Squirrel Proof Bird Feeder S Poles stop squirrels and make Squirrel Proof Bird Feeders. This Squirrel Proof S Poles series has a Slot & Pin design to securely connect their pole sections together. When the pole sections are slipped together to make the pole, these slots & pins align with one another. The poles can come with squirrel baffles or raccoon baffles below to stop the squirrels and raccoons from climbing the pole. The Bird Feeder Pole Systems can be bundles of poles, bird feeders, weather baffles above and pole baffles below.
