The Swing IQ units have Smart Power Boost technology.
Smart Power Boost
The Swing IQ with Power Boost set to max, the closing force, near the door-closed position, is about 18 lbs total (spring plus boost). Keep in mind that power boost force changes based on a lot of factors (arm type, door angle, door size, door weight, etc.). Also, on the Swing IQ, Power Boost force is adjustable from a 1 to 10 because of the wide range of applications, door weights, door widths, arm type, air pressures, other elements etc….
