Schlage Residential FC21-KYL-619-KIN – Frequently Asked Questions

1) Can the Schlage FC21 Kyle knob be used as both a passage and a privacy lock?
Yes. The FC21 Kyle ships as a passage set by default, and you convert it to privacy by inserting the privacy pushbutton on the interior side of the lock. From outside, a privacy-locked door opens with a small emergency unlock tool, so a bedroom or bath door can still be reached in an emergency. That means one part number covers both hall/closet and bed/bath openings in a unit.
2) Will the Schlage FC21 knob fit a 1-3/8 inch interior door, and what backset does it need?
Door thickness range is 1-3/8 inch to 1-3/4 inch, which covers both older interior doors and standard 1-3/4 inch slabs. Backset is not a decision you have to make: the latch supplied is a dual backset unit that adjusts to either 2-3/8 inch or 2-3/4 inch, the two bores you will find on existing doors. The knob is non-handed, so the same set works on a left or right hand door.
3) Will the FC21 latch work with the strike plate already in my door frame?
The latch has a 1/2 inch throw with a 1 inch by 2-1/4 inch faceplate on a 1/4 inch radius corner, and the strike supplied is a 1-5/8 inch by 2-1/4 inch full lip radius strike. If your frame already has a radius corner strike of that size, the new strike drops into the same cutout. Square corner frame preps will need the mortise corners squared or a square strike substituted.
4) Is the Schlage FC21 Kyle knob rated for a fire door?
The FC21 is available UL Listed for 90 minute fire door applications. It also carries ANSI/BHMA A156.2-2017 Grade 2 and ANSI/BHMA A156.39-2015 Residential Grade AAA certification. For a rated corridor or unit entry door in multi-family work, specify the UL Listed option rather than assuming the standard build covers it.
5) The FC21 Kyle is a residential lock. What do I use on a commercial corridor or classroom door instead?
The FC21 Kyle is specified for residential applications at Grade 2. For heavier commercial traffic on the same passage function, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with interchangeable core and a fire rating, covering 1-3/8 inch to 2-1/4 inch doors. The Corbin Russwin CK4310 is a Grade 1 passage/closet knob for 1-3/8 inch to 2 inch doors. The Falcon W101 is a Grade 2 medium duty passage knob with a fire rating and a 2-3/4 inch backset if you want to stay at Grade 2.
6) Which knobs look like a substitute for the FC21 Kyle but will not latch the door?
The FC21 Kyle is a working cylindrical lockset with a latch and strike. Dummy trim is not interchangeable with it: the Schlage A170 single dummy, the BEST 6K Series single dummy trim, the Cal-Royal BA40 dummy knob, the Bravura Biloxi dummy knobset and the Omnia 458/0 single dummy latchset all carry a dummy function and are surface trim with no latching mechanism. The Emtek Arts and Crafts hammered egg and Classic Crystal Georgetown and Providence sets are also dummy pairs. Use those only on inactive or closet leaves.
7) What is the closest Grade 2 knob alternative to the Schlage FC21 Kyle for a passage opening on a 1-3/8 inch to 1-3/4 inch door?
The Schlage FC21 Kyle is a Grade 2 non-keyed cylindrical knob with a passage/privacy function covering doors 1-3/8 inch to 1-3/4 inch. The Dexter C2000 Series passage ball knob matches on Grade 2, passage/hall/closet function and the same 1-3/8 inch to 1-3/4 inch door range, with a ball knob rather than a glass Kyle knob. The Corbin Russwin CK4410 is also Grade 2 non-keyed passage/closet for 1-3/8 inch to 1-3/4 inch doors, using a Global knob. Either is a straight functional swap where the decorative glass knob is not required.
8) I need a dedicated privacy knob instead of a passage lock that converts. What should I order?
The Schlage FC21 Kyle ships as passage by default and becomes privacy only when the pushbutton is inserted on the interior side. If you want a lock that is privacy out of the box, the Dexter C2000 Series privacy ball knob is Grade 2 non-keyed privacy/bed/bath for 1-3/8 inch to 1-3/4 inch doors. The Pamex FTF Baron privacy knob and the Cal-Royal BER20 are Grade 3 privacy knobs over the same door range. For a decorative option, the Baldwin Estate 5077 Bethpage is a privacy knob with the R027 rose.
9) My door is thicker than 1-3/4 inches. What passage knob covers it if the FC21 Kyle does not?
The FC21 Kyle covers doors 1-3/8 inch to 1-3/4 inch. For a thicker leaf, the Corbin Russwin CK4310 Grade 1 passage/closet knob covers 1-3/8 inch to 2 inches, and the Falcon X101 Grade 1 heavy duty passage knobset covers 1-3/8 inch to 2-1/4 inches. Among decorative knobs, the Deltana 6171 Round Knob entry and Deltana 3381 Egg Knob entry are listed for 1-3/8 inch to 2 inch doors.
10) What is included with the Schlage FC21 Kyle knob set, and what tools do I need?
Each set comes with the knobs, a 16-600 spring latch in dual option form (round faceplate or circular drive-in collar, both included) and a 10-027 full lip radius strike measuring 2-1/4 by 1-5/8 inches. Installation is a three step process needing only a screwdriver once the door is bored. Nothing else is required for a standard interior door.
11) I need the same door to be keyed instead of non-keyed. What takes the place of the FC21 Kyle?
The FC21 Kyle is a non-keyed knob. For a keyed opening on the same bore, the Dexter C2000 Series entry/office ball knob is Grade 2 keyed for 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal BER00 is a Grade 3 entrance/office knob with a Kwikset keyway over the same door range, and the Kwikset 400P-CP Polo keyed entry knob is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. For storeroom function, the Sargent 6G04 is a Grade 2 single cylinder knob lock.
12) What is a simpler passage knob if I do not need the glass Kyle design or the privacy conversion?
The FC21 Kyle carries a glass Kyle knob and converts from passage to privacy with a pushbutton. If the opening only needs plain passage, the Arrow MK01 and Arrow RK01 are Grade 2 non-keyed passage knobs for 1-3/8 inch to 1-3/4 inch doors, the RK01 with a ball knob. The Pamex FTF Baron passage knob is Grade 3 over the same door range, and the Kwikset 200P Polo passage knob ships with a 6AL latch and round corner strike.
13) What decorative passage knob can I use alongside the FC21 Kyle on a higher-end interior?
The FC21 Kyle is a glass knob on a choice of rose designs in satin nickel and matte black. If the millwork calls for solid brass, the Omnia 434/PA egg-shaped knob latchset is a passage/hall/closet set in solid brass with a 3 inch projection, and the Baldwin Estate 5011 Colonial passage knob with 5058 rose is also a passage/hall/closet set. The Baldwin Estate 5000 Baltimore passage set comes preconfigured with a 2-3/8 inch backset and full lip strike.
14) Can I match the FC21 Kyle glass knob across a whole building without changing the look?
Yes, within limits. The Kyle glass knob is offered in 619 Satin Nickel and 622 Matte Black, and the same knob is available on ten rose designs, so you can keep one knob style and vary the rose to match existing trim, or standardize on the Kinsler rose which is the standard option. Since the set is non-handed and covers 1-3/8 to 1-3/4 inch doors, one specification will drop onto most interior openings in a unit.
