Falcon D231P 626 – Frequently Asked Questions

1) What door prep does the Falcon D231 deadbolt need?
Standard tubular deadbolt prep: a 2-1/8 inch cross bore through the face, a 1 inch edge bore, and a door edge routed for a 1-1/8 x 2-1/4 inch square corner faceplate. On the frame side the standard strike is a 1-1/8 x 2-3/4 inch square corner plate with a metal dust box, anchored with three 3 inch screws. If your existing door already carries a 2-1/8 inch bore from another deadbolt, this drops into it.
2) Does the Falcon D231 work with a 2-3/8 or a 2-3/4 inch backset?
Both. The D231 bolt uses a lock-in-place helix design that adjusts between the 2-3/8 inch and 2-3/4 inch backsets, which are the two standard bores you will find on existing doors, so you do not have to know the backset before you order. Set it at install to match the cross bore you already have.
3) Can I key the Falcon D231 to my existing Best or Arrow SFIC cores?
Yes, if you order it less core. The B cylinder option ships the D231 with SFIC prep and no core, and Falcon's SFIC prep accepts Best and Arrow equivalent open keyways, so you can drop in the cores your facility already keys. If you'd rather stay conventional, the P6 option is a 6-pin cylinder in the Falcon G keyway, and the CP option is a 6-pin conventional cylinder in a Schlage keyway for buildings already standardized on Schlage. Two keys come with keyed cylinders.
4) Is the Falcon D231 rated for a commercial building, and what grade is it?
It is certified to ANSI/BHMA A156.5, 2001, Grade 2, and is a commercial, medium duty deadbolt. Grade 2 is the middle tier of the A156.5 auxiliary lock standard, which suits offices, retail, multi-tenant residential and back-of-house doors. For an opening that takes heavy abuse or where a spec calls out Grade 1, step up instead: the Design Hardware D1 Series is a Grade 1, extra heavy duty double cylinder deadbolt, and the Dexter DB1000 is a Grade 1 double cylinder unit.
5) I need a double cylinder deadbolt on a fire rated door. What are my options?
The D231 is offered with a UL 10C 3-hour fire rated option, used as an auxiliary lock on a fire rated opening. Two things to settle first: on a fire door the deadbolt must not be the only thing latching the door, and a double cylinder on an egress path is often restricted by code, so verify the opening with your AHJ before specifying. Among other deadbolts we carry with a fire rating on record, the Hager 3214 is a Grade 2 double cylinder for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal CRB800 is a Grade 1 heavy duty unit with a UL 3-hour fire rated latch, though that one is single cylinder.
6) Code says no double cylinder on this egress door. What single cylinder deadbolt replaces the Falcon D231?
A double cylinder deadbolt like the Falcon D231 is keyed on both faces, which many jurisdictions disallow on a required egress door. For the same opening with a thumbturn inside, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw for 1-3/8 inch to 1-3/4 inch doors, the Dexter DB2000 Series single cylinder is Grade 2 for the same door range, and the Arrow DBX61 is a Grade 2 cylinder by thumbturn deadbolt. Where the door must release with no key and no keyed outside face at all, the Arrow E60 is a non-keyed Grade 2 exit deadlock, blank plate outside and thumbturn inside, for 1-3/8 inch to 1-3/4 inch doors.
7) What is the closest equivalent to a Falcon D231 double cylinder deadbolt from another manufacturer?
The Falcon D231 is a Grade 2 double cylinder deadbolt for commercial openings, keyed on both sides with no thumbturn. The nearest peers by grade and function are the Hager 3214 Grade 2 double cylinder deadbolt with Schlage C keyway, the Dexter DB2000 Series Grade 2 double cylinder deadbolt, and the Delaney LU Series Grade 2 double cylinder deadbolt in stainless steel US32D. The difference that usually decides it is keying: the D231 uses the Falcon G keyway, while the Hager 3214 is supplied in the Schlage C keyway. If the building is already keyed to a Schlage C system the Hager cross-keys without a cylinder swap; if the site is on Falcon G, the D231 stays in the existing key system.
8) The door is 2 inches thick. Which double cylinder deadbolts will fit?
Door thickness is where most double cylinder deadbolts drop out. The Falcon D231 accepts doors from 1-3/8 inch through 2-1/4 inch with conventional cylinders, so a 2 inch door is inside its range. Among the double cylinder peers, the Dexter DB2000 Series is listed for 1-3/8 inch to 1-3/4 inch, the Dexter DB1000 Series Grade 1 for 1-3/8 inch to 1-7/8 inch, and the Design Hardware D1 Series Grade 1 for 1-3/4 inch. On a 2 inch leaf the D231 is the one that covers it without a spacer kit or a special-order tailpiece.
9) We need something heavier than Grade 2 on an exterior double cylinder opening. What steps up from the Falcon D231?
The Falcon D231 is certified to ANSI/BHMA A156.5 Grade 2 and rated medium duty. For a heavier double cylinder deadbolt, the Design Hardware D1 Series is Grade 1 and rated extra heavy duty for 1-3/4 inch doors, and the Dexter DB1000 Series is a Grade 1 double cylinder for 1-3/8 inch to 1-7/8 inch doors. Both narrow the door thickness range compared with the D231, so confirm the leaf before substituting on a thick or clad door.
10) Our facility is standardized on small format interchangeable core. Does the Falcon D231 work, or is there a better fit?
The Falcon D231 is available in a less-SFIC configuration, ordered without a core so the facility's own SFIC core drops in, alongside 6-pin conventional cylinder options in the Falcon G keyway and a Schlage cylinder option. If the standard is an Arrow or BEST style core, the Arrow E61 in 26D is a Grade 2 single cylinder deadlock supplied with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core with a 2-3/4 inch backset. Note both of those are single cylinder; the D231 is the double cylinder option in a less-core configuration.
11) Is a Callan 210S the same thing as a Falcon D231?
They are both double cylinder deadbolts, so they look interchangeable on a takeoff, but they are not certified to the same level. The Callan Model 210S is a Grade 3 double cylinder deadbolt, while the Falcon D231 is ANSI/BHMA A156.5 Grade 2 and rated medium duty for commercial use. On a specification that calls for Grade 2, the Callan 210S does not meet it. The Delaney LU Series double cylinder and the Dexter DB2000 Series double cylinder are the Grade 2 double cylinder peers that do.
12) Can I get several Falcon D231 deadbolts keyed alike on one key?
Yes. Keying is a required selection on the D231, and keyed alike (KA) is one of the choices alongside keyed different (KD), which is standard. Order all the locks for a building or a tenant suite on the same KA order and they run on one key. There is also a free-text field for special cylinder and keying requirements, which is where a master keying schedule or a specific bitting request goes. If you are ordering less cylinder, select None on the keying option.
13) What makes the Falcon D231 harder to defeat than a basic deadbolt?
Three things do the work. The bolt is solid zinc with a hardened steel anti-saw pin insert, so a blade in the gap between door and frame binds instead of cutting. A removable anti-pry shield and a tapered free-spinning trim ring resist wrenching the cylinder off the face. And the metal dust box anchors into the frame with three 3 inch screws, which reaches past the jamb into the stud, where most kick-ins actually fail.
14) I have a stack of Falcon D231 deadbolts and doors thicker than 2-1/4 inches. What should I use?
The D231 stops at 2-1/4 inches with a conventional cylinder, so anything thicker is out of range and the cylinder tailpiece will not reach. For thick doors, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock is rated 1-3/4 to 2-1/4 inches, which covers the same top end, but past 2-1/4 inches you are into a mortise deadlock rather than a bored one. Do not shim or extend the D231 to close the gap.
15) Does the Falcon D231 deadbolt have a handing, and does the double cylinder version change that?
No handing to specify. It is a bored tubular deadbolt with a keyed cylinder on each face, symmetric left to right, so the same part works on a left hand or right hand door. What you do have to specify on the order is keying, the bolt and faceplate configuration, and the strike, all three of which are required selections.
16) We want keypad or card access instead of a keyed deadbolt. What replaces the Falcon D231?
The Falcon D231 is a mechanical, non-electronic deadbolt keyed on both sides. For credential-based access on a similar opening, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, the Codelocks CL2210 is an electronic mortise deadbolt, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. These change the door prep and the credential program, so plan the keying handover before swapping a keyed cylinder opening to electronic.
17) What looks like a substitute for a Falcon D231 but is not a deadbolt lock?
Several deadbolt-named items in the same aisle are components, not complete locks. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, the BEST 8T is a T Series tubular deadbolt tube component, and the Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip. None of them supply a keyed deadbolt on their own. The Falcon D231 is a complete bored deadbolt with cylinders on both faces, ships with two keys, and includes a square corner strike with metal dust box, 1-1/8 inch by 2-3/4 inch.
18) Is a cylindrical deadlock like the Corbin Russwin DL3011 an alternative to the Falcon D231?
Only if the outside face should not be keyed the same way. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock in a cylinder by blank configuration for 1-3/4 inch to 2-1/4 inch doors, meaning one side is a blank plate rather than a second cylinder. The Falcon D231 is keyed on both faces, so it secures a glazed or sidelited opening where reaching through must not release the bolt. Where a blind inside face is acceptable and Grade 1 is required, the DL3011 covers the same 2-1/4 inch upper door thickness the D231 does.
19) Can a Deltana 7312KA2 double cylinder deadbolt be used in place of a Falcon D231 on a commercial job?
The Deltana 7312KA2 is a Grade 3 double cylinder deadbolt for 1-3/8 inch to 2 inch doors, supplied keyed alike in pairs. The Falcon D231 is ANSI/BHMA A156.5 Grade 2, listed for commercial applications, and accepts doors up to 2-1/4 inch. If the drawing calls for Grade 2, the Deltana does not satisfy it; the D231 also carries the thicker door up to 2-1/4 inch. Both can be ordered keyed alike where multiple openings share a key.
20) What finishes does the Falcon D231 deadbolt come in?
Five: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. All five are available with any of the three cylinder options, so you can match existing trim on a floor without giving up the keying you need. One catch worth knowing: the circular drive-in bolt option is 626 satin chrome only, so if you want a drive-in bolt in brass, that combination does not exist.
