Corbin Russwin 863F058 – Frequently Asked Questions

1) Will the Corbin Russwin 863F058 tailpiece work on a 1-3/4 inch commercial door?
Yes. The 863F058 LFIC tailpiece covers door thicknesses from 1-3/8 inches through 2 inches, so a standard 1-3/4 inch commercial door sits in the middle of its range. Older 1-3/8 inch interior doors and thicker 2 inch openings are both covered by the same part.
2) Does the Corbin Russwin 863F058 tailpiece fit both 6-pin and 7-pin cylinders?
It handles both. The 863F058 is built for 6-pin and 7-pin LFIC cylinder configurations, so you do not need to order a separate tailpiece when your facility runs a mix of pin counts in the same Corbin Russwin core system.
3) What exactly is a tailpiece, and is the cylinder or core included with the 863F058?
The tailpiece is the flat driver bar that runs off the back of the cylinder and transfers the key turn into the lock's retractor. The 863F058 is that driver part on its own, a replacement component for Corbin Russwin LFIC cylinder assemblies. It is not a cylinder and not a core, so if you need the lock to key at all you still need the LFIC housing and an interchangeable core.
4) My opening uses a full size interchangeable core, not a large format Corbin core. What should I order instead of the 863F058?
The 863F058 is built to the LFIC standard and is intended for Corbin Russwin 6 or 7-pin cylinder configurations, so it is not the part for an FSIC opening. For full size interchangeable core work, the Schlage 20-057 is a 6-pin FSIC rim cylinder supplied with a convertible tailpiece cam, and the Schlage 20-057-C is the FSIC core itself in a C keyway. Confirm which core format is already in the housing before ordering a driver bar.
5) Is the Corbin Russwin 863F058 a cylinder, or do I still need to buy a core?
The 863F058 is only the LFIC tailpiece - the flat driver bar that transmits rotation from a large format interchangeable core into the lock. It is a replacement part, not a keyed cylinder, so it carries no core, no keyway and no keys. If what you actually need is a keyed interchangeable core, that is a different item class: the BEST 1CB Peaks 150 Series interchangeable core cylinder or the BEST 1CDF drill resistant 7-pin brass 150 Series core are keyed cores, and the Schlage 20-057-C is a full size interchangeable core in a C keyway. Order the tailpiece when the core is good and the driver bar is wrong, bent or the wrong length for the door.
6) I'm replacing a worn tailpiece on a Corbin Russwin LFIC lock. Do I have to pull the whole cylinder?
No full cylinder swap is needed. The 863F058 is a direct replacement part for the assembly, so you pull the core and change the tailpiece rather than buying a new cylinder. That is the point of the large format interchangeable core design: cores and drive parts come out without replacing the lock body.
7) Do I need a different tailpiece if the door is thicker than standard?
Only if it exceeds 2 inches. The 863F058 is sized to drive through doors from 1-3/8 inches up to 2 inches thick; anything beyond 2 inches falls outside what this tailpiece will reach, and you'd need a longer Corbin Russwin tailpiece for that opening.
8) I need a rim cylinder with the tailpiece already on it rather than a loose tailpiece - what are my options?
The 863F058 ships as a standalone LFIC tailpiece for 6 or 7-pin Corbin Russwin cylinders and assumes you already have the cylinder body. If you want a complete rim cylinder with its cam supplied, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The vertical versus horizontal choice is set by the exit device or rim lock you are driving.
9) My door is thicker or thinner than the 1-3/8 to 2 inch range - is there a cylinder that handles narrow stile or thin material?
The 863F058 tailpiece is sized for door thicknesses of 1-3/8 inch to 2 inch, which covers most commercial wood and hollow metal doors. For thin material such as aluminum stile work, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin cylinder in the 4036 Series rated from a 1/2 inch minimum door thickness. That is a complete mortise cylinder rather than a driver bar, so it is a different scope of work.
10) Will a Kaba Ilco universal cylinder work in place of the Corbin Russwin 863F058?
No - those solve different problems. The 863F058 is a Corbin Russwin LFIC tailpiece, an internal driver component for 6 or 7-pin interchangeable core cylinders. The Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. Those are keyed cylinder bodies for knob and lever locks, so specifying one does not give you the interchangeable core driver bar the Corbin housing needs.
11) We are standardizing a campus on interchangeable cores. Does the 863F058 lock us into a specific core family?
Yes, in practical terms. The 863F058 is a genuine Corbin Russwin commercial part built to the Large Format Interchangeable Core standard for 6 or 7-pin cylinders, so it belongs to a Corbin LFIC program. If a building is instead standardized on BEST small format cores, the parts list runs to items like the BEST 1C5 standard 5-pin cylinder core or the 1CB Peaks 150 Series interchangeable core. Decide the core platform per building first, then buy driver components to match.
12) Is the 863F058 tailpiece suitable for high-traffic commercial buildings, or is it a residential part?
It's a commercial part. The 863F058 is built to commercial application standards and is used in office buildings, schools, hospitals, municipal buildings, retail, warehouses and multi-tenant residential. For facilities standardizing on Corbin Russwin LFIC, stocking a few of these covers 6-pin and 7-pin openings across the 1-3/8 to 2 inch thickness range.
13) Is the Corbin Russwin 863F058 an aftermarket part or a genuine factory component?
Genuine. The 863F058 is an authentic Corbin Russwin cylinder part, made to the factory's tolerances so it seats and drives correctly in Corbin Russwin LFIC hardware. Model number to order by is 863F058.
14) I am servicing a key-in-lever opening, not an interchangeable core one. What cylinder covers that?
The 863F058 is the tailpiece for Corbin Russwin LFIC cylinders in 6 or 7-pin configurations and belongs in an interchangeable core assembly. For a conventional key-in-lever lock, the Falcon A23161-05 G is a key-in-lever cylinder from the Q330 Series with a 6-pin G keyway, keyed different, and supplied with two cut keys. It is a keyed cylinder ready to install rather than a replacement driver component.
15) Can I use a Medeco lazy motion rim cylinder with the Corbin 863F058 tailpiece?
Those are separate systems. The 863F058 is a Corbin Russwin LFIC tailpiece made to Corbin tolerances for 6 or 7-pin interchangeable core cylinders. Medeco lazy motion rim cylinders come with their own driver arrangement for the lock they retrofit - the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Match the tailpiece to the cylinder family it was made for.
