Dormakaba 74989-000-01 – Frequently Asked Questions

1) What does the Dormakaba 74989-000-01 tailpiece kit actually do in an LFIC knob lock?
It is the mechanical link between a Corbin Russwin large format interchangeable core cylinder and the knob lock mechanism. The core turns the tailpiece, the tailpiece drives the lock. If a knob keys smoothly but nothing retracts, a worn, wrong-length or missing tailpiece is the usual culprit, and the 74989-000-01 is the Dormakaba part that restores that engagement without replacing the lock or the core.
2) Will the Dormakaba 74989-000-01 tailpiece work with a small format interchangeable core?
No. The 74989-000-01 kit is built for Corbin Russwin large format interchangeable core (LFIC) knob cylinders. SFIC cores use a different core geometry and tailpiece, so this kit is the wrong part for an SFIC housing. Confirm the core you are holding is LFIC before ordering.
3) Can I use this Dormakaba tailpiece on a Corbin Russwin mortise or rim cylinder?
It is specified for LFIC knob cylinders, not mortise or rim. Mortise cylinders drive a cam and rim cylinders use a flat rim tailpiece, both different parts. For a knobset with an interchangeable core, the 74989-000-01 is the right family; for mortise or rim, order the tailpiece or cam made for that cylinder type.
4) Is the 74989-000-01 a genuine Dormakaba part for Corbin Russwin hardware?
Yes. Corbin Russwin is a Dormakaba brand, and 74989-000-01 is the factory tailpiece kit for their LFIC knob cylinders. For institutions standardizing on Corbin Russwin keying, using the OEM tailpiece keeps the cylinder-to-lock engagement to the original tolerances rather than relying on a generic aftermarket blade.
5) Do I have to replace the whole lockset if the tailpiece on my LFIC knob is broken?
No. A broken or worn tailpiece is a component-level repair. Swapping in the 74989-000-01 kit restores actuation and leaves the knob, chassis and core in place, which is why it is a common stock item for maintenance shops running Corbin Russwin knob hardware across a building.
6) Is this tailpiece kit rated for commercial door traffic?
The 74989-000-01 is a commercial-grade part, catalogued for commercial rather than residential use, and it is used in offices, schools, healthcare, government buildings, retail and multi-tenant residential. Property managers keying a whole building on Corbin Russwin LFIC knobs can use the same part number across every one of those doors.
7) Is this one part number, or do I have to pick a size or finish?
There is nothing to specify. The Dormakaba tailpiece kit ships as a single configuration under part number 74989-000-01, so there is no length, finish or handing option to choose on the order.
