Schlage Residential FC21 HOB 622 KIN – Frequently Asked Questions

1) Do I have to order a specific backset for the Schlage FC21 knob, 2-3/8 or 2-3/4?
No, you order one part either way. The FC21 ships with a dual backset latch that adjusts to fit either a 2-3/8 inch or a 2-3/4 inch backset, which are the two backsets you find in residential bores. That matters on a mixed building where the older doors were drilled at one and the newer ones at the other.
2) How does one Schlage FC21 knob work as both a passage and a privacy lock?
Passage is the default: the knob turns freely from both sides with nothing to lock. To make it a privacy set, you insert the privacy pushbutton on the interior side. After that, pushing the button locks the outside knob, and turning the inside knob releases it. From the outside it opens with a small emergency unlock tool. That means one part number covers your hall and closet doors and your bedroom and bath doors, and you decide which it is at install.
3) Will the Schlage FC21 latch drop into my existing strike, or do I need to replace the strike plate?
The FC21 latch has a 1/2 inch throw with a 1 inch by 2-1/4 inch faceplate and a 1/4 inch radius corner, which is the standard residential prep. It ships with a full lip radius strike measuring 1-5/8 by 2-1/4 inches. If your frame already has a radius corner strike of that size, the new latch lines up with it. If the existing mortise is square cornered, use the supplied strike and square the mortise, or fit a square corner plate.
4) Can I use the Schlage FC21 Hobson knob on a 90 minute fire rated apartment door?
The FC21 is available UL Listed for 90 minute fire door applications, and it carries ANSI/BHMA A156.2-2017 Grade 2 plus ANSI/BHMA A156.39-2015 Residential Grade AAA. Note that the fire listing is an available configuration rather than automatic on every build, so specify the UL listed version when the opening is rated.
5) Does the Schlage FC21 knob take a key? I need to lock a closet that stores tools.
No. The FC21 is a non-keyed set, passage or privacy only. The privacy button is a bathroom style lock that anyone can release from outside with the emergency tool, so it is not security for a storage room. For a keyed or storeroom function you want a different lock entirely, such as the Cal-Royal AG05 Grade 2 storeroom lever with a deadlocking latchbolt, or the Arrow MK33-BD-CS Grade 2 asylum lock in the Schlage C keyway.
6) The Schlage FC21 Hobson does not fit a 2 inch thick door - what passage lock does?
The Schlage FC21 Hobson covers door thicknesses from 1-3/8 inch to 1-3/4 inch. For a thicker door in the same passage function, the Hager 2510 passage cylindrical lever lock is a Grade 2 unit rated 1-3/8 inch to 2 inch, and the Falcon K101 passage cylindrical lock with non-handed levers is a Grade 1 unit rated 1-3/8 inch to 2-1/4 inch with a fire rating. The Arrow GL01 Sierra lever passage lock is Grade 2 and rated 1-3/4 inch to 2 inch, so it starts where the FC21 range ends. All three are levers rather than knobs, and none of them offer the FC21 pushbutton privacy conversion.
7) What is a heavier duty alternative to the Schlage FC21 for a passage door in a high traffic corridor?
The Schlage FC21 Hobson is a Grade 2 cylindrical lock built for residential use. Where the traffic calls for a heavier unit in the same passage function, the Falcon T101 is a Grade 1 heavy duty cylindrical passage lever lock, the Falcon K101 is a Grade 1 passage cylindrical lock with non-handed levers and a fire rating, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever lock, also fire rated, for doors 1-3/4 inch to 2 inch. The Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. All are passage only, so the privacy side of the FC21 is not carried over.
8) What is the closest equivalent to the Schlage FC21 Hobson knob if the door needs a lever instead of a knob?
The Schlage FC21 Hobson is a knob-style cylindrical non-keyed lock in the passage/privacy function. For a lever on the same style of interior door, the Falcon B101 is a Grade 2 cylindrical passage lever lock with a non-handed design, and the Accentra 5301LN Augusta is a Grade 2 cylindrical lever lock in the passage/closet function. Both carry the same Grade 2 rating as the FC21. The difference in operation matters: the FC21 defaults to passage and converts to privacy when the pushbutton is inserted on the interior side, while the B101 and 5301LN are passage only, so a bedroom or bathroom door that needs to latch shut is not covered by them.
9) What knob lock should be used for a bathroom door that only needs privacy, not passage?
The Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed, in the privacy/bed/bath function, and it carries a fire rating. The Schlage FC21 Hobson covers the same door differently: it ships as passage and becomes privacy only once the pushbutton is inserted on the interior side, and it can be opened from outside with a small emergency unlock tool. A buyer who wants privacy fixed from the box, with no conversion step in the field, is looking at the MK02-TA; a buyer stocking one part for both hall doors and bath doors is looking at the FC21.
10) What looks like a substitute for the Schlage FC21 Hobson but will not latch a door?
Dummy trim is the trap. The BEST 7KC single dummy trim cylindrical lever lock is Grade 2 medium duty, the BEST 9K 1DT single dummy trim is Grade 1 heavy duty, the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever lock, and the Callan Bentley is a Grade 2 dummy lever. All are dummy function: fixed trim with no latch and no privacy. The Schlage FC21 Hobson is a passage and privacy cylindrical lock with a spring latch and full lip radius strike, so it actually holds the door closed. Dummy trim belongs on an inactive leaf or a closet door held by a ball catch, not on a bedroom or bath door.
11) What should be used instead of the Schlage FC21 Hobson on a unit entry door that has to be keyed?
The Schlage FC21 Hobson is non-keyed, so it does not secure an entry. For a keyed opening, the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle for 1-3/8 inch to 2 inch doors, the Falcon B511CP6D is a Grade 2 cylindrical lever lock in the entry/office function, and the Cal-Royal AG00 entrance lever is a Grade 2 with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. The Arrow HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for 1-3/8 inch to 1-3/4 inch doors, which keeps the knob shape on the entry while the FC21 handles the interior doors.
12) Is the Schlage FC21 knob handed? I do not know which way the door swings.
It is non-handed, so one FC21 works on a left or right hand door with no reversing step. Order without recording swing on your takeoff.
13) What finishes and rose styles does the Schlage FC21 Hobson knob come in?
Five finishes: 608 Satin Brass, 618 Polished Nickel, 619 Satin Nickel, 622 Matte Black and 716 Aged Bronze. Each pairs with a choice of seven rose designs, Camelot, Century, Collins, Kinsler, Dalton, Greene and Howe, so the same knob can be matched to trim already in the building. Pick the rose to match the other openings and the finish to match the rest of the hardware.
14) My residents need lever handles for accessibility. Is there a passage lever that fits the same doors as the Schlage FC21?
The FC21 is a knob, so it will not satisfy a lever requirement. For the same 1-3/8 to 1-3/4 inch door range in a Grade 2 passage lever, the Kwikset 200BRNL Breton passage lever covers 1-3/8 to 1-3/4 inch doors at Grade 3, and the Cal-Royal AG00 lever covers the same thickness range. In Grade 2, the Falcon B101 and the Accentra 5301LN Augusta are both non-keyed passage cylindrical levers.
15) What comes in the box with the Schlage FC21 knob, and what do I need to supply?
Both knobs, the roses, the dual option spring latch (16-600, available round faceplate or drive-in) and the 10-027 full lip radius strike are included, along with the privacy pushbutton you insert if you want the privacy function. You supply the door prep and a screwdriver, which is the only tool the three step install calls for. There is no wiring; it is a mechanical lock with no electronic component.
16) Is there a lighter duty passage and privacy pair that fits the same 1-3/8 to 1-3/4 inch doors as the Schlage FC21 Hobson?
The Kwikset 200BRNL Breton passage lever set is a Grade 3 passage/hall/closet lock rated for 1-3/8 inch to 1-3/4 inch doors, and the Kwikset 300BRNL Breton privacy lever set is a Grade 3 privacy/bed/bath lock over the same 1-3/8 inch to 1-3/4 inch range. Between them they cover the same two doors the Schlage FC21 Hobson covers with one part number, over the same 1-3/8 inch to 1-3/4 inch door thickness. The trade is that the Kwikset pair is Grade 3 against the FC21 Grade 2, they are levers rather than knobs, and the function is fixed at purchase rather than converted with a pushbutton in the field.
17) Can a Baldwin Estate 5103 be used in place of a Schlage FC21 Hobson?
The Baldwin Estate 5103 with the 5048 rose is sold as separate function-specific parts: a passage lever, a privacy lever, and left hand and right hand half dummy levers. That means the function is chosen at the order, one part number per door type. The Schlage FC21 Hobson is a single non-handed knob that ships as passage and converts to privacy with a pushbutton on the interior side, so one part number covers a hall door and a bath door. A buyer matching an existing Baldwin Estate opening picks the 5103 in the matching function; a buyer standardizing one SKU across mixed interior doors is served by the FC21.
18) Is a storeroom or classroom lock a substitute for the Schlage FC21 Hobson on an interior door?
No. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever, and the Dexter C1000 classroom cylindrical lever lock is a Grade 1 keyed, clutching lock for 1-3/8 inch to 1-3/4 inch doors. All three are keyed functions where the outside side stays locked or is controlled by key. The Schlage FC21 Hobson is non-keyed: it is free-turning passage until the interior pushbutton is inserted, and it releases when the inside knob is turned, which is what a bedroom, bath, hall or closet door needs.
19) Should I use the round faceplate latch or the drive-in latch on the Schlage FC21?
Both ship with the lock. Use the faceplate version when the door edge is mortised for a 1 inch by 2-1/4 inch plate, which is the case on almost any door that had a previous lockset. Use the circular drive-in on a fresh bore with no edge mortise, common on new prehung slabs, since it seats in the 1 inch latch housing bore with no chiseling.
20) I have Schlage F Series knobs on the rest of the building. Will the FC21 Hobson match them?
The FC21 is part of Schlage's F Series residential line, so it shares that family's trim language and finish codes, and the seven rose options let you get closer to whatever is already hanging. Matching is by finish code and rose design rather than by model, so pull the finish number off an existing knob (608, 618, 619, 622 or 716) and order the same one.
21) Which passage locks match a Schlage FC21 Hobson in satin brass on other doors?
The Schlage FC21 Hobson is offered in 608 satin brass. Among passage locks, the Bravura Miramar with round trim passage leverset is a Grade 2 unit specified in US4 satin brass. It is a lever with round trim rather than a knob, so the shape reads differently on the door even where the finish family lines up. If the goal is a consistent knob across a run of interior doors, the FC21 itself carries satin brass across the Camelot, Century, Collins and Kinsler rose designs.
22) What Grade 2 passage lock is the closest match to the Schlage FC21 Hobson for a closet door that never needs privacy?
For a closet or hall door where privacy is never used, the Accentra 4601LN is a Grade 2 passage cylindrical lever lock with Augusta trim, the Accentra 5301LN Augusta is a Grade 2 cylindrical lever lock in the passage/closet function, and the Bravura Atlanta, Orlando and Tampa round and square trim passage leversets are Grade 2 passage units. Each carries the same Grade 2 rating as the Schlage FC21 Hobson. The FC21 pushbutton simply stays out of the interior side on a closet door, which is why it also fits the same opening if a single knob across all the interior doors is preferred.
