Keson Giant Chalk Line

Keson giant string chalk lines create bold, highly visible marks ideal for parking lots, streets, and concrete surfaces. Models G100 and G110 hold over one pound of chalk and offer 100 or 110 feet of giant string with a durable one-piece steel crank and a convenient pull ring. The G130 and G150 extend these features with up to 150 feet of string for longer projects. For enhanced comfort and efficiency, the G3X and G3X100 include an ergonomic grip designed to reduce wrist strain, a 12-ounce chalk capacity, and a 3X rewind system for fast line payout and retrieval. The G3X100 also features a chalk catcher to minimize waste and keep clothes clean.
