Cable Holders

This photo shows the full cable run to the attic, in the short space in the basement where they run under the floor joists from the panel to where they turn and run up the inside of the foyer wall. I found these red plastic cable holders, knowing they would come in handy wiring the attic, and for other locations, such as between two main air ducts here, where I didn't have enough room to drill holes through the joists to accommodate the cable. Each holder can carry four 2-wire and two 3-wire cables.
