Keeps squirrels away from your post mounted feeders with Woodlink's 4x4 Post Baffle. Measuring 20 inches across, this baffle is effective enough to prevent many predators from accessing your feeders as well. Installation is simple, simply wrap the baffle around a post and install a screw on all four sides of the post using the welded brackets around the baffle. This baffle has an attractive powder-coating which will prevent rusting. To prevent squirrels from jumping over the baffle, it should be installed at least 4 to 5 feet above the ground.
