INSTALLERS TAKE NOTICE!
Overhead electrical lines, buried utility cables, and natural gas lines pose situations that require EXTREME CARE DURING INSTALLATION of foundation and flagpoles. 

Use concrete (3000 psi), unless otherwise specified.
1. Dig hole approximately as shown on chart. Dimensions are for "normal soil conditions."
2. Set sleeve slightly above finished grade level.
3. Set sleeve plumb in center of hole and begin to pour concrete around outside of sleeve. 4. During pouring of concrete, stop and check to be sure sleeve stays in center and level. 5. Cover sleeve opening to prevent accumulation of debris and water.

Foundation Dimensions - Dimensions shown are the minimum recommended for foundations "under normal soil conditions." This suggests; good, firm, dry soil. If you have questions, consult with an engineer in your area.
