Overhead retractable hoses are rather convenient in many situations. above Figure shows a retractable hose reel that may be hung from the ceiling or the wall. These reels are very useful and can be seen in almost every auto repair shop in the nation. below Figure shows a coil hose. These hoses are perfect for assembly benches or applications that require only limited movement of the air tool. It should be noted that these hoses are a tangling nightmare if they are used while laying on a flat surface. Another attribute of retractable hoses is that they are extremely easy to put away.
