I wanted a cable clip to attach my network cables to the wall, but I dont like how most cable clips have the screw / nail hole off to the side making an already ugly cable attached to the wall even more of an eye sore.  I have tested and used this clip with cat5 through cat8 cables and all fit good, but i cant guarantee that it will fit every brand out there. All cables I tested with were between 5 and 6mm, although the 5mm cable just barely holds in place. I designed the screw hole around a standard 6 x _ Drywall Screw.
