I'm working on another "tip" or application for this concept. Just wanted to share that HD in my area doesn't carry an "S" hook that is wide enough to hang on a 2 inch square wooden member on a trellis, or a 2x6 (what I'm working with). Lowe's DOES carry an "S" hook that can hang from that size member.
