Cotter Pins are an economical way to fasten the wire to line posts or spacer battens. Holes must first be drilled in the fiberglass rods or wood. Clip the pin onto the wire, put the 2 legs of the pin through the hole and bend the ends back to the fence wire. These cotter pins are also perfect to use with pre-drilled fiberglass posts. 12.5 gauge or 14.5 gauge class 3 galvanized.
This gauge does not accommodate ½" fiberglass posts
