Adjust and Mount Gate Arm Bracket

What happens here

The gate opener arm itself is adjustable. Loosen the set screw to manually extend or retract the inner arm. Full extension of the arm corresponds to the gate being in the closed position, while retraction opens the gate. Set the arm to its fully extended position and snug the set screw. Next, attach the U-bolt style bracket to one of the horizontal bars of the gate. This bracket will connect to the extended arm. Loosely tighten the nuts on the U-bolt bracket to allow for minor adjustments. Use an impact driver and a wrench to fully tighten all nuts and bolts once the final position is confirmed.

Goal: Securely attach the gate arm and adjust its length for proper function
