Falcon 030739-004-30 – Frequently Asked Questions

1) What does the Falcon 030739-004 throw member actually do inside an SFIC cylinder?
The 030739-004 is the internal throw member for the Falcon RU571 pin cylinder. It transfers the rotation of the core out to the lock mechanism, so it is the piece that makes the key turn actually operate the latch or bolt. If a Falcon RU571 cylinder turns freely with a good key but nothing retracts, a worn or broken throw member is the usual cause and this is the factory part that replaces it.
2) Do I need the 6-pin or the 7-pin Falcon 030739-004 throw member?
It is sold in a 6-pin and a 7-pin version, and you match it to the pin count of the SFIC core in the opening. Pull the core and count the chambers, or check the keying records for the system: a 7-pin SFIC housing takes the 7-pin throw member, a 6-pin system takes the 6-pin. They are not interchangeable in service, so ordering by the core you already have is the safe way to do it.
3) Is this an interchangeable core I can key up, or just a component?
It is a replacement component, not a keyed core. The 030739-004 is an internal part of the Falcon RU571 SFIC cylinder assembly and carries no pinning or keyway of its own. If what you need is an actual keyed SFIC core to rotate into a housing, look at a small format interchangeable core such as the BEST 1C Series 5-pin core or the BEST Peaks 1CB 150 Series core instead.
4) Will this Falcon throw member fit a Schlage or Corbin Russwin cylinder?
No. The 030739-004 is built specifically for the Falcon RU571 pin cylinder and is not a universal throw member. Schlage rim cylinders like the 20-021 (vertical tailpiece cam) and 20-022 (horizontal tailpiece cam) use their own tailpiece arrangement, and Corbin Russwin mortise housings such as the 1070 use cams like the A01 cloverleaf. For those brands you replace the cylinder or order the cam or tailpiece made for that series.
5) If the Falcon RU571 cylinder body itself is worn rather than just the throw member, what complete SFIC core can be used instead?
The Falcon 030739-004 is an internal throw member for the RU571 pin cylinder, so it only restores a housing that is otherwise sound. When the core needs replacing outright, small format interchangeable core options include the BEST 1C Series standard 5-pin cylinder core, the BEST Peaks 1CB 150 Series interchangeable core cylinder, and the BEST 1CDF drill resistant patented interchangeable core, which is a 7-pin brass 150 Series core. The 030739-004 comes in 6-pin and 7-pin configurations, so match the pin count of the core you are servicing.
6) Is a Schlage 20-057 interchangeable core a substitute for the Falcon 030739-004?
No. The Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is a full size interchangeable core in the C keyway. Those are full size interchangeable core products, while the Falcon 030739-004 is a small format interchangeable core throw member that fits inside the RU571 pin cylinder. FSIC and SFIC housings take different cores, so the Schlage parts serve a different prep.
7) Do I have to replace the whole cylinder, or can I just swap this part?
If the housing and core are sound and only the throw member is worn, you swap just the throw member. It is built as a drop-in replacement for the RU571 assembly, so the housing stays in the door and the existing keying is untouched. Replace the full cylinder only when the housing itself is damaged or you are changing keyway systems.
8) For a mortise lock opening instead of an SFIC housing, what cylinder should be specified?
The Falcon 030739-004 throw member serves the RU571 pin cylinder and is not a mortise cylinder. For mortise prep, the Corbin Russwin 1000 Grade 1 Series mortise cylinder is offered in 1-1/2 inch length with an A02 straight cam, the 1070 Grade 1 Series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the 1080 Grade 1 Series is a 1-1/2 inch LFIC 6-pin mortise cylinder set up for Schlage L9000 mortise locks. The Adams Rite 4036 mortise cylinder is a Grade 1 five-pin unit for doors 1/2 inch minimum thickness.
9) What should be ordered for an exit device rim application rather than the Falcon 030739-004?
Rim applications take a complete rim cylinder, not the Falcon 030739-004 throw member. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, each supplied with 2 keys. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, and the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter for openings where no key function is needed.
10) Can a key-in-knob replacement cylinder be used in place of the Falcon 030739-004?
No. The Falcon 030739-004 is an internal throw member for the RU571 pin cylinder in a small format interchangeable core system. Key-in-knob and deadbolt replacement cylinders such as the Kaba Ilco 1539 Series key-in-knob/lever universal cylinder, the 1549 Series key-in-deadbolt cylinder, the 1579 Series knob and lever cylinder for Sargent, and the 1599 Series key-in-knob replacement cylinder are complete cylinders for knob, lever, and deadbolt bodies, a different prep from an SFIC housing.
11) Is the Falcon 030739-004 rated for commercial door traffic, or is it a residential part?
Commercial. Falcon classifies the 030739-004 as a commercial door hardware part, and it is used for cylinder service in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential. For maintenance departments running Falcon SFIC across a campus, it is the kind of part worth holding in both pin counts so a dead cylinder gets turned around the same day.
12) Is this a genuine Falcon part or an aftermarket copy?
Genuine Falcon, supplied through the Falcon Lock Parts program for service of installed hardware. That matters on an SFIC throw member because the tolerances decide whether the core rotates and drives cleanly; an off-spec part can bind or shear under use.
13) Is there a higher-security alternative if the goal is drill resistance rather than restoring an RU571 cylinder?
The Falcon 030739-004 is a commercial-grade genuine replacement throw member that returns an RU571 pin cylinder to original function; it does not change the security level of the core. Where drill resistance and patented key control are the objective, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin brass, in the 150 Series. Medeco retrofit cylinders are another route for residential-style handleset and deadbolt hardware, including the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handlesets and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
14) What is used on an Adams Rite deadlock instead of the Falcon 030739-004?
Adams Rite deadlocks use their own cylinder pulls rather than a Falcon SFIC component. The Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch. The Falcon 030739-004 remains specific to the RU571 pin cylinder.
