Our KBW BannerFlex® D3 Banner Bracket may be used to wall-mount banners onto exterior or interior building walls. When utilizing this application, we recommend a special mounting between the bracket and the wall to increase the surface area of the installation.
Most exterior wall installations are brick or other masonry, wood siding or concrete. Because the main casting of the light pole banner hardware is quite small (only about 21" square - 3" x 7" - for our largest model) the wind pressure transferred from the banner to the bracket becomes quite concentrated and puts an extreme force onto a very small area during major wind events. Because the wall is not designed for this type of concentrated force, there is a tendency for the outer edges of the main casting to quickly wear into the surface.
For that reason, we recommend installing our steel plate onto the back of each main casting to provide a larger surface area in order to spread the wind load and protect the wall surface. The plates can be attached by substantial anchors or lag bolts to and/or through the wall, depending on the wall's composition. We recommend using four fastening locations per plate or through the exterior wall.
Please note: For our standard square wall mount plate lead time is 3-5 days. For all our other custom shape plates, please contact a sales representative. We are committed to shipping early whenever possible.
