Thanks for posting. Sounds like you have a spiral balance. Before I recommend a replacement, can you tell me what the diameter of the tube is? Can you also tell me the weight of the sash?

Thanks! I would recommend our S900-30 with a Yellow Tip strength option. I'm afraid we do not carry the sash stop you need, however.
