Precision marking is essential for layout accuracy, and this giant chalk reel is engineered to provide consistent, sharp, and easy-to-see lines across large surface areas, helping crews save time and reduce errors on the jobsite.

Made in the USA, the G3X100 combines durable construction with ergonomic design to ensure long-lasting performance and comfort during extended use. Its professional-grade components make it ideal for contractors who rely on dependable, high-quality tools for daily asphalt and concrete marking tasks.

Ergonomic and User-Friendly Design

The Keson G3X100 features an ergonomic handle designed to reduce wrist strain, allowing operators to maintain control and comfort during long marking sessions. The “glovable” grip ensures a secure hold even in cold or wet weather, improving usability in a variety of conditions. Its lightweight yet robust construction makes it easy to maneuver across expansive parking lots or tight jobsite areas, without compromising durability.

The giant line reel is equipped with a Huge Big Mouth™ opening, which simplifies chalk refills while minimizing mess. A no-leak stopper keeps chalk securely inside, preventing waste and accidental spills on clothing or fresh sealcoat. In addition, the chalk catcher feature further reduces waste, ensuring more efficient chalk usage and keeping lines precise and clean.

Fast and Efficient Line Marking

With its 3X rewind mechanism, the G3X100 allows fast line payout and retrieval, significantly speeding up layout and marking operations. Contractors can quickly cover large areas, maintain a smooth workflow, and reduce downtime caused by manual rewinding. The reel holds up to 12 ounces of chalk, providing extended operation without frequent refills, making it perfect for commercial lots, roadways, and multi-lane projects.

This chalk reel is also compatible with a wide variety of marking chalks, allowing professionals to choose the color and type that best suits the project and visibility requirements. Its precise, even chalk distribution ensures consistent, straight lines every time, supporting accuracy and efficiency in all asphalt and concrete marking applications.
