Hi laneh76,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
Hopefully some of our other members with the shower door will jump in with some info for you soon. Also so it would help if we knew what unit you have. I also deleted the other post you made in different areas as we do not allow duplicate posting.
Be sure and check out our
Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum.
Jim M
