Abstract: A window awning system comprises an awning fabric defining an upper edge with a hollow hem formed therein and a lower edge with grommets. An extrusion mounts on the wall. Apertures in a face portion receive wall fasteners and an outwardly extending C-shaped channel. A hem rope is contained within the hem. The hem and rope are then fed into the C-shaped channel. A pair of hollow wall posts have an inboard wall mounting end and an outboard free end. The inboard end has a flat rectangular plate. Each outboard free end receives an end cap. A perimeter cable has a central section passing through holes in the end caps and attaches to the extrusion by the use of metal wire crimps. A lashing rope passes through each grommet of the awning fabric and encompasses the perimeter cable with each pass for securement of the fabric from below.
