This 19.5 in. oversized squirrel baffle features a widened design. Even if squirrels climb onto the feeder pole, they will struggle to reach the edge of the baffle, tend to fall off easily and never get close to the bird feeder. Crafted from high-strength, chew-resistant polycarbonate material with a thickness of 3mm, the baffle can resist gnawing damage from squirrels and avoid mess caused by material breakage. Thanks to its generous dimensions, squirrels cannot climb up from below. If they jump onto the baffle from high places nearby, they will not only find it hard to stand firm, but the baffle, which hangs on the pole like a collar, will sway under stress, causing the squirrels to lose their balance and slip off. This effectively prevents any access to the bird food inside the feeder. The baffle is rust-proof, making it more suitable for humid or corrosive environments than ordinary metal alternatives, and it holds up well against rain and snow. Meanwhile, the material is resistant to high and low temperatures, so it will not deform, warp or crack due to sun exposure or squirrel impacts, ensuring long-term outdoor use. It is compatible with feeder poles with a diameter of 16 to 32mm (2/3 in., to 1-1/4 in.). Its 4-piece spliced structure adopts a concave-convex interlocking design for excellent sealing performance. Combined with the seamless connection of the central hook, it can prevent rain and snow from seeping into the feeder below through the gaps.
