Hi, I have 4 audio cables entering the wall of my house through a hole that is missing its wallplate/faceplate. These cables go to speakers around the house. Because of this, during winter, cold air comes through this hole. Is there some kind of faceplate that can allow cables to go through it, but yet forms some kind of seal to keep out cold air? There is a J-box in this hole. So I should be able to just screw on an approp wallplate/faceplate.
The size of the hole is the same size as that for a normal 2 socket power receptacle.
Thanks
