Problem
After running Category 5 cable above a ceiling, dropping it vertically can strain and bind the cable, damaging it and causing signal degradation.
Solution
Create a ladder using conduit supports, beam clamps, and 2-inch polyvinyl chloride (pvc) or metallic conduit. A ladder of this type will support the cable and minimize strain at the drop point, as well as limit damage to the cable.
Srocedure
1) Run the cable horizontally to the wall or beam, using wide-base J-hook cable supports.
2) At the drop point, attach a piece of 2-inch conduit to the wall or beam with a "hammer-on" support and a beam clamp.
3) Loosely wrap the cable around the conduit a full 360o.
4) Drop the remaining cable vertically to the next wrap point.
5) Continue this looping process every 4 to 6 feet, or as needed, on the vertical run.
