I have a swinging garage gate that is hitting my driveway when open, how to mitigate?
If you angle the gate pivot slightly such that the line passing through the pivots is tilted slightly forward at the top, the gate will rise as it opens.  If you accomplish this offset on the gate side rather then the post side, the gate can still be vertical when closed, but that might take a bit of fabrication. For a small rise, it probably won't be very noticeable, but that depends on the length &amp; height of the gate.
