Overhead Door Corporation's non-rated counter doors are ideal for such applications as concession areas, cafeterias, pharmacies, parts-storage areas and ticket windows. Curtains consist of interlocking, flat-profile aluminum, steel or stainless steel slats. Manual push-up operation is standard, with optional crank or motor drive. Slide bolt locks are provided, with cylinder locks optional. All counter doors except integral-frame doors can be mounted to the face of the wall or between jambs.
