Abstract: A blow-through pivotal sign for preventing damage to advertising structures are the like. The blow-through pivotal sign comprises a signboard attached to a support structure to allow the signboard to rotate along a horizontal or vertical axis. The blow-through pivotal sign also comprises a mechanism for retaining the signboard in a fixed position until a preselected torque due to windload is applied as well as a wind responsive retractor for retracting the retaining mechanism to prevent damage thereto after the signboard has been deflected from the fixed position and is swinging freely.
