Crescent chalk reels are feature-rich in order to make every pro’s work easier, and the 150’ Construction Reel is built to handle the toughest jobs. The sit-flat case design makes refilling fast and clean with its one-way quick refill valve or slide-door opening. An easily accessible hub lock keeps the reel firmly anchored and the end hook/ring combo clips securely into a docking channel, preventing snags when stored. Thicker, compound braided line produces highly visible lines, snap after snap and the 6:1 gear ratio makes retraction surprisingly fast.
