Fence post extender arms add 32.1" of height to your existing fence to improve privacy and help stop pets from jumping or escaping. This 12-pack of heavy-duty steel barbed wire extension arms is built for outdoor use with a powder-coated finish for rust resistance. A twist-lock ring secures wire, rope, or accessories up to 1/2" diameter, while full-wrap brackets reduce wobble in wind and rain. Designed for flat or surface mounting on wood, concrete, or brick.

Upgrade your perimeter without replacing your fence. These barbed wire arms are sized for consistent height extension across multiple posts, helping you close escape gaps and add a stronger visual boundary around yards, farms, gardens, and outdoor enclosures. Use them to run barbed wire, tension wire, rope, or even string lights where permitted and appropriate for your application. With included screws, expansion bolts, socket, and drill bit, you can install with common tools and keep your fence line stable season after season. Grab yours today.
