troy6363 0 Posted March 27, 2011 Has anyone ever used this in wall viewer? Is it really necessary if I am drilling upward in the room where the dvr will be located. I am afraid of running into fire stops. Is it best to drill up from the room where dvr is located or is it best to drill down from the attic? Share this post Link to post Share on other sites
Soundy 1 Posted March 27, 2011 I'd go into the attic first and look at the structure and locations and directions of the rafters or joists... then drill from below, starting with a small bit to make test holes before drilling the big hole. If you're in a house, the only thing you should have to worry about running into is the joists or rafters (or wires or vents or something, but those should be easier to avoid). A stud finder is your friend. Share this post Link to post Share on other sites
troy6363 0 Posted March 27, 2011 How should I drill upward. I saw a pic of a guy who bought a 6ft flexible extension drill bit to drill up past any firestops and into the attic. Is this the way its normally done? Share this post Link to post Share on other sites
