It is important to check the length of your upright on your glider and make sure that you purchase the correct length of upright.   These uprights are too short for most Avian hang gliders.  They fit a smaller A frame suitable for smaller pilots.

Please note the condition of your double button spring pins.  These sometimes fail and a spare is a good idea.

Sometimes with sideways failure of an upright is possible to damage the other upright or upright casting at the same time.  Check the castings for damage they sometimes crack! and should of course be replaced.
