Thanks for posting, Jack. I agree, our S400-30 looks like a good match. You will need to weigh your sash to determine the proper color tip option. Two S400-30 balances with a Red Tip can support a sash weighing 10 through 22 pounds, while the two balances with a Green Tip can support 14 through 26 pounds.

That's normal. Some non-tilt sashes are not made to be removed. You will have to try your best to calculate the weight, though. You could detach the balances, place a scale on the sill, then gently lower the sash onto it. It's not the most accurate thing in the world but it would be better than nothing.
