Product Details

Phone Symbol Sign - D9-1

Engineered for clear communication in rural and highway environments, this Phone Symbol Sign delivers essential wayfinding information for travelers. Constructed with high-quality reflective aluminum and precision radius corners, the sign meets stringent Department of Transportation (DOT) and Manual on Uniform Traffic Control Devices (MUTCD) state and federal guidelines. Designed with 3/8" prepunched holes and available in high-intensity and diamond-grade reflective sheeting, this D9-1 sign provides critical guidance for roadway users. When telephone services are located in unexpected areas or at rural interchanges with multiple service options, this sign can be independently mounted to direct travelers to available communication facilities.
