- UV-stabilized color protection to resist fading over time
- High-impact resistance for durability in demanding environments

Durable and Visible Marker Post
Positioned just below the CP Test Station, the Marker Post features a printed sleeve crafted from specially formulated HDPE, enhanced with unique pigments and UV inhibitors for long-lasting color and clarity. The sleeve allows for multi-color decoration, providing visibility and ensuring easy identification of the marker’s function.
Constructed from high-quality HDPE, the marker post is available in standard lengths of 6’ and 8’, with custom lengths available to suit specific needs. This durable design ensures stability, visibility, and weather resistance, making it an ideal choice for both line marking and testing.


Clear Identification for Dual Functionality
