Diamond Dual Instruction Manual 7
We recommend you position the opener near the centerline of the gate to keep the gate from twisting and
flexing and to avoid backsplash from rain water.
The Post Bracket Assembly
The position of the post bracket assembly determines the leverage and efficiency of the opener. The post
bracket assembly position also sets the clearance between the opener and the gate in the open and closed
positions.
The post bracket works well for installations on round and square fence posts. Because the post bracket
carries the entire thrust of
the active opener, bolts must
completely penetrate the post.
On wood posts, place a metal
plate or washer (not supplied)
between the nuts and the post to
prevent the thrust of the opener
from pulling the bolts and washers
out of the wood.
The post pivot bracket may not be
necessary on posts larger than 6"
in diameter (see page 6). Fence
posts smaller than 6" in diameter
or 6" square should be made of
metal instead of wood to remain stable while the opener is moving the gate.

Reinforcing Gates for the Gate Brackets
We recommend using a muffler clamp, wood, or metal, to reinforce thin-walled tube gates, or wood to
reinforce panel gates as shown. These reinforcement methods will prevent damage to the opener and
gate. Additional hardware may be needed depending on the installation.
