Aspects’ Seed Tube Feeders combine heavy, die cast metal caps, ports, bases and a clear, U.V. stabilized polycarbonate tube to make these feeders an investment that lasts a lifetime. A built in seed deflector in the base allows birds to remove every last seed. Redesigned feed ports on the seed tube model have a raised ridge to divert rainwater and perches are part of the seed port. Add a seed tray to attract more birds and protect the feeder from the elements with an Aspects dome. These new feeders feature a revolutionary, Quick-Clean removable base. To remove the base all you need to do is push the buttons and the base slides easily out! When a seed tray is attached to a feeder, simply remove the base for cleaning with the tray still attached. It is one easy step that makes cleaning your feeders a snap! This feeder has 6 feeding stations, holds 1.75 quarts of seed, and has a 2.75 inch diameter.
