EZ3-B: Mounts using a
custom bracket that you place on your 3-inch square pole. We recommend
this style if you live in windy areas.
Will only fit the 3-inch-square Super Systems and Gemini gourd rack pole we offer.
Will help to prevent snakes, raccoons, cats, squirrels, and opossums from climbing your 3”-square pole and predating your martins.
