Installation of Mounting Hardware
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. 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.
