Specialty Blank Switch Plate for Midcentury Round Phone Jack Box

Designed for covering round telephone boxes found in midcentury homes. Circular boxes are 2-1/4" in diameter and typically had a raised circular phone jack and domed plate that was 3.25" in diameter. Use this plate when removing the phone jack insert and closing off the box. This custom wallplate's 3.5" width will hide any paint build-up around the circular bracket and plate plus any unfinished areas that were hidden under it.
