ABSTRACT:
An improved hurricane tie-down member is formed of a unitary flat metallic preform to restrain roof trusses experiencing high wind conditions by optimally transferring dynamic roof uplift forces from a planar saddle portion to a vertical wall via a pair of side arm members and flat anchor surfaces. In a preferred embodiment, over Kips of shear resistance is provided per tie-down member, and when used in sets of four tie-downs, a highly effective method for pitched roof protection is provided.
