Top Receptor for Storm-Bar unit. This part in conjunction with its companion part numbers creates a storm-bar. This bar is used for wider rolling shutter applications. Wider shutters have an increased chance of bending in the face of heavy winds. A storm bar is installed in the middle of a wide shutter to combat these winds. The STORMB-FLOOR-CL (floor plate) and STORMB-TOP-REC (Top receiver) are installed permanently, while the body of the storm bar can be stored elsewhere when not in use.
