a pair of radiused male extension portions each extending from opposing lateral extents of said curved center portion of the CAP;
wherein each male extension portion of said CAP has a concave side and a convex side;
said male extension portions each having a finite thickness that spans a portion of an arc length of said curved portion of the CAP;
