B1515 phase 2 gas line.png

This is an image of a measurement scale or ruler overlay. The image shows an orange/gold-colored vertical line with measurement indicators displaying "3 inch" at the top, "1 inch" in the middle horizontal section, and "3 inch" at the bottom. A horizontal line intersects the vertical line, creating a cross measurement reference. The background appears to be a blurred architectural or construction-related photograph, possibly showing a door frame, wall, or similar structure. The measurement overlay appears to be a calibration or reference tool for dimensional analysis, though the specific context or document type cannot be determined from the image alone.
