10″ Standard Composite IRWL Base Plate
Base plates protect and house the 9X LED LightStar in-roadway warning light signal head—and are designed for durability and reliability in the roadway. Our 10” x 1.5” standard base plate is made of ultra-high strength, high impact fiber reinforced thermoplastic polymer composite material. It is designed to be permanently embedded into the roadway for years of maintenance free operation.
Features & Benefits:
- Secures to roadway
- Easily installs into pavement
- Maintenance free operation
- Simple electrical connections
- Debris Free™ Self Clearing design
- Adaptable to tamper resistant hardware
- High strength impact resistant composite
- Dimensions: 10″ diameter by 1 1/2″ deep
Our Debris Free™ Self Clearing design features fluted air channels. As tires pass over the base plate, the compressed air channels dirt and debris through the fluted air channels — keeping the LED signal head free from roadway debris build up.
The slight elevation of the IRWL signal head positioned above the road grade is intended to alleviate blockage by debris. Its shallow 1 1/2″ depth ensures that the subsurface roadbed is not compromised. The base plate is compatible with our 9X LED LightStar™ signal head module.
Two part epoxy compound is used to permanently to embed the base plate into the roadway. The base plate can be installed into asphalt or concrete.
The in-roadway warning light system cable conductors are also embedded into the road via direct burial or in conduit. The base plate interior cavity is designed to contain all the electrical wiring for a signal head module. An elastomer O ring is placed between the signal head and the base plate to create a seal.
During manufacturing, four rust proof brass threaded screw receptacles are inserted into the bottom side of the base plate. This feature prevents the mounting screws from being pulled out of the base plate and reduces metal rusting. The signal head is fastened to the base plate with stainless steel socket head 1/4″-20 screws with thread lock and anti-seize compound is applied to the brass threads in the factory.
