I have pleated blinds fitted in my conservatory but the blinds on one of the french doors keeps dropping down and the cords appear to be very loose. I understand that it is probably the cords that need to be retensioned and the bar on the bottom of the unit needs to be removed in order to do this. I am afraid to attempt to remove the bottom bar as it is not obvious how this should be done. Can you help?
