Falcon D131P 626 – Frequently Asked Questions

1) I am replacing a Grade 2 deadbolt on a commercial door. Is the Falcon D131 a straight swap?
Usually, if the existing prep is a standard bored deadbolt. The D131 adjusts to either 2-3/8 or 2-3/4 inch backset and covers 1-3/8 to 1-7/8 inch doors, so it lands on most existing preps without redrilling, and moving from Grade 2 to Grade 1 is the upgrade a property manager makes when a door keeps getting hit. Two things will stop it: if the outgoing lock was single cylinder, the D131 has no thumbturn and everyone inside now needs a key, and on a metal frame the three 3 inch dustbox screws are meant for wood.
2) Is the Falcon D131 deadbolt ANSI Grade 1?
Grade 1 under ANSI/BHMA A156.5, 2001, and rated commercial heavy duty. That is the top security grade for auxiliary locks and is what most institutional, government and healthcare specs call for on a bored deadbolt. If the spec on the drawing only calls for Grade 2, the Hager 3214 double cylinder is the Grade 2 option, and Delaney's LU Series double cylinder is also Grade 2.
3) What do I have to specify when ordering a Falcon D131 deadbolt?
Four choices. Cylinder type: P gives you a 6-pin conventional cylinder in the Falcon G keyway, B ships less SFIC so you can drop in your own small format core. Finish: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome or 626 satin chrome, and every one of those pairs with either cylinder type. Keying: keyed different, keyed alike across multiple locks, or none if you selected a less-cylinder option. Then bolt faceplate and strike. Special keying instructions go in the free-text field on the order.
4) Can I order Falcon D131 deadbolts keyed alike across a building?
Yes. Keyed alike is a selectable option, so a run of D131 deadbolts can be ordered on one key for a property or a floor, and keyed different is the standard if you want each opening separate. The conventional cylinder is a 6-pin in the Falcon G keyway. Factory master keying is offered on Schlage C keyway configurations. If your facility already runs a small format interchangeable core system, order the B less SFIC version and pin your own cores so the deadbolts fall into the existing hierarchy.
5) Which deadbolt should be used instead of the Falcon D131 when a key on both sides is not wanted for egress?
Use a single cylinder deadbolt with a thumbturn on the inside. The Dexter DB1000 Series single cylinder deadbolt is the Grade 1 cylinder x thumbturn counterpart, covering a 1-3/8 inch to 1-7/8 inch door thickness range. The Delaney LM Series single cylinder deadbolt is another Grade 1 cylinder x thumbturn option and comes less core for interchangeable core keying. The Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch. The Falcon D131 is keyed on both sides as a double cylinder function, so the inside also requires a key to retract the bolt.
6) What deadbolt works on a door thicker than the Falcon D131 range?
The Corbin Russwin DL3011 cylindrical deadlock is a Grade 1 deadbolt listed for doors 1-3/4 inch to 2-1/4 inch, so it reaches thicker doors than the Falcon D131, which is built for 1-3/8 inch to 1-7/8 inch with a conventional cylinder. The DL3011 is a cylinder x blank configuration, meaning it is keyed on one side with a blank plate on the other, rather than keyed both sides like the D131 double cylinder. The Deltana 7312KA2 double cylinder deadbolt reaches 1-3/8 inch to 2 inch and keeps the key-both-sides arrangement, at Grade 3.
7) What is the closest Grade 1 double cylinder deadbolt to the Falcon D131 for a 1-3/4 inch commercial door?
The Design Hardware D1 Series double cylinder deadbolt is the nearest straight equivalent: Grade 1, double cylinder function, extra heavy duty, sized for a 1-3/4 inch door. The Falcon D131 is also Grade 1 with a double cylinder keyed function and carries ANSI/BHMA A156.5, 2001, Grade 1. Dexter's DB1000 Series double cylinder deadbolt is a second Grade 1 double cylinder option, listed for a 1-3/8 inch to 1-7/8 inch door thickness range, which matches the same span the D131 covers for conventional cylinder applications. Choose the D1 Series when the door is fixed at 1-3/4 inch, and the DB1000 or D131 when door thickness varies across the openings.
8) Which Falcon D131 alternative should be specified when the opening needs a fire rated deadbolt?
The Hager 3214 double cylinder deadbolt carries a fire rating and uses a Schlage C keyway, for doors 1-3/8 inch to 1-3/4 inch. The Hager 3118 is a Grade 1 classroom deadbolt with a fire rating, Schlage C keyway and 6-pin cylinder, over the same door thickness range. The Cal-Royal CRB800 heavy duty single cylinder deadbolt carries a UL 3-hour fire rated latch in a cylinder x thumbturn function. The Falcon D131 is a Grade 1 double cylinder deadbolt on the G keyway, with factory master keying available on Schlage C keyway configurations.
9) Which deadbolt suits an opening that has to release without a key from the inside, where a Falcon D131 would not?
The Arrow E60 exit deadlock is a Grade 2 non-keyed unit with a blank plate outside and a thumbturn inside, for doors 1-3/8 inch to 1-3/4 inch, so the bolt retracts from inside with no key. The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt for a door prepped from only one face. The Falcon D131 is a double cylinder function requiring a key on both sides, which is restricted for egress in many occupancies and should be verified against the code for the facility type before it is specified.
10) What makes the Falcon D131 harder to attack than a standard deadbolt?
Four things, and they are the reason this one gets specified on exterior and high-traffic institutional openings. The bolt is solid sintered steel with a hardened steel anti-saw pin insert. An integrated security shield blocks ice-pick attack at the bolt through the door gap. The trim ring is free-spinning and tapered, so a wrench or pliers cannot grab and twist the outside cylinder. And the metal dustbox anchors into the wood frame with three 3 inch screws, which is what stops a kick-in from splitting the jamb rather than defeating the lock.
11) What else could I buy instead of the Falcon D131 double cylinder deadbolt?
Staying at Grade 1 and double cylinder, the closest peers ZenSupply carries are the Design Hardware D1 Series, which is extra heavy duty and built for a 1-3/4 inch door only, and the Dexter DB1000 double cylinder, which matches the D131's 1-3/8 to 1-7/8 inch thickness range. Stepping down a grade, the Hager 3214, Dexter DB2000 and Delaney LU Series are Grade 2 double cylinders, and the Hager and Dexter both cover 1-3/8 to 1-3/4 inch doors. The D131's differentiator among these is the adjustable 2-3/8 or 2-3/4 inch backset and the Falcon G keyway cylinder.
12) What is the difference between the Falcon D131 and a deadlock like the Corbin Russwin DL3211 or Arrow E61?
The Falcon D131 is keyed on both sides, a double cylinder function, and comes with a 1-1/8 inch by 2-3/4 inch square corner strike with metal dust box. The Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock in a cylinder x blank arrangement for 1-3/4 inch doors, keyed from one side with a blank plate opposite. The Arrow E61 is a Grade 2 single cylinder deadlock prepped for a small format interchangeable core and supplied less core, for doors 1-3/8 inch to 1-3/4 inch. A cylinder x blank deadlock cannot be operated at all from the blank side, so it is not a drop-in for an opening that needs key access from both faces.
13) What replaces a Falcon D131 when the door needs a keypad or credential instead of a key?
The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The Codelocks CL2200 is an electronic surface deadbolt in a brushed steel finish at a medium duty level, and the Codelocks CL2210 is an electronic mortise deadbolt. For multihousing credential access, the Dormakaba Nova-D is an RFID smart electronic deadbolt and the Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Falcon D131 is a mechanical deadbolt with no electronic function, keyed on both sides and supplied with two cut keys.
14) Is a mortise deadbolt an alternative to the Falcon D131, and how does the door prep differ?
A mortise deadbolt drops into a pocket cut into the door edge rather than the cross-bore and edge-bore preparation a bored deadbolt uses. The Dormakaba D900 small case mortise deadbolt is a cylinder x thumbturn unit supplied keyed different on Schlage C keyways. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, in square and round trim, both cylinder x thumbturn. The Falcon D131 installs into a bored preparation with an adjustable 2-3/8 inch or 2-3/4 inch backset, so switching to a mortise unit means a different door machining, not just a different lock.
15) What single cylinder deadbolt matches the Falcon D131 when only the outside needs to be keyed on an interchangeable core system?
The Delaney LM Series Grade 1 deadbolt is a single cylinder less core unit in dull chrome US26D, and the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for doors 1-3/8 inch to 1-3/4 inch. The Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset. The Falcon D131 is offered in a B less SFIC cylinder configuration as well as a 6-pin conventional G keyway cylinder, so a facility already on an SFIC system can stay on it in either the double cylinder D131 or these single cylinder peers.
16) Can I get the Falcon D131 deadbolt to match the finish on the rest of my door hardware?
Five finishes cover it: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Satin chrome, 626, is the one that matches most commercial openings, and it is the only finish offered with the circular drive-in bolt option. All five are available with either the conventional G keyway cylinder or the less-SFIC version, so finish and cylinder type are independent choices.
17) Is the Falcon D131 an electronic or smart deadbolt?
No, the D131 is purely mechanical, key operated on both sides, with no electronics, no battery and no credential reader. If a facility needs audit trail or code access on a deadbolt opening, the Codelocks CL2200 is an electronic surface deadbolt and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with electronic lock override. For a keyed mechanical opening in an institutional building, the D131 is the mechanical answer.
