Can anyone please tell me where I can buy the plastic hinges for my secondary double glazing. I had the room decorated and the painter took them off the wood, together with some plastic bits which go on the bottom to keep them open for cleaning. the hinges would have a hole in them so the bit on the dbl glazing slots over the top. I think I found them on the net but lost the page!
I don't want to have to chuck the two panels away but if I don't get the parts I will have to.
Many thanks for all replies.
