The string on the rear shade broke and I can't find a diagram for restringing it. Mine has a spring attached to each end cap and everything I have found shows only ONE spring in the middle. Are there any step by step instructions available? I have fixed several of the smaller blinds before, but this one I'm not sure about. Guess I could just trade her in for a new rig. I ended up with this one because the kitchen faucet broke in the 3055. Naw, think I'll fix the blind, for now anyway. Thanks for any help.
