  • Proven design for proven reliability
  • Works with new or existing door frames
  • Mechanical operator used with basic electronic or microprocessor (standard) controler provides smooth, efficient operation
  • Adjustable closing speeds allow the door to close sooner for energy savings or slower for increased pedestrian protection
  • Mechanical operator used with microprocessor provides efficient, smooth operation
  • Works with butt-hung, offset pivot or center pivot door without requiring the special linkage making it easy to install
