A strap having increased column stiffness includes a leading edge and a trailing edge forming a length of the strap, a first outer edge and second outer edge defining a width of the strap, and a first side and a second side defining a thickness of the strap. A crush region is formed in the first or second side, between and generally parallel to the first and second outer edges. The crush region is defined by a thickness that is less than the thickness of the strap adjacent to the crush region. The crush region forms a line along which a bend may be formed in the strap. The bend increases the column stiffness of the strap at least about 67 percent over that of a comparable flat strap. The bend defines an acute angle and an obtuse angle in the strap as viewed in cross-section. |
