Woah... I don't know if your joints are going to cut it. I'm sure if you tried you could push one of the horizontal pieces down about a centimeter. Is there anything but those brackets holding the stand together?
The light hanger is really nice though. How much did the rod cost?
Glue, and i used 4" pan heads to toe screw each joint also. Read the thread. I know what im doing.
The first time I bought the rod I paid 3$ a foot, and bought two 4' lengths at my local Rona
This time, I paid .30$ per foot, and bought two 5" lengths from work.
