Weather rules out most sign frames; the Tempest post-top sign is the outdoor member of the family. It attaches to a Tempest outdoor stanchion with a simple twist and click — no slide-in frame to fight in the wind — and a crew can add, swap, or strike messages across a whole outdoor queue in minutes. Pick a ready-made message like "Keep Safe Distance" or supply custom artwork, in single- or double-sided formats and three sizes: 7-by-11, 8.5-by-11, and 11-by-14. The Tempest stanchion itself is sold separately; paired together they make a complete outdoor sign unit. SKU 80-1130TV/P9S.
