Portal Protector 1 1/2 IN (Metal)

A durable metal entrance guard designed to maintain the proper bluebird‑sized opening and prevent unwanted enlargement by other species.

The 1½" Metal Portal Protector reinforces the entrance hole of bluebird nest boxes, ensuring the opening stays the correct size for Eastern Bluebirds. Larger birds, squirrels, and woodpeckers often try to widen nest box entrances, which can compromise nesting safety — this metal portal prevents that damage.

Made from sturdy, weather‑resistant metal, it installs easily on most wooden birdhouses and extends the life of the box while protecting nesting birds.
