Fast to install and built to stay put. The Slide Over Pinlock T-Post Insulator (ITDB) is designed for producers who need a reliable, adjustable insulator that goes on quickly and holds firm under the pressure of high tensile fencing. Slide it onto the post, lock it in place with a single pin, and move on—no fumbling, no tools required.
The large flange design keeps your wire well clear of the post, preventing shorts and arcing that rob your fence of voltage. Heavy cross-sections throughout the insulator body withstand the constant tension of high tensile wire without deforming or cracking over time. Molded from high-density polyethylene with carbon black for superior UV resistance, these insulators perform in any climate—from scorching summer heat to deep winter cold.
Compatible with the most common T-post sizes used in livestock fencing, these insulators are a dependable choice for permanent paddocks, cross fences, and perimeter lines alike.
