Installed on the ceilings, walls, floors, or other fixtures of plants, this device makes it possible to supply oil, air, and other materials to handy nearby units. A user can pull on the hose to extend it, let go to lock the hose in the extended position, and pull once more to cause the hose to roll up automatically. Its thin, large-diameter structure makes it possible to conserve plant space while still securing adequate length of hose. In addition to its simple steel-frame structure, suited to hard use, this design also gives consideration to safety, with gear components fully covered to prevent accidents such as workers getting caught in them.
