I was researching Salomon’s adaptor to mount SNS bindings on top of NIS plates, but very few web stores that carried it all had a low resolution images of something black and oblong. It was obvious from description that it was meant to be used to mount SNS bindings to an NIS plate, but I could not understand what benefits it offered. Recently I bought a pair of the adaptors, and hopefully this post would help someone who would like to know more about it.
There is no shortage of articles and videos about installing SNS bindings onto skis. I watched a few such videos, and all of them were missing precision. Some said that the binding needs to be aligned at the ski’s balance point, others – 1 cm behind it. Most instructions don’t specify the drill bit diameter, and those that do, disagree with each other. It took me a while to locate the official word on installing the bindings.What you are looking for is a PDF file called Salomon Technical Manual Nordic. I only found the 2011 edition in a downloadable form, but there is a 2014 edition that can only be viewed in the browser. I am sure that the main concepts stay constant year to year. For example, all bindings in the 2011 edition are specified to have screw diameters of 6.3mm.
I am not going to duplicate the information found in many other online instructions, but will concentrate on what I thought was missing from them. My takeaway from reading the PDF were two points below.
