The Stanley 100-Foot FATMAX Chalk Line Reel features a water-resistant, high-impact ABS case with rubber grips, making it both extremely durable and easy to hold. The 3:1 gear ratio gives you a rewind that's 3 times faster, while the chalk line has twice the tensile strength of traditional lines and lasts twice as long. A convenient locking button holds the string in place. This reel holds one 4-ounce bottle of Stanley Chalk, and an easy-to-access screw cap simplifies the chalk refilling. The reel also features a long-wearing felt gasket that hugs the line and distributes chalk coating evenly. A stainless-steel universal hook withstands heavy use, and the crank handle folds neatly into case for storage and transit.
