STEP 2
Install chain brackets at each end of the gate on the inside
(operator side) of the gate (see Overview Illustration, page.
12). Position the tops of chain brackets no more than 6” above
the bottom corners of the gate frame and secure with U-bolts
(see Illustration B). The chain brackets will work on gate

DETERMINING THE MOUNTING POSITION AND MOUNTING THE OPERATOR
STEP 4
Find the center point between the two roller/fence posts (see
Illustration D). This should coincide with the position of the
center point of the operator. Dig a hole approximately 12” x 28”
wide x 28” deep. Place the operator in the hole on its legs and
position the bottom idler sprockets on the top of the string and
level the unit (see Illustration E). Make sure operator is level and
plumb. With the unit level and in place, pour the concrete and let
set for 24 hours (checking the level periodically) before
proceeding to the next step.
BEFORE POURING CONCRETE: 1] Make sure operator is
centered between roller posts and aligned with string; and,
2]
Determine method of installing conduit for wiring (see page
13)!
STEP 3
Insert a quick release pin into the center slot in each of the chain
brackets (see Illustration C). Tie a string to the end of each quick
release pin so that the string is tight between the two chain brackets (the
string will be used to align the operator). The string should be 7”-10”
from the ground (see Illustration B). The chain brackets can be adjusted
up or down on the gate to achieve the proper height. The goal here is
to set the height of the operator so that when the housing is in place it
will clear the ground by 1” to 4” (see Illustration E).
