Having a window feeder is easy with a pair of metal Window Bird Feeder Hooks for hanging your window bird feeder on. The window feeder hooks extend 7 inch and will hold up to 5 lbs each. The wire white metal frame makes it incredibly tough and stable. The three strong suction cups hold it in place on your window. These window hooks are nice because they hold the feeders out a little from the window. Small tube feeders or Hummer feeders work great here! You can mount two feeders (not included) with each having their own hook and window. Brings the birds close to you, where you can see them!
