Ethernet Hole Cover / Protector

Fits a single cat cable through the center.

I used a 1/2" drill bit and gently enlarged the hole by gently pressing the drill against the outside in a circular motion. A 17/32" would work much better than this, however I don't have one.

Give the face a rough sanding, depending on how aesthetically pleasing you want the piece to be.

Use a small amount of silicon around the outside of the ring to create a more permanent seal and properly mount the piece to the drywall.
