Falcon W511PD ELI 626 – Frequently Asked Questions

1) Will the Falcon W511 knob lock work on a 1-3/8 inch door, or is it only for 1-3/4?
The W511 Entry/Office knob lock covers 1-3/8 inch through 1-3/4 inch doors, so it drops onto both an older interior wood door and a standard commercial 1-3/4 inch door without a different chassis. Door prep is a 2-1/8 inch cross bore with a 1 inch edge bore, and the standard backset is 2-3/4 inches.
2) Will the Falcon W511 latch into the strike already in my frame?
Depends on what is cut into the frame. The W511 uses a 1/2 inch throw stainless latch, and the standard strike is the ANSI 1-1/4 x 4-7/8 inch curved lip. If your frame is prepped for that ANSI cutout, it drops in. If it is an older wood frame with a small strike, pick one of the other strike options instead: the 30-149 T-strike at 1-1/8 x 2-3/4 with a 1-3/8 inch lip, or the 1-5/8 x 2-1/4 full lip strikes with a 1 inch lip in radius (30-150) or square (30-151) corner. With only 1/2 inch of throw, strike alignment has to be right or the latch will not seat.
3) What does Entry/Office function actually do on the Falcon W511 knob lock?
F86 Entry/Office is the office door function: the key retracts the latch from outside, and the inside knob is always free for egress. It is a single cylinder lock, keyed one side only, so there is no key needed to get out. If you want a door that stays locked outside at all times with no way to leave it unlocked, that is storeroom function, not this one.
4) Can I get the Falcon W511 keyed into my existing Schlage master key system?
Yes, if your system runs a C keyway. The W511 keyway is selectable and the choices are C (Schlage), G, E, H, K, L, N and P, plus a less-cylinder option if your locksmith is supplying the cylinders. Keying is ordered as KD keyed different or KA keyed alike, with a key code field if you already have one assigned. G is the Falcon standard keyway on the spec.
5) Can the Falcon W511 take a small format interchangeable core?
Yes. Cylinder is an order choice: a 6 pin conventional cylinder, less 6 pin cylinder, or less SFIC, so you can buy the lock prepped for a small format interchangeable core and drop in your own cores. Falcon states SFIC cylinders and cores from other manufacturers work in it, which is how a locksmith folds it into an existing house system without rekeying anything else.
6) What else is comparable to the Falcon W511 Entry/Office knob lock from another brand?
The closest straight equivalent is the Dexter C2000 Series entry/office ball knob lock, Grade 2, keyed, for 1-3/8 to 1-3/4 inch doors, same function and same door range. Corbin Russwin's CK4851 is another entrance/office cylindrical knob with a conventional cylinder that goes out to 2 inch thick doors if yours are heavier than 1-3/4. On the lighter end, Cal-Royal's BER00 and Pamex's FTF Baron are Grade 3 entrance/office knobs for 1-3/8 to 1-3/4 inch doors, which suits light residential traffic but not a commercial corridor.
7) Which alternative keyed knob suits a door thicker than 1-3/4 inches?
The Corbin Russwin CK4851 entrance/office cylindrical knob lock with conventional cylinder covers doors from 1-3/8 inch to 2 inch. The Falcon W511 accommodates door thickness from 1-3/8 inch to 1-3/4 inch, so on a thicker door the Corbin Russwin is the one that fits. Among non-keyed knobs the Corbin Russwin CK4310 passage/closet knob also runs 1-3/8 inch to 2 inch.
8) The door does not need to lock - what takes the place of a Falcon W511 on a hall or closet opening?
Use a passage knob instead. The Falcon W511 is a keyed single cylinder entry/office lock, so it is the wrong function for an opening that never locks. The Dexter C2000 passage ball knob is a Grade 2 non-keyed passage lock for doors 1-3/8 inch to 1-3/4 inch, and the Corbin Russwin CK4410 is a Grade 2 non-keyed passage/closet cylindrical knob over the same range. The Arrow MK01 and RK01 are also Grade 2 non-keyed passage knobs for 1-3/8 inch to 1-3/4 inch doors.
9) The opening needs a heavier lock than a Grade 2 knob - what steps up from the Falcon W511?
The BEST 8K series entrance function knob lock is a Grade 1 heavy duty single cylinder knob, where the Falcon W511 is Grade 2 medium duty. For a keyed knob on a heavier chassis in a storeroom function instead of entrance, the Sargent 8XG04 is a Grade 1 heavy duty single cylinder knob lock with a 2-3/4 inch backset, matching the W511 backset.
10) For a classroom door, is the Falcon W511 the right function or is there a better keyed knob?
The Falcon W511 is an entry/office function, where the outside knob is locked and unlocked from the inside. A classroom door that must be locked from the corridor by key calls for a classroom function instead: the Dexter C2000 classroom cylindrical ball knob is a Grade 2 keyed classroom lock for doors 1-3/8 inch to 1-3/4 inch. For a keyed knob that stays locked outside at all times, the Sargent 6G04 is a Grade 2 storeroom/closet single cylinder knob lock.
11) Which knobs look like a Falcon W511 substitute but will not actually lock the door?
Dummy trim is the trap. The BEST 6K series single dummy trim is a Grade 2 medium duty non-keyed knob, the Schlage A170 single dummy trim is a Grade 2 knob for doors 1-3/8 inch to 1-7/8 inch, and the Bravura Biloxi is a Grade 2 dummy knobset. All three read as Grade 2 cylindrical knobs on paper, but they are pull trim with no latch and no cylinder. The Falcon W511 is a keyed single cylinder lock with a 1/2 inch throw latch, so a dummy will not replace it on a door that has to secure.
12) Can a Kwikset Polo keyed entry knob be used where a Falcon W511 is specified?
They are not interchangeable on a specified commercial opening. The Kwikset 400P-CP Polo keyed entry knob is Grade 3 and fits doors 1-3/8 inch to 1-3/4 inch, shipping with a round corner adjustable latch and round corner strike. The Falcon W511 is Grade 2, catalogued for commercial use, UL listed for 3 hour A label fire doors, and ships with an ANSI 1-1/4 inch by 4-7/8 inch curved lip strike. If the opening is a fire-rated or spec-driven commercial door, the grade and the fire listing are the deciding differences.
13) Do I have to order the Falcon W511 handed for a left or right hand door?
No handing to specify. The W511 is non-handed and field reversible, so one part number covers left and right hand openings and you do not have to take the chassis apart to flip it. For a property manager stocking spares across a building, that means one lock on the shelf instead of two.
14) What do I have to specify when ordering a Falcon W511 so I get a complete lock?
Five things: knob design (Elite or Hana), finish, cylinder (6 pin conventional, less 6 pin, or less SFIC), keyway and keying (KD or KA, with key code if you have one), the latch backset and face style, and the strike. The lock ships with the latch and strike you pick plus through-bolts and mounting screws, so nothing extra is needed beyond a correctly prepped door.
15) Is a Grade 2 knob lock like the Falcon W511 enough for a high traffic office door, or do I need Grade 1?
Grade 2 medium duty is the normal specification for offices, retail and multi-family unit doors. For a door that gets hammered all day, a school entry or a mechanical room in constant use, step up to Grade 1: the BEST 8K Series entrance knob lock is a heavy duty Grade 1 in the same entrance function, and Sargent's 8XG04 is a Grade 1 heavy duty storeroom knob on a 2-3/4 inch backset. If it is an office door where the inside knob must stay free, the W511 is the right grade.
16) Can I order a set of Falcon W511 locks keyed alike so one key opens every unit door?
Yes. Keying is a required order choice between KD keyed different (each lock its own key) and KA keyed alike, and there is a key code field if the property already runs an assigned code. For a landlord or property manager standardizing a building, order KA on the group that should share a key and KD on the rest.
17) Is a Grade 2 entrance knobset from a residential-style line the same thing as a Falcon W511?
Not on a fire door. The Callan Edgewood and Callan Roland are Grade 2 entrance knobsets, matching the Falcon W511 on grade, and the Bravura Dallas is a Grade 2 passage knobset in a US4 satin brass finish. The W511 is UL listed for 3 hour A label fire door use and certified to ANSI/BHMA A156.2 Series 4000 Grade 2, which is what a fire-rated commercial opening is checked against.
18) Is there a lighter-duty keyed entry knob than the Falcon W511 for an interior office door?
Yes. The Pamex FTF Baron knob lockset is a Grade 3 entrance/office knob for doors 1-3/8 inch to 1-3/4 inch, and the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway over the same door thickness range. The Falcon W511 is Grade 2 and certified to ANSI/BHMA A156.2 Series 4000 Grade 2, so if the specification on the drawing calls for Grade 2 the Grade 3 units will not satisfy it.
19) What is the alternative to a Falcon W511 if keys are not wanted on the opening at all?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors 1 3/16 inch to 2 inch. It secures by code rather than by cylinder, so there is no keyway to key alike and no core to service. The Falcon W511 is a keyed single cylinder lock with a G keyway and takes a 6 pin conventional cylinder or an SFIC core, which is what makes it fit into an existing master key system.
20) The opening has an exit device on it - can a Falcon W511 knob lock be used there?
No, that is a different part. An exit device opening takes knob trim built for the device: the Sargent 28C-KNOB is exit device trim with knob and rose in an entrance function for 1-3/4 inch doors, and the Imperial USA ED-BKL580 is storeroom function knob trim in the ED-500 series. The Falcon W511 is a cylindrical bored lock installed in a 2-1/8 inch cross bore with a 1 inch edge bore, not trim that mounts to a device chassis.
21) Standardizing a multi-family property on one keyed knob - how do the Grade 2 candidates compare to the Falcon W511?
Among the Grade 2 keyed entrance knobs, the Falcon W511 carries a G keyway and can be ordered less small format interchangeable core, which lets units drop into an existing SFIC master system, and it is UL listed for 3 hour A label fire doors. The Dexter C2000 entry/office ball knob is Grade 2 for doors 1-3/8 inch to 1-3/4 inch and is non-clutching. The Cal-Royal BER00 entrance/office knob is Grade 3 with a Kwikset keyway, which is a different keying platform to standardize on.
22) What finishes does the Falcon W511 knob lock come in to match the rest of my building?
Eight finishes: 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. 626 satin chrome is the usual commercial standard if you are matching existing office hardware.
23) Does the Falcon W511 need power or wiring run to the door?
No. The W511 is a purely mechanical cylindrical knob lock, no electronics, no wiring, no power supply. It works the same when the building loses power. If you want keyless entry without running wire, the Lockey 3830 is a mechanical combination knob lock covering 1 3/16 inch to 2 inch doors.
24) Will the Falcon W511 knob sag over time like the old ones did?
The W511 chassis uses heavy duty torsion springs specifically to keep the knob from sagging, with brass and cold-formed steel internals, zinc plated with a dichromate finish for rust resistance. The latch front is self-adjusting and works against either a beveled or a flat door edge, so a slightly out-of-square door will not fight it.
25) For a decorative entry knob on a front or tenant door, what are the alternatives to a Falcon W511?
The Deltana 3381 Egg Knob, 6171 Round Knob, and 6112 St. Thomas knob all cover doors 1-3/8 inch to 2 inch, with the 3381 and 6171 in an entry function and the 6112 in privacy. The Deltana 6901 Portland Knob is an entry function for 1-3/8 inch to 1-3/4 inch doors. The Falcon W511 is the commercial-line choice, Grade 2 medium duty with a G keyway, and its finishes run from bright brass and satin brass through oil-rubbed satin bronze, satin nickel, matte black, bright chrome, satin chrome, and aged bronze.
26) Is a Sargent 78-2875 outside knob or a Kwikset Polo passage knob a way to replace half of a Falcon W511?
No. The Sargent 78-2875 is an outside knob only with B design in the 7800 series, a trim piece rather than a complete lock. The Kwikset 200P Polo passage knob is an interior hall and closet lock supplied with a 6AL latch and RCS round corner strike, and it is a passage function with no cylinder. The Falcon W511 is a complete keyed single cylinder entry/office lockset, so neither of these covers the same opening.
