This my first post so bare with me. What I used was a grounding strip from a electrical panel. I mounted these in the top, sides and bottom of my homemade spray booth. I then used heavy copper wire with various clamps that I mounted to the heavy wire. the other end i placed into the ground strip and tightened the wire with the screws in the strip. I can now bend the copper wire to any desired position and spray away I have pictures if this will help. I just love this site and I'm doing a lot of searching and learning a lot from the experts.
