Recycled 1-1/8" Predator Guards for Chickadees and Wrens
Made of recycled plastic! Each predator guard is 9/16" thick, and two square-headed screws are included. The 1-1/8" opening will allow house wrens and chickadees to enter their nest box easily, while keeping larger birds like house sparrows out. Attaches quickly to any nest box.
Measures 2" x 2" x 9/16" thick.
