such that the second reinforcing strap extends longitudinally along the first reinforcing strap,

wherein over at least a portion of the length of the reinforcing straps, the second reinforcing strap has an average thickness
between the inner and outer surfaces of the second reinforcing strap that is larger than the average thickness of the first
reinforcing strap between the inner and outer surfaces of the first reinforcing strap,
