A smooth surface, the squirrel baffle has a black powder coat finish, and the smooth, non-gripping surface stops squirrels and raccoons from trying to climb on your bird feeder. This allows more wild birds to come to the feeder to feed. Protect bird feeders, anti-squirrel baffles around pole and hanging bird feeders, protect bird feeders and bird houses from attacking squirrels and raccoons. Easy to install, the wraparound squirrel flap features a foldable design that quickly attaches to an existing bird feeder pole or shepherd's hook. Snap open with inward pressure on each side of the seam. Tap the other parts that hold the cover to the bottom of the unit. There is no need to disassemble the bird feeder for installation. For usage recommendations, we recommend placing the squirrel guard 3.5 feet or more above the ground. It is better to use with the Sheepdog Hook.
