Gate Arm Mounting:
The position of Post Bracket is very important. The following illustrations and tables are required to determine the
proper mounting position for the Post Bracket, with the gate in the closed position. The table in Figure 5 shows the
maximum opening angle of the gate for a given A and B. For example, if A is 15cm and B is 20cm, the maximum
opening angle of the gate is 110°.
Figure 4 below shows simple pivot bracket positioning to achieve a minimum of 95° range of motion.
Note: Installing GTR058 on a Dual gate, steps 1-9 will apply to Gate Opener 1 (with 1.5m of cable), which should be
mounted on the control box side of the property. You will need to repeat these steps for Gate Owener 2 (with 6m of cable).
To find the maximum opening range of motion based on the set distances of
A
and
B
, refer to the table below:
A=8cm

Please Note:
Pay attention to distance
A when installing the
opener. It MUST be longer
than or at least equal to
8cm (3-1/4”), otherwise,
the actuator may not be
able to open the gate.
