Step 4
When you feel that you have the best position for the post pivot bracket in the open position, insert the 5/16" bolt through
the aligned holes of the post bracket and post pivot bracket to hold it in place. Remove the clevis pin from the front
mount and while supporting the gate opener, swing the gate and gate opener to the closed position. With the gate and
gate opener in the closed position check the clearance and be sure that the gate opener is not binding at the post pivot
bracket.
If you don't have 2 inches of clearance or the gate opener is binding on the post pivot bracket, remove the 5/16" bolt and
readjust the pivot bracket until you can achieve these important clearances. Reinstall the bolt and related hardware as
shown in Step 1.
With the post pivot bracket in the optimum position for clearance and freedom of movement while maintaining 19 inches
or less on the stroke. Reattach the opener to the gate bracket in the open position and recheck the gate opener level and
make sure the brackets are clamped securely.
If you are mounting to a post or column larger than 8" or you can not achieve the mentioned clearances, you can:
1) eliminate the post pivot to try and achieve the proper clearances.
2) install the unit as a push to open (bracket not included).
3) re-hang the gate within 4" inches of the back corner of the column.
NOTE: Re-hanging the gate, depending on the construction of a column, may require additional expertise and tools/
materials.
IMPORTANT: While determining the mounting point for the post pivot bracket assembly, be sure that the position allows
for minimum 2 inches of clearance between the gate and the opener in both the open and closed positions, as shown in
the diagrams below. This clearance will give the opener the most efficient leverage point for opening and closing the gate
and more importantly provides the least possible pinch area.
TIP: Turning the pivot bracket over
gives more hole alignment options for
the post pivot bracket assembly. You
can also move the entire post pivot
bracket assembly to different positions
on the gate post to help achieve the
proper clearances.
