Attach Opener Arm
Step 1
Attach the opener 
to the securely 
bolted post bracket 
assembly and gate 
bracket using clevis 
pins, bushings, 
and hairpin clips, or 
optional Pin Lock 
[FM133] (page 
26). Verify that the 
opener is level and 
adjust the post 
bracket assembly, if 
necessary.
Step 2
Install the SECOND gate opener and hardware on the second gate following the same procedures as the FIRST gate 
opener and hardware ("Installing Post Bracket Assembly and Gate Bracket" Steps 1–10). 
NOTE: The power cable for the Second Opener should be run in PVC conduit under the driveway to protect it from 
damage due to lawnmowers, heavy equipment, etc. (See illustration on page 6.) NEVER SPLICE opener arm power 
cables. This will cause performance problems and may damage the opener.
