This power strip holder is designed to fit any power strip from Clas Ohlson (eg.: https://www.clasohlson.com/se/Grenuttag-med-strömbrytare,-5-vägs-med-5-m-kabel/p/36-4106) but it will probably work for other models as well if scaled properly. The holes are designed for countersunk screws with a diameter of 4 mm and head with a diameter of 8 mm.
