My exterior walls are brick. inside it's dry wall. My house was built in 1950. I'm not sure what's between the drywall and brick but I'd like to fish a cable down from the attic to this wall where my TV is located.
I'd like to drill a hole through the attic down into the wall cavity and then down to a hole I will make in the drywall.
My concerns are, will there (should there) be any horizontal studs along this cavity? And what would you assume is behind the drywall (on an external wall made of brick) on a house built in 1949?
I've done this with interior walls before, but I don't know whats on the other side of an external facing wall.
Stud finder seemed to only have vertical slats
