1) Will the Falcon T351 closet lock fit a 2 inch thick door?
Yes. The T351 cylindrical lock is built for door thicknesses of 1-3/4 inches up to 2-1/8 inches, so a 2 inch door is inside the range. On a standard 1-3/4 inch commercial door it drops straight in. It is non-handed, so there is no left/right to specify.
2) What does the closet function on the Falcon T351 actually do?
It is a passage/hall/closet function with a keyed outside lever. The lever always retracts the latch from the inside, and the key is there to secure the closet or store room side. There is no thumbturn or pushbutton, and no deadbolt, so nobody gets locked in behind it. If you need a bathroom or bedroom lock with a privacy turn, this is the wrong function.
3) Can the Falcon T351 be keyed into my existing Schlage master key system?
Yes, if your system runs a Schlage C keyway. The T351 takes a C Schlage keyway as an order option alongside Falcon G, E, H, K, L, N, and P. It also accepts small format interchangeable cores and Schlage full size interchangeable cores, so a facility already on SFIC can pin the lock to its own core. Keying is specified on the order as keyed different, keyed alike, or to a supplied key code.
4) Is the Falcon T351 approved for a fire rated door?
The T351 carries a UL 3-hour A label certification, and its outer trim is built so the trim will not let the door fail during a fire. That covers openings up to a 3-hour A label rating in a facility that specifies listed hardware.
5) I need a Grade 1 lever for a 1-3/8 inch door - will the Falcon T351 work?
No. The T351 starts at 1-3/4 inches and runs to 2-1/8 inches, so a 1-3/8 inch door is below its range. For a thinner door in Grade 1, the Dexter C1000 Series covers 1-3/8 inch to 2 inch in classroom, entry/office, classroom security, and asylum functions. The Hager 2510 passage lever also covers 1-3/8 inch to 2 inch, at Grade 2.
6) What is the closest Grade 1 substitute for a Falcon T351 closet lock on a fire-rated opening?
The Corbin Russwin CL3110 is the nearest peer: it is a Grade 1 cylindrical lever lock in the CL3100 series with a passage/closet function and a fire rating, covering doors 1-3/4 inch to 2 inch thick. The Falcon T351 is also a Grade 1 cylindrical lock with a closet function and a 2-3/4 inch backset. The difference to check before ordering is keying - the T351 is a keyed lock accepting a G keyway cylinder, while the CL3110 is a non-keyed passage/closet lever. If the opening needs the key, the T351 is the one that carries it.
7) Is there a Grade 1 passage lever that costs less to spec than a keyed closet lock for interior hall doors?
For an interior hall or closet door that never needs a key, the Design Hardware X75 is a Grade 1 passage lever lockset in the X series with a flat lever, built for 1-3/4 inch doors. The Corbin Russwin CL3110 is another Grade 1 passage/closet lever, rated for 1-3/4 inch to 2 inch doors. Both skip the cylinder entirely. The Falcon T351 is the choice when the closet has to be secured with a key, since it is a keyed single-cylinder lock; on a door that only needs a latch, a passage lever does the same mechanical job without a keying decision.
8) What should I use instead of a Falcon T351 if the door is thinner than 1-3/4 inch?
The Falcon T351 is built for doors 1-3/4 inch to 2-1/8 inch. On a thinner door, the Hager 2510 is a Grade 2 passage cylindrical lever rated 1-3/8 inch to 2 inch, and the Dexter C1000 asylum function lock is a Grade 1 cylindrical lock rated 1-3/8 inch to 2 inch. For a keyed function on a thin door, the Dexter C1000 entry/office is a Grade 1 keyed clutching lever rated 1-3/8 inch to 1-3/4 inch. Confirm the door thickness at the lock prep before choosing, since a chassis sized for a thicker door will not draw up correctly.
9) Is a dummy lever a substitute for a closet lock?
No. A dummy trim is a pull only - it has no latch and no chassis, so it cannot hold a door closed. The BEST 9K series 1DT is a Grade 1 heavy duty non-keyed single dummy trim lever, and the BEST 7KC series 1DT is a Grade 2 medium duty dummy. The Accentra 455LN Augusta is a Grade 1 single dummy in the 5400 series. Those go on the inactive leaf of a pair or on a false door. The Falcon T351 is a cylindrical lock with a 1/2 inch throw latch and an ANSI 1-1/4 inch by 4-7/8 inch strike, so it actually latches the opening.
10) What is the difference between a closet lock and a storeroom lock for a supply room?
A storeroom lock keeps the outside lever locked at all times and requires the key for every entry. 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, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. The Falcon T351 is a closet function lock, keyed single cylinder with a 2-3/4 inch backset. Match the function to how the room is used: a supply room staff enter constantly is usually specified storeroom, while a closet secured against casual access is the closet function.
11) I need a Schlage C keyway on the closet doors to match the rest of the building. What are my options?
The Falcon T351 can be ordered on the C Schlage keyway alongside G, E, H, K, L, N and P, so it keys into a Schlage C system directly. Among the peers, the Cal-Royal AG03 classroom lever and the Cal-Royal AG00 entrance lever are supplied with a 6-pin Schlage C keyway keyed different, and the Arrow MK33 uses a conventional Schlage C keyway cylinder. If the building standard is Schlage C and the door needs a Grade 1 heavy-duty lever, the T351 on the C keyway is the direct match.
12) Can I order the Falcon T351 without a cylinder so my locksmith can core it?
Yes. Three cylinder builds exist: a 6 pin conventional cylinder installed, less 6 pin cylinder, or less small format interchangeable core. The two less-cylinder builds are the ones to order when a locksmith or facility keying department is supplying its own cores to keep a building on one system. Pair that with the None keyway and None keying selections on the order.
13) Is a Grade 1 lock worth it on closet and storage doors, or will a Grade 2 do?
Grade 1 is the heavy-duty commercial tier and the T351 is built for abuse: compression springs behind the rose keep the lever from sagging, the trim is through-bolted with two 10-32 screws, and the inside lever is held by an Allen-head set screw so it cannot be pulled off by hand. That matters on school, dorm, and healthcare storage doors. On a low-traffic office closet a Grade 2 passage lever like the Accentra 5301LN Augusta or the Hager 2510 covers the same function at a lighter duty rating, and the Corbin Russwin CL3110 is the Grade 1 non-keyed passage/closet alternative if you do not need a key at all.
14) What lever styles and finishes can I get the Falcon T351 in to match the rest of my building?
Seven lever designs are offered: Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude, and Quantum. Finishes are 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. For a property manager standardizing a floor, 626 satin chrome is the usual commercial default and lets the closet doors match entry and classroom hardware in the same BHMA finish number.
15) Will the Falcon T351 survive people hanging on the lever in a dorm or school?
That is the abuse it is built for. Pressure Release lets the lever rotate under excessive force rather than transmitting it into the internal lock parts, and the compression springs behind the rose return the lever and stop it drooping over time. The inside lever is retained by an Allen-head set screw, so it cannot be twisted off in a vandalism-prone corridor.
16) Does an electrified cylindrical lever replace a mechanical closet lock on an access-controlled door?
If the door is going onto an access control system, the mechanical lock is the wrong starting point. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC with an NZ lever and D rose, for doors 1-3/4 inch to 2 inch. The Falcon T351 is a non-electronic mechanical lock. A fail safe electrified lever also brings power transfer and door position wiring into the opening, which a mechanical closet lock does not require.
17) What Grade 2 lever lock covers a closet door if Grade 1 is more than the spec calls for?
Several Grade 2 cylindrical levers carry the same passage/hall/closet function. The Accentra 5301LN Augusta is a Grade 2 cylindrical lever in the 5300 series, and the Accentra 4601LN is a Grade 2 passage cylindrical lever in the 4600 series with Augusta trim. The Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell design, rated for doors 1-3/8 inch to 2 inch. The Arrow GL01 is a Grade 2 non-keyed passage lever in the GL series for 1-3/4 inch to 2 inch doors. The Falcon T351 is Grade 1 and heavy duty, which is what a drawing calling for ANSI/BHMA Grade 1 in a high-traffic corridor requires.
18) Which keyed Grade 1 cylindrical lever works for a classroom door instead of a closet lock?
For a classroom opening, the Dexter C1000 classroom lock is a Grade 1 keyed clutching cylindrical lever for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom security version is a Grade 1 keyed clutching lever in the same thickness range. The Cal-Royal AG03 is a classroom lever in the AG series with a 6-pin Schlage C keyway and a 2-3/4 inch backset. The Falcon T351 is a closet function lock and is not a classroom function, so it should not be substituted onto a door the drawing calls out as classroom.
19) Can I use a keyless pushbutton lever on a closet instead of a keyed lock?
You can, if you want to stop issuing keys for that door. The Lockey 2835 is a mechanical pushbutton keyless lever with passage function and ADA compliance for doors 1 3/16 inch to 2 inch, and the Lockey 2835DC adds a double combination in the same thickness range. The Lockey 1150 is a heavy duty mechanical keypad lever set with passage function for 1-1/8 inch to 2 inch doors. The tradeoff against the Falcon T351 is key control: the T351 is a keyed single cylinder lock that accepts a G keyway and folds into an existing master key system, which a combination lock cannot do.
20) Is a residential passage lever an acceptable swap for a commercial closet lock in an apartment building?
They are not equivalent. The Kwikset 200BRNL Breton is a Grade 3 passage lever for doors 1-3/8 inch to 1-3/4 inch, and the Callan Asheville is a Grade 3 passage leverset. The Bravura Atlanta, Orlando and Tampa passage leversets are Grade 2. The Falcon T351 is a Grade 1 heavy duty commercial lock with through-bolted trim and compression springs behind the rose to prevent lever sag. On a corridor or common-area closet in a multi-family property, the Grade 1 commercial chassis is what holds up to the cycle count; behind a unit door, a lighter grade lever is often what the spec allows.
21) What do I order for a utility or mechanical room where both levers stay locked and the key retracts the latch?
That is an asylum or institution function. The Dexter C1000 asylum lock is a Grade 1 cylindrical lock with the F87 asylum function for doors 1-3/8 inch to 2 inch, and the Arrow MK33 is a heavy duty asylum, institution and utility function cylindrical lock with a ball knob and a conventional Schlage C keyway cylinder. The Falcon T351 is a closet function keyed lever, so it does not deliver key operation on both sides. Where a facility standard calls for lever trim on the accessible route, the Dexter is the lever option of the two.
22) If the closet is inside a restroom or bedroom, is a privacy lever the right part instead?
A privacy lock uses an inside button and an emergency release rather than a key. The Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, the Arrow MK02 is a Grade 1 non-keyed privacy cylindrical lock with a Tudor knob for 1-3/4 inch to 2 inch doors and carries a fire rating, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors. The Falcon T351 is a keyed closet lock, so it secures the door against everyone without a key rather than giving an occupant a thumbturn.
23) The existing closet doors have knobs. Can I switch to a lever without changing the door prep?
The Falcon T351 is a non-handed cylindrical lever with a 2-3/4 inch backset, a 3-1/2 inch rose and an ANSI 1-1/4 inch by 4-7/8 inch strike with a 1-3/16 inch lip, and it can also be ordered on 2-3/8 inch or 3-3/4 inch backset. Knob peers such as the Arrow MK02 with the Tudor knob and the Arrow MK33 with the ball knob are the same cylindrical bored family. Verify the existing backset and the strike prep in the frame against those numbers; the rose diameter matters most where you are covering an older trim footprint. Lever trim is also the form most facilities standardize on for accessible routes.
24) How much of the door face does the Falcon T351 rose cover?
The rose is 3-1/2 inches in diameter, which is larger than a typical residential trim ring and covers up an older bore or a scarred door face when you are replacing hardware. It also gives the through-bolted trim a wider bearing surface on the door. Worth checking against narrow stiles and against any adjacent flush pull or edge trim before you order.
