I have many of these Alenco windows that are malfunctioning.
Main problem is broken plastic caps at top of balances # 1.
For some I need to replace complete balance mechanism on both sides. Will order both sides for a few sets as all I look at seem half broken or badly strained. They are stamped 2790 DK 31. Please advise me of the part numbers that I need.
Thanks for your help. I will order asap.

Hi Fred,
With this combination of attachments, 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 to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.
As for your top sash guide, we would need to see an undamaged version removed from one of your windows, along with dimensions, to compare to our inventory. Thank you!
