Step 3
Assemble goal post by first attaching caps to one end of each 12” piece. Then attach an elbow to the other end of each 12” piece. A 6” piece goes into the other end of each of those elbows and connect the two pieces with a tee shaped piece. Through the stem of the tee, insert a 3” piece, then attach an elbow to that. *Note the stem of the tee should be facing backwards, not down.
