to the wall. On the picture you can find an installation box,

Flush mounted installation boxes

are refered to as “MKxx” or simply “flush

mount installation boxes”. When using the nearly

square flush mount installation box MK1, please pay

attention on the correct orientation of the mounting

holes – they need to be on the vertical axis. The

correctly mounted installation box is shown on the
