Wall mixers are usually installed on mixer plates, which are subsequently attached to the wall. In Europe, the standard is usually 150 c/c, but in Sweden, this standard is 160 c/c. With new piping, it's easier to use tubes with the right dimensions and then use simple mixer attachments.
Sold in pairs. Use with the cover caps that come with the mixer. Note: around 1 cm of thread will be visible between the hood and the mixer fixing nut (image 2). To make the thread blend in with mixers with another finish, you could buy a matching paint and brush (or spray) the thread.
