The Brooks Products model #1-RT is a traffic rated valve box with cast iron cover that is used as a "flush" or grade installed cathodic protection test station. Since it's made of concrete and cast iron, the #1-RT is very durable. It is recommended that an actual test station be used inside the #1-RT as this will help protect cable terminations below grade as water egress can be an issue.
The #1-RT can be purchase as a set or in pieces that include:
- Valve box body
- Cast iron lid
- Cast iron riser rings (to raise when asphalt is added to a street)
- Concrete extensions
