The portable, stackable QuickWinder Cord Reels are designed to dispense, rewind, and store cord, cable, rope, and/or air hose. They are designed to load/unload easily; keep the cords clean; and prevent fraying, twisting, and tangling. Unreeling involves affixing the cord end then walking with (or carting) the reel to the object to be serviced; re-reeling involves cranking the handle with one hand while guiding the cord with the other. (The QuickWinder may also be mounted to a wall, roof, deck, truck bed, etc.) Numerous models are available to accommodate various cord lengths (50 to 4,000 feet) and diameters (1/4 to 5/8 inch). Some are wheeled and some include electrical cord.
