Schlage Residential FC21 GEO 608 ALD – Frequently Asked Questions

1) Do I need to know the backset before ordering the Schlage FC21 knob?
No. The FC21 ships with a dual backset latch that fits either a 2-3/8 inch or 2-3/4 inch backset, so you set it on site to match the cross bore you already have. That matters on a retrofit where you cannot see the existing prep until the old lock is off, and on a mixed building where some doors were bored one way and some the other.
2) Is the Schlage FC21 a passage knob or a privacy knob?
Both, and you decide which at install. Out of the box the FC21 works as a passage set with no locking. Inserting the privacy pushbutton on the interior side converts it to privacy for a bedroom or bath, and it can still be opened from the outside with a small emergency unlock tool. One part number covers hall, closet, bed and bath, which is why it works well as a single stocked item across a building.
3) Is the Schlage FC21 knob handed, and does it need a left or right hand version?
Non-handed. The FC21 uses a universal latch, so the same lock goes on a left hand or right hand door with no reversing and no separate part number. For a property manager buying a case of these for a turn, that means one line item covers every door regardless of swing.
4) Will the Schlage FC21 latch line up with the strike plate already in my door frame?
The FC21 comes with a 1-5/8 by 2-1/4 inch full lip radius corner strike (part 10-027) and a 1 by 2-1/4 inch latch face with a 1/4 inch radius corner and 1/2 inch throw. If the existing frame is cut for a radius corner strike of that size, the supplied strike drops straight in. If your frame has a square corner mortise, the radius strike will leave a gap at the corners and the frame needs to be filed or a square strike substituted. The 1 inch latch housing diameter matches a standard 1 inch edge bore.
5) Can I use the Schlage FC21 knob on a rated fire door?
The FC21 is available UL Listed for 90 minute fire door applications. If the opening is rated, you need the UL Listed version specified when you order, not just any FC21. For a corridor or stair door in a multi-family building, that distinction is the one that passes or fails inspection.
6) I have 2 inch thick doors, will the Schlage FC21 work?
No. The FC21 tops out at 1-3/4 inches, so a 2 inch door is outside its range. For thicker doors, the Hager 2510 Grade 2 passage lever covers 1-3/8 to 2 inches, the Arrow GL01 Grade 2 passage covers 1-3/4 to 2 inches, and the Falcon K101 Grade 1 passage covers 1-3/8 to 2-1/4 inches. Measure the actual door, not the frame, before you order.
7) What is the closest equivalent to the Schlage FC21 Georgian knob if I want a lever instead of a knob on an interior passage door?
The Schlage FC21 Georgian is a Grade 2 non-keyed cylindrical lock with a knob handle in the passage/privacy function. For the same passage function in a Grade 2 cylindrical lever, 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 passage/closet function. Both carry the same Grade 2 rating as the FC21; the difference is the handle, and a lever is the usual choice where ADA-style operation without grasping is wanted.
8) The FC21 knob only fits doors up to 1-3/4 inch - what passage lock works on a 2 inch thick door?
The Georgian FC21 covers a door thickness range of 1-3/8 inch to 1-3/4 inch. For a thicker door, the Corbin Russwin CL3110 passage/closet lock covers 1-3/4 inch to 2 inch, the Hager 2510 passage lever covers 1-3/8 inch to 2 inch, and the Falcon K101 passage lock covers 1-3/8 inch to 2-1/4 inch. All three are lever locks rather than knobs, so confirm the trim style suits the opening before ordering.
9) For a fire-rated interior door, can I use the Georgian FC21 or is there a better-suited passage lock?
The Georgian FC21 is available UL Listed for 90 minute fire door applications. Among comparable passage locks carrying a fire rating, the Falcon K101 is a Grade 1 heavy duty passage lock that is fire rated for doors 1-3/8 inch to 2-1/4 inch, and the Corbin Russwin CL3110 passage/closet is a Grade 1 fire rated lever for 1-3/4 inch to 2 inch doors. The FC21 is the knob option at Grade 2; those two are Grade 1 levers with wider door ranges.
10) Can I use a dummy trim in place of the Georgian FC21 on a closet door?
No - the two do different jobs. The Georgian FC21 is a working passage lock with a latch that retracts when the knob is turned. A dummy such as the BEST 7KC single dummy trim, the Accentra 455LN Augusta single dummy, or the Baldwin Estate 5103 half dummy is fixed trim with no latch at all, meant for an inactive leaf or a door held closed by a catch. If the closet door needs to latch, the FC21 passage function is the correct part.
11) What grade is the Schlage FC21 Georgian knob and is it strong enough for apartment turns?
Grade 2 under ANSI/BHMA A156.2-2017, plus Residential Grade AAA under A156.39-2015. Grade 2 is the middle commercial tier and sits above the Grade 3 residential sets like the Kwikset 200BRNL Breton passage lever, so it holds up better on apartment and condo interior doors that get cycled hard between tenants. For a heavy traffic commercial corridor you would step up to a Grade 1 cylindrical, such as the Falcon K101 passage.
12) Should I use a knob like the Schlage FC21 or a lever set on interior doors?
A knob is the traditional residential look and the Georgian is a round knob design. Where you need a lever, either for ADA-style accessibility on an accessible unit or because the spec calls for one, a knob will not satisfy it and you want a passage lever instead. Comparable passage levers include the Falcon B101 Grade 2 cylindrical passage and the Hager 2510 Grade 2 passage, which fits 1-3/8 to 2 inch doors. Levers also work better for anyone carrying things through a door all day.
13) What tools do I need to install a Schlage FC21 knob on an already bored door?
A screwdriver. On a door that is already bored to standard cylindrical prep, the FC21 goes in as a three-step install using the included universal latch and strike, with no handing to sort out and no special driver. On a new door you drill to the template first and set the latch to 2-3/8 or 2-3/4 inch depending on the backset you bored.
14) What else could I buy instead of the Schlage FC21 for passage function on interior doors?
Straight Grade 2 passage alternatives include the Falcon B101 cylindrical passage lever and the Accentra 5301LN Augusta from the 5300 Series. For a lower-cost residential set, the Kwikset 200BRNL Breton passage is Grade 3 and covers the same 1-3/8 to 1-3/4 inch door range. Stepping up, the Falcon K101 is Grade 1 heavy duty, fire rated, and spans 1-3/8 to 2-1/4 inch doors. The thing to watch: none of those are knobs and none of them convert to privacy with a pushbutton the way the FC21 does, so if you need one part number covering both hall doors and bedrooms, they are not a like-for-like swap.
15) Can a Schlage FC21 knob be locked out or held open, and can maintenance get in if a tenant locks the bathroom?
Yes on both counts, and it is the reason this set gets specified for rentals. Left as passage it never locks. Once the privacy pushbutton is fitted, a tenant can lock the interior side, and maintenance can release it from the corridor side with a small emergency unlock tool. There is no key involved, so nothing to rekey at turnover.
16) Does the Schlage FC21 come with the latch and strike or do I order them separately?
Both are included. You get the 16-600 spring latch, which is the dual option round and drive-in style, and the 10-027 full lip radius strike at 2-1/4 by 1-5/8 inches. The drive-in option matters on a door with no latch face mortise, since you can drive the latch straight into a 1 inch edge bore without routing a faceplate pocket.
17) I need a lock for a utility or institutional room, not a bedroom - what takes the place of the Georgian FC21 there?
The Georgian FC21 handles passage and privacy on interior doors and is not intended for a secured room. For utility and institutional openings, the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum function cylindrical lock with a ball knob and a conventional cylinder in the Schlage C keyway, and the Dexter C1000 asylum F87 is a Grade 1 lock for doors 1-3/8 inch to 2 inch. For a storeroom door, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt over the same 1-3/8 inch to 1-3/4 inch door range as the FC21.
18) What is a knob-style alternative to the Schlage Georgian FC21 for a bed or bath privacy door?
The Georgian FC21 ships as passage by default and converts to privacy when the pushbutton is inserted on the interior side. If a dedicated privacy knob is preferred, the Arrow MK02-TA is a privacy function cylindrical lock with a Tudor knob and is fire rated, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever set for doors 1-3/8 inch to 1-3/4 inch. The Arrow MK02-TA fits doors 1-3/4 inch to 2 inch, so check the door thickness before swapping.
19) What is a simpler passage handle set than the Schlage Georgian FC21 for interior doors in a rental unit?
The Georgian FC21 is a Grade 2 knob covering doors 1-3/8 inch to 1-3/4 inch. For a lighter-duty interior passage handle over the same door range, the Kwikset 200BRNL Breton is a Grade 3 passage lever set for 1-3/8 inch to 1-3/4 inch doors, and the Callan Asheville is a Grade 3 passage leverset. Both sit at Grade 3 rather than Grade 2, which is the trade for the simpler set.
20) Which passage locks match the Georgian FC21 on grade if I want a different trim look across a building?
The Georgian FC21 carries a Grade 2 rating in the passage/hall/closet function. Other Grade 2 passage sets in that same function include the Accentra 4601LN with Augusta trim, the Arrow GL01 with a Sierra lever, the Bravura Atlanta, Orlando and Tampa passage leversets, the Design Hardware J75 flat lever, and the Hager 2510 with the Withnell design. Each is Grade 2 like the FC21, so the choice among them is trim style and door range - the Arrow GL01 covers 1-3/4 inch to 2 inch doors and the Design Hardware J75 is for 1-3/4 inch doors, while the FC21 covers 1-3/8 inch to 1-3/4 inch.
21) Is there a keypad option that replaces the Georgian FC21 knob on an interior door?
The Georgian FC21 is a mechanical, non-electronic lock. For coded entry on a similar opening, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function and fits doors 1-1/8 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. The Lockey 1150 needs no power; the Delaney LP250 is electronic, so plan for batteries and a lever rather than a knob.
22) Does the Accentra 107S Schlage cylinder adapter kit let me key the Georgian FC21?
No. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, so it belongs to that hardware line, not to the Schlage F Series. The Georgian FC21 is a non-keyed passage and privacy lock with no cylinder to adapt - it opens from outside only with a small emergency unlock tool. A keyed opening needs a keyed lockset ordered in place of the FC21, not an adapter.
23) What finishes and rose styles does the Schlage FC21 Georgian knob come in?
Five finishes: 608 Satin Brass, 619 Satin Nickel, 622 Matte Black, 625 Bright Chrome and 716 Aged Bronze. Each pairs with three rose designs, Alden, Camelot and Collins, so the same knob can be matched to trim that is already on the other doors. If you are standardizing a building, pick the rose first since it is the part that reads visually from down the hall, then hold the finish across every opening.
24) What is the Schlage FC21 knob made of and will it hold up in a bathroom?
Stainless steel construction, which is the reason it takes humidity on a bathroom door better than a plated pot metal set. Combined with the privacy pushbutton conversion, that makes it a common choice for bed and bath doors in apartments and condos.
