Column Installation Information
READ THE FOLLOWING CAREFULLY BEFORE INSTALLING THE GTO/PRO 1000 AND
GTO/PRO 1200 ON GATES THAT ARE MOUNTED ON COLUMNS MADE OF MASONRY,
BRICK, ROCK, etc.
Attaching a gate operator to a gate mounted on a masonry column requires special procedures.
Here's how to check your installation to minimize problems:
Open the gate to the 90º position, then measure the distance between the back of the gate and
the face of the column. If there is at least a 6

special modifications. However, you must measure the post pivot bracket position using 4

" setback, as described on page 13 of this manual, to verify that the gate hinge sits far
enough from the column to give your installation the proper setback distance.
If you do not have the proper clearance or setback distance, the operator may operate the gate for a while, but
eventually the unit will become nonfunctional. To prevent this problem, we suggest the following installation
method:
A.
The simplest solution is to install the operator in a push-to-open configuration (push-to-open bracket(s)
are required; see accessories on page 43). The crucial 4

" setback is actually easier to achieve this way
and clearance is no longer a problem, since the operator will be pushing the gate away from the column
instead of pulling it toward the column. It is recommended that you place a steel plate between the operator
mounting brackets and masonry surface for additional strength.
B.
If a push-to-open option is impossible due to traffic hazards, terrain, etc., another option is to re-hang the
gate. You might hang it on a post, either in the center of the column or at the back corner, or move the
gate to the back corner of the columns.
C.
The most difficult solution is to notch a pocket in the column to accommodate the operator and power
cable. This is not a job for the inexperienced!
