Yes! I think that is the right part. I will proceed with an order. Thank you very much for your assistance. This is such a great service.
Can you explain the 'options'? I don't know what to select...
The stamp option represents the strength of the channel balance. Looks like your original was 26 4, which often corresponds to our 2640 option. However, I recommend that you weigh your window sash and compare that weight to the rating shown for the 2640 just to be sure.
The weight of my window sash is 22.5 lbs so you are absolutely correct. Thank you very much!
