Abstract

A wind-resistant elongated spanner includes a display member to be supported longitudinally at opposite ends in the space between opposed extrinsic portal-defining upright structures, such as canopy poles, in display configuration. It has a thin beam configuration core presenting parallel, rectangular front and rear faces having a high aspect ratio. Channel configuration top and bottom rails extend along top and bottom core faces. Metal face panels extend over the front and rear core faces, layers of adhesive being interposed between the face panels and respective front and rear core faces for securement of the faces panels to the core, opposite end faces of the core being uncovered. The display member is supported by mounting members at opposite ends of the display member, each configured for attachment to a pole or other upright structure to provide a channel opening toward the display member for reception of marginal portions of an end of same.
