Thanks for writing in! I am confident that we can supply you with the replacement coil springs needed for your existing assembly. However, I'll need to confirm the weight of the sash.
Given that your assembly has two coils on it, I believe the window may be a bit heavier than 6lbs. Can you please confirm that the sash weight is 6lbs?
