Recycled 1-1/4" Predator Guards for Nuthatches
Made of recycled plastic! Each predator guard is 9/16" thick, and two square-headed screws are included. The 1-1/4" opening will allow nuthatches and smaller birds to enter their nest box easily, while keeping larger birds like house sparrows out. Attaches quickly to any nest box.
Measures 2-1/4" x 2-1/4" x 9/16" thick.
