Squirrels will see the food through the front acrylic panel and can open the hinged lid to access the food while sitting on the projecting platform (5" sq.). The lid closes itself to keep out rain and snow. Mounts to tree or post with two plated deck screws (included). Two pieces of copper protect the wood on either side of the acrylic panel.
