Predator Guard w/Copper Portal, Kettle Moraine

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 wood remaining to attach it. 

Made from 7/8" thick solid cedar, this replacement predator guard will fit most bluebird houses.  Measures approximately 3-3/8" square with a pre-attached Copper Portal for extra security.
