I need to drill 4 holes in my Skylon Swoop Tower in order to run some some 14 gauge speaker wire. The diameter of the tower tubing is around 1 7/8 to 2 inches and the tubing is aluminum. The holes I need for the rubber grommets are going to be 9/16's of an inch. My question is: Am I going to be taking away from the structural integrity of the tower by making four 9/16" holes that will be evenly spaced around ten inches apart? Thanks for you help.
