Preparation of the Gate
Step 1
The gate must be plumb, level, and swing freely on its
hinges. Wheels must not be attached to the gate. The
gate must move throughout its arc without binding or
dragging on the ground. Note that gates over 250 lb.
should have ball bearing hinges with grease fittings.
Step 2
The fence post must be secured in the ground with
concrete so it will minimize twist or flex when the
opener is activated. We recommend you position the
opener near the centerline of the gate to keep the gate
from twisting and flexing. The addition of a horizontal
or vertical cross member (if one is not already in place)
to provide a stable area for mounting the gate bracket is
also important.
Installation Overview
Pull-to-Open Gates (Gate Opens into the Property)
The diagram shown below is an example of a pull-to-open installation on a chain link fence and single gate. Mounting the
opener on a masonry column requires special procedures; see Column Installation Information on page 36 if you intend
to mount the opener on a column. Furthermore, if you have a push-to-open gate, you will need to purchase a push-to-open
bracket (see Accessory Catalog) to properly configure your system. See Push to Open Installation on page 30 before
proceeding.
