About Iron-Wood

Iron-Wood Insulators began in Missouri, born out of frustration on our family farm. After too many fences ruined by deer and escaped livestock, we designed a better solution—an insulator that works with both wood and steel posts and holds up in real farm conditions.

Family-run. Made in the USA. Built for practical, long-term reliability.
