Window Sash Guide Replacement

A quick learner from S. California says:
Hello, I'm looking to replace my in-law's channel balances for their windows. For the last 10 or so years, they have used a stick to prop up most of their windows!

Just needed some advice on which take out clip, top sash guide, and channel balance to purchase:

1. Take out clip - ALL the windows did not have a take out clip attached, it was probably broken and thrown away in the last 10-12 years or so. Looking at the picture below, will the 16-002 clip work?

2. Top sash guide - many of the top sash guides are broken. The last picture of the top sash guide looks identical to part 18-008, so I assume this is the correct part.

3. Channel balance - The original channel balance is stamped 2740W and it is 28" in length. After some research it looks like the S390-28 with the 19-002 and 15-001 is the correct fit?

3a. Each window weighed on a scale is 20 pounds. Is the 2740 correct? Just want to make sure.

3b. How do I know the S390 is 100% the correct. I need to purchase 12 channel balances.

Thanks in advance!

Good morning, Daniel.
  1. Yes, most of the Series 390 windows used the 16-002 Take Out Clip.
  2. It appears the 18-008 Guide does appear to be close to your original, but make sure you check the dimensions of your original and compare it to that of the 18-008 to confirm.
  3. Yep, I think you got it right. Be sure to double-check the height and width of our bottom attachment and compare it to the 15-001 to confirm the Series 390.

    3a) Yes, if yours is stamped 2740, I do believe it will work for a 20 lb. window.

    3b) As stated earlier, be sure to check the measurements of your balance attachments, as they are what determine the balance Series.

Thanks Mike, all the measurements seem to check out and have ordered the parts already.

Thanks again.
