3.13 Set the barrier arm in the
fully-open vertical position.
Have your helper use a level
tool to ensure the folding
part of the elbow is level
(horizontally) and stays level
during the next step.
3.14 Insert a pencil or sharpie through the eye of the threaded
rod end facing the offset plate.
While your partner keeps the
folding part of the elbow level
horizontally, carefully mark a line
going left and right onto the offset
plate. Keep the pencil
perpendicular to the arm and as
centered as possible within the
Threaded Rod End eye.
3.15 Drill a
⅜”
inch hole through the center of the marked cross
on the offset plate. Do not remove the offset plate or make
any more adjustments to the threaded rod as doing so may
cause the folding arm to not be level during operation.
NOTE: This hole should be made with high precision. We
recommend using a center punch tool about 2 times in the
center of the marked cross. Then create a
⅛”
pilot hole, a
second
¼”
hole, and a final
⅜”
hole.
