Additional Tools Required:  Drill

Installation: pick a location for each hole that is not directly over a stanchion or you may encounter obstacles.


Drill a hole through both sections with the smaller #25 drill bit.

In most installations, you want to be sure to hold the drill straight and level so that the rod will be straight.  If you are off a bit, the rods may be bent after installation. 


Because of the tap length you will have to re-drill the top hole with the larger 3/16 bit to accommodate the tap shank so that the tap will reach the bottom hole to be threaded. 


Thread the bottom hole with the tap. 


Insert and thread the threaded rod.  When all rods have been installed, thread monofilament line through the hole on top, tension slightly, tie knots.
