Some of the sashes are very difficult to raise and lower because the springs bind.
Are these replaceable or even
Balance identification for conventional tilt vinyl windows

I'm in the process of replacing spiral window balances in 20-yr.old conventional tilt vinyl windows. How do I determine the correct balance weight rating to order if there are no numbers on the balance? Also, some windows have jambs that have pulled away (old house) leaving the sashes barely hanging on to the jambs by the tilt-release tabs. Any suggestion as to how best to move the jambs back in? As it turns out, my windows have a spring wound around a steel shaft (see attached).

Hello! There should have been an outer tube over this balance. There may be part of it still attached at the top. Manufacturers use the diameter of this outer tube to determine the size. If it's 5/8" or 9/16", then I recommend our Series 600 spiral balance. If it's 3/8", we recommend the Series 900 instead. As for determining the correct weight rating, you will need to weigh your sash on a scale.
I'm not sure what your jamb issues may be. Could you show me a picture? That would help clear things up.

Hello, Paul,
The outer tube has cracked and fallen away on several of the balances. The balances do not seem to resemble the spiral balances in Series 600 and 900 you mentioned. Mine are more of a coil around a steel shaft. Are these replaceable?
Also, the jam appears to have moved away from the sash.

Our balances look like that on the inside, too. The only difference is that our outer tubes are metal, not plastic. You will need to try your best to measure the size of your outer tube to find the best match.

Hi, Paul,
I measured the plastic tube around the steel shaft and it's 1 5/8 inches around. Does that make sense?
Thanks,
Steve

Hey, Steve. It sounds like you're measuring the circumference of the tube. The important measurement is its diameter.

Hi, Paul,
The balances I have are 9/16 in diameter and have blue tips.
What's my next step?
Thanks,
Steve

Thanks! If the outer tube's diameter is 9/16", then I recommend our Series 600 spiral balance.
