Installation of Mounting Hardware
POST BRACKET
The position of the post bracket determines the leverage and efciency of the
opener. The post bracket position also sets the 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 through the wood.
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.
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. See examples below.

GATE BRACKET
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.
