Birds Choice wire cage to keep out the squirrels, grackles, starlings and other big birds. Comes with hardware to attach tube feeders, suet feeders or other feeders to the base, which also serves as a perching plate. Slotted top to feed the hanger of the feeder through for hanging. Wire is 1 1/2 x 1 1/2
The cage is well made and sturdy. The cost is a bargain. The staff I spoke with are extremely kind, helpful,professional and courteous.
