5 Inch Offset Fat Man T-post

Maximum Clearance. Total Flexibility. Zero Shorts.

The Iron-Wood 5-Inch Offset Fat Man T-Post Insulator is the ultimate solution for fence lines that demand both extra wire clearance and full positioning flexibility. It clamps 360° around the T-post and can be positioned at any angle around the post — so you can run wire in any direction without being locked into a single orientation. Then the 5-inch offset pushes your hot wire well away from the post, eliminating shorts from vegetation, post contact, or livestock pressure.

Secure it with a standard cordless drill and single bracket. Proudly made in the USA and built to outlast every plastic insulator on the market.
