Dorma, a German door technology company, merged with the Swiss group Kaba in 2015. The group has traded under the name dormakaba since 2016. Units installed years ago may still carry the Dorma name, while current products use the dormakaba name. For service the practical point is the model number on the unit, which tells us what it is, how it works and which parts apply. Send us a photo of the nameplate and we will tell you what we can service.
