What do I need to replace window parts?

Question

Your offer to identify is a godsend. Thank You!

1/2"W x 30"L channel balance - 31"L if you count the plastic ends

32.6lb window

Stamped on metal: 29 6 of BS1

Both channel balances were NOT engaged with the window, but were instead pushed all the way to the top. I had to pull them down and only then found the clip to flip and then the window came out just as you mentioned.

With this combination of attachments, you could have either an S380-30 or S385-30 channel balance. You 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 2960 springs strength option for your new balances.

As for your top sash guide, we'll need to see an undamaged guide removed from the window to compare to our inventory here.

Thank you and let us know if you have any other questions or concerns.
