The Quick-Clean® Big Tube Feeder accommodates sunflower, safflower, and a range of specialty seed blends, and it uses a clear UV stabilized polycarbonate tube paired with heavy die cast metal caps and bases for long term durability. Its Quick Clean base removes easily without tools even when a seed tray is attached, and the built in seed deflector helps birds access every seed. The metal cap lifts and pivots for convenient filling and cleaning, and the feeder is supported by a lifetime guarantee.
