Irwin’s Strait-line Mach 6 Chalk Reel (pictured) features an Easy Fill & Lock Top that provides a wide opening for increased speed and visibility. The top is constructed of the same impact-resistant aluminum as the body and can be locked securely with a quarter turn. The 100’ high-tensile line is 2.5-times stronger and the reel has a 6:1 gear ratio. It features an open-access back panel for quick line change and cleaning, wide-prong hook, steel handle, large clutch and metal drive gear.
