J-clip for canopy cover
This J-clip is designed for fitting to the end of a bungee used to hold a canopy cover on a glider wing. It's 50mm wide, so the load is spread over a larger area than some of the hooks that I have seen. J-section goes over the trailing edge of the wing, and the hole allows a 5mm bungee cord to be fitted between a fabric canopy cover and the clip.
I am not a pilot - use at your own risk.
