Where is an escutcheon ring used?

• A. Inside wall
• B. Outside of the stub out pipe
• C. On drain
• D. On vent

Answer: (B)

An escutcheon ring is a finishing cover that goes around a pipe as it passes through a surface, like a wall, to hide the hole and provide a neat, protected edge. It sits on the outside of the stub-out pipe where the pipe enters the wall, not inside the wall. This placement hides rough edges and insulation and helps prevent damage to the pipe at the penetration. It isn’t used on drains or vents, and placing it inside the wall wouldn’t serve its purpose of providing a visible, protective cover around the pipe.
