Klein Tools CHLK100S Chalk Reel - 100 ft, 6:1 Gear, Quick-Release Spool

Meet the Klein Tools CHLK100S Chalk Reel, a professional-grade chalk line tool built for reliability and precise layout work. With a robust 6:1 gear ratio, it significantly reduces downtime between marking tasks, helping crews move from layout to layout with confidence. The chalk level window lets you monitor supply at a glance without opening the tool, while the twist-lock top keeps chalk contained and spill-free during transport. The quick-release spool clutch enables fast line extension, and the nested hook design keeps the hook flush against the reel to prevent tangling during transit. Since 1857, Klein Tools has combined engineering expertise with durable materials to deliver tools that stand up to demanding professional use.

Designed for comfort and control, this chalk reel pairs an overmolded, non-slip grip with thoughtful details that reduce interference during busy days on the job site. A removable belt clip adds flexible carrying options, so you can keep the tool close at hand whether you’re climbing, kneeling, or working in tight quarters. The CHLK100S ships with a 4-ounce blue chalk refill, ensuring you can begin marking right away and maintain visibility on each mark.
