The Irwin STRAIT-LINE MACH6™ Chalk Reel features an Easy Fill and Lock Top that provides a wide opening for increased speed and visibility when filling the reel or accessing internals. The top locks securely with a ¼ turn to prevent unwanted spills. The 30m hi-tensile line is 2.5 times stronger than traditional chalk reels for fewer breaks on rough, abrasive surfaces, and the reel has a 6:1 gear ratio to rewind the line 6 times faster than traditional chalk reels.

Irwin STRAIT-LINE® marking chalks have an innovative flip-top cap that keeps the chalk in the bottle where you want it. The flip-top cap seals the chalk in an airtight chamber, keeping out moisture and reducing the risk of clumping.
