The Last Insulator You'll Ever Buy
The Iron-Wood Fat Man is a permanent electric fence insulator built for wood posts and steel pipe posts. Unlike plastic insulators that crack, fade, and fail under livestock pressure, the Fat Man is engineered to last — and it can be welded directly to steel posts for a truly permanent installation.
Proudly made in the USA, the Fat Man welds directly to steel posts for a permanent, zero-movement installation — or mounts to wood posts with a standard drill and single bracket. Fast, reliable installation that holds up season after season.
