Gallagher Equifence is probably one of the safest horse fencing wires on the market. The core consists of a 2.5 mm galvanized iron wire that is coated with 5 mm plastic material with embedded polymer that conducts the current. With its white and orange colors and a total thickness of 7.8 mm, it is highly visible and gentle on the horses, while at the same time having excellent conduction properties.
