Falcon W501PD ELI 626 – Frequently Asked Questions

1) Will the Falcon W501 entry knob lock fit a 1-3/8 inch door?
Yes. The W501 cylindrical knob lock covers doors from 1-3/8 inches through 1-3/4 inches, so it works on both older interior doors and standard commercial 1-3/4 inch openings without a thickness kit. Standard backset is 2-3/4 inches, which is the usual commercial bore location.
2) Do I have to order the Falcon W501 knob lock left or right handed?
No. The W501 is non-handed and does not need field disassembly to re-hand, so one part number covers left and right hand openings. For a property manager stocking spares across a building, that means a single lock on the shelf fits any door.
3) Can I get the Falcon W501 keyed alike with the other locks in my building?
Yes. Keyed alike is a selectable option at order, alongside keyed different, and you can enter a key code if you are matching an existing system. Keyways offered are C (Schlage), G, E, H, K, L, N and P, so if your building is already on a Schlage C keyway you can order the W501 on C and keep one key. Standard cylinder is 6 pin conventional.
4) Can I order the Falcon W501 without a cylinder so I can install my own SFIC core?
Yes. Beyond the standard 6 pin conventional cylinder, the W501 can be ordered less 6 pin cylinder or less small format interchangeable core, so a locksmith or facility with its own keying system supplies the core. The lock takes interchangeable cores including cores built by other manufacturers, and the core pulls for re-keying without taking the lock off the door.
5) Is a Grade 2 knob lock like the Falcon W501 enough for a high traffic commercial door?
The W501 is rated medium duty, Grade 2, which suits commercial doors that do not see constant cycling: private offices, back-of-house, apartment entries, storage rooms. On a main entrance or a school corridor door that gets used all day, step up to a Grade 1 heavy duty knob lock. The BEST 8K Series entrance function single cylinder knob is the Grade 1 heavy duty equivalent in the same function, and the Corbin Russwin CK4851 entrance/office knob lock is another Grade 1 option.
6) I need the same knob on doors that should not lock with a key. What matches the Falcon W501?
Use a passage or privacy function knob in place of the keyed entrance function the Falcon W501 provides. In Grade 2 cylindrical, the Corbin Russwin CK4410 is a passage/closet knob lock for 1-3/8 inch to 1-3/4 inch doors, the Dexter C2000 passage ball knob covers the same door range non-keyed, and the Dexter C2000 privacy ball knob handles bed and bath openings. The Arrow MK01 and Arrow RK01 are also Grade 2 non-keyed passage knob locks fitting 1-3/8 inch to 1-3/4 inch doors. For an opening with no latch at all, the BEST 6K Series single dummy trim is a Grade 2 medium duty dummy knob.
7) What knob lock do I use instead of a Falcon W501 on a classroom or a stock room door?
Those openings need a different function. For a classroom door keyed from the outside, the Dexter C2000 Series is a Grade 2 keyed classroom ball knob lock for 1-3/8 inch to 1-3/4 inch doors. For a stock room or utility door that stays locked with free egress, the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder. The Falcon W501 is an entrance function, where the outside knob is locked and unlocked by a button or turn rather than staying locked at all times.
8) Which knob lock fits a door thicker than 1-3/4 inches when the Falcon W501 will not?
The Falcon W501 covers doors from 1-3/8 inch to 1-3/4 inch. For a thicker leaf, the Corbin Russwin CK4851 Grade 2 entrance/office cylindrical knob lock takes doors 1-3/8 inch to 2 inch with a conventional cylinder, and the non-keyed Corbin Russwin CK4310 passage/closet knob covers the same 1-3/8 inch to 2 inch range. On the decorative side the Deltana 3381 Egg Knob entry and 6171 Round Knob entry also list 1-3/8 inch to 2 inch.
9) For a multi-family building standardizing on one knob lock, how does the Falcon W501 compare to the Callan Edgewood?
Both are Grade 2 entrance knobsets, and the Callan Roland is another Grade 2 entrance knob offered in US15 satin nickel. Where the Falcon W501 differs for a fleet is the keying program: it accepts an interchangeable core and can be ordered keyed alike across multiple units or keyed different, in a G, C Schlage, E, H, K, L, N or P keyway, and it is UL listed for 3 hour A label fire doors where corridor openings carry a label.
10) What does the entrance function do on a Falcon W501 knob lock?
Entrance function, F86: key operates the outside knob, and the lock is single cylinder, so there is a key outside only. Turn or push the inside control to lock the outside knob; the inside knob always retracts the latch for free egress. This is the function for an office or apartment entry door where staff need to lock behind themselves without a key. If you want an outside knob that stays locked at all times and cannot be left unlocked, a storeroom function is the one to look at instead, such as the Sargent 6G04 Grade 2 storeroom knob lock.
11) What do I have to specify when ordering a Falcon W501 knob lock?
Five things are required on the order: keyway (C Schlage, G, E, H, K, L, N, P, or none if you are buying less cylinder), keying (keyed different, keyed alike, or none for the less cylinder route), latch, strike, plus finish and knob style. A key code field is there if you are matching an existing system. The latch and strike choices are where most mistakes happen, since they have to match the backset and the existing door and frame prep.
12) Is there a lower-cost alternative to the Falcon W501 for a light-duty keyed entry door?
Grade 3 keyed knob locks cover the same entrance function on lighter openings. The Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway that fits 1-3/8 inch to 1-3/4 inch doors, the Pamex FTF Baron is a Grade 3 entrance/office knob lockset over the same door thickness range, and the Callan Canova and Callan Santo are Grade 3 entrance knobsets. The trade is the certification level and the keying system: the Falcon W501 is Grade 2 and takes an interchangeable core, while the BER00 is built around a Kwikset keyway.
13) Will a Baldwin, Emtek, Deltana or Omnia knob work as a substitute for the Falcon W501?
Those are decorative interior knobsets and they answer a different need. The Emtek Arts and Crafts hammered egg knobset and the Emtek Classic Brass Crystal Georgetown and Providence knobs are sold as dummy pairs, the Omnia 434/0 and 442/00 are single dummy latchsets, and the Baldwin Estate 5011 Colonial and Estate 5000 Baltimore are passage and privacy knobs. Deltana offers entry knobs such as the 6901 Portland for 1-3/8 inch to 1-3/4 inch doors and the 6171 Round Knob for 1-3/8 inch to 2 inch doors. None of them is a Grade 2 commercial cylindrical lock with an interchangeable core the way the Falcon W501 is, so on a keyed commercial opening they are not a swap.
14) Is the Sargent 28C knob trim an alternative to a Falcon W501?
No. The Sargent 28C-KNOB is exit device trim with a knob and rose in a classroom function for 1-3/4 inch doors, and the Sargent 78-2875 is an outside knob only in the B design. Trim mounts to an exit device or an existing lock body, not into a bored door prep on its own. The Falcon W501 is a complete cylindrical lock chassis that installs into a bored opening with its own latch and strike. The Imperial USA ED-BKL580 is likewise knob trim in a storeroom function.
15) If I want a keyless knob lock on the opening instead of the Falcon W501, what is available?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, and it fits doors from 1 3/16 inch to 2 inch. It removes the key from the opening entirely, so there is no keyway or core to manage. The Falcon W501 goes the other way, taking a keyed cylinder in G, C Schlage, E, H, K, L, N or P keyways with an interchangeable core that pulls for re-keying, which is what keeps it on a building master key system.
16) What is the difference between the Falcon W501 and the Schlage A170 or D10S knob locks?
Function is the divider. The Schlage A170 is single dummy trim, a Grade 2 heavy duty non-keyed knob for doors 1-3/8 inch to 1-7/8 inch with no latch action at all, and the Schlage D10S is a Grade 1 heavy duty non-keyed passage latch with an Orbit knob that always turns free. The Falcon W501 is keyed with a single cylinder in an entrance function, so it controls access rather than just pulling a door shut.
17) What finishes does the Falcon W501 entry knob come in, and can I match existing hardware?
Eight BHMA 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. Two knob styles are offered, Elite and Hana. For matching a fleet of existing openings, 626 satin chrome is the common commercial finish and 605/606 the brass pairings.
18) Is the Falcon W501 an electronic or access control lock?
No, the W501 is a purely mechanical cylindrical knob lock, key and knob only, with no electrified or credential option. If the opening needs card access or a code, this is the wrong part. A mechanical keyless option in a knob format is the Lockey 3830 combination knob lock, which is passage function with auto-locking and fits doors from 1 3/16 to 2 inches.
