I am putting up short sections of aluminum fencing inside my patio in the back and up one side, to deter people & pets from jumping off the patio at those points. A gazebo is going to be permanently set up on this patio, inside the fence sections.
I am going to set the aluminum fence posts into concrete. The posts provided are 56" tall, the fence panels are 45". I live in Maine, so I need to put forms in and set them below the frost line (4') yet it states in the installation directions that "The posts themselves do NOT have to go below the frost line, however, for proper installation."
My question is, how do I keep the fence post at the proper height and plumb, if it is not going to have the stability of reaching the bottom of the hole?
