Help maintain entry holes on your birdhouses. Copper portals prevent predators from chewing or pecking around entry holes to enlarge them. Portals can also be used to repair a chewed entry hole (so long as there's enough wood left to attach the plate), or reduce the size of an existing entry hole.
  • Four screws are included
  • 2" square plate 
  • Available in 5 different entry hole sizes:
    • 1" for House Wrens
    • 1-1/8" for Chickadees
    • 1-1/4" for Nuthatches, Tufted Titmice
    • 1-1/2" for Eastern Bluebirds, Carolina Wrens, Tree Swallows
    • 1-9/16" for Western & Mountain Bluebirds

Please note: copper portals and their screws are not individually bagged.
