Falcon D261 626 – Frequently Asked Questions

1) Will the Falcon D261 deadbolt fit a 1-3/4 inch commercial door?
Yes, and it covers a wider range than most. The D261 handles door thickness from 1-3/8 to 2-1/4 inches, so 1-3/4 inch commercial doors sit in the middle of the range and thicker doors up to 2-1/4 inches are still covered. Backset adjusts in the field between 2-3/8 and 2-3/4 inches using a lock-in-place helix, so you don't have to know the existing bore centerline before you order.
2) What door prep does the Falcon D261 need drilled?
Prep is a 1 inch housing bore with a 1-1/8 x 2-1/4 inch square-corner faceplate mortise on the door edge, at either a 2-3/8 or 2-3/4 inch backset. On the frame side, the standard strike is a 1-1/8 x 2-3/4 inch square corner with a metal dust box, fastened with three 3 inch screws that reach into the framing rather than stopping at the jamb. Falcon supplies templates for the hole locations.
3) Is the Falcon D261 deadbolt ANSI Grade 1 or Grade 2?
Grade 2 under ANSI/BHMA A156.5, medium duty, and rated commercial rather than residential. For an MRO spec that calls for Grade 1 on a deadbolt, this one does not meet it, and options like the Corbin Russwin DL3011 Grade 1 cylindrical deadlock or the Design Hardware D1 Series Grade 1 deadbolt are where to look instead.
4) I have a stack of doors needing the same deadbolt but some are thicker than 1-3/4 inches. Will one Falcon D261 part number cover them all?
Yes, that is the practical reason to standardize on the D261 across a building. One part number covers 1-3/8 through 2-1/4 inch doors and adjusts to either a 2-3/8 or 2-3/4 inch backset in the field, so a mixed-age door stock takes the same lock and the same box on the truck. Most competing Grade 2 deadbolts stop at 1-3/4 inches, including the Dexter DB2000 single cylinder and the Hager 3215, both listed at 1-3/8 to 1-3/4 inches. Order all doors in one finish and the openings match.
5) Can I key the Falcon D261 into my building's master key system?
No, and this is the thing to catch before ordering. The D261 takes no cylinder and no keyway, so there is nothing to key or master. It secures from the inside only. For an opening that has to fall under a master key system, specify a keyed deadbolt instead, such as the Hager 3115 Grade 2 cylinder-by-thumbturn with a Schlage C keyway.
6) The door needs to be locked from outside with a key, not just a thumbturn - what should be used instead of a Falcon D261?
The Falcon D261 is non-keyed and one-sided, so it throws and retracts only from the interior thumbturn and has no outside cylinder. When the opening needs outside key control, a cylinder x thumbturn deadbolt is the correct part instead. The Arrow DBX61 is a Grade 2 single cylinder deadbolt in cylinder x thumbturn function, and the Dexter DB2000 single cylinder is a Grade 2 cylinder x thumbturn unit for doors 1-3/8 inch to 1-3/4 inch. The Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard.
7) Is there a fire rated deadbolt alternative to the Falcon D261 for a rated opening?
The Falcon D261 is available with UL 10C 3-hour fire rated options as an auxiliary lock. Comparable fire rated deadbolts include the Hager 3215 single cylinder Grade 2 with a 1 inch throw and the Hager 3115 Grade 2 cylinder x thumbturn with a Schlage C keyway, both carrying a fire rating and covering doors 1-3/8 inch to 1-3/4 inch. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Hager and Cal-Royal units are keyed on the outside, where the D261 is thumbturn only.
8) What is the closest equivalent to a Falcon D261 from another brand for a non-keyed thumbturn-only opening?
The Falcon D261 is a Grade 2 non-keyed one-sided deadbolt operated by a thumbturn with no outside trim. The nearest peer with the same operation is the Arrow E60 exit deadlock, a Grade 2 non-keyed unit with a blank plate on the outside and a thumbturn on the inside, rated for doors 1-3/8 inch to 1-3/4 inch thick. The Callan 205S is also one-sided, in a Grade 3 half-bore version. The Falcon D261 accepts doors from 1-3/8 inch through 2-1/4 inch, so on a thicker door the Falcon covers a range the Arrow E60 does not.
9) What is a Grade 1 alternative when a Grade 2 deadbolt like the Falcon D261 is not enough for the spec?
The Falcon D261 is certified to ANSI/BHMA A156.5 Grade 2 at a medium duty level. Where the drawing calls for Grade 1, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch, and the Dexter DB1000 single cylinder is Grade 1 for doors 1-3/8 inch to 1-7/8 inch. The Design Hardware D1 is a Grade 1 double cylinder deadbolt at an extra heavy duty level for 1-3/4 inch doors. All three are keyed cylinder units rather than the D261's non-keyed thumbturn-only operation, so the switch changes the function as well as the grade.
10) Which deadbolts fit a door thicker than 1-3/4 inch if the Falcon D261 is not being used?
The Falcon D261 covers door thickness from 1-3/8 inch to 2-1/4 inch, which is a wider band than most tubular deadbolts hold. Among comparable units, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock is listed for 1-3/4 inch to 2-1/4 inch doors, and the Deltana 7312KA2 double cylinder covers 1-3/8 inch to 2 inch. The Dexter DB1000 reaches 1-7/8 inch. Confirm the measured door thickness before selecting, since the Corbin Russwin DL3011 starts at 1-3/4 inch and will not suit a thinner leaf.
11) What deadbolt takes an interchangeable core when the Falcon D261 has no cylinder?
The Falcon D261 is a non-keyed thumbturn deadbolt with no cylinder or keyway, so it cannot be brought into a small format interchangeable core system. For an SFIC opening, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC less core, for doors 1-3/8 inch to 1-3/4 inch, and the Deltana CL200LAIC is a Grade 2 single deadbolt with a 2-3/4 inch backset supplied for an interchangeable core. The Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
12) How does a one-sided thumbturn deadbolt hold up against someone attacking the door?
The D261 is built around the common attacks on a deadbolt. 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. The trim ring is tapered and free-spinning, which defeats a wrench or pliers grabbing the outside. A removable anti-pry shield covers the bolt against an ice pick worked through the door gap. And the metal dust box reinforcer with three 3 inch screws anchors into the frame studs, which is what actually stops a kick-in.
13) Is the Falcon D261 deadbolt Buy American Act compliant for a government job?
Yes, the D261 is a BAA compliant product, which is what lets it onto government and institutional work that requires domestic sourcing. Paired with the ANSI/BHMA A156.5 Grade 2 rating, it covers the two things a public-sector spec usually asks for on an auxiliary deadbolt.
14) I need a thumbturn deadbolt with no outside trim on an exit door. Is the Falcon D261 the right one, or should I use an exit deadlock?
Both do the same job from different directions. The Falcon D261 is a bored, one-sided thumbturn deadbolt: nothing on the outside face at all, so the door reads blank from the pull side. The Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside, fitting doors 1-3/8 to 1-3/4 inches, which gives you a finished plate on the outside face instead of bare door. Choose the D261 when you want the smaller 1 inch bore and coverage up to 2-1/4 inch doors; choose a blank-plate deadlock when the outside prep already exists and needs covering.
15) Does the Falcon D261 thumbturn meet ADA requirements?
Yes. The thumbturn on the D261 meets ADA compliance requirements for accessible operation, so it works on openings where the hardware has to be operable without tight grasping or twisting of the wrist. It is a mechanical, non-electronic lock, so there is nothing to power or maintain on the accessibility side.
16) What is the closest one-sided deadbolt to the Falcon D261 if I need something different?
For the same one-sided function, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, so it is lighter duty than the D261's Grade 2 medium-duty rating but the same idea: thumbturn inside, nothing outside. If the opening actually needs key control from one side, the closest step across is a cylinder-by-thumbturn Grade 2 unit such as the Cal-Royal CB160 with its tamper-resistant cylinder guard or the Deltana CL200LA at a 2-3/4 inch backset. Nothing in that group is a drop-in for the D261 prep, so the door will need re-prepping if you switch.
17) Is there a lighter-duty deadbolt than the Falcon D261 for a low-traffic interior door?
The Falcon D261 is a commercial Grade 2 medium duty deadbolt. For openings that do not carry commercial traffic, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for doors 1-3/8 inch to 1-3/4 inch, and the Callan 200S is a Grade 3 single cylinder with square trim. Both are keyed cylinder x thumbturn units, so they add an outside cylinder the D261 does not have.
18) What deadbolt should be used when the opening needs a key on both sides instead of a Falcon D261 thumbturn?
The Falcon D261 uses an interior thumbturn with no outside trim, so it cannot be keyed on either face. Double cylinder deadbolts key both sides: the Delaney LU Series 320601 is a Grade 2 double cylinder in stainless steel US32D, the Dexter DB2000 double cylinder is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, and the Callan 210S is a Grade 3 double cylinder. Double cylinder units are restricted on egress doors in many jurisdictions, so verify the code requirement for the opening before ordering.
19) Which parts look like a substitute for a Falcon D261 but will not work as one?
The Falcon D261 is a complete bored deadbolt assembly with bolt, thumbturn, trim ring, strike and dust box. Several deadbolt-named items are not complete locks: the Baldwin Reserve 8BR0618001 is a deadbolt spacer, 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. The International Door Closers DH-1821 is a hook bolt deadlock, a mortise-style lock body rather than a bored thumbturn deadbolt, and it will not fit the D261 door prep.
20) What is an electronic alternative to a mechanical thumbturn deadbolt like the Falcon D261?
The Falcon D261 is a mechanical, non-electronic deadbolt. Where credential or code access is wanted on the same opening, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, 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. Surface-mounted electronic units such as the Codelocks CL2200 mount to the door face rather than into the D261's bored prep.
21) Which deadbolt has an ADA-friendly thumbturn if the Falcon D261 is not the chosen unit?
The Falcon D261 uses a thumbturn design that meets ADA compliance requirements for accessible operation. The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch, and the Arrow E60 pairs a thumbturn with a blank outside plate at Grade 2. The Cal-Royal LSD adds an outside cylinder, so on an egress-only opening where no outside operation is wanted the Arrow E60 is the closer match in function.
