Two Doorhickeys -- One for the inside of the sliding glass door and one for the outside of the door! The original hands-free handle for sliding glass doors!  Remember to clean the glass with your BONUS microfiber cloth before installing!  Just twist the black suction cup by turning it counter-clockwise several revolutions, stick it on the CLEAN glass of your sliding door, and turn the handle clockwise until it becomes difficult to turn.  Then slide the door open and closed with your elbow, foot, hip, or...whatever!
