  • Lightning rods-glass balls?

    Those glass balls were in place to basically burst when lightning would hit the rod it was attached. This giving the homeowner visual confirmation that the rod was hit, and that it provided the protection that it advertised. The balls were then to be replaced as a further monitor of any lightning strike.
