Falcon X101S EG 626 – Frequently Asked Questions

1) Will the Falcon X101 passage knobset fit a 2 inch thick door?
Yes. The X101 covers 1-3/8 inch through 2-1/4 inch doors, which is a wider span than most cylindrical knobsets and takes in the thick fire-rated and lead-lined doors that stop a standard lock. Standard commercial 1-3/4 inch doors sit comfortably in the middle of that range, and older 1-3/8 inch interior doors are covered at the bottom. Backset is 2-3/4 inches, the commercial standard.
2) Does a passage knobset lock? What does the X101 actually do?
It does not lock, and that is the point. The X101 is a passage/hall/closet function (ANSI F75), non-keyed, with no cylinder and no button. Both knobs always retract the latch, so the door stays latched shut against a draft but never secures anything. Use it on corridor doors, closets, and any opening where you want the door held closed and freely operable from both sides. If you need to lock the room, this is the wrong function.
3) Can I use the Falcon X101 on a fire-rated door?
Yes. The X101 is UL Listed with a 3-hour A label rating, so it is code-legal on fire door assemblies up to that rating. That is what separates it from the residential-grade knobsets in the same shape, and it is the reason it shows up in school, hospital, and government specs where the corridor and stair doors are all rated openings.
4) Will the Falcon X101 drop into my existing ANSI frame prep?
If the frame is cut for a standard ANSI strike, yes. The standard strike shipped with the X101 is 1-1/4 x 4-7/8 inches, ANSI, square curved lip corner, no box, which is the prep most hollow metal commercial frames already carry. For a wood frame with a small full-lip mortise instead, order the 01-049 square corner or 01-048 round corner full lip strike at 1-5/8 x 2-1/4 inches rather than cutting the jamb to ANSI.
5) Is a Grade 1 knobset worth it over a Grade 2 passage lock for a school corridor?
For high traffic, yes. The X101 is ANSI/BHMA A156.2 Series 4000 Grade 1, the top commercial durability tier, tested to far higher cycle counts than Grade 2. Grade 2 alternatives in the same passage function include the Corbin Russwin CK4410 (1-3/8 to 1-3/4 inch doors) and the Dexter C2000 passage ball knob (1-3/8 to 1-3/4 inch). Those are appropriate for offices and light-use interior doors. For a corridor or classroom door cycled hundreds of times a day, Grade 1 is the specification that holds up.
6) What is the closest Grade 1 alternative to the Falcon X101 passage knobset from another manufacturer?
The Schlage D10S is the nearest straight equivalent: a Grade 1 heavy duty cylindrical non-keyed knob lock in the passage/hall/closet function with an Orbit knob, matching the X101's Grade 1 heavy duty passage/hall/closet configuration. The Corbin Russwin CK4310 is a second Grade 1 passage/closet cylindrical lock, with a Global knob and a 1-3/8 inch to 2 inch door thickness range against the X101's 1-3/8 inch to 2-1/4 inch range.
7) The opening needs to lock. What replaces a Falcon X101 when passage function is not enough?
The X101 is non-keyed passage/hall/closet, so it never locks. For a keyed opening at the same Grade 1 heavy duty level, the Sargent 8XG04 is a storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, matching the X101's 2-3/4 inch backset, and the BEST 8K Series is a Grade 1 heavy duty entrance function single cylinder knob lock. The Corbin Russwin CK4851 is a Grade 1 entrance/office knob lock with a conventional cylinder for 1-3/8 inch to 2 inch doors. For a bed or bath door needing only a thumbturn, the Dexter C2000 privacy ball knob is Grade 2 privacy/bed/bath.
8) Is there a lighter-duty passage knobset for interior doors that do not need Grade 1?
Several Grade 2 passage knobs cover the same hall and closet function on lower-traffic interior openings: the Corbin Russwin CK4410 Global knob, the Arrow MK01, the Arrow RK01 ball knob, and the Dexter C2000 passage ball knob, all Grade 2 non-keyed passage/hall/closet, all rated for 1-3/8 inch to 1-3/4 inch doors. The Pamex FTF Baron is a Grade 3 passage knob over the same 1-3/8 inch to 1-3/4 inch range. The Falcon X101 is Grade 1 heavy duty and carries a UL 3 hour A label fire rating, so fire-rated openings and high-traffic corridors stay with the X101.
9) Can a dummy knob be used in place of a Falcon X101 passage knobset?
No. A dummy knob has no latch and no working mechanism; it is surface trim for an inactive leaf or a closet door held shut by a catch. The Schlage A170 single dummy trim, the BEST 6K single dummy trim, the Cal-Royal BA40 dummy knob, the Bravura Biloxi dummy knobset, and the Omnia 434/0 single dummy are all dummy function. The Falcon X101 is a working latchset in the passage/hall/closet function with a 2-3/4 inch backset and an ANSI 1-1/4 inch x 4-7/8 inch strike, so it latches the door. If the door has to stay closed on its own, a dummy will not substitute.
10) Do I need to worry about handing when ordering the Falcon X101 knobset?
No. The X101 is non-handed, so one part number works on a left or right hand door swinging either way. For a property manager stocking spares across a building, that means a single shelf item covers every passage opening regardless of swing, and nobody has to stand in the hallway working out the hand before placing the order.
11) A passage lock has no key, so why does the Falcon X101 take an interchangeable core?
The X101 chassis is built on the same interchangeable core platform as the keyed X Series functions, and the cores accept SFIC product from other manufacturers. Practically, that means a facility running one SFIC keyway can put passage and keyed openings on the same chassis family and the same core inventory, and a passage door can later be converted without changing the hardware standard. If your building is already on small format interchangeable core, this keeps the passage doors inside that system.
12) I need a knob on a door that is never meant to latch at all. Is the X101 right?
No. The X101 has a working latch, so it pulls the door shut and holds it. For a door leaf that just needs a knob for appearance and pull, such as the inactive half of a pair or a closet with a ball catch, you want a dummy trim instead: the BEST 6K single dummy trim, the Schlage A170 single dummy, or the Cal-Royal BA40 dummy knob. Those mount a knob with no latch and no chassis.
13) Will the Falcon X101 hold up in a coastal or high-humidity building?
The standard build is brass or cold-formed steel with a zinc dichromate coating for rust resistance. For genuinely corrosive environments there is an optional XC construction with stainless steel and a nonferrous chassis, which is what to specify for marine and shoreline work. On finish, 630 satin stainless steel is the one to pair with it.
14) What is the difference between the Falcon X101 and the Schlage A170 for a closet door?
The Schlage A170 is a Grade 2 heavy duty cylindrical non-keyed knob in the dummy function for 1-3/8 inch to 1-7/8 inch doors, meaning it mounts as trim only. The Falcon X101 is Grade 1 heavy duty in the passage/hall/closet function with a latch and a 1-3/8 inch to 2-1/4 inch door thickness range. On a closet door with a roller catch, the A170 is the right form; on a closet door that needs a latch and strike, the X101 is.
15) Which passage knob suits a residential or light commercial interior door rather than a commercial corridor?
The Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike for interior hall and closet doors, and the Kwikset 200P-CP pairs a round corner adjustable latch with a round corner strike. The Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Bravura Albany and Lynchburg Grade 2 passage knobsets cover decorative interior openings. The Falcon X101 is specified commercial, Grade 1 heavy duty, with a 2-3/4 inch backset and interchangeable core compatible with SFIC products from other manufacturers, which is what a corridor or institutional opening under a keying program needs.
16) Which Grade 1 knob locks share a keying platform and backset with the Falcon X101 for standardizing a facility?
The Falcon X101 uses a 2-3/4 inch backset and interchangeable cores compatible with SFIC products from other manufacturers, so keyed openings elsewhere in the building can run the same core format. The BEST 8K Series is a Grade 1 heavy duty entrance function knob lock and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset, letting a facility keep one knob platform across passage, entrance, and storeroom doors. The Corbin Russwin CK4310 covers passage/closet at Grade 1 with a Global knob if the Global trim is already standard on site.
17) Does the Sargent 6G04 substitute for a Falcon X101 on a closet door?
Not directly. The Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, so it is keyed and the outside knob stays locked. The Falcon X101 is non-keyed Grade 1 heavy duty passage/hall/closet, free-turning from both sides. For a keyed closet at the same heavy duty Grade 1 level, the Sargent 8XG04 storeroom/closet knob lock is the closer match.
18) Is exit device knob trim an alternative to the Falcon X101?
No. The Sargent 28C-KNOB is exit device trim with knob and rose in the entrance function for 1-3/4 inch doors, and the Sargent 78-2875 is an outside knob only with B design; both mount to an exit device rather than working as a standalone lock. The Imperial USA ED-BKL580 is likewise knob trim in the storeroom function. The Falcon X101 is a complete cylindrical latchset with its own chassis, 2-3/4 inch backset and ANSI strike, installed in a bored door prep.
19) What knob styles and finishes does the Falcon X101 come in, and can I match my existing building standard?
Six finishes across six knob designs, and every combination is orderable. Finishes are 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, and 630 satin stainless steel. Knob designs are Elite-Gala (EG), Elite-York (EY), Hana-Gala (HG), Hana-York (HY), Troy-Gala (TG), and Troy-York (TY). If your building standard is 626 satin chrome, which most commercial specs are, pick the knob design that matches the keyed openings already installed.
20) Can the knobs be pulled off the Falcon X101 by someone tampering with it?
The knobs are held by a spring-loaded retainer that cannot be depressed while the lock is engaged, so there is no exposed set screw to back out from the corridor side. The roses are heavy wrought brass, bronze or stainless steel over steel through-bolted rose inserts, so the trim is clamped through the door rather than held by screws into the door face. That through-bolting is what keeps the assembly tight on an abused door.
21) Is there a keyless combination knob lock instead of a Falcon X101 passage knobset?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, covering 1 3/16 inch to 2 inch doors, for an opening that needs code-controlled access without a key. It differs in behavior from the Falcon X101, which is non-keyed passage/hall/closet and turns freely from both sides with no code and no locking. The X101 also covers doors up to 2-1/4 inch thick.
22) Which knobset matches a decorative interior opening where the Falcon X101 trim is too plain?
The Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection in the passage/hall/closet function. The Baldwin Estate 5000 Baltimore knob with 5048 rose is a preconfigured passage lock with a 2-3/8 inch backset and full lip strike, and the Bravura Dallas passage knobset with rectangle trim is Grade 2 in US4 satin brass. The Falcon X101 is a commercial Grade 1 knobset on a 2-3/4 inch backset, offered in bright brass, satin brass, satin bronze oil-rubbed, bright chrome, satin chrome and satin stainless steel.
