Today one of my gas struts detached itself at the window end, and in the process damaged the thread in the window fitting. I managed to jam it back in but clearly it's on borrowed time. Are these fittings Midas-specific or is there a source for them?
Incidentally I thought my 2 year-old strut felt a bit stiff for 80 Newtons so I checked it and it took 115 Newtons to shift it...
