Corbin Russwin 334F23-8 – Frequently Asked Questions

1) Will the 334F23-8 retainer work with a small format interchangeable core rim cylinder?
No. The 334F23-8 is built for Corbin Russwin Large Format Interchangeable Core rim cylinder configurations. SFIC housings use a different core footprint and retention, so this retainer is the wrong part for them. For an SFIC-style core itself, BEST small-format cores like the 1C5 five-pin are the separate product line to look at.
2) My Corbin Russwin rim cylinder tailpiece keeps slipping out, is this the fix?
That is exactly what the 334F23-8 addresses. Tailpiece retention is its only job, and a worn or missing retainer lets the tailpiece back out so the key turns without driving the exit device or rim lock. Replacing it restores engagement without pulling the whole cylinder assembly out of service.
3) If the whole rim cylinder needs replacing instead of just the tailpiece retainer, what complete rim cylinder can be used?
The Corbin Russwin 334F23-8 is a replacement part only - an LFIC rim tailpiece retainer that holds the tailpiece in a Corbin Russwin large format interchangeable core rim cylinder. When the cylinder body itself is being replaced rather than repaired, complete rim cylinders include the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam and two keys, the Schlage 20-022 with a horizontal tailpiece cam and two keys, and the BEST 12E Series dummy rim cylinder measuring 1-5/32 inch in diameter for openings needing a non-keyed rim plug.
4) Is a Schlage 20-057 FSIC rim cylinder an equivalent to the Corbin Russwin 334F23-8?
No. The 334F23-8 is a tailpiece retainer component for Corbin Russwin large format interchangeable core rim cylinders, not a cylinder. The Schlage 20-057 is a complete 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish. Those are assemblies or cores; the 334F23-8 is the small retention part inside a Corbin Russwin rim cylinder.
5) Is this an OEM Corbin Russwin part or an aftermarket copy?
Genuine OEM. The 334F23-8 is an authentic Corbin Russwin cylinder component, so it drops into the 334F23-8 position in compatible Corbin Russwin cylinder assemblies without fitting or modification.
6) Do I need this retainer when I rekey or swap out an LFIC core?
Core swaps and rekeying don't normally consume the retainer, but it is the part that keeps the rim tailpiece captive in the housing. If the tailpiece is loose or falling out after a core change, or the retainer was lost during service, this is the piece to replace so the cylinder keeps driving the lock properly. It suits LFIC rim applications, where core removal and rekeying are routine.
7) Can I use this retainer to convert a standard Corbin Russwin rim cylinder into an interchangeable core one?
No. The 334F23-8 is a retention component for LFIC rim cylinder assemblies, not a conversion kit. Converting a conventional rim cylinder to interchangeable core means changing the cylinder itself. For an interchangeable core cylinder, options in that class include the BEST Peaks 1CB 150 Series core or the BEST 1CDF drill resistant 7-pin core.
8) We are rekeying rather than repairing - do we need the 334F23-8 or an interchangeable core?
Rekeying an interchangeable core system is done by swapping the core, not the retainer. The Corbin Russwin 334F23-8 is the LFIC rim tailpiece retainer, a mechanical part that keeps the tailpiece seated in the cylinder assembly. For core swaps, interchangeable cores include the BEST 1C Series standard 5-pin cylinder core, the BEST Peaks 1CB 150 Series interchangeable core, and the BEST 1CDF drill resistant patented 7-pin brass 150 Series core.
9) The opening uses a mortise cylinder, not a rim cylinder - what should be ordered instead of the 334F23-8?
The Corbin Russwin 334F23-8 is specific to rim cylinder assemblies, retaining the rim tailpiece in a Corbin Russwin LFIC rim cylinder, so it has no role in a mortise prep. For mortise applications, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder listed as Grade 1 with a 1/2 inch minimum door thickness.
10) Will the 334F23-8 work on a key-in-lever or key-in-knob lock?
No. The Corbin Russwin 334F23-8 is a rim tailpiece retainer for large format interchangeable core rim cylinders, a different cylinder format from key-in-lever and key-in-knob cylinders. For those locks, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with two cut keys, the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. The Kaba Ilco 1579 is a knob and lever cylinder made for Sargent locks.
11) For a residential deadbolt or handleset rim cylinder, is the 334F23-8 the right part?
No - the Corbin Russwin 334F23-8 is a commercial cylinder replacement part for Corbin Russwin LFIC rim cylinder assemblies. Rim cylinders built for deadbolts and handlesets include the Medeco 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, and the Medeco 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
12) On an aluminum storefront with an Adams Rite deadlock, does the 334F23-8 apply?
It does not. The Corbin Russwin 334F23-8 serves Corbin Russwin LFIC rim cylinder assemblies. Storefront deadlock trim comes as cylinder pulls: the Adams Rite 4024 is a cylinder pull with trim plate mounting for the MS1847 deadlock and deadlatch, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the Adams Rite 5017 wood door deadlock and deadlatch.
13) Is the 334F23-8 rated for commercial door hardware use or just residential?
Commercial. It is classified as a commercial door hardware part and is used in Corbin Russwin LFIC rim cylinder installations across offices, schools, healthcare, government buildings, retail, multi-tenant residential and warehouse facilities.
14) What comes in the package, one retainer or a set?
The 334F23-8 is ordered as the single retainer component under one SKU, 334F23-8. It does not include a core, a tailpiece, or a cylinder housing. If your job needs the tailpiece or a complete keyed cylinder as well, order those separately.
15) What distinguishes the Corbin Russwin 334F23-8 from a loose cylinder sold as a part, like the Emtek CY4?
The Corbin Russwin 334F23-8 is not a cylinder at all - it is the LFIC rim tailpiece retainer that keeps the tailpiece captive inside a Corbin Russwin rim cylinder, sold as a commercial replacement part under model 334F23-8. The Emtek CY4 cylinder is sold each as a cylinder in Emtek's parts range. One repairs a rim cylinder assembly; the other replaces a cylinder in Emtek hardware.
16) Our deadbolts need cylinders as part of the same repair order - what pairs with the 334F23-8 job?
The Corbin Russwin 334F23-8 handles the rim tailpiece retention side of a Corbin Russwin LFIC rim cylinder. For deadbolt cylinders on the same work order, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder listed with a deadbolt function, and the Kaba Ilco 1539 Series is listed with a deadbolt function as a universal key-in-knob and lever cylinder.
