Stanley Access Technologies of Farmington, Connecticut, has released the Series 500 Revolving Door, a manual revolving door that is cost-effective and energy efficient. The door also increases interior comfort by reducing infiltration of dust and dirt through the building entrance. The surface-mounted lower bearing and collapsing mechanism ensure many years of trouble-free service. The door features overhead speed control, standard deadbolt locks, concealed fasteners, and a book-fold wing position that is factory-set for emergency egress. The door comes in with clear or dark bronze anodized finishes, and special finishes are available on request. Other options included tinted glass, canopy lighting, and special heights.
