Aspects of the disclosure provide a non-welded, clevis-type coupling assembly that provides two sheer planes and, accordingly, increases the load bearing capacity thereof. The assembly includes a coupling plate having a first section, a second section, and a third section. The second section is intermediate the first section and the third section and the first and third sections are oriented at an angle of 90° with respect to one another. The coupling plate includes a contiguous opening extending there through having a first part and a second part. The first part has a first dimension and the second part has a second dimension that is larger than the first dimension.
