I want to move my router from my office to the hall, directly through the drywall on both sides, and then run the router power cable (low-voltage because it is post-transformer) and two Cat6 cables (one to cable modem and one to switch) straight through the pair of holes. I'd like some sort of plug or bushing (PVC?) to be put into the holes in the drywall so it doesn't just look like a hole in the drywall. It would need to be 3/4" outside diameter. Any ideas?
Happy holidays, Lud Nom
