IRWIN Chalk line reel, ratio 6:1 type 7327

Design: Durable housing made of aluminium with robust, durable nylon/polyester cord with large hook, transmission ratio 6:1. The cord pulley has a chalk shredder, that shreds the chalk before input to prevent failure as a result of coil tilting. The releasable drive prevents the metal crank handle from turning when pulling out the cord. Refill cap for quick and easy refilling, it also serves as a secure lock.
