I am trying to clamp a tube across the top of my tower to hold light on. I want to get some sort of clamps that will clamp to the tower and to the tube which will house the lights. The tube will be on top of the tower and running at 90 degrees to the tube on the tower. hope that makes a bit more sense.
I have 4 Fusion tower clamps. They are one size fits all. They have rubber spacers to adapt to the required diameter. I found them in the garage when I was doing some cleaning. Throw me a few bucks and they're yours.
