Quick-Clean Feeders combine heavy die-cast metal caps and bases with a clear UV stabilized, polycarbonate tube to make these feeders and investment that lasts a lifetime. A built-in seed deflector in the base allows birds to remove every last seed. To remove the base all you need to do is push the buttons and the base easily slides out! When a seed tray is attached, simply remove the base for cleaning with the tray still attached. It is one easy step that makes cleaning your feeders a snap!
