Step 2
Install a low profile ground stop (not provided) beneath the
SECOND gate stop plate.
The ground stop needs to be positioned near the end of the
gate as shown in Illustration A and may be made of metal
or concrete and should be firmly secured in the ground (we
recommend setting it in concrete).
Step 3
Attach a vertical closed position stop plate to the SECOND
gate.
Using appropriate hardware for your type of gate attach
the vertical closed position stop plate to the SECOND gate
frame at the point where it will come in contact with the
ground stop post.. Do not tighten it completely at this time. You must slide the closed position stop plate toward the ground
stop until they touch (Illustration C). Once you have moved the stop plate to the correct position, tighten its hardware
completely.
NOTE: For a push-to-open installation (gate opens out from the property) attach the closed position stop plate to the outside
of the gate.
At this stage of the installation, the openers should be installed on the
gate leaves and the open and closed position stops should be in place.
