This fence extender set is designed to raise the height of chain link fencing for added security, privacy, and pet containment. It includes 18 galvanized steel extenders with an upgraded Ω bracket design that fits 1.3" to 1.5" round top rails securely. The powder-coated steel construction helps resist rust and weather for long-term outdoor use. Installation is fast with the included hardware and no drilling required. Rounded end caps help keep out rain and debris while giving the fence a cleaner finished look.
