Fence post extender arms add 23.8 in (605 mm) of height to help boost privacy, improve perimeter control, and discourage pets from jumping out. This 8-pack of steel fence height extenders installs on wood fences or masonry surfaces for a clean, stable upgrade. Built from thickened steel with a powder-coated finish, each barbed wire extension arm is designed for outdoor use and quick attachment of wire, rope, or even string lights via the twist-lock ring.

Use these fence extension arms to upgrade yards, farms, gardens, and perimeter fencing without rebuilding your existing posts. The flat/surface-mount design and included hardware make it straightforward to add height where you need it most—along property lines, around pet areas, or near gates. Install on wood with hex screws or on concrete walls with expansion screws, then attach your preferred wire or rope with the twist-lock ring. Grab yours today and reinforce your fence line with a durable, clean-looking height extension.
