Overview

The Heavy-Duty Straight Fence Post Extenders provide an efficient, economical way to increase the height of existing residential, agricultural, and commercial fencing without replacing posts. Standing 23.5 inches tall, each heavy-gauge steel extension arm features four integrated snap-in wire loops that securely hold barbed wire, tension cables, chicken wire, or safety netting up to 1/2" in diameter. Engineered for quick one-piece mounting onto wooden fence posts, walls, or railings, these post extenders effectively deter deer and wildlife, stop dogs from jumping over fences, and reinforce property perimeter security.
