Good product
The hole covers are great. As far as the hole cutting bit. Not so much. But still worth the price.

Hides the cables
Size: 36", Size: 36"
Hides the cables. A little expensive but works well. When drilling the holes, be sure to be mindful of the overhang of the net compared to the brackets and the paper template.
