When conduit is not used in new residential, low-voltage construction, cables can be pulled through the finished wall by using a _____.

• A. Mud ring
• B. Cable clip
• C. Stud finder
• D. Nail plate

Answer: (A)

When you’re not using conduit in new residential low‑voltage work, a smooth, protected path through the finished wall is essential for pulling cables. A mud ring around the box provides that path cleanly at the wall surface and creates a stable opening through which cables can be dragged from one side to the other without snagging on rough edges. It also keeps the box opening aligned with the drywall finish, helping the final installation look neat and meet spacing requirements.

Other items don’t facilitate pulling through the wall: a cable clip simply secures cable along a stud or surface; a stud finder helps locate framing but doesn’t create a passage for cables; a nail plate protects cables from nails after installation, but it isn’t a tool or feature used to pull cables through the wall.
