The ideal way to fix the insulators R8 to wooden posts. They can be screwed directly into wood without the need to pre-drill a hole. Either a Phillips screw driver or, much easier, a cordless power drill are the required tools. There are four small holes in each corner of the insulator (R8) to allow for knots or cavities in the wood. Two are required per insulator, one at the top and one at the bottom.
