Note uses 6mm plastic clips with screw hold in center (order extra)... because of the width, tricky to screw into driveway wood, I used much longer #6 screws, with a long skinny screwdriver... hold the rope light nice & tight. This one worked great for me, but thicking on the next one increases the the rope thickness (8mm up to 12mm).
Hope this helps !
Love the flexibility & brightness...
ALSO - You have to add a POWER ADAPTER to this rope light.
