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

• A. Mud ring
• B. Wall plate
• C. Grommet
• D. Cable sleeve

Answer: (A)

The key idea is to have a protected, properly sized opening through the wall for the conductors when you’re not using conduit. A mud ring is installed around the low‑voltage box to extend and align it with the finished wall, creating a clean, recessed opening that cables can be pulled through into the box without snagging on rough edges. This helps the wall finish sit correctly and makes later terminations or faceplate installation straightforward. The other items don’t serve the same purpose in this scenario: a wall plate is just the exterior cover after finishing; a grommet protects a single hole’s edge but doesn’t provide a built‑in path through the wall for multiple conductors; a cable sleeve acts like a protective conduit route, which isn’t the intent when the design specifies no conduit.
