I've just bought a house with a conservatory fitted with pleated roof blinds. These blinds are too high to reach, so to draw them you have to use a special pole with a plastic fitting in the end. You reach the pole up and slide this plastic fitting onto a little clip fixed to the end of a blind, so it grips it, and you can then use the pole to pull the blind back or forwards.
Unfortunately the plastic fitting is broken. Any idea where I can find a replacement? There are no records of who manufactured the blinds.
