Our inground external halyard flagpoles are great for commercial and residential use. They are made of tapered aluminum and are available from heights of 20' to 80'. The size and number of the flags that can be flown from your flagpole depends on the height. To select the right size flag(s) for your flagpole, see our Flag Size vs. Flagpole Height Chart. These flagpoles are wind-rated, making them designed to be safely flown in areas that have high winds. To determine the right flagpole for the winds in your area, see our Wind Chart. For all other questions, view our Flagpole FAQ page.
