MM272 Installation Instructions
Step 5
Be sure the position of the gate opener and brackets
allows for 1" of clearance between the gate and the
opener in both the open and closed position, while
at the same time maintaining a stroke distance of 7"
to 13" from center of hole in the end of the retracted
opener arm to the center of the hole in the gate bracket
with the gate in the closed position. This mounting
position will give the opener the most efficient
leverage point for operation and provides the least
possible pinch area.
Step 6
After verifying that you have the best position for
the post pivot bracket in the open position, insert the
5
/

" x 1
1
/
4
" 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. Again, check
the clearance and be sure that the gate opener is not
binding at the post pivot bracket.
If you don't have the required clearance, or if the gate
opener is binding on the post pivot bracket, remove the
5
/
16
" x 1
1
/
4
" bolt and readjust the post pivot bracket.
Reinstall the bolt and related hardware as shown in the
diagram to the right.
TIP: Turn the post pivot bracket over for more hole
alignment options. You can also move the entire post
bracket assembly to different positions on the post.
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.
Step 7
When the post bracket assembly is in the optimum position, reattach the opener to
the gate bracket (gate in the open position); recheck the gate opener level; make sure
the brackets are clamped securely.
Step 8
Mark reference points for bolt holes on the post through
middle of post bracket assembly slots. Mark reference points
for bolt holes on the gate cross member through middle
of gate bracket slots. After marking your reference points,
remove the opener and brackets from the fence and gate.
