Abstract: A flag holder designed to reduce the fraying of the trailing edge of a flag supports a flag with an upper fitting and a lower fitting. The upper fitting may be fixed with respect to the flagpole or, if desired, may rotate with respect to the flagpole. However, the upper fitting may not reciprocate with respect to the flag holder. The lower fitting may freely reciprocate with respect to the flagpole and, if desired, may be rotatable with respect to the flagpole. As soon as wind conditions exceed a desired threshold, the lower fitting begins to rise up the flagpole, moved by flexing of the flag, until it arrives at the location of the upper fitting, causing the body of the flag to assume an elongated generally U-shaped configuration which drastically reduces the snapping effect that would otherwise cause fraying of the downstream edge of the flag. As soon as wind conditions reduce, the lower fitting automatically lowers, causing the flag to be fully opened again.
