400 Sunrise Ave., Suite 270 <br />Roseville, CA 95661 <br />916.755.3571 / MiTek-US.com <br />Design valid for use only with MiTek® connectors. This design is based only upon parameters shown, and is for an individual building component, not <br />a truss system. Before use, the building designer must verify the applicability of design parameters and properly incorporate this design into the overall <br />building design. Bracing indicated is to prevent buckling of individual truss web and/or chord members only. Additional temporary and permanent bracing <br />is always required for stability and to prevent collapse with possible personal injury and property damage.
