This squirrel stopper is specially designed for outdoor wooden poles, securely mounting on 4 x 4 in. posts or round wooden poles with diameters ranging from 3.4 to 4.6 in. Given that squirrels can jump vertically at least 4 ft. it is recommended to install it 8 ft. off the ground to effectively prevent squirrels from climbing or leaping onto the pole. With a wide 17 in. diameter, the design keeps bird feeders out of reach of squirrels and raccoons, ensuring birds can feed undisturbed. Constructed from durable metal, it offers excellent strength and resistance to tearing or breaking, reliably withstanding animal attempts to steal food over time. The weatherproof surface treatment ensures it withstands harsh outdoor conditions like rain, wind, and snow, making it suitable for gardens, backyards, parks, and other outdoor spaces with all-weather protection. Installation is simple and tool-free, featuring 4-detachable panels that allow quick assembly without specialized skills or extra tools, saving installation time.
