Bird Nest Box Hole Plates

These stainless steel hole plates prevent squirrels and other predators from enlarging your bird nest box entrance hole. They can also be used if you want to change the range of birds your box is likely to attract.

Available in sizes of 25mm, 28mm, 32mm and 45mm.

The metal plates have rounded corners and can easily be attached using the pre-drilled holes and screws provided.
