Preparation of the Gate Leaves
Step 1
The gate leaves must be plumb, level, and swing freely
on their 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 gate
leaves weighing 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 not twist or flex when the openers
are activated. Be sure to position the openers 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 Dual Gate (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 gate. Mounting the
openers on masonry columns requires special procedures; see Column Installation Information on page 37 if you intend to
mount the openers on columns. Furthermore, if you have a push-to-open dual gate, 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.
