1. Call your local utility locating 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 (Q) will be
approximately 48” from the center of the footing for a BA777 Pole and 60” for a BA777XL Pole. 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 36” deep hole with a bell bottom will require approximately 4 cubic ft. or 3000 PSI
Quick Dry Concrete (T). 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.
