I would be more than happy to help you identify this balance. Can you also show me the bottom nylon attachment? Both these photos show the top, but we will need to see the bottom, as well. Thanks!
Tom,
I went ahead and ordered the part you suggested. It was an exact match in appearance. Unfortunately, the tension is very weak. The window just falls down when opened. It should stay open at what ever level you open it too. I ordered 2 sets and had to use 1 because my old one broke. What I would like to do is return the one set that is unused along with my old hardware. Please take a look at the old one and tell me which item I should have ordered then I will reorder.
