High-Visibility Delineation for Guardrail Systems

The Guardrail Post-Mounted Delineator provides transportation agencies and roadway contractors with a durable, highly visible solution for marking guardrail along highways, curves, ramps, bridges and other roadside locations.

Designed for direct installation on guardrail posts, the delineator improves nighttime and low-visibility guidance without requiring a separate roadside post. Its reflective surface helps drivers recognize roadway alignment, changing conditions and fixed roadside barriers from a greater distance.

Available through RoadSafe, Guardrail Post-Mounted Delineators are well suited for new guardrail installations, roadway improvement projects and replacement of damaged or missing delineators.

A Practical Solution for DOT and Contractor Projects

Guardrail delineation must remain visible while standing up to weather, traffic exposure and routine roadside maintenance. The post-mounted design uses the existing guardrail system for support, helping reduce installation time and the need for additional foundations or ground-mounted hardware.

These delineators can be installed as part of a new guardrail project or added to an existing system to improve roadway guidance and visibility.

RoadSafe can help state and local transportation agencies, highway contractors, guardrail installers and maintenance crews select the appropriate delineator configuration and reflective color for project specifications.

Common Applications

Guardrail Post-Mounted Delineators can be used for:

• Interstate and highway guardrail
• Curves and changes in roadway alignment
• Entrance and exit ramps
• Bridge approaches
• Median guardrail systems
• Rural and low-light roadways
• Work zone and temporary traffic patterns
• Guardrail repair and maintenance projects
• State, county and municipal roadway improvements

Features and Benefits

• Mounts directly to guardrail posts
• Improves nighttime and low-visibility guidance
• Helps identify roadway alignment and roadside barriers
• Uses existing guardrail posts for support
• Reduces the need for separate delineator posts
• Suitable for new construction and retrofit applications
• Lightweight and easy to handle in the field
• Designed for efficient installation and replacement
• Available with reflective configurations for project requirements
• Suitable for permanent and temporary roadway applications

Built for Efficient Installation and Maintenance

The post-mounted configuration allows contractors and maintenance crews to install delineators while completing guardrail work, reducing the need for a separate installation process.

Damaged or missing units can be replaced individually without removing the guardrail post. This helps simplify ongoing maintenance and allows agencies to restore delineation quickly following roadway incidents, snowplow damage or normal wear.
