The Classic Sunflower or Mixed Seed Feeder with Ring Pull Advantage is a classic tube feeder designed for easy cleaning. Simply pull the ring to disassemble the feeder in seconds without tools. The 16-inch seed tube has a 1-pound birdseed capacity for fewer refills, and the bird feeder has six feeding ports to accommodate multiple birds at once. It works with a variety of seed types, including sunflower seed, mixed seed, peanut chunks, safflower seed, sunflower kernels and cracked corn. The ports protect the tube from squirrels, and the metal perches cannot be chewed by squirrels. For additional durability, the seed tube is made from UV-stabilized polycarbonate that resists discoloration over time. This feeder either can be suspended from its stainless steel bail wire or pole mounted. It measures 2-1/2 by 5-1/2 by 20-1/2 inches. Made in the USA.
