The end piece has a plurality of end piece bores concentrically arranged around the through-hole and extending substantially parallel thereto. A connection board is secured to an end of the rod and includes a plurality of board bores therein which correspond to the end piece bores. Screws extend through the corresponding end piece bores and board bores to connect the board to the end piece, thereby securely connecting the rod to the joint member.Other References
