ABSTRACT:
A guardrail block includes an attachable support for signage, such as a reflector. The reflector may be mountable on the support, and the support may be integrated with a base or may be separate and attached to the base. For example, a support may be snap fit into the base and the base can be slip fitted into recessed channels formed in elongated extensions extending from a top surface of the guardrail block. The guardrail block may be made of a synthetic foam material, the support and base may be die injection molded, and the reflector may be reflective tape adhered to a surface of the support, for example.
