Looking for window springs for old 1990 era Alpha brand non tilting window

Handy Person from Ohio

Hi I measured the spring assembly and it is 30" not counting the plastic ends. The stamp on it says B.S.I. 2930. Please let me know if you have a replacement. Thank you!

Here is the link to the pictures. I tried multiple times to add photos to this request but they would never upload. Please contact me if the link does not work. Thank you.

Hello, thanks for posting! It looks like you could have either our S380-30 or S385-30 with the 2930 stamp option. The difference between the Series 380 and the Series 385 lies in the depth of the shoe. Take a look at the picture below for more detail. Once you have determined this dimension you should be able to select the appropriate balance
