The 17" diameter squirrel-proof dome keeps squirrels from the seed when the feeder is hung on a branch 5 feet or more away from the tree trunk, and 5 feet or more above the ground. The large capacity 1-1/2 gallon bucket means fewer trips to refill. The a la carte dividers provide four seed compartments instead of one. Cardinals, chickadees, tufted titmice, woodpeckers and many other songbirds gather on this circular, full-view patio. Dimensions: 17" H (+ chain) x 17" diameter. Made by Arundale Products.
