Low Energy and Full Power Swing Door Operators

NABCO designed their Low Energy and Full Power Swing Door Operators to automate nearly any new or existing door. To create a custom operation, their adjustable closing speeds allow a door to close sooner for energy savings or slower for increased pedestrian safety. They ensure the industry’s longest-lasting products – and the highest level of customer satisfaction – by rigorously testing each operator for hundreds of cycles.
