The horizontal plate may be perpendicular to the upper and lower vertical side plates and may separate the upper vertical side plates from the lower vertical side plates. The horizontal plate and lower vertical side plates may create an upper cavity that receives the vertical post. Meanwhile, the rafter may be positioned on one of the upper vertical side plates and positioned between two of the upper vertical side plates and may be angled at an acute angle relative to the vertical post as well as the upper and lower vertical side plates.
