Our 18" Wrap-around Pole Mount Squirrel Baffle is perfect for mounting on poles that will not come apart. A metal clamp comes with the baffle that you simply screw around the pole with a Phillips head screw driver. The baffle sits on top of the clamp, and stays there. Must be placed at a minimum 4-1/2ft. high (5ft. is better) on the pole. You will need a tall pole so that your feeder bottoms do not hang below the baffle. A little measuring will help. Keep your feeder pole at least 7ft. from a fence, tree or bush, so that squirrels cannot jump horizontally onto the feeders.
