Question about Digitus Flexible Cable Routing with Adjustable Length

I would like to use this with the following Casaria table, https://www.galaxus.ch/en/s14/product/casaria-scrivania-regolabile-in-altezza-desks-24650553?supplier=5413819 , how I'm not sure that it can be attached to back of the table. Does anyone know how wide is the space between the two holes?
