I wanted to use this trunking for the cables (power + hdmi) coming out of my ceiling mounted projector. But I'm renting and the ceiling is covered with... wallpaper. So I'm afraid of damaging the wallpaper the day I move.
I'm thinking about a safer solution: some sort of hooks or curved nails supporting the cables, located every 20cm or so along a line from my projector. Are there any kind of nails that could do the trick?
