1-3/4 Qt. Capacity Seed Tube, 6 feeding ports. Aspects' Seed Tubes carry a Lifetime Guarantee because they use the best materials available. Heavy die-cast metal caps, ports and perches and a clear UV stabilized polycarbonate tube combine to make Aspects Tubes an investment that last a lifetime. A built-in seed deflector in the base allows birds to remove virtually every last seed. The metal cap lifts and pivots easily for filling and cleaning. Add a seed tray to attract more birds and protect the feeder from the elements with a weather dome.
