I have two windows in need of balances. The home was built in 2001. There is no make or model found. The metal channel (without the ends) is 31" long. The metal channel sides exact width is 19/32" and the bottom of the "U" channel is 9/16". Stamped on the channel was 3040 BSI DL.

I need four of these.
Thank you!

Hi Greg,

Thanks for posting! Your channel balance appears to be the Series 350, equipped with a wingless top and a winged bottom shoe. Since your balance channel measures 31", you'll need the S350-31.

You'll need to select the 3040 stamp option.
