I would like to make some neat holes in a light oak effect fitted bedroom dressing table area in order to bring electrical cables/speaker cables up from underneath to appliances on the surface - Radio, speakers, lighted mirror etc. I am trying to find some kind of grommet to finish the holes with so that it looks tidy. Approximate hole size is likely to be between 15 and 25mm diameter. Ideally a polished chrome finish to compliment other door/window accessories. Has anyone solved an issue like this before? Suggestions gratefully received.
