Standard In-Roadway Warning Light 10″ Base Plate
LightGuard Systems® Inc. Part Number: LGS-SD10-C
Manufactured with high impact fiber reinforced thermoplastic polymer composite materials. The backward compatible 10″ base plate module features our “Debris Free Self Clearing™” design fluted face plate. The Base Plate is designed to accept the “LightStar™” signal head module.
The base plate dimensions are 10″ diameter by 1 1/2″ deep. The shallow depth ensures that the subsurface roadbed is not compromised.
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 IRWL 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 and helps 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. 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.
