Falcon D241P 626 – Frequently Asked Questions

1) Will the Falcon D241 deadbolt fit a 2 inch thick door?
Yes, a 2 inch door sits comfortably inside the range. The D241 accommodates door thickness from 1-3/8 inches up to 2-1/4 inches, which is wider than most medium duty deadbolts run. For comparison, the Dexter DB2000 single cylinder, the Hager 3215 and the Accentra D111 are all listed for 1-3/8 to 1-3/4 inch doors. If your building has a mix of standard 1-3/4 inch commercial doors plus thicker or built-up doors, the D241 covers both without a second part number.
2) What backset does the Falcon D241 deadbolt use, and will it fit a door already bored for 2-3/4 inches?
Both of the standard backsets. The D241 uses a lock-in-place helix design that adjusts in the field between 2-3/8 inches and 2-3/4 inches, so the same lock drops into either existing prep and you set it on the door rather than picking a backset at the order form. Those are the two backsets nearly every bored deadbolt prep in North America uses. Door prep itself is a 2-1/8 inch cross bore with a 1 inch edge bore for the bolt housing, which is the same cross bore a standard cylindrical lockset uses.
3) How far does the Falcon D241 bolt throw, and will it land in the strike already cut into my frame?
One inch of throw on a solid zinc bolt with a hardened steel anti-saw pin insert. The strike that goes with it is a square corner strike with a metal dust box, 1-1/8 by 2-3/4 inches, so a frame already routed for that footprint takes it directly. The dust box is the part worth attention: it anchors into the wood frame with three 3 inch screws, and those screws are what resist a kick, not the bolt itself. If your existing frame is cut for a different strike footprint, the frame needs to be routed to match rather than the bolt adjusted.
4) Is a single cylinder deadbolt like the Falcon D241 right for a commercial door, or do I need a double cylinder?
Cylinder outside, thumbturn inside is what the D241 is: key from the exterior, and anyone inside turns the thumbturn to get out with no key. That is the usual specification for an occupied commercial space, because a key requirement on the egress side is what causes trouble in an inspection. Go double cylinder only when there is glazing close enough to the lock that someone could reach the turn, and only where the authority having jurisdiction allows it. In that case the equivalents are the Hager 3214 Grade 2 double cylinder, the Dexter DB2000 double cylinder for 1-3/8 to 1-3/4 inch doors, or the Delaney LU Series Grade 2 double cylinder.
5) Does the Falcon D241 deadbolt hold the door closed on its own, or do I still need a lockset?
A deadbolt only, so it does not hold the door closed. There is no latchbolt and no spring latch in the D241: throw the bolt and the door is locked, retract it and nothing keeps the door in the frame. It goes above a knob or lever lockset, or above a passage set on a door that only needs to stay shut, and it is the security bolt while the lockset handles day to day operation. Budget for both the deadbolt prep and the lockset prep on a door that currently has neither.
6) Is a Grade 2 deadbolt like the Falcon D241 enough for a commercial building, or should I spec Grade 1?
The D241 is certified to ANSI/BHMA A156.5, 2001, Grade 2 and is a medium duty commercial lock. That suits tenant doors, offices, storage rooms, back-of-house and multi-tenant residential, which is most of the openings in a typical portfolio. Where a drawing calls out Grade 1, or the opening is a heavily used main entry, step up: the Accentra D111 is Grade 1 cylinder by thumbturn for 1-3/8 to 1-3/4 inch doors, the Dexter DB1000 single cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors, and the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 to 2-1/4 inch doors, though that one is cylinder by blank plate with no thumbturn.
7) What is a direct equivalent to the Falcon D241 if a commercial spec calls for a Grade 2 single cylinder deadbolt?
The Falcon D241 is an ANSI/BHMA A156.5 Grade 2 deadbolt in a cylinder x thumbturn function. Peers carrying that same grade and function include the Arrow DBX61, the Hager 3215 single cylinder deadbolt with 1 inch throw, the Dexter DB2000-SCT, and the Cal-Royal CB160, which adds a tamper-resistant cylinder guard. The one dimension to confirm before swapping is door thickness: the D241 accommodates 1-3/8 to 2-1/4 inch doors, while the Hager 3215 and the Dexter DB2000-SCT both list 1-3/8 to 1-3/4 inch.
8) Which deadbolt should I use on a 2 inch thick door instead of the usual Grade 2 tubular deadbolt?
The Falcon D241 itself is prepped for 1-3/8 to 2-1/4 inch doors, so it covers a 2 inch leaf directly. If the opening calls for a different make, the Corbin Russwin DL3011 lists a 1-3/4 to 2-1/4 inch door thickness range, though it is a cylinder x blank deadlock with no inside turn, and the Deltana 7312KA2 lists 1-3/8 to 2 inch as a Grade 3 double cylinder. Most of the Grade 2 tubular deadbolts in the same class, including the Dexter DB2000-SCT and the Hager 3115, stop at 1-3/4 inch.
9) The opening gets heavy daily use. What Grade 1 deadbolt covers the same single cylinder function as the Falcon D241?
The Falcon D241 is rated Grade 2 for medium-duty commercial use. Grade 1 deadbolts in the same cylinder x thumbturn function include the Accentra D111 with a 2-3/8 inch backset, the Dexter DB1000-SCT for 1-3/8 to 1-7/8 inch doors, the Deltana CL200LM, and the Cal-Royal CRB800 heavy-duty single cylinder with a UL 3-hour fire rated latch. Note the backset: the D241 adjusts between 2-3/8 and 2-3/4 inch, while the Accentra D111 is a 2-3/8 inch backset lock.
10) Which deadbolts take a small format interchangeable core so I can key them into an existing SFIC system?
The Falcon D241 is offered in a B less-SFIC configuration, which ships prepped to receive a core you supply. Comparable locks set up the same way include the Arrow Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, the Deltana CL200LAIC Grade 2 interchangeable core deadbolt with a 2-3/4 inch backset, and the Delaney LM Series 301702, a Grade 1 single cylinder less-core deadbolt in a dull chrome US26D finish.
11) The building is keyed on Schlage C. Which deadbolts drop into that keyway?
The Falcon D241 can be ordered with the CP conventional cylinder, a 6-pin Schlage cylinder, in the C keyway alongside the standard Falcon G keyway. If the job is being split across brands on the same key system, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway, the Hager 3214 is the double cylinder version in the same keyway, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder.
12) If I order the Falcon D241 less core, what do I have to supply myself?
Order the B option and you supply the core. That build arrives prepped for a small format interchangeable core with no core fitted, which is what you want when the facility already runs its own SFIC keying and the locksmith cores everything on site. The D200 Series accepts BEST and Arrow equivalent open keyways in SFIC format, plus the Falcon G keyway. If you would rather it arrive ready to hang, P6 gives you the 6-pin conventional cylinder in the G keyway and CP gives you a 6-pin conventional Schlage cylinder, both keyed different with two cut keys in the box. Arrow's E61 in SFIC prep less core is the comparable less-core option from another brand.
13) Can the Falcon D241 deadbolt be used on a fire rated door?
The D241 carries an optional UL 10C 3 hour fire rating as an auxiliary lock. Auxiliary is the operative word: the deadbolt is rated for use alongside the fire door's own latching device, not as the thing that latches the door. So the door still needs a fire rated lockset or exit device doing the latching, and the D241 adds the security bolt on top. If the rated hardware has to come from one supplier, the Hager 3115 and 3215 Grade 2 cylinder by thumbturn deadbolts are also fire rated in our records.
14) What has to happen at install for a Falcon D241 to actually resist a kick-in?
Most of the resistance is in the frame, not in the lock. The metal dustbox that comes with the D241 anchors into the wood frame with three 3 inch screws, and those screws have to reach past the jamb into the structural framing behind it. Fastened only into the jamb trim, the 1 inch bolt gets torn out with the jamb still around it. Route the frame for the 1-1/8 by 2-3/4 inch square corner strike, seat the dustbox first, then mount the strike over it. On the door side, the tapered trim ring spins free to resist wrenching and a shield covers the bolt against a pick pushed through the door gap.
15) I need a deadbolt with no keyhole on the outside, just a thumbturn inside. Is the Falcon D241 that lock?
No. The D241 is keyed on the exterior by design, cylinder outside and thumbturn inside, and there is no non-keyed version of it. For a bolt that is thumbturn operated with a blank plate on the outside face, which is what you want on a back-of-house or exit door that should never open from the outside, the Arrow E60 is a Grade 2 exit deadlock with blank plate by thumbturn function for 1-3/8 to 1-3/4 inch doors.
16) What keyless or electronic deadbolt covers the same door as a Falcon D241?
The Falcon D241 is a mechanical lock with no electronic option. If the goal is code or credential access on the same opening, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium-duty electronic surface deadbolt in brushed steel, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Codelocks CL2210 is the mortise version of that electronic deadbolt.
17) What do I use on a door that needs a thumbturn deadbolt but no key cylinder at all?
The Falcon D241 is a keyed lock, so it always carries a cylinder on the outside face. Where the door only needs to be thrown from the inside, the Arrow E60 is a Grade 2 exit deadlock in a blank plate x thumbturn function for 1-3/8 to 1-3/4 inch doors, which puts a plain plate on the outside and a turn on the inside. The Callan 205S is a Grade 3 one-sided half-bore deadbolt, prepped for a door that is not bored through.
18) What is a lighter-duty alternative to the Falcon D241 for an interior or low-traffic door?
The Falcon D241 is certified to ANSI/BHMA A156.5 Grade 2 for medium-duty commercial service. Where a lighter rating suits the door, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors, the Callan 200S is a Grade 3 single cylinder with square trim, and the Bravura 310B Elite is a Grade 2 traditional round deadbolt in the same cylinder x thumbturn function.
19) Is there a deadbolt with an easier thumbturn for accessible units?
The Falcon D241 uses a standard thumbturn in its cylinder x thumbturn function. The Cal-Royal LSD is a Grade 3 single cylinder deadbolt built with an ADA ergonomic thumbturn for 1-3/8 to 1-3/4 inch doors, which gives a larger inside turn to grip. It sits at Grade 3 rather than the Grade 2 rating the D241 carries, so match it to the traffic on the opening.
20) Which parts look like a deadbolt substitute in a search but will not replace a Falcon D241?
Three that come up alongside it are not complete locks. The BEST 8T is a T Series tubular deadbolt tube component, the bolt assembly on its own rather than a full lock with trim and cylinder. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip. The Falcon D241 ships as a complete lock with a 6-pin cylinder, two cut keys, and a square corner strike with metal dust box measuring 1-1/8 by 2-3/4 inch.
21) What is the difference between a bored deadbolt like the Falcon D241 and a mortise deadbolt?
The Falcon D241 is a bored lock installed through a 2-1/8 inch cross bore and a 1 inch edge bore. Mortise deadbolts need a pocket routed into the door edge instead: the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch in square and round trim, the Dormakaba D900 is a small case mortise deadbolt with a D cylinder in SC keyways, and the DynaLock 1300 Series is a mortise electric deadbolt. None of them drop into a door already bored for a tubular deadbolt.
22) When would I specify a cylinder x blank deadlock instead of a cylinder x thumbturn deadbolt?
A cylinder x blank deadlock is keyed outside with a plain plate inside, so the bolt can only be moved with a key. The Corbin Russwin DL2211, DL3011, and DL3211 are all Grade 1 cylindrical deadlocks in that cylinder x blank arrangement, with the DL2211 and DL3211 listed for 1-3/4 inch doors. The Falcon D241 keeps a thumbturn on the inside, which lets someone retract the bolt from the secure side without a key.
23) The door cannot be bored for a deadbolt. What surface-applied option is there?
The Falcon D241 needs a 2-1/8 inch cross bore and a 1 inch edge bore through the door. Where that prep is not possible, the Codelocks CL200 is a light-duty surface deadbolt with key override that mounts to the face of the door, and the Callan 205S is a Grade 3 one-sided half-bore deadbolt that does not need a through bore. The Detex DX Series is a hinge side locking deadbolt with multi-point security for openings secured on the hinge side.
24) Will a Falcon D241 work on an aluminum storefront or a narrow stile door?
The Falcon D241 is a bored deadbolt with a 2-1/8 inch cross bore and a 1 inch throw bolt, sized for wood and hollow metal doors from 1-3/8 to 2-1/4 inch thick, and its standard strike anchors into a wood frame with three 3 inch screws. Narrow stile and sliding applications generally take a different bolt geometry: the International Door Closers DH-1821 is a hook bolt deadlock with a flat faceplate, and the DL-4511 and DT-1851 are deadlatch locks with flat faceplates for that style of prep.
25) What finishes does the Falcon D241 deadbolt come in to match existing door hardware?
Five finishes: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Every one of them is available with either the G or C keyway and with any of the three cylinder builds, so finish never limits your keying choice. For a commercial building being standardized, 626 satin chrome is the usual default and the one that matches most existing lever and exit hardware already in the field.
26) I need a deadbolt with decorative trim for a residential-facing entry, not utilitarian commercial trim. What are the options?
The Falcon D241 uses a free-spinning tapered trim ring in commercial finishes such as 626 satin chrome and 613 satin bronze oil-rubbed. For a decorative face, the Bravura 310RC Elite and 310SC Elite are Grade 2 cylinder x thumbturn deadbolts in contemporary round and square trim, the Bravura 910005 is a Grade 2 rectangle trim single cylinder, and the Emtek #11 Tuscany is a lost wax cast bronze deadbolt in the same cylinder x thumbturn function. The Brinks Raleigh E2401 and Mendocino E2402 are single cylinder deadbolts with a 4-way adjustable backset in round and square trim.
