What Are Utility Boxes?
Utility boxes, also known as service boxes or maintenance holes, are above-ground access points to underground public utility systems. They contain electrical circuits, telephone lines, cable TV feeds, fiber optic cables, and other telecommunication equipment.
Utility boxes allow workers to access, monitor, and repair the infrastructure inside without having to dig up the street. Their sturdy metal construction protects the sensitive equipment from weather, vandalism, and other damage.
Why Are Utility Boxes Painted Brown?
Most utility boxes you see are painted in a standard brown color. There are a few reasons for this:
- Blends in: The neutral brown color helps the utility boxes visually blend into the urban landscape rather than stand out. This helps maintain a consistent street aesthetic.
- Dirt masking: The dark brown shade hides dirt and grime buildup on the boxes to keep them looking cleaner.
- Rust prevention: The painted coating protects the metal housing from corrosion and rust.
- Graffiti deterrence: The dark color makes graffiti harder to see, deterring vandalism. Some boxes have special anti-graffiti coatings.
- Standardization: Brown is the standard color used by public works departments across many cities for uniformity.
