Arrow 100CR-44-201 – Frequently Asked Questions

1) Does this Arrow tailpiece work with both 6-pin and 7-pin SFIC cores?
Yes, both. The 100CR-44-201 pack supports 6-pin and 7-pin small format interchangeable core configurations, so you can use it whether the facility keys on a 6-pin or 7-pin SFIC system.
2) Does the 100CR-44-201 pack include the cylinder core itself?
No. It is the tailpiece only, sold as a pack. The SFIC core is ordered separately and keyed to your system. If you need an actual interchangeable core instead, a BEST 1C Series 5-pin core or the 1CB 150 Series interchangeable core cylinder are cores rather than drive hardware.
3) What should I order if the lock takes a full size interchangeable core instead of a small format core?
The Arrow 100CR-44-201 tailpiece is built around small format interchangeable core cylinders, so it is not the part for a full size core prep. For FSIC work, the Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the Schlage 20-057-C is a full size interchangeable core cylinder in C keyway with a 643E aged bronze finish. The Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 cam.
4) Does the Arrow 100CR-44-201 tailpiece pack include a cylinder core, or is a separate SFIC core needed?
The Arrow 100CR-44-201 is the tailpiece only - the link between an SFIC cylinder and the lock body on Arrow H Series (excluding 15 and 19 functions) and RK Series locks with 6-pin and 7-pin small format interchangeable cores. The core itself is a separate item. For a small format interchangeable core, the BEST 1C Series standard 5-pin core and the BEST Peaks 1CB 150 Series interchangeable core cylinder are both interchangeable core products; the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass, matching the 7-pin configuration the Arrow tailpiece supports.
5) Which cylinders look like a substitute for the Arrow 100CR-44-201 but will not work on an H or RK Series lock?
Several cylinders carry their own fixed tailpiece and are not interchangeable with the Arrow 100CR-44-201 tailpiece pack for Arrow H Series and RK Series SFIC locks. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same rim cylinder with a horizontal cam; the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece; and the Medeco 1065244 is a 5-pin lazy motion rim type cylinder supplied with an Emtek tailpiece. Each of those is a complete rim cylinder assembly for a different lock interface rather than a service tailpiece for an Arrow SFIC lock.
6) Can the Arrow 100CR-44-201 be used on an aluminum storefront deadlock?
No. The Arrow 100CR-44-201 tailpiece pack is matched to Arrow H Series and RK Series locks with 6-pin and 7-pin SFIC cylinders. Storefront deadlocks use their own cylinder pulls: the Adams Rite 4024 mounts with a trim plate and the 4025 uses through-screws, both for the Adams Rite MS1847 deadlock/deadlatch, while the 4026 five-pin cylinder pull is for the Adams Rite 5017 wood door deadlock/deadlatch.
7) What does a tailpiece actually do in an SFIC lock, and why would I need to replace it?
The tailpiece is the driver between the interchangeable core and the lock body. Turn the key, the core rotates, and the tailpiece transmits that motion to the retractor inside the lock. If it is worn, bent, or the wrong length, the key turns but the latch does not move. Replacing it restores engagement without pulling the whole lock off the door.
8) Is this an OEM Arrow part or an aftermarket tailpiece?
Genuine Arrow. The 100CR-44-201 is an Arrow OEM replacement component, which matters on SFIC hardware because tailpiece length and drive geometry are series specific and a generic substitute often will not seat correctly in the H or RK lock body.
9) Is there a retrofit cylinder option for an Arrow lock instead of replacing just the tailpiece?
The Arrow 100CR-44-201 restores the cylinder-to-lock engagement on H Series (excluding 15 and 19 functions) and RK Series locks running 6-pin or 7-pin SFIC cores. If the goal is to change the keying platform on an Arrow lock rather than service the existing one, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock, which also covers Emtek handleset and deadbolt outside cylinder use.
10) What do I use for a mortise lock prep rather than an SFIC tailpiece?
The Arrow 100CR-44-201 tailpiece pack serves SFIC cylinders in Arrow H Series and RK Series locks. Mortise preps take a threaded mortise cylinder instead: the Corbin Russwin 1000 Grade 1 mortise cylinder is 1-1/2 inch with an A02 straight cam, the Corbin Russwin 1070 Grade 1 housing is 1-1/4 inch 6-pin with an A01 cloverleaf cam, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder with a 1/2 inch minimum door thickness. Cam style and length must match the lock case.
11) For a key-in-lever or key-in-knob cylinder replacement, what is the equivalent part?
The Arrow 100CR-44-201 is a commercial replacement tailpiece for SFIC cylinders in Arrow H Series and RK Series locks, not a key-in-lever cylinder. For cylindrical lock cylinder replacement, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder; the Kaba Ilco 1549 is the key-in-deadbolt version. The Falcon A23161-05 G is a key-in-lever cylinder for RU and T Series in a 6-pin G keyway, keyed different with two cut keys.
12) Will the Arrow 100CR-44-201 work on residential handleset or deadbolt hardware?
The Arrow 100CR-44-201 is a commercial part built for Arrow H Series and RK Series locks with SFIC cylinders. Residential-style handlesets and deadbolts use different cylinders: the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the Emtek CY4 cylinder is sold each for Emtek hardware.
13) Is this tailpiece suitable for commercial and institutional buildings?
It is a commercial-grade part, built to Arrow's commercial hardware standards and used in offices, schools, hospitals, government buildings, retail, warehouses and multi-tenant residential. For a facility standardizing on Arrow H or RK SFIC hardware, it is the service part to stock for lock repairs.
14) Is there a Medeco retrofit cylinder for Arrow locks if I want high security instead?
For a high security route, the Medeco 1065140 is a 5-pin retrofit cylinder listed for the Arrow JL interconnected lock. Note that is a different Arrow platform than the H and RK SFIC locks the 100CR-44-201 tailpiece pack serves, so it is an alternative path rather than a companion part.
15) What is the difference between the Arrow 100CR-44-201 and a dummy cylinder like the BEST 12E?
The Arrow 100CR-44-201 is a functioning service part: the tailpiece that transmits key rotation from an SFIC cylinder to the lock body on Arrow H Series and RK Series locks, so the lock actually actuates on key turn. The BEST 12E Series dummy rim cylinder, 1-5/32 inch in diameter, fills a cylinder hole without operating a lock. Choose the Arrow tailpiece when restoring mechanical function and the dummy when the opening only needs the prep covered.
