spiral balance replacement

Handy Person from Mobile Ala
Got a 58H x 34W in window, dbl pane. No way to weigh. Need to replace the spiral balances. Suspect about 25-30 lbs. Old balance does not have a color tip. Old balance tube is 3/8". Pictures of ends attached.
Which color tip should I use?

I would recommend our 3/8" Series 900 balance. Look at that first and see if it matches. You may need a Green Color tip, but I cannot be sure without knowing the length of your tube. Let me know!

Oops forgot to let you know. Length is 29".

Thank you. That would be our S900-29. For a 25 to 30 pound sash you may want our Yellow Tip, but I highly recommend weighing your sash on a scale to confirm. We have a chart on the S900-29 store page that shows how much weight each color tip can support, so once you weigh your sash just refer to the chart for confirmation.
