Amador Barn Owl Boxes can be mounted on a tree in different methods, all of which we have available. This method includes a cable and hardware set for effectively hanging the owl house. The advantage is making only 1 actual 1/4” hole in the tree; we recommend this for oaks especially. The hardware set includes the materials for hanging the box, instructions, and metal strapping for keeping the box from swinging due to being attached to the cable only.
