My men are damaging down spouts at a condo location with weed whips. It's not really bad, but residents complain and now its on the boards watch list. I am looking for a sleeve that I could slid over the down spouts to protect the ends. NOT plastic or vinyl. Steel? Any suggestions? I have looked but haven't found anything. Thanks. Also, please don't post a response like "tell your guys to be more careful". I've done that and they are.
