Each J channel has a side with open slots for screws. You just put that edge against the inside of the fascia and I just used 3 screws for each section. Look at the other videos in the playlist. There’s a bunch!
@@naturaljah100It’s ok but I really don’t have any plans for it. I took some 1 x 2 pieces of wood, laid them around a piece of J Channel and built the track. Then drilled the hole for at end (same size as the bulb (12mm). I then measured back 2.5” and put the dowel. The issue is that I had to sand down the dowel to 12mm because I couldn’t find one that size.
Theres no way there's actually a video about. I'm sure you've seen the barn metal showers. Imagine LED lights in the j-channel of a white barn metal shower
