I’m running some networking cable from my attic to my basement (only going through one main level). The best place to run the cabling takes me through an old covered up door (closet) frame on the way down. It was closed off when the house was renovated before we bought it.
I have the holes drilled up from the basement and down from the attic, but about 10-12” down, there is what I assume to be an old header. I have verified that they did not add additional framing in the former doorway with a stud finder. There is no electrical, water, or HVAC in that wall.
This metal mesh/material is getting in my way. Can anyone add advice? This is looking with an endoscope straight down from the attic.
