Aspects' Thistle 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 piece of thistle. Redesigned feed ports on the thistle tube model have a raised ridge to divert rainwater and perches are part of the port. Add a tray to attract more birds, and protect the feeder from the elements with an Aspects dome. These new feeders feature a revolutionary removable base. To remove the base all you need to do is push the buttons and the base slides easily out! When a 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! Brushed nickel finish, 1.25 quart capacity.
