Sash guide and windows balance

Hi there!

Take a look at our 18-201 top sash guide. Compare our dimensions to your current hardware and see how they match up. 

As for your channel balance, we'll need to see some pictures of both your top and bottom nylon fittings.

Thank you for the additional pictures!

It looks like you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a spring strength option of 2640.

If you have any further questions please let us know.
