Series 152 Coil Balance Quote

Question

I think we saw the letter K on the coil, but am unclear. I'm not sure which weight to get, but I am pretty positive this is the coil needed because it goes with the pivot shoes I need.

Thanks for your patience during this busy season. I'm afraid I don't know what the K means either. There should be a number on the spring. If not, tell me the exact weight of the sash and how many springs are used per side and I can give you a recommendation.
