Cut from 5/8" thick solid recycled plastic, this replacement predator guard will fit most bluebird houses. Measures approximately 3-3/8" square with a pre-attached Copper Portal for extra security.
- 1-1/2" entry designed for Eastern Bluebirds
- 1-9/16" entry for Mountain or Western Bluebirds
- Copper Portal pre-attached
- Includes two screws for easy installation
- Made in the USA out of recycled milk jugs!
The Copper Portal will help maintain the entry diameter and prevent predators from chewing around the opening. A predator guard is also useful for repairing a chewed out entry hole, as long as there's enough structure remaining to attach it.
