The feeder tube is made of durable 0.25-Inch stainless steel wire mesh that is perfect for 1 pound of peanuts or black oil sunflower seed. The internal seed baffle design ensures that the feed is directed out of the center to the mesh cage so that birds can reach it. The open mesh design keeps the seed level visible at all times. Simply slide the die-cast metal cap up the hanger for quick, convenient filling. Lifetime Warranty against squirrel damage.
