An organization I belong to bought and installed 22 granite posts. It is (was) our intention to install black plastic chain between the posts. We have not done it yet. We also will be mounting small plaques on some of the posts.

Our supplier cautioned us that if we were to drill into the posts, we should not use a hammer drill, as Dan (I Shoot 308) said, due to a high risk of cracking the post, and to use a rotary drill only.

They also advised to seal the holes to prevent water from getting into the holes and freezing.

FWIW
