Preparation of the Gate
Step 1
The gates
must
be plumb, level, and swing freely on
their hinges. Wheels must not be attached to the gates.
The gates must move throughout their 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 posts must be secured in the ground with
concrete so they will minimize twist or flex when the
openers are activated. We recommend you position the
openers near the
centerline
of the gates to keep the gates
from twisting and flexing and to avoid backsplash from
rainwater. The addition of
horizontal or vertical cross
members
(if they are not already in place) to provide
a stable area for mounting the gate brackets 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 dual gates. Mounting the
openers on a masonry column requires special procedures;
see
Column Installation Information
on page 38
if you intend
to mount the openers on columns. Furthermore, if you have push-to-open gates, you will need to purchase two (2)
push-
to-open brackets
(see
Accessory Catalog
) to properly configure your system. See
Push to Open Installation
on page 32
before proceeding.
