Got tired of taking this back to dealer, although they repaired it free. Used cable ties to hang the end (heavy) slat. One goes around the bar, like a show curtain hanger; and a second one goes through that cable tie and the hole at the top of the slat. Top one is slack; bottom one is barely snug.
This also breaks about once a year; but cable ties are cheap, and I always keep some in my tool bag.
