This automatic single sliding drive-thru window is the perfect solution for hands-free service in the drive-thru food industry. It features a presence sensor photoelectric eye bar that detects presence and automatically opens/closes the window. This flush-mount, fully automatic, single slider glides smoothly on a top-hung slide rail system. The transaction window unit is either right or left handed, depending on your needs. An offset in the base prevents outside intrusion and repels water from entering into your establishment.
