This 20' single shaft silver aluminum Flagpole has revolving top, called a truck, which allows the Flag to turn round and round and round and never wrap.
The halyard runs internally up the Flagpole and then out to a counter-weight so you have no exposed rope when your Flag is at full staff.
Internal halyard Flagpoles also have locking access doors to prevent unauthorized lowering of your Flag.
If you want the best and most secure set up: then get an internal halyard Flagpole like this one.
You get your first MIL SPEC 2.33' x 4.5' U.S. Flag included in the price.
