Falcon D261M 626 – Frequently Asked Questions

1) Does the Falcon D261M deadbolt have a key cylinder on the outside of the door?
There is no cylinder on it at all. The D261M is a one-sided, non-keyed deadbolt: thumbturn on the inside, blank rose (a plain plate, no keyhole) on the outside, and no keyway to specify. The bolt throws and retracts from the interior only. That fits doors you secure from inside and never need to open from the other side, such as stockrooms, mechanical and electrical rooms, back-of-house and exit-only openings. If anyone has to get in with a key, this is the wrong part; the Arrow DBX61 is a Grade 2 cylinder x thumbturn deadbolt that does that job.
2) Can the Falcon D261M go on a door already bored for a 2-3/4 inch backset?
Yes. Backset on the D261M adjusts in the field between 2-3/8 and 2-3/4 inches, the two standard bored backsets, and a lock-in-place helix holds whichever setting you choose instead of letting it drift back. You are not ordering a backset, you are setting it at the door. For fresh prep, the deadbolt housing is 1 inch in diameter and the door edge takes a 1-1/8 x 2-1/4 inch faceplate mortise.
3) Can the Falcon D261M deadbolt be keyed into our master key system?
No. It is a non-keyed lock with no cylinder and no keyway, so there is nothing to pin and it cannot join a master key or small format interchangeable core schedule. When the opening has to sit on the keying schedule, go keyed instead: the Arrow E61 Grade 2 deadlock comes with SFIC prep less core, and the Arrow DBX61 or Dexter DB2000 single cylinder are Grade 2 cylinder x thumbturn.
4) What is the closest alternative to the Falcon D261M if I need a non-keyed deadbolt with a blank plate outside from another brand?
The Arrow E60 exit deadlock is the direct cross-brand match: Grade 2, non-keyed, blank plate by thumbturn, same function set as the Falcon. Door thickness is the difference to check. The Arrow is listed for 1-3/8 to 1-3/4 inch doors, while the D261M runs 1-3/8 to 2-1/4, so anything thicker than 1-3/4 goes to the Falcon. The Callan 205S is another one-sided deadbolt, but it is Grade 3, a lighter tier than either of these.
5) Which deadbolt goes on a fire-rated door assembly?
The Falcon D261M is offered with UL 10C 3-hour fire rated options for use as an auxiliary lock on fire-rated door assemblies. Among comparable deadbolts, the Hager 3115 and 3215 cylinder x thumbturn deadbolts and the Hager 3214 double cylinder deadbolt all carry a fire rating, each listed for 1-3/8" to 1-3/4" doors, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. Confirm the assembly's label allows an auxiliary deadbolt before specifying any of them.
6) Is there a non-keyed thumbturn deadbolt from another manufacturer that matches the Falcon D261M function?
The Arrow E60 is the closest match in function. It is a Grade 2 exit deadlock listed as non-keyed, with a blank plate x thumbturn arrangement - the same idea as the Falcon D261M, which is a Grade 2 non-keyed deadbolt with a thumbturn inside and a blank rose outside. The two split on door thickness: the E60 is listed for 1-3/8" to 1-3/4" doors, while the D261M is built for 1-3/8" to 2-1/4". On a 2" door the Falcon is the one that fits; on a standard 1-3/4" door either function is available.
7) What deadbolt should I use instead of the Falcon D261M if the outside of the door has to be unlocked with a key?
The Falcon D261M is non-keyed - blank rose outside, thumbturn inside - so it never opens from the exterior. For an opening that needs exterior key control at the same grade, the Arrow DBX61 is a Grade 2 deadbolt with a cylinder x thumbturn function, the Dexter DB2000-SCT is a Grade 2 single cylinder deadbolt with cylinder x thumbturn listed for 1-3/8" to 1-3/4" doors, and the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard. All three add a cylinder bore to the door prep that the D261M does not require.
8) Which commercial deadbolts fit a door thicker than 1-3/4 inches?
The Falcon D261M covers 1-3/8" to 2-1/4", which takes in the thick doors most tubular deadbolts stop short of. Among comparable products, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock is listed for 1-3/4" to 2-1/4" doors in a cylinder x blank configuration, and the Deltana 7312KA2 Grade 3 double cylinder deadbolt is listed for 1-3/8" to 2". Others end at 1-3/4": the Dexter DB2000-SCT, the Hager 3115, and the Arrow E60 are all listed for 1-3/8" to 1-3/4". Measure the leaf before ordering.
9) What is the Grade 1 alternative when the spec calls for Grade 1 instead of a Grade 2 deadbolt?
The Falcon D261M is certified to ANSI/BHMA A156.5 Grade 2 at a medium duty level. Grade 1 deadbolts in the same class include the Accentra D111 single cylinder with a 2-3/8" backset for 1-3/8" to 1-3/4" doors, the Design Hardware D1 double cylinder rated extra heavy duty for 1-3/4" doors, the Corbin Russwin DL3011 cylindrical deadlock for 1-3/4" to 2-1/4" doors, and the Delaney LM Series single cylinder less core in dull chrome US26D. Each of those is a keyed device, so a Grade 1 spec on this opening means giving up the blank exterior face.
10) I want a deadbolt with no key on the outside. Is a double cylinder deadbolt what I need?
That is the opposite of what you described. Double cylinder means a key cylinder on both faces, so it takes a key to unlock from the inside as well; the Callan 210S and the Dexter DB2000 double cylinder are built that way. What you want is the one-sided function the Falcon D261M has: thumbturn inside, blank rose outside, no keyhole on either face. Anyone inside works the bolt by hand, and nobody operates it from outside.
11) What strike comes with the Falcon D261M, and will it hold in a wood frame?
Standard strike is a square corner strike, 1-1/8 x 2-3/4 inches, backed by a metal dust box reinforcer. The box anchors with three 3 inch screws, long enough to pass through the jamb and bite into the framing behind it, which is what actually resists a kick; a strike fastened to the jamb alone tears out. The bolt is specified at 0.82 x 0.62 x 1 inches, so the frame pocket has to take that.
12) Is a Grade 2 deadbolt like the Falcon D261M enough for a commercial building?
The D261M is certified to ANSI/BHMA A156.5, 2001, Grade 2 and rated medium duty for commercial use. Grade 2 is the middle of the three A156.5 tiers, and it is the usual pick for offices, retail, multi-tenant residential and back-of-house openings with normal traffic. Where a door takes heavy abuse or real forced-entry exposure, step up to Grade 1: the Dexter DB1000 single cylinder covers 1-3/8 to 1-7/8 inch doors, and the Corbin Russwin DL3011 cylindrical deadlock is Grade 1 for 1-3/4 to 2-1/4 inch doors, though the DL3011 is cylinder by blank plate rather than a thumbturn.
13) Which deadbolts adjust between a 2-3/8 and a 2-3/4 inch backset?
The Falcon D261M uses a lock-in-place helix backset that sets to either 2-3/8" or 2-3/4", so one part number covers both common bore centers. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt listed with an adjustable backset for 1-3/8" to 1-3/4" doors, and the Brinks Raleigh E2401 and Mendocino E2402 single cylinder deadbolts are listed with a 4-way adjustable backset. Fixed-backset comparables have to be ordered to the measured dimension: the Accentra D111 is a 2-3/8" backset and the Deltana CL200LA is a 2-3/4" backset.
14) Is there another one-sided deadbolt with no cylinder on the outside face?
Two comparable products keep the exterior blank. The Callan 205S is a Grade 3 one-sided half-bore deadbolt, so the bore does not carry all the way through the leaf. The Arrow E60 is a Grade 2 exit deadlock in a blank plate x thumbturn configuration for 1-3/8" to 1-3/4" doors. The Falcon D261M is the Grade 2, medium duty version of the same one-sided idea, covering 1-3/8" to 2-1/4" doors with an adjustable 2-3/8" or 2-3/4" backset. Check which door prep you already have before choosing.
15) Can an Emtek 2050 or 2051 be used in place of a Falcon D261M?
Not in the same door. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch in a cylinder x thumbturn function, and a mortise deadbolt needs a pocket routed into the door edge. The Falcon D261M is a bored deadbolt: a 1" housing bore through the face with a 1-1/8" x 2-1/4" faceplate mortise on the edge. The International Door Closers DH-1821 is likewise a hook bolt deadlock with a flat faceplate, a different bolt form altogether. Swapping between these means new door prep, not just new hardware.
16) Will an Arrow 460 or a Baldwin 8BR0618001 work as a replacement deadbolt?
Neither one is a lock. The Arrow 460 is a mortise lock strike with latchbolt x deadbolt functions and a straight lip, so it is frame-side hardware; the Falcon D261M already comes with a square corner strike and metal dust box measuring 1-1/8" x 2-3/4". The Baldwin 8BR0618001 is a deadbolt spacer, and the BEST 8T is a tubular deadbolt tube component from the T Series. Those are accessories and subassemblies. If you need a complete bolt with trim, the D261M or another full deadbolt is the item to order.
17) What deadbolt should I specify when both sides of the door need a key?
The Falcon D261M operates from a thumbturn on the inside only, so a double cylinder function calls for a different part. The Dexter DB2000-DCT is a Grade 2 double cylinder deadbolt for 1-3/8" to 1-3/4" doors, the Delaney LU Series double cylinder is Grade 2 in stainless steel US32D, and the Callan 210S is a Grade 3 double cylinder. Double cylinder means a key is required from the inside as well, so confirm the egress requirements for the occupancy before specifying it.
18) Which deadbolt fits a facility standardized on interchangeable core keying?
The Falcon D261M is non-keyed, so it stays outside the key system entirely - useful on doors you want off the master chart. Where the opening does have to join the system, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8" to 1-3/4" doors, the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt with a 2-3/4" backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt. Cores are ordered separately on all three.
19) How well does the Falcon D261M resist someone sawing or prying at the bolt?
A hardened steel anti-saw pin sits inside the solid zinc bolt, so a blade worked into the gap between door and frame hits the pin instead of cutting straight through. On the outside face, the tapered trim ring spins free, which leaves a wrench or a pair of pliers nothing to grab and twist off, and a security shield behind the trim blocks ice-pick attacks on the mechanism.
20) Does the Falcon D261M thumbturn meet ADA requirements?
The thumbturn on the D261M is ADA compliant for accessible operation, so the deadbolt itself is not what fails an accessibility review. That covers the lock only. Whether the full opening is compliant also depends on the primary latching hardware, door operating force and clearances, none of which this deadbolt controls.
21) Will the Falcon D261M match the satin chrome hardware already on our doors?
Order it in 626 satin chrome, the finish most commercial buildings standardize on and the same one commonly written as US26D, and it will line up with existing satin chrome levers, closers and trim. Four other finishes are offered: 605 bright brass, 606 satin brass, 613 oil-rubbed satin bronze, and 625 bright chrome. Five in total, and finish is the only choice that changes what shows on the door face.
22) What replaces a thumbturn deadbolt when the door needs code or credential access?
The Falcon D261M is a mechanical deadbolt with no electronic option, so credential access means a different device. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. Surface-mounted and mortise electronic bolts prep differently from a bored deadbolt, so verify the door prep against the model you pick.
