my channel is stamped 3606.
I am looking at product code 350-37.
Should I select one of the optional choices?

You will have to select one of the stamp option choices, since that determines your spring strength. 3606 is a weird stamp, and I'm not sure which of ours is a match. I recommend weighing your sash on a scale and referring to the chart we have on the S350-27 store page.
