Dormakaba 55057-000-01 – Frequently Asked Questions
1) What is the Dormakaba 55057-000-01 part?
It's the inside door reinforcing plate for Dormakaba mechanical lock systems, a genuine OEM replacement part. It mounts on the interior face of the door behind the lock and stiffens the door at the lock mounting point, so the lock body stays properly supported over time.
2) Will this plate work with a non-Dormakaba lock, like a Schlage or Kaba Simplex from another series?
Treat it as a Dormakaba-only part. The 55057-000-01 is an OEM component made to fit supported Dormakaba mechanical lock assemblies, and the hole pattern is specific to those locks. If you're servicing another manufacturer's lock, get that manufacturer's own reinforcing plate instead of trying to adapt this one.
3) Is the 55057-000-01 reinforcing plate rated for commercial door use or is it residential hardware?
Commercial. The 55057-000-01 is built to commercial application standards and is used in offices, schools, healthcare facilities, retail, warehouses, multi-tenant residential buildings, and government properties.
4) I'm rebuilding a Dormakaba mechanical lock, do I need the reinforcing plate or just the lock parts?
If the existing plate is bent, stripped, or missing, replace it. The reinforcing plate is what the lock mounts against on the inside face, and a damaged one lets the lock work loose and wear prematurely. On a rebuild where the old plate is flat and its screw holes are clean, you can reuse it and order only the lock components.
5) Which side of the door does the 55057-000-01 plate go on?
The inside, or interior, face. It's the inside door reinforcing plate, so it sits behind the interior lock components, not on the exterior keyed side.
