Window Balance 29 6 XF BSI

Question

Hello,
The code on my 5/8" channel balances is 29 6 BSI. From what I've read, I need the 2960 channel balances. Do they come with the clips attached? I also need the top sash guides and some clips that attach to the window sash. Can you help me to identify which clips I need?

Thanks

I'm afraid the stamp isn't used to identify the Series, it only indicates the spring strength calibration. It's not a part number or anything. The only way to identify the best Series is based on the nylon ends, which I can't make out in your pictures. You can see our entire selection here.

As for the top sash guide, can you give me its dimensions? In the meantime, you can browse through our entire selection here, as well.
