IMPROPER INSTALLATION, MAINTENANCE OR USE MAY CAUSE FAILURE AND SERIOUS PERSONAL
1. Call your local utility locator service, usually by dialing 811, before digging to avoid serious injury or
service interruption.
2. Select the location for the concrete base footing. Note that the face of the Backboard (P) will be distanced
from the center of the footing according to information in Figure 12. Dig a 12" diameter hole that is 48"
deep, remove additional soil from the bottom 1/3 - 1/2 of the hole in a bell shape to add pole stability. In
areas where the normal frost line is below 48" it is advisable to dig to the normal frost line. See Figure 1.
3. Make sure that you have a level and a broomstick or similar pole to vibrate air pockets out of concrete. A
12" diameter by 48" deep hole with a bell bottom will require approximately 5 cubic ft. of
Quick Dry Concrete (S). You will need to adjust the amount depending on the size of hole you prepared.
Having too much is better than having too little.
4. Mix concrete according to the directions on the bag. It is advantageous to have the mixture "wet". This
will increase your working time and allow batches to mix in the hole. Pour the hole full to ground level.
