SASH BALANCES

Hi, Manuel.

It looks like you have a S350-30 channel balance. You'll also need to weigh your sash to determine which spring strength option you'll need. There is a chart on the S350-30's product page that explains how to choose your option based on the sash weight. 

If you have any further questions just let us know. 

Your window sash is the glass panel of your window that slides up and down. You'll need to remove your window sash and weigh it.

Take a look at the video below starting at the 0:22 mark, there is an example of a window sash being removed. Let me know if that helps.

With a sash weighing 9.8 lbs, you'll need a spring strength option of 2910 which is used for a sash weight of 7 to 12 lbs. 

For your sash guide, I'll need to see an undamaged version removed from your window, along with dimensions, to compare to our inventory.  

Our 18-166 is similar in design. Review our dimensions and compare them to your current sash guide to see if they match up. 

Thank you for your business, Manuel! If you have any questions that arise just let us know, we'll be here to help.
