clearance between the opener and gate in the open and closed positions (minimum 2 inches).
The curved design of 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 that completely penetrate the fence post must be used.
On wooden posts, place a metal plate or washer
(not supplied) between the nuts and the fence
post to prevent the thrust of the opener from
pulling the bolts and washers out of the wood.
NOTE: A fence post smaller than 6" in diameter
or 6" square should be made of metal instead
of wood so that it will remain stable while the
opener is moving the gate.
On round posts of 6" diameter or larger, the post pivot bracket may
not be necessary for the installation. In this instance, the two post
brackets are mounted by themselves.

Recommended Reinforcement Examples
IMPORTANT:
We strongly recommend using steel pipe, 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 when the opener is installed.
