The Nice Apollo gate opener models 1500, 1550ETL, 1600, and the 1650ETL can all be installed to open a swing gate up to 120° which will allow the gate to open wider and a little faster than in a normal installation. An alternate pivot position must be used to allow the gate operator to open up to 120°. All measurements are taken from the center of the hinge. If the pivot arm is to be attached to the hinge post it must be modified to accommodate gate actuator clearance.
Below is an illustration to demonstrate.
