Here's the drum on cable protection
Here's an improvement on the use of a piece of split storm water pipe to protect cables as you drag them through masonry walls.
Garry and Cokes from B&K Lewis Electrical have found that if you cut a quarter out of a small plastic cable drum and jam this over the wall, it protects the cable both from the bottom of the hole and catching on the side. No more damaged insulation. Thanks guys, and congratulations. You have just picked up a cheque for $250 from The Olex Cable Guy.
