Details

From the reference:

Overlapped K Connection Examples. Provide an overlap of lov = 4" – overlap equals a negative gap. The overlap length is measured along the connecting face of the chord beneath the two branches. Projected length of the overlapping branch on the chord: lp = Dbi/sinꝊi = 4/sin55 = 4.88".

Refer to the figure in the reference for additional details.
