Three large clear plastic chambers hold a generous 8 pounds of seed and each one can be removed easily and independently for filling and cleaning. Six individual feeding ports encircle the feeder giving you the option to hold large seed such as sunflower or by flipping the opened ports down you can convert it to hold thistle seed. The large 12" brown plastic dome keeps squirrels at bay and minimizes wet seed in the collecting tray during weather. A 2" round hanger sits atop the dome for easy hanging and stability. Overall height 18".
