On a sky installation we have in our house the cables exits through the wall via a rubber "bung". Any one know what they are called and where you can buy them?
If its Sky+/HD Twin cable (2 Cables bonded together) as opposed to 1 or 2 individually run cables the 7mm Grommet won't fit over it. Unless you cut down the grommet, Then it'll pinch onto the cable.
