Wood & Steel Fat Man

Built to Stay Put — Season After Season

The Iron-Wood Wood & Steel Fat Man is the same heavy-duty insulator trusted on working farms across the USA, purpose-built for wood posts and steel pipe posts. It can be welded directly to steel pipe posts for a permanent, zero-movement installation — or mount it to wood posts with a standard drill and single bracket.

Proudly made in the USA, the Fat Man is engineered to outlast plastic insulators that crack under livestock pressure, fade in UV, and fail when you need them most. One insulator. Two post types. Zero compromises.
