Highway call box for freeway made of matel. The weatherproof highway call box is rugged and durable. Special sealing design can ensure complete waterproof grade up to IP66. weatherproof , dustproof and moisture-resistant. The Highway call box widely used in expressway and outdoor. Most expressway project need install IP66 telephone for emergency communication. Solar powered highway emergency call box work as 911 call box for freeway assistance.
In the past, highway telephones were a useful communication tool that solved the problem of accidents that could not be rescued in the past on highways. Now with the construction of mobile communication devices, when people have an accident on the highway, they only need to dial 911 through their mobile phones, and this is a safer way. At present, in many places there are still places where mobile signals cannot be covered, and the construction of highway call box is indispensable.
