Falcon W571LD ELI 626 – Frequently Asked Questions

1) What does the dormitory/corridor function on the Falcon W571 actually do?
The W571 is an F86 dormitory/corridor function. Outside knob is locked or unlocked by key only, and the inside knob always retracts the latch for free egress. That is why it suits corridor and dorm room doors where you want the door to stay locked behind you but never trap anyone inside. If you want a lock that stays locked outside at all times and cannot be left unlocked, a storeroom function is the better call, like the Sargent 6G04 Grade 2 storeroom knob lock.
2) Will the Falcon W571 latch into the strike already in my frame?
Depends on what is cut into the jamb. The standard strike is an ANSI 1-1/4 x 4-7/8 curved lip (part 30-148 with a 1-3/8 inch lip), which drops into a standard ANSI frame prep. If your frame has a smaller cutout, three other strikes are selectable: 30-149 T-strike at 1-1/8 x 2-3/4, and full lip strikes 30-150 radius corner and 30-151 square corner, both 1-5/8 x 2-1/4 with a 1 inch lip. The latchbolt throws 1/2 inch, so the strike lip has to be set for that engagement.
3) Do I have to order the Falcon W571 handed for a left or right door?
No handing to specify. The W571 is non-handed and does not need field disassembly to re-hand, so one part number covers left and right swings. For a property manager stocking spares across a building, that means a single lock on the shelf fits any opening.
4) Can I put the Falcon W571 on a fire rated door?
Yes. The W571 is UL Listed for 3 hour A label fire door assemblies. The latch is a deadlatching latch, which is what a fire door needs to stay positively latched under pressure.
5) Can the Falcon W571 be keyed into my existing Schlage key system?
Yes, if your system runs the Schlage C keyway. The W571 keyway is a selectable option and C Schlage is on the list, along with Falcon G, E, H, K, L, N and P. Keying choices are keyed different or keyed alike, and if you are matching an existing system you supply the key code on the order. The default keyway on the base spec is G.
6) Can I order the Falcon W571 without a cylinder so I can install my own interchangeable core?
Yes. Three cylinder configurations are offered: a 6 pin conventional cylinder, less 6 pin cylinder, and less small format interchangeable core. If your facility is standardized on SFIC, order the less SFIC version and drop in your own cores. It also accepts interchangeable cores from multiple manufacturers, which is what makes rekeying a whole building practical without pulling chassis.
7) Is a Grade 2 knob lock enough for a dorm or apartment corridor, or should I go Grade 1?
Grade 2, medium duty, is what the W571 is built and certified to under ANSI/BHMA A156.2 Series 4000, and it is aimed at low to moderate traffic commercial openings: dorm rooms, apartment entries, offices, retail back-of-house. On a high cycle opening, a main corridor, a school, a busy public entrance, step up to Grade 1 heavy duty. The BEST 8K Series is a Grade 1 heavy duty knob lock, and the Sargent 8XG04 is a Grade 1 heavy duty knob lock on a 2-3/4 inch backset.
8) I need a keyed knob lock for an apartment or office entry, not a corridor lock. What is the difference and what should I buy?
The W571 dormitory/corridor function locks and unlocks the outside knob by key only, with no inside button, so a tenant cannot leave it unlocked from inside. An entrance/office function does have inside control and lets the occupant lock or unlock without a key, which is what most apartment and office doors call for. In Grade 2 keyed knobs, the Corbin Russwin CK4851 entrance/office and the Dexter C2000 entry/office ball knob both cover that function; the Dexter is rated for 1-3/8 to 1-3/4 inch doors, the Corbin Russwin for 1-3/8 to 2 inch.
9) What is the closest cross-brand equivalent to the Falcon W571 knob lock for a dormitory corridor door?
The Falcon W571 is a Grade 2 cylindrical knob lock with dormitory/corridor function, a 2-3/4 inch backset and single-cylinder keying. The nearest peers by grade and keyed knob format are the Sargent 6G04, a Grade 2 standard-duty storeroom/closet knob lock with a single cylinder in the 6 Line Series, and the Corbin Russwin CK4851 Grade 2 entrance/office cylindrical lock with a Global knob and conventional cylinder. Both are keyed cylindrical knob locks in the same grade class, but their functions differ from dormitory/corridor: the 6G04 is storeroom, where the outside knob stays locked and the key retracts the latch, and the CK4851 is entrance/office, where the outside knob is locked and unlocked by a pushbutton or turn rather than by the key alone. Match the function to how the corridor door is meant to behave before substituting.
10) What is the heavy-duty step up from a Grade 2 dormitory knob lock for a high-traffic corridor?
The Falcon W571 is a Grade 2, medium-duty cylindrical knob lock. Where the traffic count pushes past medium duty, the Grade 1 keyed knob peers are the Sargent 8XG04, a heavy-duty Grade 1 storeroom/closet single-cylinder knob lock with a 2-3/4 inch backset in the 8X Line Series, and the BEST 8K Series 8K-AB, a heavy-duty Grade 1 entrance-function single-cylinder knob lock. The 8XG04 shares the W571's 2-3/4 inch backset, so an existing bore and strike location carries over. Both are storeroom and entrance functions respectively, not dormitory/corridor, so confirm the required latching behavior before specifying either.
11) What knob lock should I use instead of the Falcon W571 on a classroom door?
The Falcon W571 carries dormitory/corridor function, where the outside knob is locked and unlocked from the inside. A classroom door, where the outside knob is locked and unlocked only by key from the corridor side, calls for a classroom-function lock instead: the Dexter C2000 Grade 2 classroom cylindrical ball knob lock, non-clutching and keyed, fitting 1-3/8 inch to 1-3/4 inch doors, is the Grade 2 knob peer for that opening. The two share grade and door thickness range but not the locking sequence, which is the whole reason a classroom is specified separately.
12) Is a Grade 3 keyed entry knob a valid substitute for a Falcon W571 on a commercial corridor door?
The Falcon W571 is a Grade 2 commercial cylindrical lock certified to ANSI/BHMA A156.2 Series 4000 Grade 2 and UL listed for 3-hour A label fire door assemblies. Grade 3 keyed knobs such as the Cal-Royal BER00 entrance/office knob lock with a Kwikset keyway, the Pamex FTF Baron entrance/office lockset, and the Kwikset 400P-CP Polo keyed entry knob sit a grade below that, and all three are entrance/office function rather than dormitory/corridor. They fit the same 1-3/8 inch to 1-3/4 inch doors, so they will physically hang in the same opening, but a corridor specified to Grade 2 with a fire label requirement is a different specification than these meet.
13) Which knob products look like a Falcon W571 replacement but will not lock a door?
The Falcon W571 is a keyed single-cylinder lock with a deadlatch and a 1/2 inch throw stainless latch bolt. Several knob products share the same knob-and-rose appearance and secure nothing. Dummy trim such as the Schlage A170 Grade 2 single dummy, the BEST 6K single dummy trim and the Cal-Royal BA40 dummy knob is surface-mounted trim with no latch at all, used on the inactive leaf of a pair. Privacy knobs such as the Dexter C2000 privacy ball knob and the Pamex FTF Baron privacy lockset lock from the inside only with no key outside. Passage knobs such as the Kwikset 200P Polo latch but never lock. None of these will hold a corridor door secure the way a keyed dormitory/corridor lock does.
14) What knob lock handles a door thicker than 1-3/4 inches when the Falcon W571 will not?
The Falcon W571 covers door thickness from 1-3/8 inches to 1-3/4 inches. For a thicker leaf, the Corbin Russwin CK4851 Grade 2 entrance/office cylindrical lock with Global knob and conventional cylinder is rated 1-3/8 inches to 2 inches, and the non-keyed Corbin Russwin CK4310 Grade 1 passage/closet lock covers the same 1-3/8 inch to 2 inch range. Both are entrance/office and passage functions rather than dormitory/corridor, so measure the leaf first and then match the function the opening requires.
15) What finishes does the Falcon W571 come in, and can I match the other doors in the 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. Those are BHMA finish numbers, so if the existing hardware on your other openings is specified as 626 or 613, ask for the same number and it will match across brands rather than eyeballing a color name. Two knob designs are offered as well, Elite and Hana.
16) What do I need to specify when ordering a Falcon W571 knob lock?
Five things get selected on the order: keyway (C Schlage, G, E, H, K, L, N, P, or none for a less-cylinder build), keying (keyed different, keyed alike, or none), the latch (2-3/4 or 2-3/8 backset, square or radius corner face), the strike, and the finish plus knob design. Add a key code if you are matching an existing keyed-alike group. Getting the latch backset and the strike right against what is already cut in the door and frame is where most wrong orders happen.
17) If the door does not need to be keyed, what non-keyed knob lock takes the place of a Falcon W571?
The Falcon W571 is keyed with a single cylinder. On the hall, closet and connector doors in the same run that carry no key, the Grade 2 passage peers are the Corbin Russwin CK4410 passage/closet cylindrical lock with a Global knob, non-keyed, rated for 1-3/8 inch to 1-3/4 inch doors, the Dexter C2000 passage cylindrical ball knob lock, non-clutching and non-keyed, also 1-3/8 inch to 1-3/4 inch, and the Arrow MK01 passage knob lock. All three cover the same 1-3/8 inch to 1-3/4 inch thickness range the W571 does, so one door prep serves both the keyed and non-keyed doors on the same floor.
18) Can I put a Falcon W571 on a door that already has an exit device?
The Falcon W571 is a complete cylindrical lockset with its own chassis, deadlatch and strike, bored into the door. A door fitted with an exit device takes trim rather than a lockset: the Sargent 28C-KNOB exit device trim with knob and rose in classroom function for 1-3/4 inch doors, the Sargent 78-2875 outside knob only with B design in the 7800 Series, and the Imperial USA ED-BKL580 knob trim in storeroom function for the ED-500 Series all mount to the exit device and operate its latch. These are outside trim, not standalone locks, and are not interchangeable with a bored cylindrical lockset in either direction.
19) What is the difference between the Falcon W571 and a residential knob set that looks similar?
The Falcon W571 is a commercial cylindrical knob lock, Grade 2, non-handed, with a 2-3/4 inch backset and an ANSI 1-1/4 inch by 4-7/8 inch curved lip strike. Residential and decorative knob sets are built to a different pattern: the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 inch to 1-3/4 inch doors, the Baldwin Estate 5000 Baltimore passage knob uses a 2-3/8 inch backset with a full lip strike, and the Emtek porcelain knobs are supplied as two knobs per set on a threaded rod. The ANSI strike prep and 2-3/4 inch backset on the W571 is the standard commercial frame prep; the residential sets above are built around a 2-3/8 inch backset or adjustable latches with round corner and full lip strikes.
20) Which Grade 2 knob locks pair with the Falcon W571 to standardize a multi-family building on one grade?
Standardizing a building means matching grade across every function on the floor. The Falcon W571 covers the keyed dormitory/corridor openings at Grade 2. The Grade 2 peers filling the other functions are the Dexter C2000 series, which spans entry/office, classroom, privacy and passage ball knob locks all at Grade 2 for 1-3/8 inch to 1-3/4 inch doors; the Sargent 6G04 Grade 2 storeroom/closet knob for utility and mechanical rooms; the Corbin Russwin CK4410 Grade 2 passage/closet for halls; and the Schlage A170 Grade 2 single dummy for inactive leaves. Building the schedule from one grade keeps the durability class consistent across the whole door count.
21) Is a keyless combination knob lock an alternative to the Falcon W571 on a corridor door?
The Falcon W571 is a mechanical keyed lock, not electronic, with a single cylinder and a choice of conventional 6-pin or small format interchangeable core preparation. Where the goal is removing keys from circulation entirely, the Lockey 3830 mechanical keyless combination knob lock with auto-locking passage function fits doors from 1 3/16 inches to 2 inches and opens on a pushbutton code rather than a key. The tradeoff is the keying system: the W571 accepts an interchangeable core and can be keyed alike across a set of doors, while a combination lock is managed by changing codes at each door instead.
22) Is there an electronic or access control version of the Falcon W571?
No. The W571 is a mechanical key-operated cylindrical lock with a single cylinder, no electrification option. If the opening needs credential access or audit trail, it is a different product entirely, not an option on this lock.
23) Does the Falcon W571 come with the latch and strike, or do I order those separately?
Both are included and both are chosen as part of the order. Every W571 build takes one latch and one strike selection, so the lock arrives complete with the deadlatch and strike plate plus combination screws that work in wood or hollow metal frames. No separate line items needed to finish the install.
24) What is the Grade 1 non-keyed knob lock that matches the Falcon W571 in build class?
The Falcon W571 is a Grade 2 medium-duty keyed knob lock. For openings on the same run that need no key but do need heavy-duty build, the Schlage D10S passage latch is a Grade 1 heavy-duty cylindrical non-keyed knob lock with an Orbit knob in the D Series, and the Corbin Russwin CK4310 is a Grade 1 passage/closet non-keyed cylindrical lock with a Global knob for 1-3/8 inch to 2 inch doors. Both are passage function, meaning the knob always turns and the door never locks, which is the difference from the keyed dormitory/corridor behavior of the W571.
