Porcelain Donut Insulator White
Porcelain Insulators normally are not recommended for ends on the higher tension fences. They have a tendency to break before the wire. There are a number of special applications where porcelain is used, including a lag screw holding a porcelain donut to a sharp dip or rise post. A set of donuts bolted between strips can be tied to an anchor in a sharp dip to eliminate a dip post.
