STRAIT-LINE MACH 6 Chalk Reel Features:
The IRWIN STRAIT-LINE MACH6:tm: Chalk Reel features an Easy Fill & 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 90° turn to prevent unwanted spills. The 30m (100') hi-tensile line is 2.5X 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 6X faster than traditional chalk reels.
Used for general layout jobs, bricklaying, outdoor tiling, plumbing, setting plumb lines, and marking out on groundworks
