Determine Proper Brackets and Opening Method
Mounting Brackets
Determining which of the brackets will be needed for your installation.
The Sentry gate opener is supplied with universal brackets to mount on round
or square hinge post ranging in size from 2 3/8” to 6”. Some pieces may not be
needed for your installation.
The hinge post is the post your gate hinges are attached to. Follow the
steps below to identify which of the included brackets will be needed for your
installation.
Is the hinge post round or square?
Square post will use the “square post flush mount bracket”
Round post will use the “round post flush mount bracket”
NOTE:
If a round post is to be used it might be necessary to brace the post so
that it does not rotate. A round post simply installed in concrete will rotate, if
possible drill holes through the post and insert rebar through the post prior to
concrete to prevent rotation.
Is the gate a light weight farm gate?
If so, use the “gate support brackets” to attach the gate bracket so that the
bolts can be securely tightened.
Universal Actuator Bracket
The universal actuator bracket can be installed in many different ways to
accommodate your gate opener installation. Use the images below to help
understand the mounting options for this bracket and determine the installation
method you are going to use. The images are for reference only and your installation might differ.
Universal actuator bracket must be securely installed. Drilling through the post is the strongest
method. It is also recommended that the square post flush mount bracket or the round post flush
mount bracket be installed for strength on opposite side of post from the universal bracket (see
figures below).
When determining where the universal actuator bracket will mount on the hinge post you must also
consider where the gate bracket is going to connect to the gate. The gate bracket is going to attach
approximately 34” out on the gate measured from the gate hinge center.
Once universal actuator bracket location is determined, verify that the gate bracket can be installed to
the gate so that linear actuator is level.
