The Triple Tube Deluxe is 17-1/2", has six feeding stations and holds up to 4 lbs. of seed. You can fill each of the three tubes with a different seed to attract a variety of birds to this one feeder. This Duncraft-brand feeder has our durable metal cap, base, and seed ports –- now in a nature-green color. The tubes are recycled resin, more durable than ordinary plastic. We recommend the optional 10-1/2" Super Seed Tray (no. 187) to catch seeds and provide perching for larger birds. This feeder is endorsed by the National Audubon Society.
