Hi When NTL etc drill through masonry from the outside they have some plastic sleeves which the put in the hole then thread a the cable through. I want to buy some, but not sure what they are called or where to buy. Has anyone any suggestions? Thanks in anticipation
Concur with Un. Remember to angle hole slightly downwards if inside drilling to outside, and if working outside drilling to inside - then a slight upward angle on the hole would be pertinent.
