This peanut feeder is 13 inches tall, has a powder coated platinum finish that won't chip or fade, zinc die cast tops, bases, and ports that will last a lifetime, stainless steel wire that squirrels can't chew, a snug fitting sliding cap that's easy for you to lift but hard for squirrels, a top assembly that's easily removed for cleaning, and a contoured base that keeps seed within reach and is threaded so you can attach an A-6T or OMT seed tray to catch seed and provide extra room for birds! The stainless steel mesh is the correct size for shelled peanuts, peanut mixes or black oil sunflower seed. The feeder attracts woodpeckers and the aluminum perches can't be chewed and don't hurt birds' feet.
