(*) The distances indicated in the table have been figured out on a gate having a thickness of 50 mm and a gate hinge
positioned at 50 mm from gate post. The above considerations can be applied even to gates having a different size,
leaving to the experience and technical skill of the installer the task of assessing the most suitable fixing geometry.

PRELIMINARY ASSESSMENTS BEFORE INSTALLATION
Since Aproli 280 Batt comes with an arm whose gate fixing end can be adjusted into three lengths (460, 520 and 580 mm), it is
required that the most suitable length be assessed in relation to the gate width (and inertia) and, also, in consideration of the
space that the arm is allowed to take in the most critical position when the gate is fully open (Pic. 5).

IMPORTANT: The longer is distance L from the gate hinge center, the greater is the lever action the arm can
exert onto the gate. This specially applies to heavy gates. But it is also to consider that D, ie. the space taken
by the arm when the gate is fully open, increases consequently. Both factors are to be assessed at first (arm
lever L and distance D with gate open) to find the most balanced solution to the application requirements.
