Recycled Predator Guard with Copper Portal for Bluebird Houses

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. 

Copper Portals are also available without the predator guard, in five entry sizes!
