1/18 Scale RC K-Rail / Jersey Barrier System

This 1/18 scale K-Rail (Jersey barrier) is designed to add realistic roadway control, course boundaries, and visual structure to RC rock crawler courses and scale construction scenes. Inspired by real-world concrete K-Rails, it’s scaled specifically for 1/18 crawlers to look correct while remaining easy to place and reposition during course setup.

Each barrier section is a freestanding piece with a low-profile base that sits naturally on dirt, gravel, and rock terrain. Sections are intentionally not physically connected, allowing you to freely space, angle, and offset them to create natural-looking boundaries, chicanes, and technical crawl lines without being locked into a fixed layout.

This makes the K-Rails ideal for dynamic course building, photo setups, and backyard trails where flexibility matters.
