A Hose Reel is a cylindrical spindle made of metal and is used for storing a hose. The most common styles of hose reels are spring driven (which is self-retracting), hand crank, or motor driven. Hose reels are categorized by the diameter and length of the hose they hold, the pressure rating and the rewind method. Hose reels can either be fixed in a permanent location or portable or attached to a truck, trailer, or cart.
