Which device is used to allow pulling cables through finished walls when conduit is not used?

• A. Grommet
• B. Wall plate
• C. Mud ring
• D. Conduit

Answer: (C)

When you need to pull cables through finished walls without using conduit, the important thing is to create a smooth, protected path for the cable. A grommet is placed in the wall hole to shield the cable from sharp edges and to reduce friction during the pull, which makes pulling safer and easier and helps prevent damage to the cable. Mud rings, on the other hand, are used to bring a box flush with the wall after drywall is finished; they don’t provide a guiding or protective passage for cable through the wall. Wall plates cover the box opening, and conduit is a protective pathway used when you are running cables through a raceway. So the device that best fits this scenario is the grommet.
