Review: Perfect for the need! - Great product, exactly what I need.
Review: Nice color, don't last long out in the elements - Great color, easy installation. The coating yellows quickly. I'm not sure if it's from the heat of the lights or the elements. Two of my four sets have failed in under 2 years. They are not expensive so I'll just spend the couple of pennies to replace them. As I started with, I like the color.

### ⭐⭐⭐⭐⭐ Perfect for the need!

### ⭐⭐⭐ Nice color, don't last long out in the elements

### ⭐⭐⭐⭐⭐ They get the job done
*by R***. on May 16, 2022*

They’re flat, they have multiple pre-drilled fastener widths as you can see in the pic. Also, a blank area to drill your own holes. One masssssssssssive word of caution. If you’re either opening up the pre-drilled holes larger with a drill bit or making your own. Go very slow, especially closer to the edge. Very low grade material that is crumbly (which isn’t an issue for this purpose), it’ll blow out. So slowly increase the bit size from if you’re going larger than 1/8”
