Curved polycarbonate panels and aluminum support bars form a 39 x 30 x 9 in awning that helps shield your doorway or window from sunlight, rain, wind and snow. The thick PC sheet supports up to 44 lbs, and ABS and PP brackets transfer the load to the wall for stable coverage over the entry area. A seamless surface with an arched profile directs water off the edge to limit pooling and leaks. Four included expansion bolts let you install the canopy on cement, wood or brick walls to cover doorways, windows or shop fronts for exterior use.
