Cabling Devices

J-Hooks

J-hooks are cable management devices similar in form and function to D-rings.

Whereas a D-ring, once mounted on a wall, support, or other solid surface, is a

closed hoop through which cable is threaded, J-hooks are open, and simply act as

a support for the cable. J-hooks are often used to provide strain relief at strategic

points in a run of cable or bundle of cables, or may be used in locations where

cables must be added or removed from easily-accessible areas often. An example

of this latter type of installation might be a testing laboratory which provides lines

of J-hooks along the walls for the routing of temporary cables.

Strain-Relief Bracket

The strain-relief bracket is a cable management device that is often used when

networking hardware is mounted in an equipment cabinet or electrical

equipment rack. The strain-relief bracket is a wide, U-shaped metal bar tthat

extends forward from a device which cables plug into.

Figure 13-10. Strain Relief Bracket

The strain-relief bracket provides a location where cables may be tied off. This

alleviates the strain of the weight of the cable, removing it from the port or

connector and transferring it to the strain-relief bracket. Cables may be fastened to

strain-relief brackets with wire twist ties, string, or Ty-Wraps.
