ST Cloud Window Repair parts

A quick learner from Richfield, MN says:
I would like to purchase replacement window spring assemblies for a St Cloud Window, which is approximately 30 years old.
This window was new in 1982.

This is a vertical single hung window, which is non-tilting. Only the lower sash moves up or down.

I would like to purchase new channel spring counterbalance assemblies.
This channel balance may also be known as a block and tackle balance for a non tilt window.
The channel has a 3/8" width.
assembly length: approximately 24 inches
I looked on your website and found this information:


Stamp Option Sash Weight Range
23C 13 to 20 lb
original was 20 lb. So choose 23C
I would like to replace the spring counterbalance assembly on each side.
Do you sell those?
Please reply with the part number and price.

We do sell balances, but I don't know exactly what kind you have. I recommend looking through our Channel Balance Section to determine the proper match. Once you follow the steps shown, you will likely come across a wide selection to choose from. You will have to carefully compare the measurements and individual components for each Series to your own hardware to confirm the best match.
