Ordering instructions:

 

​The code above can be used together with the text and the information on the type of circuit. The text and type of circuit is also sufficient, in which case Twoy determines the length. Please also let us know the height of the mounting poles measured from the base of the mounting foundation, and where you wish the feeding cable to be connected.
