Schlage Residential FC21ALXCAM619CYBCAM – Frequently Asked Questions

1) Will the Schlage FC21 Alexandria knob with Clybourn lever fit a 1-3/8 inch interior door?
Yes. The FC21 covers door thicknesses from 1-3/8 inches to 1-3/4 inches, so it drops onto both older 1-3/8 inch interior doors and standard 1-3/4 inch slabs without a spacer kit.
2) Do I need to know the backset before ordering the Schlage FC21?
No. The FC21 ships with a dual backset latch that adjusts to either a 2-3/8 inch or a 2-3/4 inch backset, which are the two bore centers you will find on residential doors. Measure only if you want to confirm the hole is one of those two.
3) Is the Schlage FC21 a passage lock or a privacy lock?
Both, and you decide at install. Out of the box it works as passage, latching without locking. Insert the privacy pushbutton on the interior side and it becomes a bed/bath privacy lock. If somebody locks themselves in, the outside side opens with a small emergency unlock tool.
4) Will the FC21 latch into the strike plate already in my jamb?
The FC21 latch is a 1 x 2-1/4 inch faceplate with 1/4 inch radius corners, 1 inch housing diameter and a 1/2 inch throw, and it comes with a 10-027 full lip radius strike measuring 2-1/4 x 1-5/8 inches. If your existing strike is a radius corner residential strike of that size, the latch will engage it; square corner or T-strike preps will need the new strike mortised in.
5) Is the Schlage FC21 strong enough for apartment turns, or should I use a commercial lever?
The FC21 is certified ANSI/BHMA A156.2-2017 Grade 2 and A156.39-2015 Residential Grade AAA on a stainless steel substrate, which suits apartment and condo interior doors, guest rooms and senior living private rooms. For corridor or high traffic openings in a commercial building, step up to a Grade 1 cylindrical passage lever like the Falcon K101, which covers 1-3/8 to 2-1/4 inch doors and is fire rated, or the Dexter C1000 Grade 1 passage lever for 1-3/8 to 1-3/4 inch doors.
6) The FC21 is non-keyed. What takes its place on a door that needs a key?
The FC21 is non-keyed with passage as its default function. For keyed openings on residential-range doors, the Cal-Royal AG00 is a Grade 2 entrance lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt across the same door range.
7) If the door is in a high-traffic commercial corridor rather than a residence, what should be used instead?
The FC21 is a residential Grade 2 lock. For commercial traffic, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with a fire rating and a 1-3/8 inch to 2-1/4 inch door thickness range, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever lock, also fire rated, for 1-3/4 inch to 2 inch doors.
8) Will an Arrow GL01 passage lever fit the same 1-3/8 inch door the FC21 fits?
No. The Arrow GL01 is a Grade 2 non-keyed Sierra lever passage lock rated for 1-3/4 inch to 2 inch doors, so it does not cover thin 1-3/8 inch leaves. The Schlage FC21 covers 1-3/8 inch to 1-3/4 inch. For a thinner door in a Grade 2 lever passage set, the Hager 2510 Withnell passage lever covers 1-3/8 inch to 2 inch.
9) Is there a Grade 1 passage lever that still fits 1-3/8 inch doors like the FC21?
Yes. The Dexter C1000 Grade 1 passage cylindrical lever lock is non-keyed with clutching and covers 1-3/8 inch to 1-3/4 inch doors, the same range the Schlage FC21 covers. The Falcon K101 Grade 1 heavy duty passage lock spans 1-3/8 inch to 2-1/4 inch if thicker leaves are also in the job.
10) Does the FC21 come handed, or do I have to order left and right?
Non-handed. One part number works on left or right hand doors, so property managers stocking spares only need to carry a single SKU per finish and rose.
11) What finishes and rose designs can I get on the Alexandria knob by Clybourn lever set?
Two finishes, 619 Satin Nickel and 622 Matte Black. The knob side and the lever side each take a rose chosen independently from Camelot, Century, Collins or Kinsler, so you can match the knob rose to the lever rose or mix them across the door.
12) Can I use the FC21 on a 90 minute fire rated door?
A UL Listed 90 minute fire door version of the FC21 is available, so it can go on a rated opening when you specify that option. If you need a lever set where fire rating is carried on the standard product, the Corbin Russwin CL3110 Grade 1 passage lever and the Falcon K101 Grade 1 passage lock are both listed as fire rated.
13) Do I need a special latch for a door with no existing bore, or can I drive it in?
The FC21 ships the 16-600 spring latch, which is a dual option unit giving you both the round faceplate and a drive-in collar. On a drilled door with no latch mortise you can use the drive-in; on a prepped door you screw the faceplate on. No separate latch purchase either way.
14) I want a matching lever on both sides instead of a glass knob. What should I order?
The FC21 configuration is specifically a knob on one side and a lever on the other, Alexandria glass knob by Clybourn lever. For a lever on both faces in a passage function, look at the Accentra 5301LN Augusta Grade 2 cylindrical passage lever, the Falcon B101 Grade 2 non-handed passage lever, or the Hager 2510 Grade 2 passage lever for 1-3/8 to 2 inch doors.
15) What is the difference between the FC21 and a keypad leverset for a rental unit?
The FC21 is a mechanical, non-electronic lock with no keypad. Code-entry alternatives include the Lockey 1150 heavy duty mechanical keypad lever set with double combination in passage function for 1-1/8 inch to 2 inch doors, the Delaney LP250 Grade 2 electronic keypad leverlock, and the Emtek Classic keypad leverset.
16) Is the Kwikset 200BRNL Breton a substitute for the Schlage FC21?
It covers the same opening type but not the same rating. The Kwikset 200BRNL RDT Breton is a Grade 3 passage lever for 1-3/8 to 1-3/4 inch doors, matching the FC21 door thickness range, while the FC21 is Grade 2 and converts from passage to privacy with a pushbutton. If privacy is needed from the Kwikset line, the 300BRNL Breton is the Grade 3 privacy lever for the same door range.
17) What should I order for a closet or double door where the lever does not need to operate a latch?
The FC21 is a functioning cylindrical lock with a latch and strike, so it is not the right part for a non-operating leaf. Dummy trim options include the BEST 7KC single dummy trim cylindrical lever in Grade 2, the BEST 9K 1DT single dummy in Grade 1 heavy duty, and the Emtek Arts and Crafts dummy pair.
18) What is a dedicated privacy lock alternative if I do not want a passage set converted with a pushbutton?
The FC21 ships as passage and converts to privacy by inserting a pushbutton on the interior side. If a factory privacy function is preferred, the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for 1-3/8 to 2 inch doors, and the Baldwin Estate 5103 privacy lever with 5048 rose is a privacy-function lever for decorative openings.
19) Does the Falcon B101 or the Accentra 4601LN replace the FC21 on a bedroom door?
Both are Grade 2 passage/hall/closet cylindrical lever locks, so they suit a hall or closet door, but neither is described with a privacy function. The Schlage FC21 converts to privacy with an interior pushbutton and can be released from outside with a small emergency unlock tool, which is what a bedroom or bath door usually calls for.
20) I want a matching decorative passage lever for a designer interior instead of the glass knob. What else is there?
The FC21 pairs an Alexandria glass knob with a Clybourn lever. For a decorative all-lever passage set, the Baldwin Estate 5103 passage lever with 5048 rose is a passage-function decorative lever, and Bravura offers Grade 2 passage leversets in several trims including the Atlanta and Orlando with round trim and the Tampa with square trim.
