Dormakaba 74425-55-01 – Frequently Asked Questions

1) What exactly is the Dormakaba 74425-55-01 part?
It's a lock housing with an integrated cylinder guard, finished in black, sold as a genuine Dormakaba replacement component for compatible Dormakaba mechanical lock systems. The housing seats the lock cylinder and holds it in alignment; the guard section shields the cylinder against tampering and forced entry. You are buying the housing assembly, not a complete lock and not a cylinder.
2) Does the Dormakaba 74425-55-01 housing come with a cylinder?
No. The 74425-55-01 is the housing and cylinder guard only. It is precision-formed to seat a lock cylinder and keep it aligned for consistent operation, so the cylinder from your existing Dormakaba lock, or a replacement cylinder, goes into it. Plan the job with your cylinder and keying already sorted.
3) Will this Dormakaba housing fit any brand of lock, or only Dormakaba?
Only Dormakaba. The 74425-55-01 is built to original equipment specification for compatible Dormakaba mechanical lock systems, so it is a like-for-like swap on those assemblies and not a universal housing. If your opening has a lock from another manufacturer, this is the wrong part.
4) Is the Kaba Ilco R2800 housing an equivalent to the Dormakaba 74425-55-01?
No. The Dormakaba 74425-55-01 is a lock housing with an integrated cylinder guard, supplied in black as a replacement part for Dormakaba mechanical lock systems. The Kaba Ilco R2800 Series is a small format interchangeable core convertible housing, meaning it is built to accept an SFIC core. If the goal is to restore an existing Dormakaba lock assembly to its original configuration, the 74425-55-01 is the part; the R2800 is chosen when the opening is being set up for a small format IC core.
5) Is the 74425-55-01 rated for commercial traffic or is it a residential part?
Commercial. Dormakaba classes the 74425-55-01 as a commercial-grade component, and it is the part used on office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and municipal buildings. For a property manager standardizing repairs across a building of Dormakaba locks, it is the factory housing rather than an aftermarket substitute.
6) What does the cylinder guard on this housing actually protect against?
The guard is a built-in shield over the cylinder that resists tampering and forced-entry attacks on the cylinder itself, which is the usual weak point on an exterior commercial opening. Replacing a damaged or pried housing with the 74425-55-01 restores that protection rather than leaving the cylinder exposed.
7) I need a cylinder guard for a commercial opening - will an IC core convertible housing give me that?
The convertible housings are described by their core format rather than by guard hardware: the Kaba Ilco R2800 Series is a small format IC core convertible housing and the S26506 is a mortise large format IC core convertible housing in the Schlage size. The Dormakaba 74425-55-01 is the one specified with an integrated cylinder guard, which shields the cylinder against tampering and forced-entry attempts, and it is a commercial part for Dormakaba mechanical lock systems.
8) Is the black finish on this Dormakaba housing an option or the only way it ships?
Black is how the 74425-55-01 is supplied. It is a single-configuration part number with no finish or size choices behind it, so if your other hardware on the opening is black you are matched, and if it isn't you're looking at a visible finish difference on the cylinder guard.
