Dormakaba 118-509978-K 3PK – Frequently Asked Questions

1) What exactly comes in the Dormakaba 118-509978-K 3-pack?
Each package holds three battery holder and screw sets. The 118-509978-K is a genuine Dormakaba battery holder with its matching screw, sold three to a pack so a technician carries spares for more than one unit on a service call.
2) Can a Corbin Russwin ML2000 screw pack be used in place of the Dormakaba 118-509978-K battery holder and screw?
No. The Dormakaba 118-509978-K is a battery holder with its own screw, made for Dormakaba lock hardware. The Corbin Russwin ML2000 screw packs, such as the 429F31 screw packet for the N escutcheon and the 433F77 M and P escutcheon screw pack, are escutcheon fastener packs for the ML2000 mortise lock line and contain no battery holder. They mount trim, not batteries, so they are not interchangeable with the Dormakaba part.
3) Is the Dormakaba 118-509978-K a genuine OEM part or aftermarket?
Genuine Dormakaba. The 118-509978-K is an authentic Dormakaba parts and accessories component, built to the same commercial standards as the lock hardware it supports, which matters if you are keeping an installed system consistent across a building.
4) I need loose fasteners rather than a battery holder assembly - what should I order instead?
If the job only calls for individual fasteners, Corbin Russwin offers single screws rather than an assembly: the 425F86-8 is a flat screw in 8-32 x 3/8 inch for the ML2000, and the 206F57-8 is a strike combo screw for the same ML2000 line. The Dormakaba 118-509978-K is a different item - it supplies a battery holder together with its screw, sold three sets to a package.
5) Between the Corbin Russwin 429F31 and 433F77 screw packs, what is the difference, and does either relate to Dormakaba trim?
Both are Corbin Russwin ML2000 screw packs, split by escutcheon style: the 429F31 is the screw packet for the N escutcheon, and the 433F77 covers the M and P escutcheons. Neither is a Dormakaba component. The Dormakaba 118-509978-K is a genuine Dormakaba installation accessory intended for Dormakaba mechanical lock systems, so trim screws from the ML2000 family do not cross over to it.
6) Is the Dormakaba 118-509978-K battery holder a commercial part or for residential locks?
It is a commercial-duty part. Dormakaba classes the 118-509978-K under commercial door hardware, supporting lock hardware in offices, schools, healthcare, retail, industrial, multi-tenant residential and government buildings.
7) Should a facility buy the 3-pack of Dormakaba battery holders for stock or just one?
If you maintain several Dormakaba openings, the 3-pack is the stocking quantity. Battery holders are the part that fails from corrosion or a stripped screw after repeated battery changes, so keeping three on the shelf means the next service call gets finished on the first visit rather than after a parts order.
