If you notice strain when opening/closing, consider mounting the actuator so that:
the arm operates parallel to the floor, or;
the arm opens up toward the ceiling.
GRIT Gate Control devices, when powered properly, operate in any orientation. Some
placement considerations can be made, however, to assist in their best performance.
GATE CONTROL
Orientation
If the location of the existing blast gate does not allow for mounting the gate
actuator as shown above, you can move the actuator to the other side of the blast
gate by changing the direction of the Slide Bracket post.
The Slide Bracket arrives assembled
with an M3 x 30mm post, M4 lock
washer, M4 nut, hat and flat washers,
a M4 Lock nut, finally, an M3 x 8mm
screw to secure the bracket to the
gate's tab.
