Strainer

Strainer is a device used to tighten and maintain tension in fence wire, especially in high-tensile or electric fencing systems. It works by pulling the wire tight and holding it under consistent tension so the fence stays secure and effective over time.

Strainers are typically installed along the fence line—often at corners, ends, or mid-span—and can be adjusted as the wire stretches or changes with temperature. By keeping proper tension, they help prevent sagging, improve conductivity in electric fences, and extend the life of the fence.
