Flagpole Flag kit
Flag antiwrap concept. It is a flagpole with ball bearing. This picture shows it with a 3x5' flag, but you can buy the
"no wrap flagpole hardware" set without a flag.
This rotating flagpole has a ring of ball bearings that separates the
top half of the pole from the bottom half. Your flag is free to rotate as the top half of the pole spins independently from the bottom half.
Not all flagpole hardware is equal. An unwrapping flagpole is much handier.
